Thanks Simon I had found a good explanation on this forum that was linked to from one of the other 4x4 forum sites. So my explanation is that the fan free wheeled as the radiator had lost so much fluid that it was cold so the valve had closed.

LOL

Thanks Simon098 I did need a new radiator and had one fitted, I thought I had mentioned that. I don't think the new fan is working properly. I read every post I came across trying to get an understanding of how the viscous fan work. That's why I was puzzled that the fan could be spun really...

Thanks sierrafery just what I needed to know. Update: tried the test and the fan stopped. Also tried it at 2000 revs and it stopped. I have fitted the new one and after coming home last Wednesday I tested the fan.whilst the car was hot. I could spin the fan it was totally free to rotate. I...

Hi Neilly just to confirm the thermostat is fitted the correct way.

I see no reason why a car should not last for years and years, provided its maintained properly. I accept that a manufacturer can not afford to provide a warranty for that long. Never mind about your mate having the same issues as me. I doubt it. I read plenty of stories of Land Rover owners...

Both hoses going to the thermostat have been replaced. I dont know about the conditon of the other hoses beyond the two metal pipes. One of the junctions of a metal pipe with a hose has been repaired with an epoxy filler as there was a leak- the metal pipes are expensive. You mention ". . . is...

Hi Simon098 I have fitted a plastic bottle to monitor coolant loss through expansion tank cap operating.

Thanks johnlad I hope the leak is not happening where you describe as that means that I would not be able to pay for a new cylinder head and fitting it. My motorway section of the 34 mile trip to Swindon was done at a steady 50-60mph. I am awaiting delivery of the dye and UV torch, fingers...

Just bought one :)

Hi johnlad. There is no evidence that would suggest that the head gasket has gone since it was replaced last June, it was sent for testing for a crack at the time. There is no oil in the coolant and no coolant in the oil, it passed a sniff test OK. As I have not got rid of the air locked in...

Just undoing the bleed screw -without touching the expansion chamber. Very little bubbles of air escaping.

Thanks worth checking. I did replace a hose to the thermostat that split - had to be taken home by AA. So I have not interfered with it until I had another problem so changed the thermostat. I had a look a the car but couldn't take a photo unless I remove the fan. Looked at the AU post and...

Hi Avago The car is dry inside. I presume that a leak would be inside the car.

Topping the expansion container up in the raised position then bleeding the system. Also parking the car with the bonnet uphill and before next use bleeding the system.

I had not been removing the bleed screw (item 5) when I topped up the coolant.

Hi Neilly When I top up the expansion tank I raise it using a plank of wood so it is higher than the top hose. When I bleed the top hose I do not have the expansion tank elevated. Is that wrong? I am parking the car facing up hill so the bleed valve is higher.

Update. I have fitted the new cap and carried out a sniff test. The sniff test passed. Driving locally within a range of less than 10 miles each way the car is OK. There is little loss of coolant. However going off to Swindon last night a distance from me of 34 miles it overheated at about 33...

Right thanks

Hi sierrafery My existing tank cap has a spring and I cant see any pressure valves. The replacement cap (bought on eBay yesterday) does have two valves showing and no spring. It is listed for D1D2 as well as Defender and range rover. The sniff test can be irrelevant? Can you provide some cases...
