Green coolant vs. Blue BMW coolant

[backtrail69]

Been using green pre mix compatable with everything stuff in all my bimmers with great results..

Green it's hazardous for your aluminun parts, Chrysler recomneded us stop using green and changed it for red/oange wich doesn't kill alu. Blue came out after red/orange wich it's sopoused to be better.

OK, I'll stick with the Blue stuff.

Thanks as always for sharing the knowledge.

I can't remember the specific make up of it but the red stuff "Dex Cool??" is NOT okay.
Eats the tank seals in the heater core, radiator, heater control valve....

Correct, it fucks shit up. Basically.

ive been running dexcool for awhile now with no problems, but the stuff sure is syrupy.

Shit I guess water is bad as replacement for cooling..

[franco90]

no just kidding shit i learn new shit every day

I like to see gen-eu-wine BMW coolant stocked in my garage.

Word.

You don't want just water, because of the boiling point issue (I think) and rust formation from impure water.

The main reason to use the blue BMW antifreeze (other than it is the good shit) is DUH!..... it just looks cool to have a blue coolant reservoir! :hitler:

i just use water cuz when i race because i don't want to have to clean up the green or blue mess that will pontentially get me booted out of the race in the misfortunate event that i bust a hole on a radiator pipe or what not, but i live in cali, so the weather is different, i guess...

how bad is it to do that...?

Running straight water will wear out your water pump bearings as they don't provide lubrication to them the way that running a mix of coolant and water does.

You generally want to run watter wetter or another corrosion resistor in straight water. Most track cars run straight water with water wetter/corrosion protection in case of a leak.

Track and street conditions are very different.

A million years ago when I raced Datsun 510s (True...I worked for BMW and raced against them in the 80's) we used a mixture of watter and ethyl alcohol. We always drained it out at the end of the day and we never expected anything to last more than several races.

Coolant/Antifreeze is necessary on the street for corrosion, lubrication and boil over protection.

I've been using the pre-mixed green stuff for a while and haven't had any problems.

Green is in the car right now (previous owner) but I have BMW ready to go, just been lazy.

I thought as long as its phosphate free it was ok.
