Re: Thermostat - No Grommet
Without the grommet, it won't seat correctly, and might as well not be installed. I strongly advise that you do not run it for long periods without it, however.<br />This is because coolant will over-cool some areas, while under cooling others, creating holy piston symdrome or warping the head.<br />you might be able to make one by wrapping a bead of high temp silicone around the t-stat,and letting it cure, then, installing it.<br />But a new t-stat costs about the same as a tube of goop (9buks), and comes with the grommet.
