I have pulled my motor out and while stripping it down to the block I noticed what looked to be an oil cooler location.. I’m not to sure if it’s a block off to an auxiliary port to hook one up. If anyone is able to explain how it works that would be great, Thanks!
It’s a 1989 Toyota Pickup DLX 3vze 5spd 4wd
Mine being 2wd, not knowing how or if the 4wd would be different, but their are two different water pumps you can get, one with a water outlet, one with out(yours), and the one with a water outlet connects to the oil cooler with a hose, and then back out. see pics. There are also brackets holding the oil cool down, and Ive heard the oil coolers them selves used to be quite expensive, nowadays a cheap junkyard find, and the oil cooler gaskets (3pacK) cheap online
Do you think it would be worth finding another oil cooler and reinstalling that part of the cooling system? I know these motors have a tendency to overheat but I am not sure how effectively my oil cooler block off plate worked, I bought the truck and drove it maybe 15 miles before I pulled the drivetrain. ( School project to rebuild it, got the truck with 220k miles for $60 ).
The woman I bought the truck from said the head gasket had been replaced once around 180k miles.. If the oem oil coolers weren’t very effective I’ll probably just buy the gasket for the block off plate and leave it at that.
I dont see why not, only beneficial in the sense to keep er’ running longer, be sure you get all the components for it though, easy find at the junkyard. Includding the valve 15777E in diagram
I'm currently doing a 3.4 swap and my JDM engine came with a blockoff cap like yours. Since I was doing a timing belt anyways, I went ahead and got the water pump with the oil cooler outlet, and snagged the oil cooler off the old 3.0. Had to get a little creative with the coolant hoses but it worked fine. I liked the idea of the engine having it's best chance possible of a long life.

This was my thought exactly, I also ended up using a oil filter gasket (square cut o-ring) that fit inside of my oil cooler instead of the factory one. I blew the factory one right out when i primed my oil pump after the rebuild.
Parts store people thought I was crazy after spending an hour looking at every oil filter, but no problems since!
Had to dig around in the toolbox a little bit to find the receipt but the part number is:
MGL51040 (I think this was a microguard)
As far as if concerned you can use any “51040” but I just got the cheapest one they had, just because the o-ring is most likely the same.
What I did was put some motor oil on both sides of the o-ring and push it in the cooler. The o-ring is going to be just a little bit too small, but it’s close enough in size to get it in there.
