Toyota question - 22r engine

I just bought a 4x4 4-Runner with a 22r engine. It is a 1984.

Runs great. It has a Sunpro temp gauge installed in it, and the temperature is running around 220. That seems a little on the "warm" side to me.

Keep in mind though this is in Houston, TX where the outside temp was around 100 degrees, and freeway driving.

Does this sound too hot? Is there anything I can do to cool it down a little bit? I don't know what to check.

I have a 80 yota and my temp is around 170 to 180 here in San Antonio. 220 seems kind of high. check out 4x4wire.com they have all the yota answers for you. You do need to sign up and it is free.
As for checking? check if it still has the fan shroud around the fan by the radiator.
check the antifreeze/water in the rad. Also when checking the water...turn on the heater so that the fluid/air bubbles will get flushed thru the system.
Last would be the thermostat. AutoZone sales them.. For my truck they had two different ones...one thermostat opened at 160....the one i bought and the other at 180.
Being that you just picked it up....getting it flushed would be a great idea some people have had the heater core clogged causing the temp to flux.
check the temp after that and then maybe change out the thermostat.
Good Luck,
Mike

Thanks man. I'm getting the rad flushed tomorrow and oil changed. It's a crusty old 4-Runna, but it fires up and purrs like a kitten with ease. I'll probably also buy that 160* thermostat tomorrow just to have it handy.

I'm talking to the 4x4wire guys now also.

I'm hoping the flush/fill will solve the temp issues because I have to go on a 4-hour drive to the deer lease with it tomorrow evening. Driving at night should help keep it cooler also I hope.
