Question about 1989 Chevrolet S-10 Blazer

1 Answer

1989 Chevy S10 Blazer 4.3L V6 Automatic: Massive coolant leak occurred after letting truck sit for about 30 minutes after running it for around 1 hour. Coolant steadily flowed from what appears to be on top of the oil pan. I was forced to run the truck for about 10 minutes and when I stopped I checked and more fluid was pouring out from the same location. I could not see any burst horses and any fluid that was put in would pour out around 5-10 seconds after it was put in the radiator fill cap. What could be some possible areas it is leaking/fixes? Thanks very much.

Check the bottom side of the water pump for wetness, as well as the lower radiator hose. The water pump if leaking, will run the coolant down the front of the motor,and can appear to be coming from the top of the oil pan. It is nearly impossible for the top of the oil pan to leak coolant.

Do this

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.

My brother had a similar problem with his, it would start just fine but what had occurred
was a clogged catalytic converter. You could disconnect the converter to test this.

I HAVE ANITFREEZE LEAKS FROM MY 2000 CHEVY S10 BLAZER. IT'S HARD TO TELL BUT THE LEAK SEEMS TO BE COMING FROM UNDER THE MOTOR RATHER THAN FROM THE RADIATOR OR ANY HOSE I CAN SEE.


a common V6 failure is the intake manifold gasket. coolant will usually leak behind the water pump on the drivers side, however it can leak at other locations on the intake manifold gasket.

coolant leaks from other areas include the heater core, hoses, expansion plugs, trans cooler, and coolant overflow tank.

You may have a bad idle air control valve, I would also check for a vacuum leak, from a vacuum hose or a broken vacuum tee.
