#3795 of 4400 Leak by fantascp
Feb 03, 2004 (1:02 pm)
theiceman: It may or may not be the same problem with leaking gaskets but Gm I think separated it into 2 separate issues.- First : by only allowing for vehicles from 2000 on out and by fixing/changing fastners,adding sealant etc- not actually changing the upper/lower manifold gaskets, etc for vehicles prior to 2000- GM is still in denial that there is anything wrong.I did not buy the car new and only took out an extra 6 month warranty back in 2002- so it looks like i'm biting the bullet on this one but its still better than not having it done and then having the coolant ruin your engine and really have to pay big bucks as some less fortunate owners then I have had happen to them already.
I know there are class action suits against GM on this but its really a shame that GM still denies they designed this wrong and should make amends.
Ken: I had the same service recall done on my wife's 2003 Grand Prix GT.- I could be wrong here but I do not believe that they completely drained/replaced the entire coolant system- I think they just put in different fastners, added a radiator sealant and re-added any fluids that were low.
Ken, remember my white 2000 Bonneville SE I had,
now that I think about it, I was adding a little bit of coolant on occasion but never worried about it
as it had only around 35,000/40,000 miles on it
when we traded it in for the Grand Prix.
There probably was a leak on it but I never gave it a second thought at the time.
Evandro: You are right- GM is treating this as two separate issues. 2000 and newer for the voluntary recall etc and prior to 2000- no help for anything.
Imidazo197: I've heard both pro and con for changing the coolant from Dex-cool back to the Green. A former Service Manager at a Pontiac Dealership told me once that Dex-cool was bad and caused clogs/corrosion etc.and not to wait the 5years or 150,000 miles to have the system flushed etc.
I think I also read somewhere that its almost impossible to make sure that all of the Dex-cool is out before you switch and because if it isn't it can contaminate the regular green anti-freeze as they don't/can't mix. I need help guy's/girls on verifying if this is true or not- I really don't know for sure.
I'm not going to change mine back to Green. I could be wrong here but I have not had any overheating problems/radiator problems
etc because of the Dex-cool so when the job is done this Thursday I'm having them replace with the Dex-cool.

FWIW, I used a permanent marker to... mark the coolant level on the expansion tank. As I park the Bonneville always at the same side of the garage (the water heater robs space from the other side), it's easy to check if there's been any change in the coolant level every Saturday morning.17000mls after a new intake manifold, the level has been the same for about 5000mls since the recall.

Michael - I just took another look at your site after the suggestion from Ice and really enjoyed the link to the 1958 Bonneville - arguably one of the most attractive GMs ever produced. Also took a gander at the stats and demographics for Bonneville owners - no wonder I feel so much at home in my car! lolSure do hope to be heading your way next month. The temps have moderated from the deep freeze but it's a lonnnnnnnngg time till spring here and more dreaded 'wintry mix' is headed our way tomorrow!

Yup, headed here too. From the States IIRC. As I said before, Ken, bad weather always comes from somewhere else... >

#3802 of 4400 Evandro-Upper Intake Manifold Leak. by fantascp
Feb 05, 2004 (6:18 pm)
Going to take your idea on marking the recovery tank!Just got the car back this afternoon- Total Cost $492.17
Upper and lower intake manifold gaskets/replace anti-freeze/ oil/filter/water temp switch and 5 hours of labor! NO COOLANT CONTAMINATION!
Upper manifold gasket was the problem area.- no sludge/gunk/ coolant in engine compartment.
Engine clean and running strong!

Our Bonneville is going to get it's first exposure to Fla sun in March! We're planning to drive to Naples for a week's vacation mid month. My MIL has agreed to stay with the kids so this is an 'adults only' vacation! WooHoo!!!Turns out all the cheap air fares are long gone for that week so we'll do the 1700 mile roadtrip which is fine with me. I may even let my wife drive a while - perhaps even more than the 100 miles she drove on the same trip last April!
