I just noticed that the new 5.0 comes with red coolant. Is it Dexcool?

I recall hearing before that the Dexcool is harder on your engine that the regular green coolant. Specifically, I have heard of water pump and head gasket failures related to its use. The last thing I want in a high compression engine is coolant that compromises the head gaskets.

If this stuff is indeed Dexcool, then I think my first order of business will be a complete coolant flush. Any thoughts?

 

I think you should trust the engineers who designed the engine

 

ABSOLUTELY!!!

The guys who designed this engine know what it needs to make it live a long time.

 

I've always been a believer in keeping the factory spec myself, so long as you don't mod anything, though that said I don't use the same oil as what comes in the factory. Does the manual or anything specify what it uses by factory spec?

 

I agree...I don't think they would've designed it so that cautious owners would have to do an entire coolant flush as soon as they got the car.

 

I read on the Internet that it's freeze-proof Kool-aid. Fruit punch flavored.

 

I'm so thirsty right now, that sounds delightful.

 

Did you trust the engineers who designed the spark plugs for 3v? How about the 2v and 4v where plugs shot out of the engine? Did you trust the engineers who designed the 1999 Cobra engine? Did you trust the engineers who designed the cowl seal for the 05?

Blind faith isn't smart.

 

Haha neither is brute skepticism though Just as anything else in life, moderation in all things...including moderation.

 

True, but at this point they have more time on this engine than anyone else.


Who else you gonna call, ghost busters?

 

Dexcool is necessary for an all aluminum motor. It is silcone based causing it not to stick to the internal surfaces. I had this stuff on my old LS motors & didnt have an issue.

 

doh you beat me to it. Dexcool is best for all aluminum motors

 

My 74 Lotus was all alum. Plain ol green prestone worked fine.

 

I'll have to check the G8, no clue whats in it.

 

ah ok, well for one dexcool wasn't out is 74...think about it...and NO body said green wont work, only that dexcool was "better" for all aluminum motors.

 

Wonder if it's not Dexcool, but FL-22 coolant.

 

^^^
That's why I asked.

 

Guys, don't even think about it. Engineers did it.

 

A Wizard did it.

I say time to break out the research.

 

Yep. Engineers designed the Vega motor, too!
