1997 GMC C2500 Coolant

Thanks for the reply. Yes the coolant was low. I added some and then I drove it, and I couldn't see any change in the level. It runs a little over 150. There is no engine knocks or noises. When I just changed the oil, it didn't look too bad, pretty normal, black, not milky color.

So right now it isn't over heating. The outside temp has been about 30 at night and 50's to 60's during the day.

I really appreciate you help!

God bless,

I just drove it and put about 100 miles on it today. The coolant level was great, and the temp stayed 160 the whole time. I haven't seen any more coolant dripping out of the exhaust.

My question, could it be that when it warms up then it fixes the problem (but yesterday it leaked even when it was warm?)? I also just (yesterday) changed the oil and I put Lucas stop leak and oil stabilizer in. Could that have had an affect?

Thanks for your help.

God bless,

Okay, first off I am back home, so I am set (in a way). I have tasted (I know it is terrible and it has voided my warranty.) The fluid, and it tasted a little salty. I just added green coolant. The coolant that it had before was more of a clear color.

I figured out that the coolant (I am pretty sure that is what it is, but again not positive) vaporizes when the muffler is hot. When I was driving, and then would stop, it wouldn't be dripping. I got home let it sit for an hour or two, and it was dripping again. The exhaust smells somewhat like coolant.

Would a semi blow head gasket have the coolant leaking symptoms? I haven't noticed the coolant going down. I have a reservoir for the coolant, and that has appeared to stay pretty much the same. I have check the radiator itself to make sure that it is full, and it is filled to the brim.

I wonder if it is condensation. I know what condensation is on a cold morning. Today it was sixty's and dripping. Also would condensation drip that much? It is a somewhat steady drip, nothing real fast.

So I guess I am wondering if it is a failing head gasket, if the fluid is coolant. What do you think?

Thanks a lot for your help! I tried to give you a five star rating, but it would let me. It said that I didn't have enough points to give.

I really appreciate your help. I took it to my local mechanic and he said the the head gaskets were fine. Whhhewwww. Lord sure took care of me there! Thanks for the tip on the bad intake gasket. I will have it pressure tested. I also got a water pump, since the old one is going bad. I am going to replace the t-stat at the same time. I got the one that if it fails it is in the open position.

Thanks for your help. We should be good now.

God bless,

BTW, I need new bushings for my left front driver door. Can you give me a link so I can order from here, and you get credits?

Let me know.

God bless,

John

Thanks so much for the idea. Too bad you all don't sell parts. Now I am going to replace the water pump and T-stat. I think I can get those in this afternoon.

Thanks again for all of your help.

God bless,

John

Water pump and Tstat went in pretty well. Of course I took the fan and clutch assembly off with the old pump, and had to re-assemble it again to use the belt to take the fan clutch off, but that is they way things go. Otherwise everything is in and doing fine.

Thanks for your help.

God bless,

John
