F engine water outlet paper gasket installation order (1 Viewer)

[cc93cruiser]

Quick question... I have the diaphragm from an F engine cooling system/waterpump and I noticed I did not put the gasket on the pic ( letter D) in the correct order.. I put the thermostat on the lower piece water outlet and then paper gasket on top then the upper water outlet piece with rubber o-ring.... The pic here shows the correct order -lower water outlet/paper gasket/thermostat/upper water outlet+rubber oring.. Is this a big deal? I did coat both sides of paper gasket with grey rtv and used new toyota upper and lower water outlets (so there nice and flat mating surfaces)..... Any thoughts?

I do it like you did. Thermostat first. The SOR pic shows the same order as your pic. But the lower housing has a recess that accepts the outer edge of the thermostat. The t-stat sits down in that recess leaving a flush/flat surface for the paper gasket to lay on. I've had aftermarket gaskets with the big hole being the same diameter as the t-stat or slightly bigger. And I've had some that are slightly smaller. With the smaller hole gasket, the t-stat had to go in first or else the t-stat would pinch the gasket pushing it into the recess. The t-stat first will always work.

On my F155 the T stat flange sits in a recess in the lower half then the gasket sandwiches between the two mating surfaces. I just grabbed my old one to take a picture of
