Coolant Leak, No Overheating - Possibilites?
Greetings:
I have a 1996 Chevy G10. It has a minor coolant leak. The most obvious indicator of the leak was the distinct "sweet" odor. It is not losing coolant at rapid rate, nor has it overheated on me. I have spotted small, bright orange puddles or drips occasionally but am struggling to pinpoint their location. The leaks are not near the radiator, but further back toward the engine block. I crawled under the van and was still unable to pinpoint the location, but it does not appear to be a hose. At least one mechanic suggested it is the intake manifold gasket leaking. However, I thought this would likely cause overheating or very noticeable driveability problems. The van does run a little rough at times, but I am pretty sure it needs a tune-up, so that could easily be the reason. The van does make a hissing noise when I let off the accelerator though.
Can the intake gasket's be leaking without causing the van to overheat? What else might cause a leak without overheating?
Thanks.

Weep hole on the pulley shaft on the water pump? Get in there with a light to see. Could need a new pump. Also could be a frost plug leaking. Check along the sides by the spark plugs. If its coming from the hole by the rear seal, then it could be a frost plug back of the block behind the flywheel......dumb place for one...lol.
