o.k i am a virgin here at conquest cars i need a professional answer from all you pros.......... my 1989 runs alittle on the hot side do i install a 160 degree thermastat? i am about to add clr to my radiator and try and remove as much calcium lime and rust as possible i was going to add it then fill the rest with water and run it on 3000 rpm's for about 3 minutes then the other 2 minutes normal,then shut it off and drain it all,then do a regular radiator flush then add hyper coolent which is suppose to help keep the temperture down by 20 degrees and then finally add 50/50 antifreeze............. anybody have any cheaper ideas then this to help bring the temperture down while running? i already added an extra radiator fan that i swich on at red lights and stopped traffic........
