Ford A/C :: 1977 F100 - Temp Gauge Reading Higher
May 25, 2017
I have a 77 F100 2wd 302/c4. I recently replaced the rear plate to my gauge cluster after it crumbled to pieces. I swapped all the gauges to the new plate minus the fuel gauge since it decided it couldn't live if livin was without the old plate. I have a gauge cluster out of my 75 and decided to swap in my fuel gauge from that one. I put the cluster in the truck and fire it up for 10 mins or so and everything is working great except the temp gauge isn't moving. I figure it romeo and Juliet with the fuel gauge so I just swap all gauges from the 75 into the 77 cluster except the speedo. Same result.
So I figure its the sending unit now and maybe both gauges were fine to begin with. I put in a new sending unit and now the gauges works but the needle sits on the P in the word TEMP on the gauge which makes me uncomfortable. That's about 1/4 inch or so from being past the end of the gauge. I don't believe the truck is running that hot. The gauge was more or less straight vertical before the swap sitting right at the end of the E on TEMP. Did I get a bad sending unit? Is it a bad ground on the gauge? Was I supposed to take off the teflon tape that came on the threads of the sending unit? I'm gonna try removing that first and see if it lowers the needle.

It is a garage queen 1994 4.0 AWD with 42,000 miles in nearly perfect shape. Except for the dent in the rear on the passenger side.
I have posted a picture of the dash when going down the road. As you see the engine light is on. It comes on intermittently, pulled the codes, indicated MAF, 02 sensor, running lean/rich. Runs like a champ, no hesitation, still gets up and goes, gets the appropriate gas mileage. I replaced the 02 sensor with the original Ford Part. Didn't cause the engine light to stop going on after about 20 to 60 minutes driving, sometimes it doesn't come on at all.
Could this thermostat be running too cool and causing the engine to throw those codes? Would gladly take it to a mechanic, but seems like it might be a fishing trip with my dollars for them. Next I was going to replace the MAS myself, easily done with the original remanufactured part at a cost of 150.00, 70 for the core, but don't want to chase my tail with these engine lights on when it runs nearly perfect.
Have sprayed the MAF. Checked for air leaks anywhere. Done all the things I could do by just lifting the hood.
So the picture shows the Temp gauge barely touching the N flying down the road at 70 on a level surface, outside temp about 60. Reading the posts says they all run in the cool section of the temp gauge.
So the question is, do they run this cool? Heater works fine and the gauge goes up past the N resting before the O when going up hills on the way to Tahoe. Is this a thermostat problem on a 20 year vehicle with low mileage, or am I going to have to bite the bullet and let the mechanic go wandering through the vehicle?

I have a 2001 Excursion Limited V10. 146000 miles 2 wheel drive. I have had it about a year and this is my first winter to really have experience with her.
When the outside temperature is very cold and the engine is cold from sitting all night, at start up, the oil pressure gauge reads nothing and the oil pressure/temp idiot light is on. Only does this during the first very cold start up or after sitting and engine getting very cold again.
I can drive just a short distance (2 blocks) and both gauge and light go to normal and stay there for the rest of my drive. I am using a quality 5/20 oil and filter and the level is good. Warmer days it has never happened. Truck runs fine, smooth idle, no "limp mode". She has not had any recent work done. All the other dash gauges read fine.
There is something about really cold temperatures that have to be causing the issue , I think. ??

I have a 77 ford f100 I am restoring. I have two factory am/fm radios. I bench test both with antenna male plug all the way in, and the fm works fine on both radios. The only way to get am to work, is to slide the male antenna plug all the way out till it is just touching, then if I jiggle it, the radio plays.

I have a 2003 Excursion 6.0. I didn't post this in the 6.0 section because it may not be just a 6.0 issue. (See what I get) On cold starts, anything under 150 degree water temp reading on the SGII. I get a CHECK GAGE light on accompanied by the check engine light. No codes read on the SGII pending or stored. Just some of the time I get a water in fuel light too. This tends to go out fairly soon after driving. (Even after I just drain the fuel pump it still happens.) other issues that accompany the lights are as follows.
The trans temp does not give a reading to the dash. The oil temp does not give a reading the dash. Both show proper temp on the SGII. When in reverse the back up alarm beeps as if something is behind me. And the auto door locks will not activate after 10 mph. The tach also will not show a reading in the dash. SGII shows the numbers. Now the kicker, this ALL gets resolved the instant the water temp hits 150 degrees. The only lingering issue is the that the tach will surge or drop every now and then. The tow/haul light does not come on when this is going on. I've checked the battery terminals all are clean. Both batteries are brand new.

My temp gauge (which very seldom deviated form its position) is showing above normal temps. Yeah its over 90 here but this is unusual for my car to run hotter. I put in a new thermostat about 3 years ago. I've also been adding water/anti-freeze because there was a small leak (that I finally found in the hose) that I corrected. Could it be that my mixture isn't a 50/50 mix or is it my thermostat again? They say they don't last long anymore???

