I took the 4runner into my shop today to do some exhaust work. I pulled the cat out and welded in a 2" piece of tubing in its place. Again, not the issue. Still runs warm at idle.
I am beginning to think that the radiator may not have been as new as the PO told me it was. So, will a 3.0 radiator work in its place??? Meaning will it bolt in, or do I need to fab some brackets for it?
Also, this is NOT the dual thermostat issue. I am well aware of the fact that the temp will go up high when cold. Its because the heater core throws out on the thermostat, so until it gets to operating temp the thermostat won't open. This is a constant issue. Not just at start up.
