Overheating / High Idle after day of wheeling
Took my 4Runner out for the first time today after finally getting the shocks bolted on and 9 months of work bringing her to her current form.
Wheeled all day with the engine running for around 6 hours total and the temp was fine all day - driving to the trail (50 miles) and about 50 miles of trails. On the way home after about 30 miles I notice the temp gauge is way high - touching the red. So I crank on the heater and drop the RPMs a little and it seems to go down a little. But when I get off of the freeway onto City Streets and stop at a red light it goes into the red again and my RPMs at idle in Neutral at the light are around 1900 rpm.
As part of my build I did replace the alternator and drained all of the coolant. Does what I describe sound like I potentially have air in the system? Weird thing of course being that it ran fine without overheating for 6 hours of wheeling!

Ahh yes - I did put a bottle of fuel injector cleaner through it a while ago, as it had been sitting for a year. Plus I seafoamed her a few weeks ago - but none in the fuel. Just used the Brake Booster line and sucked about half a bottle of Seafoam through.

I do have some cracks along the top of the radiator, looks like the JB Weld didn't do the job. Just ordered a new radiator from Radiatorbarn, so once that arrives I'll have to drain the system again anyway. Will make sure to burp this time after re-filling tho.
