Check water pump; may have worn bearing; the revolutions may not be fast enough to circulate water fast enough.

I have a 1988 chevy s10 4 cylinder. Its over heating off and on for the last week or 2. I just replaced the thermostat and flushed my radiator but its still overheating

Drive the vehicle until operating temp. Turn vehicle off and CAREFULLY put hand between engine and radiator. If you feel any cool spots on your hand on the radiator side, you have blockage and are only using a fraction of the radiator to cool with. This is most likely the issue. But here is a list of what I would do first. Drain fluid. Remove thermostat. Install thermostat housing without thermostat. Run a flush through engine following instructions for deep cleaning. Drain . remove hoses. Run water through block. Make sure water can pass through. Replace thermostat. Run hose through radiator. Replace all hoses fill it back up and check again. Also replace hoses if they are old or weak. If the problem occurs going up hills but seems OK on flat ground I would blame the radiator.

It has a bad mis and running rich dark foul smelling smoke what's wrong? 1991 chevy v6 s10

possibly a faulty injector for the miss but if you have a head/headgasket problem it would account for the exhaust. Do a compression test and radiator pressure test to eliminate that area of concern

1998 Chevy S10 heating problem

Sounds like someone put too much radiator leak **** in it or used well water and stoped up the heater core. Take the hoses off the core and try back flushing it thru the heater core. I have found this to work sometimes....good luck.

My 1991 chevy cavalier VL/RS is over heating when I drive it just 2 miles. Nothing is leaking. What could be the problem?

Sounds like the easiest solution is the thermostat. Follow the upper radiator hose to the engine. Where it's clamped on is the thermostat housing. Remove that to reveal the thermostat.

Hi;I have a chevy s10 pickup 1996 no heat the radiator and heater core has been flushed twice.Also has a new thermostat and it wooked acouple days and now back to luke warm air any ideals?Thanks Randy

It is possible you have air bubbles in the cooling system. Loosen radiator cap or resivor cap and let idle for about 15 minutes. Tighten cap and drive and see if that helps. REMEMBER TO START THIS PROCEDURE WITH A COOL MOTOR AS THINGS WILL BE QUITE DANGEROUS DUE TO COOLING SYSTEM PRESSURE WHEN HOT.

Bent A-Arm on a 1991 Chevy S10$???

I would guess $500 - $1500 to do this job depending on how much damage was done when the arm was bent.

"SMALL OIL AND TRANSMISSION LEAK AND THE RADIATOR LEAKS OUT SLOWLY." -- the radiator leak could get bad enough to require repair.

I think $400 obo is an okay price, can't get much lower for a vehicle that will get you to the store and back.
