Convertible top problems

(Gary Mees) #1

Recently I have had a number of issues with the convertible top on my 99 XK8 and have sought advice in many places in doing so I stumbled across Marvin (no not the paranoid android) he can be contacted on 1-888-317-9340, he is extremely helpful and also sells parts you might need, not only that but if you can’t fix it he will fly to your location and fix it (yes you do have to pay him) he is a lead technician and knows his shit.

Please note I have no affiliation to him I am just recommending him because he is very helpful.

The December issue of Classic Jaguar has an article on repairing the top on X100’s

Thank you I’ll check that out
I assume you mean December 2018 ?

Yes. I was going to say “this month’s issue” but the issues are always a month late, here in the colonies.

I fixed it, YIPEEEE

The roof would open ok but when I tried to close it the roof would struggle and sometimes I had to try a couple of times, when it did make it the catch wouldn’t raise and therefore I couldn’t lock to top.
I disconnected all the hydraulic lines and blew them through all but one (the line from the pump to the headrail marked ‘F’) this line was partially blocked and after spraying lots of brake cleaner down it a load of gooeeyy fluid came out, when I finally got it to flow freely put it all back together with nice new fluid and it works perfectly.
Apparently this is a known problem that the fluid turns to gel .

Hope this help someone in the future.

Jaguar issued TSBs for this fault 20 years ago!!!

The yellow UNIVIS was replaced by green PENTOSIN CHF11S for MY 2000.
I still have a tin of UNIVIS in my collection of antique Jaguar parts!!!
