I think this is the case, some have them, some do not.

 

You need to install a temp gauge and measure before and after and see a significant temperature difference to make sure that the valve works as intended. I guess some say it works fine, probably because they never measured and compared the oil temps.

 

Yes thank you again for the help Extinct. Pressure relief bits happened to be already installed in the front cover. I unfortunately wasn’t able to get before and after temps. Ultra gauge is awaiting install. Can say that there is about a 10 degree drop from each side of the oil cooler with temp gun.

 

Back over here for the oil cooler project. I have a used factory oil cooler to use and appears to be fine from the outside. Doing a quick google and it appears cleaning the inside can be easy or super DONT DO IT! Anyone have thoughts on this? I was going to run degreaser through it several times, rinse and dry. The google says this might cause all types of problems. How hard and dangerous is it really?

 

@dswilly same as rad cleaning you could clog the passages. I suggest:

1. Getting some citrus degreaser regular household stuff
2. get thing to plug the exit hole
3. Stand the cooler up on end
4. pour the degreaser in until it starts exit then plug the exit
5. Pour some more in until it overflows
6. leave it for 15 minute or so
7. boil some water
8. Unplug the bottom and pour the boiling water through
9. Finally mix the degreaser with boiling water and pour through a couple of times
10. Then just a couple of pots of water
11. Let it dry for a day or so and you should be good.

There is noting that can hurt your engine or the cooler this way

 

Someone here said use gasoline.

 

Did the degreaser, appears to work well. Does anyone know if the oil cooler can be slipped into position without a total removal of the radiator? I hate draining and refilling coolant.

 

You can put it in place without disconnecting the hoses, just remove the top shroud and radiator mounts as well as the fan and it will push rearward for enough clearance to install.
