Picked up my first l322 today and my first post on here, so hello all.

It’s a 4.4tdv8 with 213k miles, I drove it back home (roughly 230 miles) and everything was fine. I did notice however that the temp gauge never sat in the middle and on the odd occasion when I looked at it, it seemed to be lower than when I last looked.

My question is, where is digital needle “suppsosed” to sit when sat at say 65mph for a few hours on the motorway? Does it fluctuate and sometimes go below half way? Seemingly all other cars I’ve had the temp gauge sits bag on in the middle and never moves.

Picture of car just because and also temp needle, the is was after 2/3 hours of motorway driving.


Thanks

Should stick bang in the middle almost certainly a failed thermostat leaking excess coolant into the radiator. The remedy is to replace the whole thermostat housing inc the top part. Even if the top part is reusable the plastic becomes brittle with age and they break during dismantling. 2012 TDV8 Vogue (L322)

Thanks for that, am I going to do any damage to it if I drive it whilst I get it booked in somewhere?

I’d drive it gently until it’s fixed. It may prevent the DPF regeneration cycle from starting so best get it done without too much delay. Just remembered when mine went bad that the actual thermostat and it’s housing can be replaced on it’s own which makes the job easier but it’s not available as a spare part and comes with the whole coolant mixture assembly so depending on how knowledgable your local LR Indy is you may get lucky with a cheaper repair. 2012 TDV8 Vogue (L322)

BTW also check your coolant level in the header tank. 2012 TDV8 Vogue (L322)

Also it is worth replacing the O rings in the big hoses that connect to the thermostat housing from the front. 2012 Vogue TDV8 in Aintree green over sand