I have a 2005 Toyota Matrix with 250k on it. It has run like a champ so far, with the only problem being an ECM recall last year. I have noticed a few problems recently; the heat blows cold air for quite awhile, and the temperature gauge, while not reading hot, sort of fluctuates between normal and a little warm. When the ECM was being replaced, the dealer said the serpentine belt was overdue for replacement, and I know he's probably right about that. He also said the water pump needed replacing, although I have never seen any signs of leaking. This car has been a champ, and I'd like to try and get another 100k out of it if possible. I'm pretty handy around a car, I've replaced an alternator and radiator before, and I'm working on a limited budget, so if any of this is doable by me, I'm up for it.

I was recently given my first Volvo. Its an 88 240dl. While driving my temp gauge climbs up to the red and sometimes hovers inside of it. It normally climbs up at stop signs and comes down on straight always then climbs right back up close to red. When the gauge was in the red i stopped the car and popped the hood open to see that the engine was not actually overly hot.
first i replaced coolant. nothing
then i replaced the thermostat. nothing
flushed radiator. nothing
Today i finally had enough and decided to switch out the water pump with a new one hoping that it would solve the problem seeing as it still had the factory one on. It did nothing. the gauge continues to climb up. I did replace one of the two senders in hope that it would fix the gauge reading but nothing.

Every now and then when I slow down the temp gauge drops about 1 notch below its normal 200 reading. It's nerver done this before. Car runs great and heat is strong. Is this a sign of a failing thermostat? If so, where is the thermostat located, is it hard to replace, and should I get OEM or is OTC ok? Car has 89K on it.

I have a 98 trans sport and the temp gauge is reading low. Only on the first line when driving then when i pulled into the garage it went up one line and heat got warmer. Felt both upper and lower hoses and i can press them both in Fluids are full no leaks anywhere. oil is good tranny fluid is good. I just got it on a trade it runs and drives great no problems at all.

I have a 2006 Jeep Liberty 3.7L that has a temperature gauge on the dash that reads an overheat when driving. The oil looks normal, there is no white smoke, no bubbling from reservoir. I have replaced the following:
Radiator
Thermostat
Water Pump
Coolant Temperature Sensor
Coolant Reservoir Tank
I am not leaking any coolant and the reservoir level has been fine. I have let the vehicle idle for 20+minutes, with no overheat. When I drive it around, the temperature gauge will read an overheat. When I stop the car and pop the hood, the engine is not overheated and both rubber hoses to/from radiator are flowing the coolant. The only thing that will bring the gauge down is turning on the heater full blast. Could this be the gauge itself being bad? Could it be a short in a wire somewhere? I had thought maybe a head gasket, but have no symptoms of a head gasket.

Lately my engine/coolant temp gauge has been screwing with me. It is either been almost at 190* or dead 90-100*
It seems to go up when in the lower RPM range (idle-2000) and goes down when in the higher range (4000-redline I suppose).
I stayed at or above 4000rpm on my way home from work for 3-4 minutes and it was almost at 90*...went to 5000 for 2 minutes, same thing. I shifted to 6th and it rushes to 190*.
So is my sensor bad or what?

I was sitting in my car on lunch break. I noticed the temp gauge was higher than normal. Then I noticed a little steam coming out from under the hood. When I checked, there was antifreeze leaking out from where the tube connects to the overflow tank. It didn't look like there was a hole in the tube, it was squirting out right where the tube connects to the tank. I turned it off, and had to go back to work. I'm not mechanically inclined. When I got off work, I put a bottle or Bars stop leak in and filled it back up with antifreeze. Started it up, didn't seem to be leaking. Drove it home. Any time I am idling or cruising, the temp gauge will go up to the 3/4 mark , when accelerating it will drop to between 1/4 and 1/2, which is where it normally was.

