I've just started pulling a scarifier through some heavy clay soil in the South West of Australia with my 190XT series III that I bought recently. It seems to be running a bit hot but I'm not sure because the temperature guage doesn't work. I've had the radiator reconditioned, its full of coolant and Ive changed the oil and all filters.

I'm noticing that it is running quite warm - even the iron centre (steering) console is quite hot to the touch. Is this normal? The tractor is working pretty hard at about 2000 rpm.

Ambient temperature is about 18 degrees celsius, its the middle of winter here.

Would appreciate advice from any current/former 190XT owners :)

Maybe I'm just worrying about nothing, its just a bit concerning not having a temp guage. The crop should have been in weeks ago so I don't really have time to get the guage fixed.

Try cleaning the connections on the back of the gauge it won't take long and it fixed the gauge on our 7000 and turned out the thermostat wasn't opening all the time and was getting warm. Also you could put a mechanical gauge on temporarily it won't take long either.

Its a modern enough engine it ought to be running at 180 or 210 F, almost boiling, but with a 50/50 permanent antifreeze water mix and a pressure cap on the radiator it won't boil. The engine efficiency is better when its hottest. If its not boiling to make steam and blow coolant past the pressure cap, its not too hot.

Be sure the fan belt isn't slipping in worn pulleys or because of a worn fan belt.

First I'd get the gauge to work. Then see what you got. Also, check to see if the foam is there between the radiator and sheet metal. Won't cool right without it when worked hard. Also there is supposed to be a firewall of sorts behind the engine up under the hood that deflects the heat.

Thanks for all of your replies. The wiring behind the dash is like old spaghetti soup but after much scratching of my head I managed to divert power from the dashlight to the temp guage - and its working fine now.

Under load and after 1 hour of work I am half way into the green - not into the red at all. Which I assume means that everything is OK. So I'm back to driving in circles for the time being.
