Yup, and given the cost of the red stuff vs. the green stuff (the red is more) even if it was compatible with older vehicles it wouldn't be economical to use. The idea behind it is that is is good for 5 years instead of the green's 3 year lifespan. But I flush my coolant on an anual basis so the longer lifespan doesn't mean anything to me.

5yrs?
Wow i'm not even sure mine will survive for 5yrs. At the rate things are going now, by the time the 5yr mark hits i will have replaced everything on my truck and thats only if i can afford it... hehe

Check the gasket between the water pump and the timing cover. Mine is leaking (83). I put some stop leak in it and is is temporarily sealed, but will have to fix it soon...

yeah i already fixed the prob... turned out the water pump seal was bad so i replaced the water pump and everythings all good now. Well as far as the coolant leak is concerned

Only after I conducted tests on my engine's system have I found that the "orange" coolant appears better than then the ethyl-glycol coolant. I found that even if you want to replace the coolant annually; the orange coolant produced less harmful impurities than the ethyl mix. There may not be any need to change your coolant, but the worst problem with coolant-heating systems is the deterioration of the aluminum material in the coolant path. This includes the heat exchanger in the cabin, and the tubing slots in the radiator. After one year of operation with the "orange" coolant is showed minimal deterioration.
If you are satisfied withe the ethyl-glycol mix there is no reason that you should "have-to" change over, but be aware that there is a difference in performance. I am going to stay with the orange mix in my system, and I include two bottles of pre mix in the back for emergencies.
