Hello all, new member to this forum. I have a question that probably has been asked alot but nevertheless I will ask away. My s-10 extreme has been slowly losing coolant. I have found myself at least topping it off about twice a week. Now on to the bewildering part, I have checked the oil, there is no signs of it being murky, cloudy, etc. No signs of leaking from the intake manifold or the radiator cap.

So, at this moment would I lean toward the intake manifold as a prime suspect or possibly focus my attention on cylinder heads or head gaskets?

Any help would be greatly apprectiated. I've had two s-10's in my days and BOTH has the same exact problem.

 

I'm saying its the intake manifold gasket. Its the most common problem for the 4.3l engine and the cause for most cases of coolant loss, but just to make sure, watche the exhaust fro smoke and check all the coolant hoses to make sure they are not leaking.

 

The intake on mine was so bad it leaked out of the transmission dust cover. Have the Radiator presure tested and the leak in the gasket will show up..
