Solving unusual little problems with my '51 B3B is a saga for the ages. The latest has to do with the thermostat housing. On one hand, the correct housing for the '48 - '50 trucks has all the proper dimensions to fit my '51 properly, except it has a water bypass tube which is incorrect for my '51 (which has the internal bypass). On the other hand, I bought a brand new housing (the one on the right) that was supposed to be the answer, but it isn't for two reasons: Reason Number One: The new one doesn't point at the radiator and it causes a solid hose to kink badly. I've tried. Reason Number Two: Even worse, the outlet on the new housing is 1/8 inch wider than it should be. It does not match the radiator inlet. Both should have a 1.75 inch outside diameter. I've searched the internet for a part that looks like it will fit correctly but I have come up empty. So, unless someone on the forum has discovered the perfect solution, I'm going to have to fabricate a housing from scratch that actually fits properly including a tube that points in the right direction. I just wonder where all the original housings have gone. I've never even seen one.
