Lehman 120 Thermostat Replacement
Okay, I searched the forum before posting this. I need to replace the the temp senders which are difficult (near impossible, I think) to remove without the expansion tank removed. I would replace the thermostats while I have them removed but, despite being a pretty good mechanic, I cannot figure out how to remove the tanks. I have seen posts stating that doing so, to replace the thermostats is easy, but I just don't see it. There is a flange on the bottom of the tanks with studs and nuts. Remove at this point? How? Doesn't look like there is enough clearance to get an open end wrench in there. Help!!
