Rb26 Grex Oil Cooler

[MJTru]

I have a grex oil cooler kit for my rb26 build. I just finish installing it and was wondering what this valve for. Its it like a thermostat that only opens to cool the oil only when its hot. Or is it some sort of pressure valve.

Oh Thanks mate that was simple enough just wish I had a proper diagram for the installation.

A quick question here. Is keeping the oil cool better? I ask because that's the whole point behind getting an oil cooler right.?? So because I live in a Caribbean island thats always hot. Very close to florida. We have no winter here. This thermostat would make no sense wouldn't it. ??

If that is the case can I remove the thermostat from the housing and have it cool all the time. Or is it important to warm the oil up fast. ??

You pretty much answered your own question. You want oil at the correct temperature and pressure as soon as possible. The thermostat provides that. Just because it's hot where you live definitely does not mean you should take it out. Once the engine is up to operating temperature the thermostat won't be doing anything anyway really.

Thermostat is for fast warm up (as well as to prevent over cooling in cold weather). Fast warm up is good for engine life, emissions, you name it.

Also make sure you research which way the hoses go as with a thermostat system if you put it together wrong your in for a world of pain

Thats the first thing I did as I was building the motor. I made sure the flow direction was right. After double and triple checking the systems flow direction. I can see how getting it wrong would cause major problems. Before this build I had mest the direction of the flow up. So this time I just didnt find the installation instructions. I started from the oil pickup and work my way through it. What not good about the grex oil cooler is the stamped arrows that point in the direction of the oil flow. There underneath the oil filter block. They should have placed them on top. Thats what caused me to mess it up my first time. But It didnt happen for a long time. In about 5 minutes I realized it right away. But that motor ended up spining a bearing in about 15 minutes of driving with no kind of hard load condition. Lol. Guess that mistake was what caused the failure.

Im only noticing one problem right now from the day the motor started. My radiator system isnt pressurizing.
