After a complete rebuild and transplant of a 1 HZ into my 62, I am running into cooling issues. After transplant, it took me a good half year to rewire (I travel a lot and gone good portions of the year), and finally this summer have been able to drive. I have a Derrale high CFM dual fan, Painless dual fan control and OEM 62 radiator (8 years old) but I am not happy when I make the drive across a couple of passes around me. Temp in cylinder head stays between about 180-188 through most driving but on the passes gets up to 200, even to 210 once before I pulled over to help cool down.
I loved that my 3FE barely ever moved the stock dial, but I did not have a aftermarket temp gauge at the time.
About ready to pull out electric fans, build a shroud and go with mechanical fan. As I plan for a turbo in somewhat near future so I am wondering if the FJ62 radiator is the right one for the job and should I replace it before I go through making a shroud.
Thermostat is 4000miles old, from Toyota, coolant is all new.
Thoughts?
