got this 4 cylinder from my father in law who had coolant service done at Goodyear in 4/08. they put in green coolant, not certain what type. Have read that pink or red is better in Toyota's and wonder if I should switch it out and if there are posts from others who have done this model. (I've switched out coolant before on volvos, so know the basic process of rinsing with distilled.)

 

your lucky you got something from you father in law... is there any available?
