Hi,iv got 2002 jaguar s type r last week it started leaking engine cooling liquid from back of engine above gearbox i tried evrything to see where it was coming from but couldnt find out so i assumed it leaking from engine core plug so i put in radiator seal liquid. it stoped water leak but i am getting hot air in from the heater. its blowing in barely luke warm air its more on cold side than warm. it was all fine before cooling water leak, could be air lock inside heater system. please could some 1 help. thanks, m-tech-sport

the best way is to remove the front subframe and the complete engine and transmision as one unit, you have to support the engine/transmission unit on the subframe with wood blocks or similar whn you remove the engine/gearbox mounts and dismantle it on the floor, it is possible to remove the gearbox and leave the engine in place but it is not easy to remove the transfer gearbox for access, this is not a easy job to do unless you have access to a ramp and engine lifting gear, there also some special tools that may be needed to remove the drive shafts, i have done lots of these as i worked for a jaguar dealer for over 20 years you should try to get a workshop manual and follow the procedure in that, it is not really a diy job. hope this helps

change yor air flow sensor

Possible but not probable, Restricted converters will usually set a cat cod and check engine light will come on. I dont see a gearbox light on fault light on instrument panel

have to get leak fixed fault will show up every time fluid level is low -but trans-gearbox can overheat and burn up which will b more costly

What I do is park the car uphill. Let it cool, open the cap, start it, and let it warm up until coolant flows in the radiator. Add coolant and let the air burp out until there is good flow with no bubbles coming up.

was the prob a hole in the heater hose if there are any back tthere

The only thing that will cause a cruise control fault is a loose vacuum hose ussually on the breather hose coming from the valve cover in front to the throttle body. As for the remainder, shut off the car and restart to get you home and avoid the limp home mode. That in itself is an electronic fault in the ground system. Check you coils or replace them with a new set of plugs (autolite double platinum recommendes.) Clean any grounds you may have and then start you engine. You will notice there is no problem then. Run a diagnostic tool to see if there is any fault with grounded sensors like the O2 to keep that from happening again. Don't get the tranny replaced cause thats all the dealership wants to do and charge you $5k. Its not the actual cause. Good luck and let us know if there is anything else we can do here at fixya.

Hi .
unlikely to be immobiliser fault ,so check basics,try a set of jump leads or check battery voltage above 12.5,if the clicking is coming from the starter motor with a fully charged battery then suspect starter motor failure.

if the pump is leaking then it needs replacing it sounds like someone in the past has introduced glycol based coolant in to a oat. organic acid tech coolant system THEY DO NOT MIX and go like brown jelly and block things up like heater/ac systems it needs a good flush using a cooling system flushing adative

I have a 2002 X type (2 litre. done 44000 miles), dash showed gear box problem, (red circle light up). I pulled out and turned the engine off. 5 minutes later turned the engine on. The engine running but the car would not drive either in drive or reverse. Turned the engine off again and on the car driving but not much power. The care is taken to the Jag. dealer and told is misfiring + some gear box faults. Suggesting to change some coils and see (cost about £200+). also possible need to change the gear box costing about £2500+. Please advice. Shall I go ahead with the repair? Should I part exchange.
