Thread: 4BD1T Running Temperature

Hi
So if mine runs around 65-75 mostly to 70 does mean i need a new thermostat.

I would say it it sticking open - yes try a new thermostat

max op temp is set by the coolant and then the quality of the cooling system...


providing your coolant will handle it for prolonged periods you can run up to about 114 degrees at about that point you are right on the limit of the expansion tank caps pressure limit and you will start steaming, once your steaming your making more heat than the cooling system is dissipating, thats when bad things happen.

Id goto about 95 degrees happily then start nursing till about 100 from 100-105 it would be getting babied just enough for me to get it pulled over safely and take additional cooling aids (up to and including firing a CO2 extinguisher at the radiator with the engine running from about 3 feet away)

So, following this thread and thought I'd better check why my temp gauge isn't gauging anything. I thought it'd just be a loose connection.

Turns out it is, the spade on the back of the temperature probe isn't.

So what bit do I buy?

Buy a VDO guage and sender. Then you will actually have degrees instead of coloured bars

agreed the vdo ones are good BUT it pays to check them in a pot of boiling water or by whacking a thermometer in the thrmostat filler plug while you run it up to confrim it isnt reading low.
