Opinion Needed: Unusual set of symptoms
#22
Thanks for the advice with transmission lines. I got an Acdelco replacement for the radiator that had the bolts built into the radiator.I'll replace the quick release fitting on the transmission line too. Might as well.
The water pump was replaced by a mechanic at around 100,000 miles. So that's good
Ughh, I'm dreading the day that these gaskets go. If they haven't already. Might have to take it to the shop for that one. I have the Haynes manual but it's pretty confusing for a layman.

I changed the gaskets myself and it was a pretty in depth job but I took my time and it got done, saving me a ton of cash.

Hey man, if you know your water pump is still good then you need to buy some radiator flush and get all that brown gunk flushed out of your cooling system before you get that new radiator hooked up. It's rust from your old water pump and your cooling system was never flushed all the way out. Please trust me when I tell you that stuff really needs to come out as best as you can get it out of there. You might need to use a couple bottles of that radiator flush. They sell the Prestone brand at Wal-Mart. Plus, since you just put a water pump on not too long ago, it will wear out prematurely with all that rust going through it. The cooling system on your Monte can be a pain to get all the air out of too. I followed the procedure in the How To Burp Your GM Car thing you were talking about earlier in the thread and it worked pretty good for me. Also, GM v6's are really bad about blowing intake gaskets. If you get 100k miles out of one without replacing intake gaskets you're doing pretty good.

Well guys good and bad news..
Everything went fine with the flushing the system and replacing the parts.
Thermostat was definitely stuck open.
Bad news... Coolant elbows are shottttt... Leaking pretty bad. and actually squirts out at high rpms.
We were revving the engine to warm it up and get the coolant flowing. Then we noticed coolant shooting out at around 3,000rpms. From this elbow. http://img109.imageshack.us/img109/2044/dscn1126v.jpg
Gonna get the Dorman aluminum elbows to replace them.

Search up top for "coolant elbows" then go to page 8 out of 10. There's a thread about 4 down called "00 3.4 coolant elbows"
I tried posting the link but it didn't work.
