Hi guys -- I ordered a new 180-degree thermostat from Atlantic British, and when it arrived I looked down the throat of it and it's marked "198F" on the internals (see picture).

I called AB and they had me check the part number on the box it came in and confirmed that I did in fact have the correct part.

So my question is, do they have this wrong or does the low-temp thermostat indeed have a "198F" marking on the inside? The brand on the housing says 'MotoRad' and it had a green dot.

 

Send it back. The product in the box is not what you wanted. This is a known issue and has been happening for a few years.

 

Yep send that back!! AB should be ashamed of themselves for selling a 92C thermostat!!! Heck even Auto Zone sells a true 180F Motorad thermostat for 33.00...

 

Do the inline mod, everything else is asking for trouble.

 

what is the inline mod?

 

It's listed in the stickes at the top of the Disco 2 forum.

 

Ok I think i found it thanks!

 

I bought a motorad "180 degree" from AutoZone for $33 and it looked exactly like that. Spoiler alert: It wasn't a 180 degree t-stat. Glad I only wasted $33 on the thing. Ended up doing Extinct's aforementioned inline mod, its 100% the way to go.

 

The last few I got at auto zone were 180F units, but I verified em before leaving the store.

 

How did you verify the operation of the thermostats in the store, without putting them in a pot of water and heating it to see the temperature at which the thermostats opened?