Well, I'm still driving the same old 1998 Honda Civic DX two-door coupe, and I've got a problem with overheating. The temperature gauge needle doesn't get quite to the red, but it's popping up higher than usual, and I'm concerned to see it getting anywhere near the red. It usually spikes when I get off the highway and stop at a light, but it also does it occasionally in a drive thru, and recently, I discovered that when I give it a little gas in neutral, it brings the temperature gauge needle down to normal.
Here is the history of recent repairs and troubleshooting:
-About 3-4 years ago, I had a leaky radiator replaced, so the one that is in there isn't very old.
-Last year I had a mechanic replace the thermostat, the radiator fan, and the radiator cap when I started having this problem.
-A few months ago, I had the timing belt serviced (the entire kit, not just the belt), but since the water pump looked fine and the car has so much mileage (275,000 miles), I opted not to replace the water pump. (I regret that now. I usually replace the water pump with every other timing belt, but I've learned my lesson.)-I've been to several shops to get a diagnosis, but they have a hard time getting it to overheat at all, so they can't diagnose it.
One guy suggested the water pump might be worn out (inside, without leaking outside). Another guy suggested that "if it was the water pump, you would know it's the water pump." Each mechanic has done a pressure test on the cooling system and a flow test on the radiator, and they all say they are fine. One mechanic theorized that I might have a very small head gasket leak, but nobody else thinks that is the case and there is no sign of coolant and oil mixing. Besides, the temperature gauge has never been in the red.
-One mechanic who tried to diagnose the problem recommended replacing the plugs, plug wires, rotor, and distributor cap. After doing that, it is running better than it was, but that didn't resolve the overheating problem. He also retarded the spark timing, but it is self-adjusting, so it re-advances itself after a couple days of driving. I can hear what sounds like minor knocking, but it's always made that noise since it was new.
-Everyone who has tried to diagnose the problem says the thermostat is opening and closing as it should, and the radiator fan comes on and shuts off when it should.
I'm done getting second and third opinions, and I'm ready to start throwing parts at it. Do you think I should start with the water pump? What are your thoughts? Don't tell me to replace the car. I just bought a new motorcycle.

Coolant temps getting much higher than oil temps under load. Is there any problem that could cause this other than a bad temperature sensor? Reading temps with an Edge CTS 2 monitor. Think I'm going to hook up a mechanical gauge in the morning and see what it shows.

I'm about to dropkick my oil gauge but need to make sure that it is the problem. It WAS working but recently stopped. Here's what I have:
Dolphin electric oil gauge as part of their 6 gauge kit...fairly new oil sending unit (it's been on a year or so but the truck is not road worthy yet)....312 V8 and all of this is in a '53 F100.
I have verified, by hooking up a direct oil pressure gauge, that there is oil pressure. I have checked my wiring (it is all new from about a year ago) and it is all hooked up. My question is with the oil gauge removed, how can I hook up power to it and see if it works?
I could just go replace the sending unit but being that it is new I'm not going to throw parts at it just yet.

Does the prius c heater work if we set inside temp higher than outside temp ?(Difference is 2 or 3 degrees ). Is the heater take more energy than AC ?

02 6.8 4x4 excursion. When I start the truck cold, the trans temp gauge immediately moves to "running" temp. Not really sure how this happens, I'd figure that if the xducer was trash it would ride all the way high or all the way low. What's happening here? I'd sure like a functional gauge...

I am a beginner when it comes to anything involving wiring. I am looking to re-wire all of the wiring coming off of the instrument cluster gauges. Once I have completed all of the wiring on the gauges, I may feel confident to move onto something else. As of rite now, it appears as though my truck is still running on all of the original wiring, and over the past few weeks, I have been having many wiring related issues. I found a schematic that includes the wiring for the gauges that I am going to go off of. I have a couple of questions before I begin.
1.) On the schematic, it shows connectors such as "Connector G" which is moving all of the gauges wires to there locations. Do I need to use a specific Ford connector, or could I purchase a new connector at any hardware store that carries them? As far as I am concerned, connectors do the same thing as all other connectors. (Let you connect and disconnect for easy instrument cluster removal.)
2.) I am not looking to purchase one of those expensive wiring harnesses. I would like to just purchase some wire that I can cut / use myself. What brand / type of wire should I be looking to purchase? I do not care if it is striped / colored as I will use wire tabs to name / label each wire.
Other than that, I feel confident enough to attempt something such as this. Here is the wiring schematic I am going to use.....

The water temperature in my 97 3 liter Aerostar seems to be higher than I would expect when climbing a mountain road with the aircon on full. It was only about 75 degrees F and the elevation went from 300 feet up to 2,400 and the gauge was at 3/4 to the red zone.
I don't use aircon much here in the south Bay Area but as I recall the gauge on both my 96 and 97 Aeros was straight up during such climbs. The 96 is out of coolent so I can't compare it now.
The reason I'm rather concerned is we are about to leave on a 2,500 mile road trip with 4 people and lots of gear through Nevada and Utah and we'll climb a lot of passes in 90 degree heat or higher.
The mileage is about 135k and the water pump was replaced about 2 years ago. The radiator was replaced at about 100k.

My outside temperature reading on my '05 (6.0 PSD EB) Ex has recently gone black..no reading. I haven't noticed any other issues, just no outside temp readings... Do these sensors go bad or ? Is it a big deal to change them out?
I was told it should be located just to the side of left hand (drivers side) headlight behind the grill, a small black cube (approx. 1 inch square) with three wires coming out of it. However, I'm not finding it there.
Where is the temp sensor located? Is there a fuse covering this sensor?
