oil cooler issue.

[franks]

just wondering, those with an oil cooler....

after running around in your car for whatever period of time, whats the temp of your oil cooler core like?

is it so hot you can't touch it?

is it cool enough to touch for a little bit?

or is it cool?

i had mine installed a while ago, and i dont think its working. its practically cold after a good 15-20 min drive, and on the track i get temps of around 120-130 degrees...as indicated by my factory gauges.

cheers,

It should get quite warm, especially after a "spirited" drive. Even the oil cooler on the mini gets pretty warm after a short drive. Does your oil cooler setup have a thermostat? If it does, maybe that isn't working properly????

[franks]

i am suspecting the same thing.

i believe it does have a thermostat on the sandwich plate between the block and the oil filter relocation kit. its a trust-grex oil cooler kit. but i'll have to check it out as i bought it second hand.

Dunno if the trust kits have a thermostat. HKS kits do, they have an additional return line for when the thermostat is closed.

Pay Anthony a visit, he's got one of each at the moment so you can do a comparison. There's a big difference.

[franks]

yeah rightio! thanks for that bit of info!

[jvs007]

dudes, isnt 120-130 deg. quite high ???

i got a grex oil cooler and the oil temp sensor is off a sandwich plate where the oil filter is. on my gauge i dont think i have ever scene it above 100 deg, even after givin it a bit. mind u i have never been on the track.

[franks]

Grrrrrrrrrrrrrr yeah it is very high...

[T0nyGTSt]

Grrrrrrrrrrrrrr yeah it is very high...

Dude...

You may as well not have an oil cooler.

Something is definitely wrong.

define ur install, where is the cooler sitting, how/where is it connected ??

[franks]

hahah thanks tony

the grex kit consists of an oil filter relocation kit and core.

the core is sitting in the standard kit position and that is just left of middle behind the grill, in between my front mount core and my a/c condensor.

i didnt install it, it was installed by c&v, removed from one car and then straight onto mine. from the block there is a plate replacing the oil filter. two braided lines run to the oil filter relocation kit. from this plate, where the oil filter sits, 2 lines run to the core.

the core is dead cold, the braided lines from the block are warm. i suspect the problem is lying with the plate where the relocation kit sits. but i'll have to check those lines from the block again!

in any case, its going to the workshop thursday morning. i just hope its something simple...

Just thought of something really obvious.

Is the factory sensor reading the oil temp as it is leaving the block, so before it gets pushed through the core.

I only installed an oil temp gauge on the weekend but have noticed that the oil takes a lot longer to heat up than the water. The sensor is reading the temp in the sump which probably has something to do with that, as there is a reasonable amount of oil sitting in there to heat up. Once it is heated up though it stays pretty consistantly around the 90-100 degree mark.

If there is a thermostat in the relocation plate then what you are describing as happening makes sense. Say the thermostat is opening at 100 degrees for example, for every day driving it will almost never direct oil through the core. Then on a track day it's obviously seeing higher temps and going through the core but you are seeing the outgoing temp after it's circulated the block. It's kind of like plumbing a water temp sensor into the top hose of the radiator to see the outgoing water temp from the engine rather than seeing the cooler temp after the radiator.

Frank: your oil temp is reading awefully high dude...mine reads no higher then 95 degrees during normal drives and goes up to 100 when punting it a bit. I've also set warning 110 degrees. My sensor is also reading straight from the oil cooler and not from the oil lines on the block itself. Also what kind of oil are you using?

[T0nyGTSt]

I have a very Anglo/Yankee cooler setup (Serck-Marston/Earls) and you should be able to work out that the car runs very cool even in our Sydney heat. It's never even close to 90c!

just to clarify guys, my oil temps are perfect for everyday driving and also for a quick squirt. they only reach 130 when im on the track and after i've done 3 hot laps.

BHDave: i am unsure where the factory sensor is, i'll find that out tomorrow i had the impression it was sitting on the block where the oil filter plate is...but im really unsure

[franks]

core (this is cold even after a squirt):

oil filter relocation:

braided lines from block to relocation plate (these are quite warm):

braided lines from relocation kit to core (these are cold):

[BHDave]

Did you end up getting it checked out? Any probs or is there a thermostat in the relocation plate that is causing the behavior you describe?

BTW, thats a bloody big oil cooler

[franks]

i'll let you know this weekend, i couldnt get around to the workshop today, so im goin on the w/e.....

its not thaaaat big
