I just got this 98 Tahoe the other week. Well the other night with the air on the check guages light came on and I looked at all the guages and the temp. guage was reading very hot like almost toped out. So I pull over to autozone let it cool a while and look at the resovor(sp) tank and it was flat out of coolent. So I bought that 50/50 mix coolent thats part water part coolent thats ment for dex-cool. The truck ran cool for a day or two and then it did it again. Same thing flat out of coolent in the reserve tank. Bought another jug and filled it. Now again its out. There are no leaks that I see at all. Ive put pices of cardboard under it at night after driving and nothing. What can be causing this and what should I do about it?
