tropical thermostats

[Sith]

I have a 300tdi and a guy was telling me to whack a 160 deg tropical thermostat in it before we go up north ... any truth to it ?

what the standard one?

the thermostat simply keeps the coolant in the engine at a set temp, going to a lower/higher temp than reccomended can cause issues, the only real upgrade is if there is a high flow option available from an aftermarket supplier

higher ambient temps mean that the standard thermostat is going to spend more of its time open, going to a lower temp thermostat will essentially mean that once the engine is up to operating temp, the thermostat is going to be permenantly open.....

changing thermostats wont really do anything to help, especially if the ambient temps get to a point where the cooling system is no longer capable of shedding the excess heat

Ah ok thanks ! The guy just had me a bit baffled when he was ranting about how most people never know and cook their engines pre maturely ... I didn't get a lot of what he was saying but thought I should ask people in the know ;)

It's blocked cores that cook engines,a cooler temp thermostat will only open earlier and make it overheat quicker. Pat

he'd want to be talking Fahrenheit.

thats only 71 deg c

it wont hurt anything.

what the?

The thermostat's opening temperature won't make a blind bit of difference to the capacity of the radiator to dump the heat removed from the engine by the coolant to the atmosphere. The purpose of the thermostat is to hasten warm-up and to regulate the operating temperature.

If you have an Isuzu 4BD1 you probably are aware of the necessity of having a properly operating thermostat. They perform poorly and use more fuel if running cool.
