Thread: Oil Cooler Do I Really Need It ??

With respect, if not too late, I think you should take the advice of the others and get made up hoses from a hose doctor.
The OEM ones will invariably start to leak again after a short period and are truly a false economy.
I'm surprised Ritters didn't recommend this too. Most of the aftermarket LR specialists can now replace with made up hoses rather than the OEM. ( I had mine done at Range Rov three years ago and not a problem since. )

Just because it has a LandRover sticker and part no. on it, doesn't ALWAYS mean it's the best.
It is possible I suppose that the design has changed on the OEM ones -but I doubt it.

The oil cooler hoses are a known issue with all Tdi's in Disco's, Defenders and OS RRC's.

All most all of us do is take them off and use Pirtek or Enzed brazed on adapters and hoses.
The problem is the original UK Dunlop hoses and crimps.
The local Pirtek even re-crimped them as a stop gap early on, but they started leaking again quite quickly.

If you don't run an oil cooler the oil temp will be far too high and kill the oil and engine eventually
......And every turbo diesel I know of runs an engine oil cooler, as do high performance petrol engines, it isn't there due to an engine design fault.

<edit> people don't realise how much of the engine cooling relies on the oil, and remember that engine oil sprays are routinely used on the underside of the piston crowns on turbo engines (including Tdi's) to pull temp out of the pistons. That temperature has to go somewhere. Normal engine oil temps just cruising down the highway hover around 90-100*C, up to 110*C in winter just climbing a hill on the highway. This is a pretty average sort of range for any diesel engine.

<2nd edit> Which engine are we talking about ??
Tdi's have the cooler built into the radiator header tank, TD5's have the heat exchanger built into the side of the engine with coolant hoses running to it, just like Nissan and everyone else use.. ??
