So a little background, I have recently done a complete overhaul on my 4.2sc. And while everything was apart, I noticed the small coolers and wondered if deleting it and not having water and oil potentially mix is possible?

So my reasoning is that
- the engine oil has its own relatively big radiator (behind the headlight)
-the parts to retrofit are cheaper by ALOT in comparison to ONE oem oil cooler (we will be deleting 2)
-i want to add more sensor readings to monitor temp. Having thermoswitches to activate retrofitted electric fans allows for measuring oil AND trans temps.

What I plan on doing is

Engine oil cooler

- remove the Oil cooler lines from the filter housing to the small oil cooler and replace with a properly sized U-Shaped hose.
-the water side fittings on the oil cooler will stay in place so I dont have to deal with the spider web coolant hoses
- Installing a thermo activated electric fan to the big oil radiator behind the headlight (theres enough space to fit a slim type fan)

Trans Oil cooler

-fitting (behind the opposite headlight) an aftermarket radiator (about the same size as the engine oil one) with the same pipe diameter as the trans oil cooler lines. Cut off fitting and connect with jubilee clips
-same as the engine oil cooler just leave the water hose lines intact with the cooler.
-Also intend to install another fan for this radiator as well.

Costings

- 2x12-inch electric fans ($80)
- 2x thermostat switch ($30)
- silicone U-hose ($10)
- a few feet of hoses ($10)
- Jubilee clips

Total $120. An oil cooler on LR parts (Pn LR015152) is $190, genuine one is northward of $300! If you go down the trenches their about $50 for the aliexpress special 😅

I understand its not for the purists but I cant really justify buying oem since i got the car for peanuts. Roast away if you dont think its a good idea 😅

They have to make the cooling system work while towing a trailer across death valley with the aircon on full at tickover with the cooling fan only just moving.... IMHO the standard cooling is well over the top....

I removed the original engine driven fan and put twin electric fans, off a Jaguar, on fatty off roader with a thermoswitch and it worked fine and kept everything cool...

I think an air to oil is a better idea for a rad than the oil to water that is fitted, although they do that so the oil warms up to temperature quicker so it's not just for cooling...

In Sarawak you are rather close to the equator so I'd keep a good check on things, get a laser temp gun and take lots readings before you start... Just my 2p.....  Pete

Thanks for the insights 😃 this car will definitely see ZERO towing work. Just a casual weekend cruiser.

I wanted to do the viscous fan delete but I was worried about leaving the fan connector unplugged. Which jaguar setup is it?

Jaguar S type, there is info about it in project fatty offroader, link in my sig strip... you need the soft start relay that is attached to the fan housing an 80amp supply and the thermoswitch...


It fitted the 4.4 petrol V8 rad perfectly, I think it should fit yours... Pete
