Question about 2004 Jaguar X-Type
After having the car serviced and having the fluid topped of the coolant light comes on in my 1998 Vanden Plas. I have had the car to the Jaguar Dealership three times and they are unable to resolve the problem. They have checked all wiring and sensor and now they believe it is a leak from the Radiator into the cyclinder head. If so, this should be causing a discoloration of the oil fromt he anti-freeze, but that is not occurring. Does anyone know what could possibly be causing the problem. Also the Dealership states it will cost $5,000 to replace the Cyclinder head gaskets to repair the coolant light problem and they keep saying the car is over heating, but I never see the temperature gauge go beyond half......Any help???
Also at the same time I drow the car for 800 miles for Michigan to South Carolina and had no steering problems, now since taking it to the Jagaur dealership the steering is getting tighter and the dealership states it will cost $2,000 to repair the steering.
I dont know if I can solve your problem but it sounds like air is trapped in your cooling system. The part where you lost your heat is an indicator of trapped air or a bad thermostat. Since your thermostat was replaced, I would try to purge the air from the system. I have no Jaguar experience but cooling is cooling. My 2000 buick has the same problem. I replaced the coolant level sensor and still the "low coolant level light" comes on at startup and stays on the whole time the car is running. I recently replaced the water pump and after that everything was fine. Added 50/50 dexcool to top up the system. Coolant level light started coming on during the winter. Checked coolant many many times. Alway full. The electronic troubleshooting check for the sensor is to unnplug the sensor and if the light goes out the sensor is bad. However my sensor is $55 worth of brand new. Not that a brand new part cant be bad, but its highly unlikely. Also two more things, check for a soft radiator hose or heater hose. They collapse sometimes under draw from the water pump,and the water pump may be sucking air through its gasket surface due to improper torque on its bolts, or a crumpled or misaligned gasket as it was being installed. (if it has one)

I recently (one week ago) had the same problem; the coolant low light kept coming on. There were no visible problems other than the light. Mine too did not overheat. I took it into the Jaguar dealership and was told that there was a leak in the thermostat housing. I took it to another reputable mechanic and was told the very same thing. The thermostat housing and hoses were replaced and no more light. Problem solved!

If you are having a low coolant warning light coming on, you either have a faulty sensor, or the coolant is escaping somewhere.
To diagnose the source of the loss of the coolant there are 2 procedures that must be carried out as follows......
1. The cooling system must be topped up, and pressure tested to max running pressure 15lb sq in.
If there is an external leak this will show it up, possibly from cooling or heater hose, water pump, radiator, or the heater matrix.
If nothing is apparent an internal leak, must be then suspected, ie head/s or head/s gaket/s.
2. To test out this , a carbon monoxide test should be carried out on the cooling system, by passing, a sample of the cooling system gas, when engine is at normal running temperature ,through the test fluid in the vacuum tester.
If the fluid changes color, this is proof the combustion chamber gases are escaping into the cooling system, which over pressurizes the system and normally blows the coolant out of the header tank overflow, as you drive along, and you do not see.
The other symptom of this problem, is the coolant leaks back into the combustion chambers, when the engine is switched off, and when you start later, a misfire is noticeable until the spark plug dries out.
This is quite a common problem, if the engine has ever been overheated at some time.
Have you had the vehicle from new, and can you confirm this is not the case ?
As For the steering problem..........
Seems V/strange you now have this problem appearing, after just visiting the Dealer ?
You firstly must check, if it is due to a loss of P/S fluid, by checking the level, and putting a sheet of cardboard under the car, this will pinpoint the area of the leak ( Red Fluid)
If no leaks are apparent possibly the pump or the steering rack are at fault.?
Without actually seeing the car, and from your short description of the problem, I possibly suspect the problem could lie, in the water pump department, which if leaking when you are driving, allows coolant to drip onto the power steering belt, and give you loss of drive to the pump, and therefore stiff steering.
Have the pressure test carried out and this will eliminate this source of the problem, then go to stage 2.
Give me feed back on what you think !
Good Luck !
A FixYa rating is all that I ask for, and would be appreciated... Thank you !
