I use the Prestone orange stuff in my '97 Bravada. I flushed the Texaco Dex-Cool right after buying the thing and noticed lots of heavy solids that was explained to me by email as stop-leak pellets put in at the engine assembly plant...regardless, the plastic intake manifold gaskets fail whether you use the orange stuff or the green stuff. If you use composite or paper intake gaskets, I don't think you'll have any trouble....I have 138k on the original water pump and now a Felpro plastic intake gasket.

This is the first I've heard of this. Could this be why I have coolant in my oil pan on my little chevy? I parked the truck a month ago cause I didn't have time to work on it. Dreading pulling the top of the motor off.

So, it's prolly the intake and not the head gaskets?

Then it will cause problems as it gels and clogs heater cores ,radiators. If it has blown a head gasket then the problem was there to begin with . [img]/forum/images/%%GRAEMLIN_URL%%/cool.gif[/img]

I've used the stuff in my 99 Z28 since day 1 and have never had a problem. Same for my 98 Camaro and the two or three people I switched over to the orange stuff.

Like the above post, just don't mix green and orange and you'll be alright.

Yep, that looks like the stuff that came out of my little 4.3 and not long after the flush, the radiator developed a leak at the right side tank so it got a second flush. About 5 years later, I started losing coolant and found the intake manifold gasket leaking to the outside and then only after stopping the engine hot when the pressure reaches max.
The new intake gasket is a plastic Felpro so I'm hoping it's an improved piece although if it lasts 9 years like the first...well it'll get another new one with the valve job if I still own that piece.
I read a Northstar post on another site that when following the recommended maint. coolant flush, they also put in some genuine GM stop leak pellets as part of the job...

Clunk...how many miles did you have on your 4.3 before you did the rad flush?

It wasn't long after I bought it used, maybe 40k.

what kind of collector car? Any LS1 or LT1 based motor will not have intake coolant leaks, as there is no coolant running through the intake. But as with ninja, we always replace orange with orange and green with green at my shop, some motors building as much as 900-1000RWHP. And either coolant cools just fine.
