Attention: TDR Forum Junkies 
I am working on my friends 1992 first gen. I replaced the leaking oil cooler and did 4 complete cooling system flushes finishing the last flush with the Fleetguard Restore flush. All the flushing was done with the old parts still in place except, of course, the leaking oil cooler. I have replaced the radiator, all hoses, water pump and thermostat.
So here is the question. Can we now use the new OAT type long life coolant in this engine?
