I was checking my coolant level the other day for the freeze protection and was wondering if this is some type of special antifreeze. The color is blue. I have seen yellow and red but never blue. Ethylene glycol (EGW) or propylene glycol (PGW)?

Thanks

See this thread, blue looks OK (OEM) but it could be orange/yellow, but it HAS to be HOAT Zerex G-05 as per specs in book, no exchanging for cheaper fluids. HOAT is Hybrid Organic Acid Technology.

If you want a laugh, see how we did it in the old days.

Ooops, sorry got to go, my wife has just asked me to go down the store in my little gyro-copter and get some milk. I'd go in the turbine car but one of the the wings has sprang a fuel leak.
