This setup replaces the factory oil cooler/warmer. The factory oil cooler/warmer warms up your oil and maintains it at coolant temperature. This cooler / warmer often leaks, or can not be reused due to damage or contamination. When using this delete kit vehicles must be driven carefully, with no high rpm driving until oil temperature warms up.

Parts Needed:

• Block plug
• Oil filter stud Part Number: 15213-31U00
• Thermostat (without coolant hose fitting)
• Gasket

Advantages:

• Cleans up the engine bay a lot
• Gives you a clean place to put an external cooler sandwich
• No worries about it containing debris. They are just bad news for highly modified cars. Many engine builders will tell you to just replace that cooler every time you build your engine because it gets so clogged up with debris and they are impossible to totally clean.

Disadvantages:

• None

Part Number:

I’ve never heard of a Vq35HR having an oil cooler/warmer. Here are a couple of pics I took:

Stock VQ35DE stud

The reason why you need the VQ35HR oil filter stud. The shank is way too thin to use with an oil filter block and too long to use with just a filter.

The VQ35HR filter stud

VQ35HR filter stud installed on a VQ35DE. You can see why you will need it.

3/8BSPT threads not NPT

For those of you that are deleting your oil cooler. You can also get one from a 3.0 as it comes plugged.

That’s the plug for the rear pipe that goes to the oil cooler.
