Hey guys, just wanting to pick your brains over this one. I've had a search through the forum and havent been able to find a similar issue, but I have found a few other answers that may help in this situation. So far Im thinking I have a thermostat issue, so let me know what you think.
Since I've owned this car the temp gauge on the dash has never sat where I would consider to be the normal position. Durning extended long runs it sits around 1/3 and it normally takes a bit of time to get there -longer than I would consider normal. Also the auto dosent shift into overdrive when cold until I've driven 1 or 2km's (read on another thread the auto wont shift into overdrive when engine is cold). When things get a little slower like in stop start traffic then the temp gauge creeps up to around a normal position of around 1/2. Cooling fans kick in where you'd normally expect them to. Once back to extended running again the temp will slowly creep back down to 1/3.
So to my thinking I have a thermostat thats possible stuck open.
Any thoughts?

All-Trac sits about 1/3 the way up on the gauge, the '91 varies from dead center to a bit high depending on how fast I'm going.

My '87 shows just slightly less than halfway ever since I can remember, and the engine warms up very quickly even in cold weather. What you describe sounds to me like the classic symptoms of a stat getting old and not working properly. Always use Toyota thermostats there is no substitute for this part.

That's exactly what you have. Replace with OEM, make sure the 'jiggle valve' is at the top when installing.

If fans are not running all the time, checking the thrermostat sounds like a good idea

Well, after driving down a long steepish hill - long enough not to use the accelerator for around 3 mins I made up my mind the thermostat needs changing. The temp gauge dropped off to nearly 0 after the run down the hill. So brought a new one from Toyota and now the temp gauge does exactly what I expect it should, comes up to just under half way very quickly and stays there. So very happy now

Dont you just love it when you start a chain of repairs. After so long with the cooling system not being at the right temp and I assume the right pressures it all goes pear shaped when put back to normal. Now the top radiator tank has sprung a leak, so a new one of those will be going in as well:lol:
