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...
View 6 RepliesI have a 2001 Miata. It's been over 100 degrees daily lately. The AC will blow sort of cold for about 30 minutes and the temp gauge will move towards the H hashmarks. If I turn the AC off, the gauge will slowly drop. I've also noticed that the amount of cold air is decreasing as time passes. In fact, the other day, the system was blowing air hotter than the outside temperature after about an hour drive.
The viewing glass has bubbling stuff flowing thru it. The recently flushed radiator is full as is the overflow reservoir.
I am trouble shooting my temp gauge. I have a 1997 f350. I brought the truck a year ago and i have still not fix this problem. I install a new temp gauge and nothing changed. When ever the truck is running it reads cold and doesn't budge. Ive read that the gauge can be broken its self but during a few hot times over the summer. The gauge began to rise slower, never reaching normal temperature. A few times i messed with the heat and the gauge would shoot over the normal temp. The truck seems to run at a good temp sometimes hot though. The tube on top of the radiator is hotter than the bottom also.
View 3 RepliesI have a 2002 F-350 6.8L, 4x4, crew cab, 8' bed, SRW, trailer tow pkg. I purchased it new in the fall of 2001. The truck currently has 54,000 miles on it (only gets used when I need to tow/haul something). It's kept in the garage and is in near showroom condition.
Everything on the vehicle is 100% functional except the transmission temperature gauge. Even when the truck sits for weeks, the needle will move to mid scale as soon as the key is switched on - haven't even started the engine yet! Put the scanner on it - no codes stored.
I'm attempting to trouble-shoot the TFT (transmission fluid temperature) sensor. Found some documentation online on the 4R100 transmission. It shows an electrical connector on the solenoid body with pins for the thermistor (so I can measure its resistance). However, I can't find a connector anywhere on my transmission that even remotely resembles the diagram I found online.
Question 1: When you first get in your vehicle and turn the key, does your tranny temp gauge read "cold" just like the engine temp gauge?
Question2: Does my truck have the 4R100 transmission? How can I verify that?
Question3: Looking for documentation on what connector and which pins are for the thermistor?
2002 S-10 2.2L ... Started noticing my temp gauge running around 170 degrees as it gets cooler outside. I changed the thermostat and noticed that the connector to the temp sensor was cracked, changed that too. Had to warranty replace the temp sensor because the first one didn't register on my dashboard gauge. Still didn't get heat above 150 degrees.
Warranty replace the new thermostat and still not getting heat above 150 degrees. Radiator cap test bad at 15psi, replaced radiator cap and still not getting heat above 150 degrees. The engine is running cool and the cabin heat is not as hot as it has been for the last 5 yrs. There are no engine codes stored, anti-freeze leaks and level is correct.
I'm lost as to why all the sudden the truck starts running cold and won't build heat.
The truck I'm working on is a 2003 f550 with a 6.0, and 382000 kilometers. My service truck died on me couple days ago, while running. As I rolled to a stop, I noticed that my temp gauge on the dash dropped to cold. (Truck was hot). Tried starting, and I have a crank, no start situation.
After towing it to my shop at work, I hooked it up to my scanner, and found that the pcm will not communicate with the scanner (otc genisis). I have no injector buzz with key on, wait to start light comes on for an abnormally long time. I have 48.3 volts on the ficm,(4 screw), and haven't been able to find any chafed wires as of yet.
I have a 2004 3.0 V6. The dash temperature gauge doesn't move just sits at the bottom 50C. (Canadian metric)...
I would like to locate the sender for the gauge to do a little testing. I removed a whack of plastic but nothing was obvious.
I recently replaced my alternator. I thought I was very careful not to make anything worse but now when I'm driving I have temperature issues. When stopping or slowing down my temp. gauge goes all the way to cold, then as I accelerate the temp gauge rises to the middle. It has not gone past the middle and has never done this before the repair. Also, the truck has never overheated or had any thermostat or cooling issues before.
View 6 RepliesI have a 2004 Grand Prix and it is displaying the symptoms of overheating but the temp gauge is not going above normal operating temp. I replaced the thermostat twice, and after driving for about 10-20 mins coolant comes out of the overflow. I'm at a loss, I'm thinking temp sensor(?) But I don't want to keep throwing unnecessary money into it. The fans work fine, the heater blows as it should.
