Awesome. Thank you. Replacing thermostat on a D12B and looks like compressor has to come off or at least get moved a fuzz to get thermostat...
Is there an o ring or gasket between the compressor and front cover.
ok so I just bought a 2000 Volvo wg64 tandem dump with a d12, put 400 miles on it just fine. Went to start it the other day and would not start....
