Default Some X-type 2,5 v6 questions

Hello!
I recently puchased a X-type 2,5 v6 -02.
Its my first Jaguar and I am thrilled.

I do, however have some questions about some things.
First, is the car going to rev very high on low speeds?
For example, im doing 60 mph and it revs 2500rpm.
And it feels a bit sluggish when accelerating.

The second thing is, the handbrake seems to be a bit loose,
Ive read that it is supposed to have a self-tightening function.
Am I correct when I assume I just pull the lever till it works? =)

Have a nice day!

AB-x, you are pointing out the difference between the 2.5L engines and the 3.0L engine. Yes, the both use the same block and most of the parts are the same. But, the 2.5L engine has a shorter stroke length. So, this results in lower torque. Torque is what makes a car accelerate. Horsepower simply allows you to maintain a speed. The 2.5L car will pass a car with gusto if you let it downshift a gear or two. The 2.5L motor will make lots of power if you get the engine RPMs up in the 4-5,000 RPM range. Where, a 3.0L engine will remain in gear and just accelerate (due to the extra torque it makes).

As for the e-brake, I would be looking at your e-brake levers. I bet you will find that one or two of them are frozen. If this is the case, you will need a new caliper. This is a common problem with the X-Type. You are correct in that pulling the e-brake lever should tighten up the cable. But, if you have other issues (ie, frozen e-brke lever), it may or may not tighten up. You can check this by simply getting the rear tires off of the ground and then setting the e-brake. If you can turn the wheel a little bit, the e-brake is not engaging. If the wheel is rock solid, the e-brake engaged. I used to have to replace a caliper per year when I had my X-Type.

If you need more info, let me know.

Great answer Thermo!
You have given me a better understanding of how it works, thank you!

I was suspecting that it was something like that.

Regarding the brakes, i figured i needed to change something, since i got the car kinda cheap.

I turned over my car to a carcontroller yesterday.
Seemed good except for some rust and an errorcode P0158.
But the Check engine lamp is not lit.
So i dont know.

Anyways, thank you for your answer!

AB-x, if you need to know anything about the brakes, let me know. I have dove into them quite a bit and have a few posts here that may help you.

As for the error code, it is probably something that the car had in the past, but was repaired. The person that fixed the problem did not clear the codes. So, should the CEL come on, you will need to ignore that code unless that is the only code that you get.

Thermo: In prior posts, someone said the key difference between 2.5L and 3.0L engines is larger bore and larger diameter pistons in the 3.0L, hence more power & torque. So I checked the shop manual: 3.0L bore is 89mm, 2.5L bore is 81.6mm (~8% smaller diameter). The stroke is the same: 79.5mm in both. Live & learn.

AB-x: After a drive, are the rear calibers much hotter than the front? If 'yes', Thermo's correct: one or both e-brakes may be stuck, either because the cable is stuck, or the e-brake levers on the rear calipers need some grease, common issues with our X-Types.

The 2 posts below have pictures and instructions how to unstick and grease the e-brake levers without removing the rear calibers from the car - a shortcut from Thermo's more detailed posts on disassembling and rebuilding the e-brake calipers.

dwclapp, I was pretty sure that the X-Type had the same bore in both the 2.5L and 3.0L engines since they used the same block. Making the only difference the stroke length. Guess I need to get a few X-Types in my driveway again and get back up to speed with repairs. Getting spoiled with my XJ. He he he he.

AB-x: Today I paid more attention to my X-Type's rpm at different highway speeds, on flat land, with little /no wind, and the AC on. It's a 2002 2.5L petrol with 143K miles.

At 60 mph, the rpm was 2.1K in 5th gear. I slowed to 50 mph and the rpm dropped to 1.7K, still in 5th gear. I downshifted to 4th gear and the rpm picked up to 2.4K, still at 50 mph.

So 2.5K rpm at 60 mph in your 2.5L X-Type is too high.

My X-Type shifts from 4th gear to 5th at 40 mph while gently accelerating on flat land. If your e-brakes are dragging, I'm going to guess that your X-Type must get up to a speed faster than 40 mph before it upshifts to 5th gear.

Sorry for the late reply.
Long days at the office.

Great answers guys.
Really appreciate the responses.
dwclapp: I will check on the brakes, Im doing some maint. on the car tomorrow, cleaning sensors and changing filters and stuff like that.
If it does not work, Thermos complete rebuild of the brakes is next!

Thermo: I'll leave the wierd code for now! Thanks man!
Dell Gaily: wth is a ***rasberry***?

Have a great day and thanks for helping out!
Cant contribute with much knowledge about cars, but if anyone has a question about printers or printing software, Im your guy!

AB-x, have you ever taken a little kid and blown on their stomach, buzzing your lips at the same time, to listen to them giggle. Some would call that a raspberry. Some may even look at if you were to stick out your tongue and then blow to make your lips buzz around your tongue (like you see in the cartoons), some call that a raspberry. It is a way of showing that they got one on the Thermo. Gotta take the good with the bad.

Lol, yeah it was @ Thermo rubbing in his newer XJ. We're a good lot here.
