Okay, I have the 87 4runner, 22re 5sp.
oversized (3 row) radiator, small 1/8" hole drilled in my t-stat, newer water pump, belts, hoses etc. runs perfect.
I recently had a shop do the r-134 conversion to my a/c. under normal driving conditions the temp stays normal with a/c on. yesterday i did some stop-and-go driving on a very hot day. my temp gauge read very hot- not overheating, but very hot. i shut off the a/c for awhile and it cooled down.
i went home checked everything and found no problems.

is there any way to make it run a little cooler? maybe put a t-stat in without a hole in it for summer and put the holy one back for winter?? electric fan??
any ideas?

thanks!
