so my woes begin...

..hard to swallow
Last night driving the ty home from work and gave it a short blast passing in traffic. It's only a 7 mile trip and when I got close to home I began to smell coolant. After I put it in park coolant started smoking through the defrost vents into the car :banghead: I haven't driven it since. It was dark when I got home so I did not mess around with it but I'm going to check it out today. Hoping it's not a head gasket but not sure what else it could be. Any ideas to point me in the right direction? Thanks

coolant coming thru the defrosters is most likely a blown heater core. check if there is coolant on the passanger side floor also , then that would be the problem.

Thanks, I'll check that. There didn't appear to be any coolant in the oil and didn't see any white smoke out of the exhaust. The guy before me said he put a new heater core on fairly recently. I'll check the lines and core itself and see if I see any coolant leaking out

Do yourself a favor and buy a GM heater core when you replace it. I did mine 7 years ago and have not had a problem since. The aftermarket heater cores are junk!

Rockauto has this one ACDELCO Part # 1563330 {#19131990}
CORE,HTR w/HVY DUTY HTR(C42) for $42.89. That's the one I want right?

Anybody live around the DC area that could lend a hand? I've read up on these changes and I know they aren't supposed to be that difficult but I figure if somebody has done it before it would save time and headaches.

That's the one. Price has not changed much in the last 7 years.

Biggest thing about doing the heater core is take your time. If you rush it you will break something and end up with more of a headache than you need.

Re: so my woes begin...

Update - I just linked the heater lines together and have no more coolant issues. The main thing now is that the truck is very hesitant in the morning startup. The idle is rough and it when I give it gas it doesnt really want to move...after gentle coaxing it will warm up and drive fine. Temps look good...oil is at proper level and not milky. I did notice that oil pressure looks weak on the stock gauge but I know thats a pretty worthless gauge. It didn't do this before the heater core issue. The shop that did the last core replacement and engine rebuild said they'll look at it when they get a chance. Anything I want them to check in particular? Thanks!
