thermostat and gasket

Went to replace the thermostat on the 90 (97) with a 160-degree (Stant 45356, NAPA 530060). However this one doesn't have a vent hole up top. Anyone using/recommend this?

Also, as to the gasket: can I use any old paper type or must it be metal? I don't mind metal but is it readily available from the chain stores?


BTW, The one I pulled out is a Waxstat 106.

You can also drill in a vent hole if you want.

Also, I've used generic 2-hole paper gaskets without any problem.

Five minutes after I posted this I thought of just drilling it and using the plastic jiggle thing from the old one.

The factory shop manual describes it as a "jiggle pin" - jus to be completely accurate.

Update

Well that was easy enough y'all. Except for the chunk of skin I took off trying to gently remove the thermostat that was in place. That rubber sealing ring works great.

So I installed the factory recommended thermostat (part number ERR 3291) with WAXTAT stamped on it. The one I removed looks identical only it has WAXTAT and the number 101 stamped on the face.

I refilled the radiator and tested the truck. The temp guage read about half way between the half and 3/4 mark on the guage. I just drove around for about 5-6 miles in traffic with and without the AC on.

That sound about right?

Well, as I have noted elsewhere, you can see temps of 225 at the halfway mark. If you're at 60% or so then you're probably at 230. I'd say if you're over the 50% mark then something's wrong. I've always been at just below that even with AC on the hottest days. Recently it crept up and that's when I also had noticeable coolant loss.

This is a 300Tdi in a 1984 One Ten. May be different than the NAS 90, but my next step is to have the radiator flushed.

If you're normally running at 60-65% I think that's not right. Then again you are in GA so perhaps this is OK.

My other setup is the same (110, 300Tdi). Only had it past half-way once - really hot day, AC on, going up a hill in fourth, don't know the EGT's as I didn't have a gauge then. Let off the gas and temp went down.

Could have been first sign of my radiator going as I replaced it about a year later with very little miles put on since this incident - totally rusted out.

Will see how the new recore goes once I get the oil cooler lines done.
