I am losing heat intermittently and temperature gauge spikes out intermittently. Got down to intake gasket and it is visibly bad but wonder if i should keep going to replace head gasket?
View 4 RepliesI have a 2002 Nissan Sentra. In Nov. 2010 had inspection done and replaced upper radiator hose at that time. Right after that, I had no heat and the temperature gauge would go up to hot but then come right back down. Brought it back to mechanic, changed thermostat and both things ok only part way home. Started riding with coworker only driving to her house 7 miles away and still temperature gauge up and down, stopped driving completely in Feb. Just brought it to dealer who replaced thermostat and worked fine all the way home and then started all over again the next day. Seems to happen faster at higher speed but will eventually do it in any driving conditions. Today service engine soon light came on. Obviously not thermostat problem. Could it be water pump? Dealer did pressure test and that came back fine so no head gasket problem although don't have a lot of faith in that since problem still exists and they thought thermostat would fix it.
View 19 RepliesSo for the past couple months every time I get on this incline on a freeway transition my temperate gauge spikes to red and the notification center tells me the car is overheating and to pull over a couple seconds later it goes back to normal. This has happened about 7 times now over the past couple months. 07 LS460 just hit 80K miles.
View 14 RepliesThis Dakota has the 3.9 with about 240.000 miles. New battery and Alternator within the last 18 months.
The other day after driving about 12 miles the chime "Check Gauges" come on and I noted that the voltage gauge on the dash was buried at Max.Pulled over shut off the truck and popped the hood. No visible problems. Got back in, started the engine and the gauge went back to it's normal position. I had expected to see smoke from the alternator or the battery blown to pieces from the overload. I also noted that there was no excess heat at the alternator or battery.
I picked up my DVM from the shop to carry along and have driven at least 5 trips over 15 miles since. Today the same problem occurred, but by the time I pulled into a close-by parking lot the meter went back to normal. I checked the voltage at the battery and had 13.25 volts with the engine off and 14.40 volts with the engine running. I drove another 40 miles with no problems.
Tomorrow I plan to run a lead from the battery into the cabin, so I can monitor the voltage quicker if the problem reappears.
My 2005 Hyundai Elantra GLS has had 0 problems. It has about 132K on it, but it's still awesome.
I was stuck in some nasty traffic the other day in 95 degree NC weather, and was idling for about 15 minutes with the AC on. Out of nowhere, it felt like my AC got warm and I saw my coolant temp gauge spike from just under midway to 3/4 of the way. Unsettling.
As soon as I got on the gas and drove for about 5-10 seconds, it dropped precipitously back to normal. I was able to recreate this behavior once I got home. Normal driving results in normal temperature. Both fans appear to running.
I have a 1999 Ford Expedition. A couple of days ago The engine started losing coolant as soon as the engine cooled. I replaced the coolant only to lose it again when the engine cooled. I was told that it is more likely the intake manifold gaskets leaking. It seems they are right. What is the cost to repair if I take it to a mechanic?
View 1 RepliesJust about every trip i take my temp gauge pegs and dinger goes off and check gauges lights up in the message center. It eventually will go back to normal or if i shut key off and restart truck it goes to normal. im guessing it is the temperature sensor for the gauge but not sure?? If it is, where is the gauge sensor located?
View 14 RepliesMy wife was driving expedition 2001 Saturday, the oil light came on, followed by check engine light. The needle in the gauge dropped to low in a matter of seconds. She exited the first exit, pulled into a Chevron and added 2 quarts of oil. When she restarted, the oil gauge moved up but engine was knocking a little. She turned it off. Sat for a bit and tried again, this time the oil gauge read L again and engine still knocking. There was no leak under the vehicle. Is the engine blown?
View 4 RepliesAbout mid-October I noticed when it as real cold out and I had the heat running whenever I would come to a stop I noticed there is very little to no heat coming from the vents, despite the engine being warm and running at operating temps. At the time I was working for a shop and I asked one of the mechanics what the problem was. He said that it was the radiator not having enough coolant.
Turns out when we pulled the cap the coolant res, was just about bone dry. So we added in about a gallon or so of coolant with the truck running and sure enough at idle the heat was back.
Fast forward to the last couple of weeks and when I am sitting at idle again same thing happens. So somehow the engine is losing coolant. Its not ending up in the oil (no white on the dipstick) and there is not a coolant leak. As it sits there is 255,300 miles on the truck now. 1999 5.4L F150....
I have a 06 f350 6.0. I'm losing hear at times. My temp gauge is right in the middle like always. As soon as I let off he throttle or come to a stop the heat turns cold and blows out cold air!
