Chevrolet - 1500 :: Running Hot / Temp Quickly Rises To About 250 Degrees When Driving
Jul 21, 2016
I have a 1992 Chevy 1500 5.7L V8 with 167,000 miles that is running hot. When I drive the vehicle the temperature quickly rises to just about 250 degrees and hovers just under the "red" zone. It never fully overheats, even on longer drives (50+ miles). It seem to run just fine otherwise. It is not leaking coolant and I have not had to fill the radiator. My first thought was that the thermostat was bad, but wouldn't that be an "all or nothing" issue? Where should I start looking for the problem? It has been going on for about 3 weeks, and I want to get it resolved quickly.

I 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?

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.

I have a 2002 Chevy Impala with the 3.4L engine. The car has 180K+ miles on the original engine. The coolant temperature started fluctuating recently. Going from 200 degrees up to 240 sometimes 260 degrees.
I recently had the check engine light on with the P0420 code which indicates a bad catalytic converter, I had that replaced and I was hoping that maybe the lack of exhaust flow through the converter was causing the overheating. It is still fluctuating however after the converter replacement.
The coolant temperature seems to go up when the car is idling but when moving it starts to go back down to normal. I had the cooling fan assembly replaced last year after one of the fans failed. These are less than a year old and are both operating as expected.
A little history on the engine. It originally had that crappy DexCool in it that then ate away at the cheap plastic head gasket causing oil to leak into the coolant system. This caused the coolant to turn into 'mud' within the radiator and eventually the head gasket failed completely and I had to have that replaced along with putting in ethylene glycol to replace the DexCool. Now when the coolant system was flushed, I am not completely sure that all that 'mud' was flushed out of the radiator. So the radiator may not be operating at full capacity. In fact, driving through the mountains this summer going up inclines, the car would tend to start overheating.
So thoughts on what might be the issue, radiator, thermostat, sensor, water pump, something else? I'm pretty sure it's not the sensor because sensors don't fail in this manner (they fail either high or low). I'm leaning toward the radiator because once I get some air flow across it, the coolant temp gets back to normal.
Also, the A/C is sometimes working great and blowing really cold and other times it is just slightly cold.

Our B5.5. wagon with 1.8t and automatic just went in for recall work. Embarrassingly, I don't even know what the recall was for, I only remember something about cars catching on fire.
Since we picked it up the AC only works for maybe 10 minutes at a time and then switches off. The engine temp gets really high and then cools back rather quickly. Occasionally the temp warning goes off. We scheduled an appointment to take it back in to the dealer but of course they can't take it till next week.
In the mean time, have any of you experienced something similar? Perhaps the AC goes off because of the engine temp sensor? Better to overheat the passengers than the motor? If so then the problem is the temp or the temp sensory?

I have an 88 Chevy C1500. It started showing low oil pressure about a year ago and I went with a heavier oil and oil pressure go a bit better.
Just changed the oil and now, when I start the engine cold, I show normal oil pressure. As the engine temp increases, the oil pressure goes down. When engine is fully warm, oil pressure shows 0 and "check gauges" light comes on.
Decided to put even heavier oil in but guy at parts house said it was probably the sending unit, not a worn out engine. I tend to agree because I drove it more and never hear any ticking or valve noise. Too cheap to replace the sending unit.
From the symptoms above, does thus sound right? Could the sensor somehow fail as engine temperature increases? Everything I read says oil pump failure is very rare.

Chevy Silverado.. The display of heat, location of air flow, temperature and fan flickers and changes on its own. Sometimes it works fine and blows out nice warm air. Other times it goes out completely and I have no control over any of it. It will just blow cold air. If I turn the head lights on it sometimes makes it go out completely. I have had the relay switch changed out and that was not the problem.

I have a 2002 Volkswagen Golf 2.0, I was driving and the temperature gauge starting raising pretty quickly. I stopped, checked the coolant and oil, both were at normal levels. The car cooled down pretty quickly, and I drove a little and it raised again. The heat is coming out cold despite the hot temperature. Overheating, normal coolant levels, no heat.

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 just installed a new Sachs flywheel and clutch on my 1995 Chevy 1500 4x4. Got everything back together, filled up tranny fluid and gear oil, bled the clutch till no air came out and it still won't shift while the engine is running. I can get it into reverse with a little grinding when in 4H, but that's it. The stick moves freely when the engine is not running. Checked the master cylinder and it is moving just fine. I have checked and did not install the clutch plate facing the wrong way. Any other guesses on what I can do before I have to drop the transmission again and redo the whole install?

When I put my foot down in 4th 5th and 6th gear my clutch slips badly but when the temp rises all is fine?
I only have 135k and no oil leaks, however my VF mounts are done could it be the engine moving a lot and slightly depressing the clutch?

