Autozone part # 3846 for the thermostat cost about $7-$8 and no trimming involved! Part has to be ordered.

Drill a 1/8" to 3/16" bypass hole through the T'stat & mount the hole at the 12 o'clock position. Done!

What's the hole for?

Lets trapped air though

I'm not 100% positive, but I think that the hole allows a little water to go through while close. This keeps the temp from really spiking up before it decides to open thus allowing a more stable and uniform temp during warm up.

Just wondering because my 160 took a shit & I replaced with a 180 but didnt drill & it works perfect, so much better & for some reason runs down the highway between 162-165. Gonna pull it & drill it just to be safe since it is highly recommended. Thanks for the info guys.

What size hole do you need to drill ?

A Motorad 203-160 or Motorad 7203-160 are direct drop in 160* thermostats.

This is correct. No trimming needed. Can't remember if it has the vent hole but a properly bled system negates the need for this.

What size hole do you need to drill ?

They say roughly 1/8"

It's not really critical as long as it's bigger than an air molecule.

Does the hole need to be in the actual thermostat or in the outer sheet metal area?

In the outer sheet metal even though it really isn't necessary. If you do drill a hole I wouldn't make it any bigger than 1/16"

I have several i various temps. and they all camewith an 1/8” hole.

I drill the smallest hole I can. Typically 1/16.

I also went back to 180 stats in both cars.

I had to go to a 180 as well after I got an Alradico radiator.

Me too!
160 stat kept my coolant temps too cold with my ALRADCO and RMI-25 with 50/50 glycol
