My overheated 60- I need a radiator, suggestions? I've been drivin' my 'new to me' 1987 FJ60 back and forth to work, and some short trips on the side for about three months now. Never really had the temp gauge move past 1/3. Yesterday the wifey and I decide to try an extended road trip in it. 4 hours- 250 miles or so... Anyway, 20 miles into the trip the temp starts climbing. I turned off at the nearest exit and started back home.. and it kept climbing. I had to open the windows and blast the heat to keep it from pegging in the red. Slowing down actually made the problem worse. So I kept it at 50 mph and crossed my fingers. The PO odviously neglected the truck. This is just one more sign. The coolant is green- and who knows if he flushed before he filled, probobly not. So my plan of attack is this: flush and fill with toyota red, check the thermostat and fan clutch. Or should I just bite the bullet and buy a new rad? Is there a good chemical I can add to a mostly water solution to really clean out those coolant passages? I could flush the green out, fill back with water and something like 10N NaOH (super basic but might eat the hoses?) It was maddening to have to turn around on the first big test of this truck. Good news- got the new tranny clutch installed last week. I had no idea HOW much the old one was slipping until the new one went in. I find myself driving too fast now, because I don't have to be careful with the gas pedal.
