Old style thermostat replacement

G'day all,

has anyone ever removed an older style thermostat similar to this one below, and replaced it with a more modern type simply for ease of operation, and a guarantee of it working more effectively?

if so, is it a safe bet, and are there any considerations i should make prior too?

Cheers!!

I have used the later style thermostats in my ww 2 jeep and series 1 LandRovers they work just as good. And the rivet counters can't even tell.

On some of the older set ups (Leyland & AEC for example) the thermostat also opened a bypass as it closed the main flow to the radiator and a modern one can't do that. Yours looks like a simple type which is suited to substitution by a modern.

Comtruck, sorry to go slightly off topic here, but where on earth is the thermostat located on this engine? Is it the bit that sticks out the top of the waterpump where the radiator hose connects to? And also, can you post on here if you find a suitable replacement that works?

I'm interested in what you come up with also.
What would be a good starting point for the temp rating of the thermostat, for a petrol or diesel engine? Any difference between the two?

Is this the bypass you speak of?



If this is the bypass, both my buses have been blanked off, and are running no thermostat. Would running no thermostat cause any problems on a diesel?

with NO thermostat the motor will run to cool ... which will cause excessive exh smoke,unburnt fuel..carboning of the internals.. lower oil life ..etc

All motors, regardless of whether they are petrol or diesel, should operate at between 82

the thermostat housing sits directly on top of the engine. if you have a look at the pic (above), the spring looking part sits inside the head. ill go and get a pic of it now attached to the head.....

Hope this helps!

Thanks. The head on mine is a bit different, but I should have a rough idea of where it is.
