Caprice :: 1992 Classic V8 5.7L Randomly Overheat
Jun 20, 2013
Last summer the car would randomly overheat and we would switch the heater on and the temp needle would nose dive into normal range in 30 seconds. It made me think that maybe it wasn't really overheating.
This summer its started again. It gets almost into the red within minutes of driving it. There have been times where I turned and the needle went from almost the red zone to the normal range. Making me think its not overheating, but that nagging feeling tells me I need to know for sure.
The car will overheat within a few minutes. There were no visible leaks. I replaced upper and lower radiator hoses and refilled lost fluids. Driving it the first time, the upper radiator hose popped off and overheated. I initially thought it was the clamp being faulty so I bought a new clamp. Installed new clamp. Same thing. Same hose popped off again. Put it back on and its leaking fluid around the hose some how.
I know the lower hose has a coil in it to prevent collapse, should the upper too (haven't seen it collapse)? Why might it be leaking around the hose?
Next is the thermostat. That will be replaced this weekend. I'm pretty confident that it isn't the engine block cracked or a bad head gasket.
How should I remedy this hose issue and what course of action should I go for next? Water pump?

I just got a 1985 Caprice Classic, V8 305. I sometimes have trouble starting it when the engine is cold. When I received the car from a family member, he gave me some spray for the carburetor. This does the trick, but I would like to fix it so that I do not have to resort to this.
The visor has some instructions for starting the engine. The directions say to depress the gas pedal once before trying to start, and 2x when it is very cold outside. I'm concerned that the car won't start at all when the winter comes.. Where should I start to troubleshoot this issue?

Last year, around Jan/Feb, our temperatures dropped down to about -30F, and I had a weird issue where my brakes literally froze. I couldn't push them at all. I let the car sit for a few minutes, and started slowly pumping the brakes, and eventually got them freed up.
A few months later, the brake line going to the rear popped. I eventually got it replaced. Then a few months later, the front brakes started scraping and squealing, and so I replaced the front pads and calipers about two weeks ago.
Now, the other day I was slowing down to make a turn, and my brakes completely went out. When they did, I heard a pop from up by the engine. I pulled over, lifted the hood, and there was brake fluid covering my hood, abs unit, and a small amount on the engine.

For the last couple of years, I've noticed the air flow changes from the floor to the defroster under hard acceleration. Not a big deal. This morning (7 degrees) the airflow was changing under light to moderate acceleration. It's a vacuum problem, but is there anything in particular I should be looking at? The car is running fine, no issues with stalling or hesitation.

My engine temp indicator shows overheat to the red line, however when I stop the car I can put my hand on the radiator cap and leave it there. No signs of any leaks anywhere. The top radiator hose on the drivers side is hot. Engine runs fine. Oil on dipstick clean. I can't find anything to back up my temp indication. What else I can look for? 1987 chev caprice classic brougm ls 5.o liter.

I put a new battery and the fuel tank is full but the car always has trouble starting. the other day i sat trying to start it, pumping the gas for 10 minutes or so. Nothing. I noticed some dripping under the car but it looked like coolant. Could this be something bigger? I have a new battery in. Do I have to go and start it every week and let it run for a few minutes? Any portable car jump start?

I have a 1992 celica GT 2.2l A/T. I was on my way home today from college and my car started to overheat right before i made it home. It was steaming a bit and the temp gauge was tacked out. when i pulled into my apartment i noticed a light brown colored liquid in my parking spot, and alot of it.
I saw this same liquid at my college campus and assumed it was a coffee someone spilled near my car, but now i know it came from my car. I haven't had a chance to check my houses yet as i just got home and my cars still really hot. I know its not power steering fluid b/c that's been empty all week b/c my reservoir leaks. Why my car is overheating and what liquid is coming from it. Oh also the liquid seems to be coming from the right front portion of the car.

I am having an issue with my transmission. Mine will not accelerate when in reverse, at all. When I take off in overdrive, the car revs up really high until about 30mph and then finally shifts and seems to drive normal at about 45-65mph,after that the car revs really high up to about 70mph (then i slow down). No problems with gear 1 and 2.

