Yes another coolant question

I had my expansion tank replaced Friday and I noticed they used the green coolant. Should I worry about it or just run it until the next coolant change, which I do every year.

Grren coolant was in the car when I bought it, but I changed that out to BMW coolant back in July.

I'm thinking it will be fine for a year.

Thanks, jjp

If you are looking for people to tell you "green is fine" you are probably in the wrong place.

That doesn't mean that your car will explode or cooling system will fail due to corrosion or silicates or other reasons in one year... but generally one year turns into 2 or 3 and 50k miles later you might regret it.

If you are worried it might be worth piece of mind. Who knows what kind of green they even put in.

Yeah I know. most people here are probably saying getting it out of there. If we get a warmer day here in the northeast I'm just going to change it for piece of mind. If not I'll do it in the spring.

Thanks, jjp

I'm sure I'll get "flamed" for this, but just about every brand of coolant/antifreeze is now formulated for aluminum radiators, heater cores and plastic expansion tanks and fitting along with plastic water pump impellers. As long as the coolant is full, un-contaminated and changed at the prescribed intervals, there should be no problem(s). On all 5 of my E30s (all with over 150,000 mile son the clocks) all that was ever used was Prestone. Continue to use the same in both my E46s. A good additive for any brand coolant/antifreeze is a bottle of Water Wetter.

Re: Yes another coolant question

Are you sure its conventional green? If it is, drain it and use the lighter green one. Conventional green contains silicates and phosphates that the "universal" coolant does not have. The universal stuff kinda has a greenish tinge to it, but not as green as the other stuff. Prestone or Peak have EG formula, but most auto parts store's house brands have the same thing at a slightly cheaper price.
