Hi to everyone. I completed the aftermarket oil cooling system upgrade (setrab oil coolers and custom made lines) cheaper this way than staying with stock oil coolers (accident vehicle being rebuilt). I would like to know if there is any sort of procedure that I need to follow to get the oil coolers filled with oil (need to test my set up for leaks). Also does any one here know at what temperature the oil thermostat opens up. I am not sure under which section of forum to post, so I chose S-type section. Thanks in advance.

 

I would fill it as normal, start it for a few min, then turn it off and check, and repeat.....Should not be a big deal if all you did was make it a lil larger....

Why not post up some pics of your work

 

Picks will come soon, tomorrow. Thanks for the reply Riski.

 

No prob, I like projects, just way too damn cold right now to play in the garage here

 

Is there an oil thermostat? I didn't know that, if it's true.

I do know there's an oil pressure switch and an EOT (engine oil temperature) sensor (readable by OBD).

 

I was unaware there was an oil thermostat either. I've never run across one in changing coolers. I just swapped coolers in my Rangie last weekend, lines but no t-stat.

 

Pictures below as promised. The oil thermostat is part of the oil filter housing assembly. If you look at the housing towards the top where the oil cooler lines connect, you will see a round cap type piece that is held down with two screws. That is the thermostat. I have the old filter assembly apart that was dameged, will take some pictures so you guys can see what it looks like.

 

I can see the RH oil cooler and lines & couplings but can't figure out what round cap thing you mean. Thanks for trying, though!

Being a 2006 car yours has split oil coolers which mine doesn't have, but I don't know if that makes any difference as regards presence of any oil thermostat.

 

Oh you really should have an oil thermostat if there's an external cooler but I was wondering the same thing. Is it there. Good to know it is. When it's really cold out you don't want a lot of oil going through the cooler. It will always have a trickle bleed when closed so that the air is quickly bled out after an oil change. I don't how much capacity the engine cooling system has but IF there were enough you could always put one of those oil-to-water laminar coolers to replace it. They are extremely compact and can be placed outside of air flow. The plumbing is more work though. There's already quite alot of that on this car ...

I put one on my race car a couple of years and instrumented the before/after temps of the oil and radiator water. It's amazing how much faster the engine really warms up (not just the water temp) it's also better to have oil and water temps closely track each other. No need for a thermostat when you've got one of these.

Thanks for the pics! Learn somethin' everyday.

 

Here are some pictures of my old oil filter housing. I have it apart so everyone can see where the thermostat is located. This piece mounts to the front upper oil pan on a 06 STR.

 

I finally got my oil cooler primed and checked for leaks. Pipe work is all good, no leaks. Also if anyone needs/wants to know, oil thermostat opens up around 110 C and above. (about 230 F and above)

 

Wow, they let it get that high before it opens up. My Z06 never really gets above 190 degrees, unless im holding it at redline going 195mph, then it approaches almost 300 briefly.

 

I had the motor running for about 45 minutes at idle speed to see if the thermostat comes open, not even close. At idle oil only goes up to about 91C and stays there. I had to throttle my engine and keep it at about 3000 RPM to take it the rest of the way for the thermostat to open. I didnt think it would have been that high. Since this car has dual oil coolers, oil cools pretty fast.

 

Where in the NJ area are you reaching 195mph?

 

Not around here, when i drove across the country i was holding it to the floor in New Mexico for about 5 minutes straight at that speed. Here is a brief clip of cruising on the PA turnpike: http://www.youtube.com/watch?v=7_sLJus1rvg

 

I thjink I'd delete that.

 

Why, that video was taken over 5 yrs ago