I have a 2001 Chevy Silverado with the 4.8L V-8 engine. It acts like it is running out of gas ( the gas tank is over half full). The truck has sat for about 6 months in this condition without being started here in Sacramento, CA. I then replaced the fuel filter and for a few minutes it started and the engine ran fine (without actually driving it). A few days later I started it again and it now again acts like it has fuel starvation, it will rev up briefly then act like it is running out of fuel. I know the fuel pumps are the Achilles Heel of these trucks, but before I try changing it I was wondering if there might perhaps be another problem such as the new fuel filter plugging up quickly or possibly an electrical problem. I've always heard these fuel pumps either work or they don't work, nothing in between. This problem is intermittent but big enough the truck is not driveable. Is there any way to get a good take on the problem before diving into the fuel pump replacement and hoping that solves the problem ?

My 1990 Chevy Silverado with 5.0 liter, 45k miles has started a problem that the guys in my diesel repair shop don't know what to do. Last week it started to run rough, hesitating and lurching and not accelerating smoothly. It idles fine, or pretty well, but just doesn't run smoothly with any kind of acceleration. I drive it back and forth to work just 1.5 miles during the week. I took it on vacation a week before, so it's not from lack of long trips, it ran fine.
A guy at my diesel repair shop put it on his Genesis scope and all it would code is the O2 sensor showed lean, but we could see it switching from rich to lean and so on. I thought vacuum leak, but couldn't find one. PCV valve is good. EGR valve is ok. I changed the fuel filter yesterday and thought it ran a little better, but now has gone back to the rough running. What I can do myself to diagnose this? I do have all the tools and shop.

My 2003 6.0 has a coolant leak. It leaks slowly while not running and more quickly while running. I have about an 8 mile drive to work every day, I can make it there and back without having to add coolant but I'm cutting it pretty close by the time I get home. In short I go from the max fill line to bone dry in about 24 hours.
With the truck running I can see water getting slung around all over the front of the engine but the majority of it seems to be coming from around the two larger pulleys in the middle. I've read that this can either be the crankshaft seal or the water pump, any way to know for sure? Any other possibilities?

2004 1500 5.3 low oil pressure after using Lucas engine stop leak. No pressure at idle just below 40 when driving. Replace the sending unit and pressure improved for about a day. Just had a manual pressure gauge hooked up and it shows the same as cluster. No engine noise at all. I was informed that using Seafoam or another solvent could loosen up build up and cause damage. Trying to find out if using an engine flush machine may support. I am assuming that the cause of the low oil pressure is due to build up from using several qt of the stop leak over a four months. I am the only owner and I have always changed the oil according to schedule and have always used Valvoline synthetic.

1999 Chevrolet Silverado 4.3 ltr ....
I was riding along the other day at about 40 mph and my engine just DIED. No sputtering, jerking, lurching, etc.. I have a 1999 Silverado 1500 4.3.
Since then I've tried swapping the fuel filter out. When I took the old one off I did the blow test and could barely get a bit of air through it. Put in a brand new one. Still won't start. It cranks but it won't turn over. It's like it is starved for gas I suppose.
All electrical faculties are functioning seemingly normal. (Of course I have to charge the battery every time I want to try and crank it because it doesn't charge itself because IT WON'T CRANK!)
I've had to change the fuel pump twice in the past 2 years. The last time was about 5 months ago.
For the past week or two my "Change Engine Oil" light has been on even though I've had my oil changed a month ago.

2004 ford f250 superduty v10, truck has a cold run miss, no matter the temp. (0deg. or 100 deg.) when i start truck it misses for about a mile or so until temp. rises, after that it runs fine all day even if i park it for a few hours,next day same thing. I have changed all 10 plugs, gas filter, air filter, cleaned mpf censer, throttle body. Also it shows no codes, and there are no codes in history.

I have a 2003 vr6 with about 60,000 miles on it and it overheats. I can drive between 35-40 mph and make short trips no problem but when going any faster or accelerate faster than an old lady in a buick, the temp gauge slowly rises(or fast if i accelerate fast.) Until the "stop, check coolant" warning comes on(which i don't let get to that point.) it blows heat all the time, all the hoses get hot, I am no professional by any means but i have dealt with many different overheating issues with other vehicles but I am kind of stumped at what to try first so i don't end up replacing something that doesn't need to be because i do not have the extra $ to do so. The problem started when someone put dirt in my coolant, I flushed out the system twice, the second was just to see if anything else had loosened up that I may have missed the first time..

I have a 95 chevy silverado. 305 with an automatic transmission. I was driving down the street at about 30mph when the power went out on me.
The engine stayed on and all lights stayed on. I could rev the engine but the truck wouldn't move.
I then had a friend tow to my house and i let it sit overnight trying to decide what to do next.
The next day I went out and started it and it and was able to drive it again for a short distance at low speed and then it did the same thing again.

I did an engine swap for a junkyard motor my 4.0 ohv had a very bad rod bearing so I got one from the junkyard with 117,000,or so they say.Anyhow, after its all said and done it runs perfect except the temperature gauge seems to not get as high up on the gauge as before after sufficient driving(it used to run about middle of the gauge) it drops low at idle then goes up and stays up then goes down.it still has good heat, doesn't seem as good as before tho.I changed the thermostat also.
