Thread: Another couple of LR engineers on hit list hoses

Great idea.
I will rememebr that one as it brings the nut to a reachable vs unreachable position.

Mine is an EU3 02 model and has the restrictor and the single small hose on the radiator.

I received an extra hose with no home with the kit so I guess in the older system that it connected directly to the oil cooler pipe from the second stub on the radiator.

Yes, mine is an EU2 model, where coolant from the oil cooler, thru the secret hose , is delivered to the top spigot on the bottom radiator tank , then thru the bottom spigot to the fuel cooler, then thru the thermostat , making its way, with the coolant from the heater return hose , to the suction side of the water pump. via the heater/ expansion tank return hose. When LR modified the radiators, the new ones were full flow, no bottom tank, making the supply from the oil cooler superfluous , thus making it possible to take it out of the system. I have not seen a diagram of the EU3 cooling set up, but would be interested in checking out the differences, if any one could post one up, cheers, Bob

Ahh the joys of getting to the fuel cooler.
Been there



Even found a relatively painless way of dealing with the R type clips, without having bought a pair of the pliers.*

I wonder what demented mind thought that up?

Now AFAIK the water goes from the bottom spigot of the full flow radiator, via the restricted flow into the fuel cooler then through the thermostat across to the hidden hose and into the oil cooler.

I guess it is so the oil is not overcooled.

I don't reall know how the thermostat works as it is in the end of the fuel cooler which goes directly to the heater and the oil cooler pipe is teed off.

You can see the thermostat through the oil cooler stub. Maybe it directs all water to the heater when cold then splits it when warm between the heater and the oil cooler.
The outlet hose for the heater goes across the back of the engine, joins a pipe that runs along the top of the heat shield, then into the top radiator hose .
A bit simpler than the previous setup.

Yes, it looks a can of worms, until you sit down & nut it out. The Thermostat in the fuel cooler on the EU2 opens at 82 degrees C ,& according to RAVE, is there to prevent the cooler operating in cold climates. The thermostat is in the ' T ' connection at the back end of the cooler , the 'T ' connection provides a connection for the the coolant return from the heater matrix & fuel cooler. Would really like to see a drawing of the EU3 coolant system, to see the changes made. Bob

Child labour? Or Monkeys?

I have better things to do than worry about what you do or don't do to your D2

Oh, so it WASN'T you who sent a hitman after me chasing me down the street with a set of Clic - R type pliers?
..Awkward...
