Oil Cooler under rear mudguard getting HOT...

Well,
after trying out 4 different oil coolers including the doghouse cooler both in the engine bay and outside the engine bay..
I fitted a larger oil cooler under the rear RHS mudguard .. and drove around Town for a few weeks ... I then hooked up a temperature gauge to the sender in the type 3 dipstick hole.

YIKES....
75C around town... 60 KMH highest speed.. maybe too cold??

Yesterday I drove down the highway 30klms with the gauge going UP to around 118-120C at 80-90 KMH...

so, it seems that at speed , the air isn't going thru the oil cooler...
so I need to lower it down into the air flow or fit a good fan to it

I haven't done either as yet...

behind My oil cooler is the ATF [automatic transmission tank] so
it may be this that is stopping the air flow....

the Best part was when I returned from the 30 + 30 KMH trip
inside the engine bay was COOL....
and I have closed My engine lid for the winter....

I didn't do the oil dipstick test.... lol

but placed My hand on the alternator and fan shroud.... COOL
so, that is excellent.....

People keep telling Me I should have stayed with the doghouse oil cooler... and maybe I would have... had I seen how cheap the New doghouse oil coolers are now...
But We do what we do... 😊
