need some help....

I got a 1993 toyota 4x4 22re....

in the morning when I get about 3-4 exits down the highyway my truck starts to overheat....I can let off of the gas/put it in neutral and coast a little ways and the temp instantly drops to normal...I can then procede to work w/ no problems...someone told me my thermostat was sticking so I replaced it last weekend but I still have the problem....

any suggestions?

Thanks-

this is a newbie section, so i wont tell you to search, but here is the answer found by searching the toyota section
it is from the FAQ

Thermostat Problem

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 - http://4crawler.cruiserpages.com/4x...html#Thermostat)

“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.

no go to your dealership and buy the correct thermostat

preciate it....

I'll try to search harder next time....

The 2stage T-stat works great, I just put one in a truck I used to have. I am told you can just drill a small hole in the stock T-stat also. I haven't tried it but it's supposed to work. :D