View 8 RepliesI have a 2012 Crew cab Silverado 5.3 V8 with the towing package. When I pull my travel trailer (approx. 5000 lbs), the water temp stays 1/2 guage and the tranny temp is 170-190, however, on steep hills the water temp guage goes 2/3 to 3/4 guage for a short time and the tranny temp reaches 200-210 degrees. Is the elevated water and tranny temps okay or should I try to reduce them back to the normal range. What is the max temp I should keep the tranny at?
View 9 RepliesMy 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???
View 1 RepliesI 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 95 ford f350 when u run it with the heat on the truck temp gauge says its overheating the heat will go from nice and hot to ice cold as soon as the temp gauge goes up to the red. I replaced the thermostat also checked for coolant leak cant find any but truck has strong anti freeze smell and the radiator keeps going low on coolant.
View 2 RepliesMy 94 Ranger 3.0L 5speed 2wd temp gauge is staying on the cold side but the heater is working good and I used a laser pointing thermometer at the thermostat housing and got 180* after running for a while and I also noticed that the fuel economy had gone down along with the power. I was getting 340 miles to a tank but now I'm getting 280 per tank.
View 12 RepliesI have a 1991 Silverado C1500 and when I push the heater button to on, the thing just goes absolutely crazy. Instead of one little indicator light, that is suppose to show hot, it lights up all the way across, like a pinball machine that has tilted. The heater air does not get hot and the temp indicator on the dash (separate guage) will not move off of cold. I am going to replace the thermostat, but what is going on with the darn temp gauge?
View 1 Replies2006 F150 King Ranch. My Air Conditioning no longer blows cold air. Additionally, the Temp Guage is pegged dead left. No movement at all even at normal operating temp. I've had the dealer replace 2 sensors and a wiring asy (XL3Z-14A411-AA). I still have the same problem. No cold air and the gauge is still pegged dead left.
View 3 Replies2006 camry temp gauge goes past H while car is running at any time. Fan still works anti freeze in radiator anti freeze in reservoir. When take the key out the ignition. Temp gauge drops to the middle(normal position) 15-20 later then gauge drops to C (normal position when key is out ignition). Car runs fine no steam no leaks no funny noises. Car has 68k / 4cycl.
View 1 RepliesI am going to install an aftermarket gauge on my Excursion. Just would like to know the best place to install the probe. Hopefully it isn't that hard.
View 14 RepliesAlright so noticed the other day that my temp gauge was staying pinned at cold. every once in a while it will jump up to the normal range but not for more than a few seconds to a minute before it drops back to cold. I just bought the car so I've still got a warranty from the dealer and im fairly convinced that I don't have to bee too concerned with it over heating because when the gauge DOES register its saying normal. just thought id ask here before i drive the 2 hours back to where i bought the car.
View 11 RepliesI have a 2000 monte carlo ss. A few months ago the check engine light came on, the temp gauge stopped working, and after shutting the car off you can hear the fan running for about 10-15mins after i shut it off. I assumed it was the thermostat, so that was the first thing i changed. For the first few weeks everything seemed fine. No check engine light, temp gauge worked...then today suddenly it all started happening again. What could be causing it if the thermostat has already been changed? what should i try next?
View 2 RepliesI have a 2007 Camry with the 4 cylinder engine and about 90,000 miles. I just changed the oil and took it for a test drive only to notice about 1/4 mile down the road it was running very hot. My a/c began to get warmer and my temperature gauge was at the "H". I pulled over and it immediately cooled back to normal operating temperature (in the middle of the gauge). The car was left running this entire time and I began my way back to my destination. It never ran that hot again but when I would slow down to an idle I noticed at times it would go up in temperature, but not as hot as before, and go back to normal temperatures. Sometimes during a drive it would fluctuate a little bit, but nothing as much as it would on the very start of running this car cold.
So I opened my hood and looked at the reservoir and noticed I do not see any fluid in there. I guess I should add that I have never flushed or changed the antifreeze b/c I did not know I would need to change it until recently at the 5 year mark. I also notice a little but a pink crystals (about the size of a pencil head) on a bolt at the top left of the engine, right under were the oil cap is. But that is all I noticed. No leak in my driveway or other areas of the engine. I must note that I did the oil change myself and it was nice and black, so from my experience it does not appear to be a head gasket, b/c I would assume it would be milky in color if that was the case.
