Engine/Transmission (1998.5 - 2002) Fleetguard Antifreeze question

[dblake]

Does anyone know the difference between Fleetguard antifreezes? The last time I changed mine I got the fleetguard 50/50 pre-mix ethylene glycol part #CC2825(blue stuff). This time they sold me the 50/50 pre-mix ethylene glycol part #CC36077(pink stuff) labeled OAT. I believe the pink stuff lasts longer than the blue stuff? Thanks.

Look it up on the internet. I'm sure it'll tell you everything you want to know and then tell us.

The HOAT coolant is required on the later model trucks. My '06 and now '08 require it. I don't know if all HPCR engines require it. The earlier 24 valves did not require that mixture.

Do a search of my posts and a while back I posted a really nice chart from Pen-Ray that showed them all.

I am using Seth's cell phone right now, otherwise I would do it for you... .
