coolant help?
 

Just did a coolant drain and replace water pump and thermostat.
I got about 5 gallons of coolant out but it is a yellow color. It looks clean but I noticed Porsche OEM is pink. I am worried about mixing these 2 since you never get 100% of all the old coolant out.

Should I be worried?

Thanks

No. But if you are. You could fill it back up with water (some would say only use distilled) run it up to temp and drain it back out. Then put the new stuff in.

Good reason below.

Will do one vacuum in of pure distilled water and flush just to be sure.
