Thread: Engine Saver TDV6/TDV8

There is no "low coolant warning" on a Land Rover Range Rover tdV8 3.6.
Ford ECU unlike BMW ECU in the td6 doesn't cater for that.

At 105k on the odo my RR tdv8 3.6 popped the top radiator hose off at the engine end and dumped most of the coolant instantly whilst driving in heavy traffic (20 kph) which allowed me to see the resultant steam and pull over within a couple of minutes. The AC even kept functioning normally which is a bit of a worry. The ambient temp was about 22°C. It would have been interesting for this to happen when it was 39°C and towing a 3.5 trailer as I frequently do.

After it cooled down I spent an hour getting removing top engine cooling components to get enough access to be able to pop the hose on again whilst replacing the hose clip with a proper worm drive clamp.

The temp gauge didn't register any coolant temp rise (as it was sitting in air rather than coolant.

If this had happened on the freeway at 110 kph then goodbye to a good tdv8 engine.

During my next service I intend to replace all coolant hose clips with worm drive clamps and fit a TM4 watchdog.

There is a level sensor in the expansion tank, which would not be of much use in your specific situation. I guess there's always a way to beat the sensors!
