Hello all Does anyone know if it is possible to remove the left bank (2, 4, 6, 8) cylinder head with engine in car? The official way is to drop the front and rear subframes and work on the exposed engine, there is no mention of in-situ, even though there is a special tool to hold the timing...

'Morning all Has anyone found a means to test the coolant pressure cap? Yes ok, I could buy a new one. However, if there is a straight forward way to test the cap is keeping the pressure below one bar, I am interested to know how it was done. TIA

Hello all My X has been suffering a very, very slow drop in coolant level (over 18 months a cup or three), which until recently I convinced myself was simply air purging out after a coolant replacement. Sadly it is an actual leak, though very slight. I have found the leak's source, it is near...

My X developed a very modest and occasional slight 'sneeze' or delicate 'cough', while idling waiting at lights. In park there was nothing to notice and when moving, again nothing to notice. However, not right. I plugged in the Tech II and it has a diagnostic function that displays a mis-fire...

Hello all Well, sooner or later the OEM Satnav will show its age and in my X, it is taking 2-3 mins before it can read the nav DVD, then it mostly works fine but sometimes takes a long time with directions. So, I am considering options to replace the entire unit. What are the best options out...

Hello all I was planning on re-programming the (new) TPMs on my 2004 X but have gotten stuck. I go into Accessory mode fine and press both buttons on the remote. After 3-4 seconds a get a single chirp, I'm expecting a double chirp. So far I haven't managed to get a new sensor recognized...

Hello all I've read many (all?) of the posts on changing the shocks and am left with a bunch of small questions, if anyone can oblige: 1/ Where is the electrical connector on the front shocks? 2/ How do you get the top off the shock? Is it necessary to use circlip pliers to squeeze the...

'Morning all I note that OPG are carrying XLR parts now (see Cadillac XLR Parts @ OPGI.com) A quick scan over their site suggests that currently they are only carrying GM parts available elsewhere, and judging by their prices, they are not yet the cheapest out there either. Anyways, does...

This had me puzzled at first. I found a small amount of strange goop in the middle of the roof seal, at the top of the windshield. Not grease, more like paint to remove. Very, very sticky. On the underside of the front of the roof there was more of it. There is no place in the roof it can...

Does anyone know for certain what the thread form is on the nipple connecting the brake line to the flex hose for a 2004 XLR? I have a new Delco flex hose and it will not fit on the nut. I have bought a replacement nipple which states it is 10mm x 1mm and that will not fit into the new flex...

Hi all I have been asked to help with setting up the distributor angle on a 1995 GMC (might be Chevy) Day van. It is the design where there is a big disk being used to measure crank (or cam) angle as part of the distributor. I don't know much about it but as I have a Tech-2 I have been asked...

Looking at a vehicle with a no crank condition recently, I was interested to see that the root cause was a seized a/c compressor which had also jammed the clutch closed. As a result the starter was not able to crank the engine, hence the no crank condition. The solution is fix the a/c...

I recently had the joy of erratic start and or erratic can't get out of park. Diagnosis is defective brake pedal position sensor. As a clue, while I was starting to investigate I had accessory mode on and the brake lights were flashing on and off slowly. I was standing outside my XLR. So, to...

I have never had this happen before. On Tuesday, I noticed a curious tar like mark on an old bit of carpet (not in my XLR). I didn't have the time to investigate properly, but it was a tar like substance, on touching it, it left a black gooey smear, was about 4" long, 1/2" wide and appeared to...

Hello all I have lurked on here for too long and the time has come to join. Having been a member of another XLR list for a good while (ahem), it seems the time is right to join here properly.