View 2 RepliesThe car is a Taurus Wagon. It does not put out any heat. It is a flapper door issue. I tried changing the blend door actuator as the old one did not move when the temperature was changed from cold to hot. Unfortunately the NEW one doesn't either, nor does it move when left hanging, not in the dash. It is an automatic temperature control unit. When I had the actuator out from under the dash, I could move the blend doors easily with the little lever, and get excellent heat, so I know it's not a heater core issue.
Everything on the dash unit, which includes the stereo/radio controls and buttons to shift the air from floor to defrost seems to work fine. It shows the desired temp, but won't go to it. I have checked two fuses that are supposed to feed the HVAC system. I have even installed a different dash unit from another Taurus to see if it made any difference. That included a second temperature sensor, the "Y" shaped thing near where the white hose connects to the back side of dash unit.
I admit, I'm lost. I don't have a good wiring diagram, and don't know if I could read it well enough if I did.
Is there a relay or something in the system between the controller and the actuator that I don't know about?
Which wire or wires in the multi-pin connector that plugs into the blend door actuator are supposed to be hot at what point?
I have an '09 Plat SCREW with the dual zone climate control. No matter what temp I set I'm only getting cold air out of the drivers side IP & floor vents as well as the two rear facing vents in the top of the center console. Since I'm out of warranty I'm wondering if there's anything I can check or fix on my own without taking it into the dealer.
View 9 RepliesHow to install a temperature gauge for the 4R100 transmission in my 1998E350 w/ V10 engine Van? what's the normal temperature for this transmission?
View 8 RepliesI have a 2007 6.0 with 260k on it losing gauges and radio intermittently while driving. Lately 2-3 times a day, lasting 3-4 seconds a time.
I have heard it could be the shift lever, instrument cluster, fuses, etc. I have kind of ruled out fuses based on the behavior of the failure.
Looking for a second opinion before I start taking the dash apart or send it in. The truck just can't be down for a long time right now.
I have a 2011 xlt extended cab with a 2.3l 4 cylinder. The truck is great... I put 120,000 miles on it in under a year.
But about a month ago the temperature gauge started malfunctioning. for what ever reason -- the truck is NOT over heating-- the gauge would increase past the "H" and then the temperature light would come on. Because the truck thinks it's overheating -- the engine goes into a "safe mode" and runs with no power. When i shut the motor off and turn it back on temperature gauge resets and the truck will run fine.
Then in another 50 or 100 miles it will do it again. Why is it doing this? I took it to the dealer here in Columbus, Ohio and the mechanic installed a new thermostat and a new "control modulator" (and a part -- not really sure what it is called) anyway, the truck is doing the same thing and the mechanic still does not know
Having a problem with my temperature gauge inside the truck. No matter how far or long I drive, the needle barely moves off of cold. Would the thermostat be the likely suspect? If not, what else could it be? There is no "check engine" light on and my ODB2 reader reads a temp of around 70c solid. If it is the thermostat, where is this part located in the car and would I need to replace JUST the thermostat or are there gaskets/housing-type things involved as well.

View 9 RepliesI have a 1992 Aerostar 3.0L end my temperature gauge on the dash doesn't move at all. Stays all the way to the left. I read on other forums that to make sure the gauge and the wiring are ok, i need to connect the wire that goes to the sensor unit to the negative of the battery. Gauge should go all the way to hot when the ignition switch is put to on position. That was exactly my results. So, i replaced the temp sensor unit but still gauge doesn't move. I didn't use any sealant on the threads when i installed the sensor. Connector looks ok. The engine warms up fine. I really don't know what else to think or do.
View 11 RepliesI have a 2007 f150 with the 5.4 in it and today I was driving it and my tempreture gauge randomly shot to cold and check engine light came on. Also can't even find the dam radiator cap due to too much plastic!!!
View 2 RepliesI have a 2001 ford ranger xlt 2.3L and the temperature gauge has been staying a cold. And my heat doesnt heat well. I'm guessing I need to replace the thermostat. Before I do that could it be anything else?
View 9 RepliesI have noticed that my temperature gauge is indicating that usually my truck is running very cool. It seems that it is also somewhat erratic. At times it indicates what I would expect a reading in the middle of the gauge. Other times after running a while it will drop to the lower end (cool) of the gauge and stay there.
I am guessing that the thermostat is sticking open. Is there a way to test the sensors to see if they maybe bad? I have a 99 ranger with a 4cyl. It looks like I have two sensors. If one is bad, how can I determine which it is?
