I have a 2001 S10. For a few years now, it has been losing coolant. I
just added a full gallon to the overflow container. I have done that
before, maybe three times now.

I see no evidence of leakage under the truck. Performance seems just
fine. I am wondering....could I have head gasket leakage? Should I
fix it? The truck has 90K miles on it, and has had zero repairs. Uses
no oil.

Thanks

Hi,
If there is no visible leak, coolant can evaporate, or burn.
1. Is rad cap good?
2. Have you cooling system presssure tested?
3. Did you put in dye to detect gasket leak?
4. Is there sweet smell from exhaust?
5. rad hoses, clamps in good order?
6. When is the last time you flushed the cooling system?
7. Is the coolant temp. higher than normal range?
