Z1 Motorsport oil cooler install, oil warning light at start up

Boss_302

I recently installed a Z-1 25 row oil cooler with thermostatic housing. I basically installed the cooler as directed and had no issues in start up. Did have to add a quart of oil. Primed the filter and cooler during assembly to minimize air in the system when started. The two things I didn't like about the kit was the oil lines could have been a couple of inches shorter. I was also not pleased with the Mocal adapter construction and machine work. I've done engine work in the pass so it was time to get out the die grinder and smooth the oil passage and sharp machine edges, The other thing I didn't like about the adapter was the way the oil filter extension fitting seats on the adapter. You have to be careful when tightening to get the socket fully seated so you don't strip the nut, 6-point socket is strongly recommended. Since all this I found that Mocal makes a new heavy duty more robust adapter for only a few dollars more. I would check the sensor's and wires and make sure nothing is damaged or grounded.

Cheers, appreciate your input. I'll look into the other housings.

Car is now back to stock and everything is back to normal.

Funny thing is that the oil pressure took time to build up, it also took a long time to release. Now when it's stock the oil light turns on very quickly after shutting it off (as it should). With the oil cooler system installed it kept the pressure up for a long time. To me it really seems like some kind of valve is acting up. But my mechanic took apart the thermostat after taking it off the car and he said everything looked normal with it. As it looks now, it's open when cold and then it shuts close when it's warm forcing the oil through the new loop/cooler.

It's a really strange problem this...

With my involvement in the assembly of the Z1 Oil Cooler Kit, if I recall correctly, the HD Cooler you are speaking about is too large to fit on the 370Z. There are many design considerations you have to consider. The frame of the oil cooler has to fit against the engine without contacting anything and be able to have the line attached. Additionally, even though the Sandwich plate has a M20x1.25 thread pitch, the diameter of the O-ring and O-ring seat are critical. I recall investigating a few models on the market that would "technically" bolt on, but the O-ring of the oil filter was too narrow and risked causing a leak. Keep this in mind with searching for alternatives.

There is a valve that moves in response to Oil Temp. It should be OPEN when cold. Then close off (EXTEND) when Oil Temps rise.
