1986.5 Supra MKIII

[SLED DRIVER]

Hello,I know about the bottle/overfill tank,cooling has not been a problem,car runs the middle of temp gauge or below even on really warm days crusing around town or on the highway. I have been using the Toyota red antifreeze as did the previous owner during the time he had the car. I flushed out the system really well shortly after I got the car, filled it and burped it, all A-OK so far [I know where your going with this......... the dreaded plague of all MIIIs.......... the BHG] in the time I have had it I have probably put 2,000 miles on the car,as far as the torque spec. [75 LBs.] I'll do that this weekend.I appreciate the advice. Thanks!
