My 91 v12 facelift coupe has the coolant light on and loses water to the garage floor.

I have been told that water is coming through the cylinder head studs and that it needs a cylinder head gasket. Its a 23k mile Japanese import and likely that its not had regular coolant checks, so it may have other issues. Could anyone recommend a suitable garage or specialist ? Many thanks

i have the same problem and the diagnosis was head gasket failure! trouble is if you do one bank you might as well do both to be safe, you might have to replace a few studs while there and have the heads skimmed, you wont regret it. as regard to a specialist where abouts are you! i know who can do this at good price.. tel 07973773979

  • Hi, I’m afraid this is a cry for help, a plea for some sanity. I have a (Once beautiful) 1994 XJS 4.0 coupé with an AJ6 engine. just over a year ago I thought something was up so I took it to a Mechanic who said that the Head Gasket was bringing to show signs of Failing. Great I said can you fix it? To which the Mechanic in question said yes. Fantastic I said so I left. Long story short, I found My once beautiful XJS languishing near a river after a year of hounding the mechanic. Last week finally took repossession of my car. The Head does now need doing and the brakes and cooling system. My question is this. Does anyone know a mechanic in the south hopefully near Brighton who could breath life back into the old girl. I would like it to not be left languishing outside again but be fixed and returned this time. Anyone know someone that knows these cars and is capable of doing the job?
  • Hello all I don’t own an xjs but an etype with an efi v12 in place. Need to remove all extraneous bits from an HE efi engine from an xjs now that is in an E type. It has already lost the A/c system and the emission control stuff but I’m still left with other bits and pieces variously attached with wires pipes and the like....any tips to find a good explanation of the position and function of these things, i‘m used to RR v12’s but not jaguar. peter.
  • Hi every one. I have a 1992 4L Facelift. Once the engine has reached 'working temperature', turned off and left for say 1 hour, on restart the engine the engine falters when moving off. I thought it was fuel starvation, but a new pump has not solved the problem. The car has had many sensors replaced. But, is there a sensor that controls a warm start up? Ant ideas welcomed. Cheers.
