Jaguar 1998 XJ8 Vanden Plas Questions & Answers
My 98 jaguar vanden plas starts but the shuts off.What could it be?
I have a suggestion for you to pursue.
This is not specific to your Jag, but any car with the
symptoms you described. When the engine starts it needs
the battery to crank the starter motor and to power the ignition system. Once it's running, the alternator provides
the power to run everything. If the battery is weak and
only good enough to get things started, but the alternator
is not powering the system, the weak battery dies within
seconds as the ignition system drains it down.
( Thus - the ignition dies.) Put a volt meter across your
battery terminals while cranking & with engine running.
If it doesn't read over 12 volts ( engine running ) you
might look into a charging system problem!
That would also explain the weak battery - no charging.
Otherwise, suspect a bad fuel pump. I've had new
replacements fail on me right away. Some auto parts
are just poor quality and don't last. How to know?

Hello. The car is getting to be warmer then normal. The termastate could be getting bad and the water pump also could be getting bad. Better be safe then sorry, have some one check them out before big bad problems happen. Good Luck.
Coolant coming out randomly
Apparently you have a leak, but failed to disclose where. An internal leak would come out of the exhaust pipe and would be white smoke.
Hi my jaguar x type
Just two things without equipment. (That I know of). Is the clutch pulled in and the compressor running? If so, is the larger line coming from it cold? DON'T touch the small one! It could be very hot. If the clutch is not engaged, follow the larger tube from the compressor toward the fire wall. There is a low pressure safety switch that could be bad and can easily be by passed to check. Unplug the two wire connector and jumper those two wires. Be sure the AC control is set to "MAX COOL" and your thermostat is as low as it will go. Let me know if the clutch is engaged or the compressor running. You could have a 12 volt compressor with no clutch. They are out there. Roger
I have Jaguar S-Type 2000,
If it is low on Refrigerant, it will cycle the clutch off. When the pressure rises from the lines equalizing, it will come back on. When it does stay running, does the larger line get cold? If not, it is probably low on refrigerant. Roger
My car ac is not
Hi,
There is air trapped on refrigerant line. Please release it and add refrigerant and retry.Check also recommended refrigerant for your air conditioning system.
Regards, Jay
I have a 2002 xj8
If it only happens when the ac is on maybe it doesn't have as much power as before? Bad batt or possibly a bad alternator. Also check for a good seal on the intake for the air.Also check the IAC valve on throttle body.Also check if fuel injectors are cracked or got clogged.If yes? Clean the injectors and check.Also it sounds like a coil pack is on the verge of dying. The a/c is putting more load on ignition and it can't keep up.And this is causing the problem.
---------
But if all checked ok then it can be anything from a recharge (which indicates a leak) to from compressor.Or its weak compressor.--------------
Get this possibilities checked.This will point towards the faulty part causing this issue.-------This should help.Thanks.Helpmech.
Needs freon and I can't find the blue hose to put
Most air conditioners require a calibrated heated charging cylinder to add a charge, which should only be done by someone who is certified to do it, and has the proper equipment. Sorry, but this is NOT a do it yourself job.
