Hello folks, I have a VN S1 V6 motor, thermostat is at rear, in a 4wd. I just tried to change the thermostat, got it all apart eventually, put it back together with a Dayco DT22A (its an 82C thermostat, but the 22B is still 44mm) thermostat, the flange is full width if the housing 44mm. I also used a new Dayco O ring too. Thing is the alloy thermostat housing has a recess machined in it, to take the thermostat I assume, its maybe 40mm (39.??) .
The thing leaked once the stat opened up. When I bolt the housing down with tstat in, the housing will not sit flush on the inlet manifold on the opposite side to the bolt. The gap is probably pretty close to the thickness of the thermostat flange but the single bolt on one side pulls that side down, and the other up.
Am I using the wrong thermostat despite it being the part listed for it? I cant find a part number with a 40ish mm flange. The housing seems OK... manifold seemed fine where the housing drops in too. The leak is noticeable... I could see coolant coming from under the housing and pretty much all the way around beteeen housing and inlet manifold. I thought it was the hose at first then I saw it flowing from under the housing??
Cheers, Gary