I have a 92 caprice 5.7. Vehicle had suddenly stopped ... Providing fuel to the tbi. I immediately checked relays etc all were good. Then I figured it had to be the pump because I didn't hear the whirl of the pump with the key forward engine not cranking. I replaced the fuel pump. Still same problem no fuel. I found the 20 amp fuse blown that sits next to the 2 relays. I replace the fuse then the fuel pump got energized as I cranked the engine it almost started but then the fuse blew again. I have a short in the circuit I believe. I don't have a wiring diagram,what else is on the fuel pump circuit so I can have a direction to start in to find a probable bad wire.

What is happening is that air will stop blowing through the vents randomly. We will be trucking a long with either a/c or heater on and all of the suddon it will stop blowing. I know the blower is on because I can toggle between vent and defrost. It will blow out of the defrost but will not through the vents. It can be anywhere from 1 to 10 minutes and all the sudden it will start blowing through the vents once again. It just doesn't blow through the vents. This is a 1992 E-350 with a 460 in it.

I have just inherited my recently deceased father's 1992 Ranger with the 2.3 liter engine. He was a Ford Mechanic but got to ill to worry about fixing the Ranger. So, let me begin, the engine dies randomly, (at idle or in gear driving doesn't matter what gear or speed), turning key to off and then to on will allow vehicle to restart every time. No "Check Engine" light has ever lit, I do have an "Antilock" light that comes and goes. The engine codes I keep getting are: 10, 218 and 222.
Code 10 is a computer check code,
Code 218 is "Loss of Ignition Diagnostic Monitor (IDM) signal/left side, and
Code 222 is "Distributorless Ignition System - Loss of right side ignition diagnostic monitor (IDM) signal.
These codes were from my Innova reader. I have read where other similar problems were fixed with a new Crankshaft Position Sensor, replaced mine, no change. Another symptom I just noticed is my temp gauge stays near the cool end when it should be higher.

I have a 67 chevelle and it runs great but after driving it a while it starts backfiring. I think it is when it gets hot, is this possible and why is it running hot. It is a straight 6. 3 on a tree. Smaller engine like a 250 or something. Original engine and everything. I have had the car since I was 16, now I am 40. Somehow I still don't know how to fix it.

My 77 Nova sedan has been leaking motor oil from where the motor and transmission meet, around the oil pan region. I have been told it is the rear main seal but I would like to get some more opinions as to what might be the cause to the leak.

i have a 2005 chevy malibu classic. a few months ago it started sputtering when we would try to crank it and would take several tries before it would run, then it stopped. So far we have replaced the fuel filter, fuel pump, fuel pressure regulator, idle air control valve and crankshaft sensor, and it still wont stay running when you try to give it the gas, it dies....

I have the classic ticking sound on acceleration. I had a muffler shop check it out and the tech said he thinks the passenger side exhaust manifold has a leak. I have already replaced the whole manifold and cat on the drivers side. Could it be just the gasket? The ticking is coming from the top near the engine and not the cat. Is it a pain to replace the gasket?

I've had cars that will 'ding' if you try to lock the door while the lights are on, key is in the ignition, etc so I'm familiar with the sound. My 98 'dings' at me when I try to lock the door by using the button on the door. I can't find any reason behind it, no lights on, keys out, etc.

I have a 2013 LS in which I leave my iPod plugged in all the time. It usually plays perfectly. However, it frequently loses connection for no apparent reason and the audio shuts off. When I turn the audio back on the iPod is not shown on the menu. I have to dig it out of the console and remove and reinsert the plug. The iPod then shows up on the menu and all is well for a while.

I drive an 05 Chevy Classic (that's an '04 Malibu made in '05), and it's never given me problems (though I've only had it about 2 years). This morning, I can't get it going. The engine turns over when I turn the key (though some of the time it takes several moments), but then as soon as I let go of the key, the engine dies. I tried giving it gas, but this doesn't seem to make a difference. After a couple of tries I noticed that the dashboard lights weren't coming on. They usually all light up while the starter runs, and I can at least get them to light most of the time when the key is turned to "on". None of this works. The power windows will open and close when I have the key turned to on, so the electrical system works somewhat.

I went to drive my 1970 Nova today and after driving it for about 15 seconds it seemed to stick in second gear. I cannot get it to go into neutral to be able to put it into any other gear including reverse. The shifter is on the floor. I have no clue what is going on- If it's something with the linkage between the shifter and the transmission or something with the clutch. It has never acted this way before and gave no indication that a problem was on the horizon.
