2001 Chevrolet Impala Q&A
2001 Chevrolet Impala Question: coolant overflow reservoir
Personally I recommend the original one from dealer. Its an easy repair- drain coolant out then disconnect hoses from the old reservoir. There are a couple small screws holding in place is all. Install is reverse process. I like the original one so that when you refill coolant you will know its at the correct level which is very important. So your looking at 31.47 plus cost of coolant. - jason94
when car is warming up low coolant level is on message board of my Impala. I have a new radiator, and there is coolant in the overflow tank. Eventually it goes off.
