Default 1999 XK8 Hydraulic leak - How to close rear quarter lights?



Gents,

My hood wouldnít raise and saw a green puddle by my rear right tyre.

In boot I found more green puddles under pump body.

Dark now, and am busy, so I turned off pump tap, raised hood manually and locked down latch using Allen key. Iíll investigate more at week end.

For now, how do I raise the rear quarter lights? No time now to strip quarter panel and just put 12V on regulator. Normally expect some fancy factory short cut used by fitters, ie press some buttons in weird combination

only 2 ways to raise them - make sure the rams are fully extended to engage the microswitch or remove relay and jumper

Default Leaking Hood pump body

Idea - possible quick way forward is to fill Hydraulic reservoir full and try switch to force hydraulic rams forward to click microswitch. Quarter windows should then switch and go up

The leak could be at the hoses to the rams on the other side of the pump. Looks like the hoses to the latch have been replaced.

Attached is a diagram of the linkage for the roof ram. My directions on this link is to unlock the roof rams but if you do the opposite of what it shows you can lock the rams. One thing you do not want to do is to force it in a way that will cause the roof linkage to bend. Not an easy task but it can be done in a pinch.

David - looks like the original hoses. Best to replace them with upgraded hoses from either Cabriolet Hydraulics (I used them) or Top Hydraulics (most forum members have ordered from here). Both companies offer high-quality, higher pressure rated hoses - full set for about $600. Top Hydraulics also offers rebuild services on the rams and pump if needed. Can be done as a DIY - takes about 8 hours

Hi, have your read my posting about the infamous green shower? Here you go https://www.jaguarforum.com/showthre...=1#post1094300

Hope it helps in some way but it looks like you have a different problem from normal deluge? It looks like your leak is from a pipe at the rear of the filler tank? I did not even know it had a pipe there! Good luck.

David,

First off ... since you do not want that pump to try to work while you have a broken hose ... I would disconnect the big 2-wire electrical connector to the pump. Also be sure the petcock on the pump is open when you're going to try to manipulate the top by hand.

If you have not gotten the rear windows to go up yet ...
Is the top up and latched? Only If so ... Turn ignition key to ON. Then press and hold the roof rocker switch in the UP direction. The windows may close. If not, press the rocker in the DOWN direction for a few seconds, then again press it in the UP direction. May work; may not.

Good luck.

Default Didnít work

Nope, tried that and didnít work.
Maybe thatíll be an electrical project for someone to fit a bypass switch to raise and lower the rear quarter windows. Difficult job to not disturb the hood electrics

Default Thatís so Cool! Rev Sam did it in 2011

Geez! Thanks for that. Rev Sam makes it so simple in the video.

Just oredered my replacement hoses. No problem at the moment as weather is good for a couple of months for top down driving in Bahrain. It doesnít rain much in the Arabian Gulf

Default Temp. Fixed loose connector - how to bleed air

Right! Got loose hose connection temporarily back in. Filled the tank, but thereís air in system as bubbles feed back to reservoir as I operate hood button. How do I bleed the system?

David, can you Google Jaguar TSB 501-33?

I couldn't find a copy to post, but its easy to read on line. This TSB details how to replace original fluid.

Let me continue your question since the TSB is focused on fluid and doesn't seem to say air: Forum - does one have to purge air the same way you purge old sticky fluid (disconnecting hose at header and purging)?

The system will self bleed the air out after a few operations. You just need to pay attention to the fluid level. As for your temporary repair remember that the pump puts out 1,600psi.

Default Temp. Repair is temporary

Thanks guys. I know the danger with hydraulics and be assured the temp repair is temporary. New hoses are on the way.

i just want to get rear quarter windows up now to stop Ginger, our next door neighbourís cat who likes our garage space.

Iím Considering a ďbodgeĒ job where I resort to Rev Samís splice on green wires in Centre console and ground.... but we all know these types of jobs never end well... Hmmmm

Default Right back to normal..... temporarily

Well, my initial idea worked.
When I fixed the leaking connector (using a pipe crimp), I then filled the reservoir and locked the petcock. I tried the hood a few times, and it moved out of synch so I stopped - I didn't push it. Bubbles in the reservoir fluid were a sign of air locked in the system. I didn't try it again as the motorised pump got really hot and battery died!

I drove the car a bit and the motion must have dislodged the air, and/or charged the battery up, as I when I tried the hood button again, the hood went smoothly up along with the rear quarter glass. Success.... for now, but I know my fix is only temporary and the new hoses are on the way.

At least the car cabin is closed now to stop Ginger, my next door neighbours cat ! Rain isn't a problem as it hardly rains in Bahrain, plus if someone steals a car in Bahrain, the criminal penalty is that they might get their hands cut off. That's justice!
