Thermostat

[fnofjr]

Can't find thermostat for an M, all the new ones look different. Does this matter?

Things change over the years and a new thermostat WILL look different.

If you don't trust the supplier you checked with to get you one that's correct for the application get one from your CIH dealer.

Like was already posted, if not sure, get the one from IH dealer. Some put in a more conventional type and then your bypass system does not work and this is not good. Another thing, a lot of thermostat housings are eaten away and even a new thermostat will not bring engine to operating temp on light loads. I have devised a couple different methods to overcome this so temp will come up just sitting with no load on engine.

Best if you get an original style replacement; an automotive type just doesn't do the job as well. They are about $16-$20.

Should have added also that the replacement one you get in the last 30 years or so does not look like the original but it does the same job only a whole lot simpler design. Has a rather long tube that goes into the upper housing to allow bypass system to work until it opens to radiator.
