So rang around the Jag dealers at 9am yesterday morning, and either no answer from the main reception after the initial IVR bit, or the 2 I did get an answer from said their parts were closed due to some sniffle thing. Managed to get through to 1, but he didn't have in stock.
So got her on EPC to check for the crossed referenced LR part, and found LR dealers much more helpful, though nearest with stock was between Cov and Brum. So up we trundled in the Battlebus, once we got that started*
£38 later, I had the part in my grubby mitts, but we had to detour to Hobbycraft and the recycling centre on the way back, due to her needing bits for some project that I dont understand the point of. Also detoured via Jennys Resturant for a takeaway burger and chips, seeing as it was about midday..
The part fitted easily, though it took about 3 hours, as I was dodging showers, which also left plenty of time for the coolant to trickle the air out. And by 4pm, it was having its test drive, about 20 miles of local roads.
Suspect over the next few journeys, it may bleed a bit more, but probably not much.
*The battlebus is an arse to start with low fuel, and when it does fire, its smog city. Several neighbours were out chatting, and were laughing, seeing as I'd caused commotion the night before with the Jag on a tow truck, and then the Zaf wouldn't start
