Thermostat question

[John Hatchett]

I don't think I have the correct thermostat installed. I think it might be too short and the bottom is not closing off the bottom orifice. How tall should the thermostat be?

It opens and closes around 180F so it seems to be functional for what it is. I just don't think it is the correct fit as my BJ41 just nudges off the low temperature end of the gauge.

Is this a new T-stat install? When did the temp start showing low?

 

[John Hatchett]

This t-stat has been in for awhile and the BJ was sitting up for awhile as well. I just started driving it again around the ranch this month and was getting annoyed that it wouldn't heat up all the way. NOt sure if I installed this t-stat earlier or the PO. Pretty sure I did when I first got this thing into Texas around 2008.

I'm guessing the bottom valve is sitting about .25 inch too high above the seat in the lower housing of the 2B engine.

@Dieseler, any leads on a thermostat for a 2B engine?

90916-03059 is listed for the BJ42 3B 81-84 which is also listed for the same year 2B

Thanks,

I got one in this past weekend and installed after flushing and fresh coolant. Seems to be working, albeit still on the low range of the gauge but I am just puttering around my property. Old t-stat was 82C and new is 88C.

The new one seems to be the same dimensions as the one I removed.

Question ... does the bottom valve rest CLOSED on the lower housing or does it close at temp?

where can I buy this therm?
