1pz parts question (specific?)

[decoco]

Looking at a few parts number for a PZ Oil Cooler cover and I see two different part numbers. One with a nipple and one without. What is that nipple for?

This is the part without the nipple: 1572117010

This is the part with the nipple: 1572117020

The oil cooler cover on my 1993 PZJ75 does not have that nipple; only the blank boss in part 17010..
Maybe its for a PZJ version with a turbo ???

Thanks for your input.

My guess could be on a circulation heater

That certainly is a possibility....
Here in the PI rarely do you see heaters installed in a vehicle... unless the vehicle was imported from a colder area.

That nipple is for the ACSD (Auto Cold Start Device). Often Deleted on vehicles to eliminate one failure point.

Most of them never had a ACSD. Its also a 1HZ and possibility a 1HD T oil cooler

No such thing from the factory.

Beno,

Thank you for the clarification...
I am still learning all the variations that were available...
