Thread: Temps - these ok?

As I sort of hi jacked thread thought best to finish with where I'm now at.
Oil cooler replaced (along with coolant), same rd same weather, same speed. Oil temp 135 before and today 115. Oil temp sits around 20c more than water until load is removed after which oil takes a little longer to cool than the water.
Appears my issue is fixed however will only load the trailer up again beginning June. Pretty confident though.
Interestingly hard to say if there is any perceivable issues with the old cooler. Water flows through it, and can blow air. Can feel restriction but didn't see the new before going in to compare.
Thanks for people's inputs and the original post which prompted me to sign up after 12 months to be able to post

Travelling over the last few days I have tried without the spotlights, without the winch (with the lights)- both no improvement.
Today without the winch along with the front number plate removed and it seems to have improved, sitting on 100kph and 135C or less was the norm. A couple of final long pulls up hills did see temps up to the 140 at the very top (coolant also increased to 104). If I wasn't monitoring I would never have known as the down hills on the other sides reduced the temps while not having to give much throttle. It does take a while to drop though as there appears to certainly be some heat soak in the engine.

This makes me curious as to the airflow, the majority of the radiator is actually fed from the lower section of the bar, it's actually shrouded and encased somewhat to separate it from what enters through the grill. Removing the number plate would have done little more than change pressures and air movement behind the bar as directly the channel where the number plate sits is no radiator.

It is in for a service as soon as it can be booked in and I will be having the plastic coolant housing that cracks replaced at this time (preventative). Will be asking to ensure a complete flush and obviously fresh coolant. In the meantime am pondering over the whole airflow thing. Will load the winch back in and try again still without the number plate.....

Has anyone ever fitted a secondary push fan to the front of the rad? I also run a bit hot towing and have a bullbar, winch and lights fitted. I wonder if a decent push fan would account for the loss of ram air.
