adding coolant question

[fasternu]

Both my Explorer and my wife's Grand Cherokee are a little low on coolant. They both have the pink stuff in it. My question is I have a new gallon of the old Green/yellow coolant. Can they be mixed or should I just get rid of the green/yellow stuff and buy the pink stuff? Thanks in advance

pink stuff is 5 year anti freeze, green stuff is 1 year anti freeze. Yeah I know nobody changes their anti freeze but that is what is recommended. No don't mix the two.

You don't want to mix them!

They should be flushed and have green added. They shouldnt have pink in them anyway.

Depends on what year.

For example

03 explorer could have green or orange.

03 grand cherokee would have "HOAT" (Hybrid Organic Additive Technology)

both are 05s and came from the factory with pink.

Ford has never used Pink coolant, they have used orange coolant in the 99-02 Mercury Cougars, and in the Electric Ford Rangers only. Besides that they have used Gold, or Green. Gold being the extended life, but Ford has never used Pink coolant!
