Thread: How to tell if you have the GOOD Lower Intake Manifold gaskets.

good stuff. green is always the way to go.

u do have the car apart right? like you didnt flush the coolant and add more to drive while you wait on the gaskets?

GM seem better than the Felpros to me. I have the GM ones on my car and wouldn't use any other.

But then green and dex have a party.

And green by itself isn't so great when it comes to pitting of aluminum.

Use long life coolant and just replace it at proper intervals like you're supposed to.

I do.

At the very least something like prestone long life.

well eddie then i guess you didnt have much choice. just sucks cuz ur gonna lose quite a bit of coolant doing the gasket replace.

doesnt seem like theres much of difference with felpro and gm but i suppose thats personal preference. as long as you have the metal kind which is the 2nd design, you're in a better position.

i dont like dex cool. sh!t stinks real bad if its old. which everything does but dex seems worse. IMO it tears through gaskets much quicker. if you do a proper flush you wont mix Dex and green because that is bad. so if its just green you're good. Dex seems more designed for enviornment friendly purposes. you have a good mixture of green and water then you cant go wrong. but thats just my opinion.

Why state your opinion when you could go out and try and find facts?

I thought the green stuff was extended life already?

You can still get old school ethylene glycol. Rated for 2 years and 120 000 km or 80 000 miles.

I cant. i state that its my opinion because these are my experiences. i give my insight, you give yours, people read/do research and make a decision. i wont intentionally steer someone wrong by saying you absolutely cant use Dex but ill say IMO green is better. if you seem to KNOW Dex is better then y dont you educate us with your facts?

then you risk the chance of mixing dex and green or contaminating the system with tap water

it causes it to build up in certain spots causing sludge and some other things if someone wants to add something a little more technical
