1991 Jaguar XJS Coupe from North America


I recently purchased a '91 XJS and love the way it drives and looks.

The main concern I have, at this point, is that there is a persistent water leak on the drivers side (front seat). I have read two other comments in this format regarding the identical problem, but have heard no feedback from others on how to rectify this problem. Currently trying a silicon sealant around the windshield gasket to make repairs and hopefully this will work. I would like to have other reader's input as well, in the event the sealant does not work.

Would you buy another car from this manufacturer? Don't Know

Water in the foot wells can be due to blocked air contioning drain tubes.

Look under the Scuttle vent grille - just in front of the screen. Corrosion & dedris can leek water behind the dash, which will find it's way into the footwells. Also check the vent tubes are clear.

I too have a 91 & love it. But these little niggles can spoil the fun (temporarily).

I also own a 1991 XJS and love it. The previous comments are accurate, but there is one other place to check. There is a drain tube that exits between the enging and firewall. If this tube is clogged, it will cause puddles also. The tube is easy to see when the car in on a rack for an oil change and/or lube. On my XJS, it was the windshield that leaked. I had it removed, resealed and reinstalled. The windshield had been previously replaced and it was done incorrectly. All is fine now.

Good Driving.

I have no XJS experience, but rebuilt an XKE over a five year period, and it had the same water leak problem --- on the driver's right foot.

After cleaning out the air conditioning drain line, the problem went away.

In the manuals that I have, it is a known issue with this body style. It also details how to resolve the problem.

I too have it, so I know what you're talking about. Check into what's new in an XJS and you'll find the fix.

Hello, I had just bought a 91 XJS, & had it out for a drive, & had noticed the same problem; it was raining & leaking from the passenger & driver's side windshield. I looked on the outside, & noticed that the curvature of the frame & glass at the bottom corner of windshield, the water was pooling. I am going to do the same, but before I do, could you let me know how you made out the silicone, & if it sealed? Thank you.

General Comments:

An absolutely beautiful car inside and out. Fantastic to drive. Unfortunately due to the petrol consumption and parts cost this is really just a car for the weekend.

Do not use dealerships they charge a lot of money and most of their mechanics have never worked on a car of this type. Find a local specialist!

A great car for £4000. I will buy another, and another, and another..


The heater matrix was on the way out and was leaking when I bought it. Heavy steaming and condensation in the car revealed this. This cost £900 to fix, but was covered under warranty.

Also a whining noise from the differential bearings revealed and almost seized differential. My garage reconditioned the differential and replaced the bearings. Cost was £1700.

The boot lamps remained on even though the boot was closed. This managed to drain my battery and caused me to buy a new one. Raising the boot close detect switch by a couple of washers solved the problem.

General Comments:

The car is a great drive and pulls away and kicks down superbly. The drivers position is a little cramped as I am 6ft 2. Boot has plenty of room.
