my windsor is running at around 100 what could be causing this , had new water pump installed running full coolant got 82deg thermostat in it but its running too hot for my likeing
is the coolant boiling though? Like when you pull up can you hear a "blurp blurp blurping sound?
Perhaps install thermofans? They nominally come on at 92 celcius i believe? Toyota single wire switches make it a piece of cake to wire them up. i have a drawn diagram of how to hook them up also.
I'd run a 60deg thermostat. If you have thermofans make them run all the time eg don't use a thermo switch. Also what pressure cap are you using, as the greater the pressure will raise your boiling point. Another trick i've done is plumb the rear water jackets on the intake manifold and run twin 5/8 hoses back to the radiator or the top hose. This mod alone dropped my temp by 15 degF.

Like 302_Supra said, is the coolant actually boiling? As water gets pressurised (like in a cooling system) the boiling point goes up. According to my car's OBD, the coolant sits at about 98 degrees, and the needle sits in the dead middle of the gauge.
Also, does it always sit on the same temperature, or does it drop down a lot in some situations and overheat in other situations?
TD302 - Remember if the car is too cold it won't run properly, 60deg would be too cold, and if it has EFI or automatic choke, the car will constantly run rich.

Aaron_EF8- Remember if a thermostat opens at a certain temp the running temp is approx 20 deg higher. So a 60deg stat will end up at approx 80-90degC (176.0098-194.0108degF). He didn't state what year engine it is so if ws an older Windsor then 170-180degF would be perfect and a newer one would run a little higher. borgiewindsor- Have a look at the bottom radiator hose when it's running at temp and see if the hose is sucked in. It could be just air in the system.
Hope this helps. Cheers Brett

82"c is what my 302 thermostat is for. And it says on the packet to suit ford v8 and 6's.
Thermo switch from toyota makes the fans come on at 92"c. Perfect for everyday use.
Running too cold is as bad or worse as running hot. the oil doesnt get hot, and doesnt lubricate properly, promoting excessive wear and tear.
And the toyota switch is what is going to be controlling my thermos on the 302 supra. itll be connected with the two relays up to the battery, therefore coming on whever the water reaches the 92'c. Car running or not. Its a great thing for turbo motors especially to prevent heatsoak.
the same setup is used on my ma70 3.0L supra. These are notorious for Overheating and blowing head gaskets, and a simple 14" and 10" fans keep the thing cool as a cucumber on some home-made brackets i simply welded up and bolted to the stock radiator. Its been going for 9 months like this, and it works a hell of a lot better than the old clutch fan. even in 45' dubbo heat, it didnt go above 1/2 way on the gauge.
