I have a 2002 Jaguar x-type that overheated a little over a week ago. I was told it was due to the water pump and ended up having the water pump, tension pulley, radiator and thermostat housing replaced. Since then, it has started overheating again. I have noticed that is seems to only start overheating when the AC is on high. I live in AZ so it is pretty normal to run the AC on high, when I set the AC to auto.
If anyone can help, I would really appreciate it. I've spent $1000.00 on this car in the last week and it still overheats

thanks for any help or guidance from anyone who is familiar with this.

 

Welcome to the forum Julie,

I've copied this question from your Intro for advice from members with the same model.

Julie, I am not sure if you are going to like my answer or not, but most likely this is what is causing you issues.

The first thing I want you to do is to open the hood of your car the first thing in the morning (or whenever the motor is cold) and then start the engine with the A/C turned on to max fan and the lowest temp you can set the A/C to. Now, get out of the car and lean over the front of the car some so you can put your face in the air that the fans are giving off. Is it a gentle breeze or does is feel like you are in a hurricane? If you feel like it is a gentle breeze, then you most likely are suffering from a bad fan module (common issue with our cars). If it is feeling like a hurricane, then that is most likely caused by a blocked radiator. A coolant flush might help your situation, but can't make any promises.

Something else to consider. Does the overheating happen on the highway (ie, cruising at 60 mph or so) or when you are in town (down at 20 mph or so)? If it is happening on the highway, then this would point more towards a blocked radiator. If it is happening in town, then that would point more towards the fan module.

I know how hot it can get in Arizona. I was in Phoenix for a school and when I went to get into my rental car at 9 am, the temp gauge came off of C after the car had sat all night. It was a bit toasty, even at 9 am.

 

Julie,
another thing you could try is to clean your condenser coil.

 

Thank you Chris, i did that and there is very little air blowing out. Does that mean I need a new fan module?

 

Julie, yes it does. You are fine to drive on the highway, but when in town, drive with the windows down. The more heat you create (ie, with the A/C), the more likely you are to overheat the car.

Now, if you look at getting a new fan control module, you need to be aware of a key point. In mid 2004, Jaguar released a new fan module because they realized that the original one wasn't lasting all that well. So, they created a new module that is very similar in size, but the plugs are slightly different. So, if you are getting a used module, you need to make sure that it is able to be installed into the early X-Types. Your other option is to get the later style controller, but then you have to get an adapter harness (new is only available through the dealership, if you can find it used, I wish you luck) to go from your early module harness connector to the new style connector. It is like $100 at the dealership for just the cable.

If you have more questions, let me know. I will assist however I can.
