A squirrel chewed through the heater hose (maybe it drank antifreeze and died :mad: ) and I only have a non ECC replacement hose.

Well, I decided I don't care if it works like it's supposed to cuz I never use it anyway. I tested the thermal switch and it's Normally Closed. I heated it and it opened up, meaning I can just remove it and the system will work fine, it just won't wait until the water is hot before operating. I apologize if this is common knowledge. :hick:
I bypassed mine years ago due to not being able to find the heater hoses as well.
O'Reilly's sells the correct hose, if need be.
The Mark VII uses the same setup. When I had one that same hose split. I just got two non ecc hoses and cut them to match the two ecc hoses. Worked fine.
That sensor just keeps the heater from turning on before a certain engine temp is reached. I personally despise the atc setup. Its almost a deal breaker for me when I look at a car.
But yeah, just bypass it. Won't hurt anything.
On the Turbo Coupes I owned I feel same , would turn blower on high long before any real heat was available... Seems more liveable in newer models, but still something I'd just as soon not have...
When I bought my white TC for swap, two things it absolutely could not have, EATC, a hole in roof and preferably no leather... Figured I could swap seats tho if necessary...
