The temp staying normal when moving would sugest to me there is an airflow problem and has something to do with the setup you have to pull air thru when not moving.
A: I assume you have a shroud around the fan and idle speed is correct.
B: If so I would think maybe your fan is definatly in need of attention.
C: If the above are fine then I have NFI

Question:
“Why does my engine temp go all the way up to the red before it comes back down to the middle of the gauge after I start it up in the morning. It only does this when the engine is cold and once it warms up it seems to operate normally. Could it be as simple as a stuck thermostat?”
Answer:
(From Roger Brown’s Web Site)
“What happens on the 22R and 22RE engine, when the coolant goes through the heater core it gets cooled off enough that when it gets dumped back in on top of the t-stat it shuts it. Therefore the temperature in the engine continues to go up. The t-stat that I have mentioned has two valves in it, one at the regular temp. and one smaller on at a cooler temp. If the cool water shuts the big one, the smaller one stays open. All this happens because of the lack of a by-pass hose, which on other systems, keeps hot coolant running on the t-stat.”
You can get the two-stage thermostat mentioned above from your local Toyota Dealer.

well, I just changed the thermostat.. it works fine and opens at the right temps.. when it gets upto 1/2, I can see it drop down to about 1/4 when driving
A stock motor with a stock cooling system, will be the most efficient you can get for your money. Toyota are not silly they had a shroud for a reason, i recommend making one, copy a stock item, or purchase one from a wrecker. Remember to haggle the a$s out of the wrecker, they like to ream HARD when n00bies are buying stuff. Fight back and pay minimum amounts.

yes you need some for both sides. make sure the amount is exactly the same on both sides or you will get death wobbles at +15kph. but if you do, you can always put a brick inside the tyres to balance it up.
The shroud makes the fan suck air through the radiator. Without a shroud the fan sucks air from the engine bay (less resistance than through the radiator).
