hi paul
MPG figure came from trip computor - not an actual fuel bought/used calculation.
However, generally I felt the figure was reasonably accurate against what I spent on fuel.

I,m changing spark plugs on my 96 celebration 4.0 AJ16. Current plug fitted is as specified by manual Champion RC9YCC. David Marks confirmed he uses these as service replacements. However - on Jag lovers forum (mostly USA imputs) it said this plug has been superceded by RC12YCC - a hotter plug. I ha...

hi keith a car cover, indoor or outdoor has no effect on the relative humidity of air which carries the moisture that rusts our cars. They prevent dust, scrapes, UV light etc but can actually prevent moisture from evapourating away from saturated surfaces. Generally in an average garage they are ok ...

info from he who knows the average UK temperature is 10.2 degC the average relative humidity in UK is 80% theres roughly twice as much moisture in the air in summer than in winter at 0 degC and 50% r/h theres 1.8g/kg of moisture at 10 degC and 50% r/h theres 4g/kg of moisture at 20 degC and 50% r/h ...

converted mine to twins recently and have originals available -both in good working order with trims- one securing lug on chrome trim off but it would still fit ok.
Anyone interested email me.

Paul Checking the notes I made whilst getting quotes for the box fix the deal from Jag Classic Spares (Glyn Parks) was actually £2851 + Vat and it was "exchange". I assumed it would be a new box and I had to return my old unit after it had been removed. I did not receive a written quote as I spoke t...

Ive just gone through the same saga in my XJS 4.0 celebration 1996 - ZF249E box - ended up having to have a complete rebuild. (4 weeks ago) Same initial symptoms - then gradually took longer to engage on start up followed by rough gear change. Tried to salvage by replacment filter and fluid change b...

Success at last - I think Finally found time to do long run after gearbox fix and to see how the temp reading was doing after all the tests etc - Did 500 miles this weekend and the gauge reading was just about spot on N reading all of the time - I can only assume by taking the sender through the ful...

Readings checked as temperature dropped. Readings as follows All temp readings in Deg C. temp. Ohms temp Ohms temp Ohms 98 86 89 110 80...

thanks for that reply graham - Car away this week (gear box fix) When I get it back next week I'll do resistance check through the temp range and see what it comes out like. I'll post the results so if you could recommend a resistance from that I could easily fit it in. I could even end up a happy b...
