Guys
Bought an Evoque yesterday and on the way home the coolant fill message came on. Checked it this morning and level is only slightly below fill but on taking the cap off the bottom thermostat bit is stuck in the tank. How do I get it out? I just haven't got time to go back to the dealer and leave it there unless its a major problem.
Any ideas?
Thanks
Ian

Similar issue on the RR Sport, the link here seems to suggest that the float becomes saturated and therefore ineffective, and a new bottle/tank is required. How old is the car?

Thanks for the link thumbup

The car is three years old/27000 miles. The coolant level is below minimum by about 25mm so it may be the float is ok but I will bear the info posted in mind once I have topped up if I still get the indicator saying coolant is low.

Bearing in mind I have only had the car 12 hours I don't know anything about them. The problem I have is the expansion cap "appears" to be in two parts with the thermostat part pressed into the cap. I have taken the cap off and it has left the thermostat part stuck in the top of the tank so I cant put any water in.

Does anyone know if the stat bit is threaded i.e. unscrews or does it simply pull out? Obviously if its a major problem I will take the car back but that involves a lot of fannying around that I could do with out if its a simply fix.

Thanks

According to microcat the diesel & petrol use the same tank & cap.
Cap part number is LR000243 & a pic of it is here:
Click on the pic & you get a view of what the top & bottom should look like.
Doesn't seem to be anything else shown as replaceable in the tank.

If you want to have a play with microcat then it's here. Left click on 'Open new catalog' then left click on your vehicle & take it from there. Have fun smile

Thanks Paintman,

Its very difficult to explain but the cap is in two parts, the bit that screws on to the tank and the thermostat part that attaches to the cap and fits in the neck of the tank to allow expansion and release. The two bits appear to attach to each other as a push fit and would normally not be taken apart.

I have taken the cap bit off but the thermostat bit is wedged in the neck of the tank and I cant see how it comes out. I think I will drop by LR later today and buy a new cap and then should be able to work out how I am getting the thermostat bit out of the neck of the expansion tank.
These things are sent to try us, lol.
Cheers

Ah. For some reason the link to the pic is missing, so here's a second go:
http://www.oscaroparts.com/genuine-engine-coolant-...

Whilst I've not taken one off the current crop of Land Rovers it sounds very like the plastic screw tops currently fitted to many vehicles - usually to vent and release overpressure not as a thermostat. The one in the pic is 21psi.
If that is the case with yours then it sounds as you say like the top has come away from the bottom. Might need a bit of persuasion to come out - if it's plastic a hot screwdriver pushed into the middle & turned might work - but once you've seen the new one it'll probably make more sense as you'll see which bit is threaded.
