Come on guy's.. I think all senior members should be guilty of not saying it like it is..... The LR motors in the RR, Disco 4.0 and 4.6 NAS are the biggest pieces of f$cking **** know to this planet...For a so called prestigious car company to pin their name on this motor...well they should have been shot... A bunch of f$cking *** clowns...In all the 40 years of car and truck ownership ..This has been the biggest piece of sh$t I have ever owned..

If you plan on owning a Disco ...you should know from the get go it's going to ball up and go in flames... assume that and you will be ok..

I don't know, I see plenty of other cars and trucks in the junk yard, lots of Jeeps, some look so nice you wonder why they were scrapped at 170K... lots of things don't do well without routine maintenance. Rover selected an engine from an era when 50,000 miles was the lifetime of a car, people traded in every 2 - 3 years. That same engine was 180F stat in the early 60's, no one back then ran an aluminum head engine over 200F. Enter the pollution control departments, and we have to run at the bleeding edge. Keep boring out the cylinders for more power and torque and the engine "meat" gets thinner, heat problems go up. GM has made plenty of engine designs since then. One was in the Vega....

But high dollar vehicles have prestige, and plenty of couples get one or two to go with that new 4500 square foot home on a culdesac. And they lease the cars. And the stork flies over a couple of times. ARM jumps up to Jupiter. And the corporate ladder climbing owner is soon having to cut back on things. Enter to 25,000 mile oil change. Right before lease turn in. Happens with Mercedes, BMWs, Lexus, Audi, and on and on. We are not alone in the "these expensive cars are a POS" department.

BMW sludge, anyone?

 

Hey mate I have the same issue. No light no high temp.. but when I'm idle when the engine is worm and I turn the AC on I hear a knocking sound.. it maybe be your bearing that sits on the end of the fan. If it's the bearing that's a easy job if your mechanically minded but if it's the housing 😬 very big job need to take all front end off and most of underneath your engine.

 

mine starts around 190-195 if at idle or drive thru. If open road no tick really

 

What year model? if pre 2003, get an inline thermostat and a 170 degree thermostat, if 2003 or later get a 180 degree thermostat for the inline. The inline is more reliable and cooler than the factory Disco stats so it will keep it out of the tick range and keep the HG in good shape.

 

Mine is an 03 w/secondary air. Normal highway temps are at 188. Not leaking any coolant at all stays at same level and has been flushed also.
i would prefer a 170 thermostat in it myself

 

A 170 thermostat in a 2003 will trip a low temperature alarm. Some of the fuel trim systems also won't go into their regular cycles.

 

well that’s a bummer
