#18 of 47 Coolant Leak: Unknown Part Name For Leaking Coolant Pipe
Nov 10, 2008 (4:20 pm)
I have a 1998 Chevy S-10 with a 2.2L Engine. There is a steel pipe on the top of the engine towards the drivers side. It is mounted down with one bolt on the back side and held into the thermostat housing on the front. It also contains the Coolant Temperature Sensor right before the thermostat housing. And on the back side of the pipe there is a rubber hose that has engine labeled on it. This steel pipe is leaking and i need to buy a new one to replace it. What exactly is the name for this pipe so the guys at the auto parts store can look it up for me. Any help is greatly appreciated.

This sounds identical to the problems I have had with my 2000 s10. The dexcool stuff is terrible and GM recently settled a class action lawsuit giving most truck owners 50 to 300 hundred for repairs. Did you fix your intake leak or?? Just curious as I now have one as well.

That leak happens now and then, not yet on my 99, but only 55K. Just buy a new pipe and housing assy, it should be available after market.

I flushed the cooling system and replaced thermostate on my 2002 GMC Sonoma with79,000 miles on it.
I've had nothing but probems after that. Service engine light came on, did diagnostic - water temp below engine temp. Replaced temprature sending unit. Same thing? I have to drive 10 miles before engine reaches operating temp?

After RR radiator and water pump on GMC Sonoma 4.3L coolant is leaking to oil pan. Truck is not smoking and compression is good on each cylinder. What could be the problem?

I change the thermostate and it is working fine so far. I'll have to wait for cooler weather for a real test. It seems to work better when the outside temp is higher than +40 degrees. Fuel mileage is up to thank goodness.

4.3L 's have an issue with intake manifold's leaking. I had the same problem on my 94 GMC Safari. Changing the gasket took care of the problem!
