Thread: What happened to your Discovery 2 today?

About to pull the motor out..

TBH the cooling system is a joke how many joins do they need... wtf were they smoking when making this...

design engine to fit in bay...then as an afterthought work out how to plumb it

Post #8443, I simplified it

Should it have read "How many joints do you need..."

Thanks I will take a look, I was thinking what can I do to make this simple.

I wonder if the fuel heater/cooler thing is really needed. I thought I could at least get a non EU3 expansion tank to get rid of the EGR cooler coolant flow and pipes.

Then I was also thinking can I just do away with the factory g/box cooler get a aftermarket one mount it else where and install the Manual full size intercooler. Now to google if any one has made some pipe setup for the cooler lines or find a hose shop to make some thing.

Just returned from our first big post Covid trip in the D2.

4500 km round trip from Melb to Maryborough and Fraser Island - first time there and definitely going back!

Headed up via the Newell and returned via the New England hwy with some nice Nat parks and family outings.

Fuel use averaged 11.8 L/100km fully loaded with 2 Oztent bags on the roof. Not towing.

Only one minor hiccup with the D2 - wife was driving and heading up towards Stanthorpe power was down. I said keep driving as I plugged in the Nanocom. Could see boost was fluctuating so suspected a wastegate issue. Sure enough the small hose from turbo outlet to waste gate modulator had popped off. Back on with the correct spring clamp from my spares department and all good 😊.

Was earlier thinking of selling the D2 but it’s such a great simple heavy duty touring machine it’s not leaving our family!

Installed the Davies EWP and EWP Controller (which acts as your thermostat), at present have returned to the standard fan but have plans to go back to electric in the future.

Have a look at the pictures, the return to the top radiator hose has been removed (more about the internal heater than anything) and cut the rear of the front cooler pipe to fit the EWP next to the crossmember. This does not require the mechanical pump which I just removed the vanes of a new one and fitted the casing back.

The upper hose on mine has two inserts as besides the temp probe for the EWP Controller, I also have low coolant alarm. The Temp probe essentially replaces the return hose from thermostat - cut it out and put the temp probe there.

There is shortening of the coolant pipe (after removing the return pipe) which was about six (6) inches worth. MUST NOTE - did install this at the radiator and it created all sorts of problems, in consultation with Davies Craig and the flow diagrams, the EWP must be installed in this position

This is the EWP attached to the modified coolant pipe, a silicon pipe was used with another pipe to the current waterpump housing

The hose from the radiator to the coolant pipe to allow for the extra length required is a magna top hose

Here is the EWP installed looking up towards the existing water pump housing.

With the standard Fan, I have the setting on the EWP Controller at 100C which gives me 100kph cruising temps in the mid 80'sC, low 90's at 115kph. It does take longer to 'warm' up but in WA should not be an issue. Could set the thermostat down to get greater cooling flow and maintain lower temps but with two trips to the desert and three to the Vic High Country this has worked very well after initially setting it at 92C




Can also recommend the RR P38 V8 oil cooler which requires just a little TEE bracket made and new fittings & Lines to the existing metal lines and then threaded R) angle connectors to the cooler itself

I did away with the fuel cooler tacked to the manifold a long time ago. Blocked off the two 19mm radiator outlets and the return outlet from the oil cooler area and removed that pipe too. Fuel temp still runs cooler than water temp even on hot days. Pictures are many many posts back.

If you put thermostat in top hose just buy an inline thermostat housing like the one I have linked. I was too tight with the money and wasted time playing with wreckers bits, even though it works excellently temperature wise.

At the wreckers where I just scored a NNN ecu the vehicle I got it from had the factory trans cooler bypassed with a smaller square aftermarket unit in front of the car mounted to the condenser, next to aircon fan.
