    Cyliner head removal 2004 4.6

    Micky Once again, you are a mine of useful information. Agree, a useful test would be to get an airline and hold pressure for an extended period on #8. Monitor coolant levels. The carbon monoxide test came up with an easy pass. Ok, run hot. Yes, this might be the history. Unknown to me...

    Cyliner head removal 2004 4.6

    Thanks Micky Your suggestion re re-torquing the head bolts: Is that a generic suggestion or have you known that work on a N* motor? All excellent advice. I can rule out: plugs, coil packs and injectors. And fuel pump!. The misfire is for a max of 10 seconds on cold start. Long enough to...

    replaced battery now car will not start

    The ignition switches do fail. Pressing the bottom half of the switch and get a crank and engine start is indicative of multiple problems. Suggest replace ignition switch. Do a search here, the topic came up moderately recently. The brake switch is more complex than you might expect and has...

    replaced battery now car will not start

    Assuming the key fobs were working until you changed the key fob battery, make sure you put the key fob battery in the right way up. Make sure the key fob batteries are very clean and the contacts are also clean. Do you have a VOM? Make sure the key fob new batteries are working. It sometimes...

    Cyliner head removal 2004 4.6

    Thanks for the advice both Ruby and Micky. The question remains though. I have an excellent relationship with my Cadillac dealer who know this car well (and like it a lot!). We are all scratching our heads over what is wrong, with the view that although the head gasket is passing all the...

    Cyliner head removal 2004 4.6

    Agreed. There are no signs of problems with any of the spark plugs. Oil and sump good. Oil filler cap also good. No smell of coolant in exhaust. Car is early 2004. Year is in title of this posting. Water pump was replaced. Can't find any evidence of leaking from any external source...

    Cyliner head removal 2004 4.6

    This is very useful information, thanks. The pressure test has been repeated with engine hot and once again it passes easily. However, compared to cold engine, the pressure did drop about the width of the pointer (ie hardly anything at all) in about 80 seconds, compared to over three minutes...

    Cyliner head removal 2004 4.6

    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...

    Testing the radiator (header tank) cap

    '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

    Electrical Dead Short

    In my official two volume set, the wiring diagrams are embedded throughout the two volumes, there isn't a single section of wiring diagrams. The two volume set I have is very comprehensive, however each of the two volumes has far too many pages and they are falling apart. It makes sense to me...

    Can anyone ID this wheel?

    You might have to contact them, wheels change design very quickly, so now discontinued? Or else it is a DUB center cap and not a DUB wheel, always possible.

    2008 XLR Neither door will open from inside or outside?

    Got it thank you Micky. On the inside side of both left and right hinges. I was looking for a variable length adjuster, not an absolute stop as a bolt head. Vital for those both to be in place when the hydraulics are lifting the deck lid! Thanks again.

    Help! battery disconnected can't get in car

    Thats great news. Can I ask a few questions? 1/ How much force did you need to apply to lift the trunk deck lid? 2/ How slowly do you lift up? Is it easy to control the lift speed? Do you get a sense that you are damaging the hydraulics in any way? How long did it take (a few seconds or...

    Help! battery disconnected can't get in car

    This: https://www.xlr-net.com/forums/threads/how-to-get-into-your-xlr-with-a-dead-battery-and-no-emergency-key.6315/ However DO NOT use a battery charger to attempt to apply power. Because your battery is disconnected, you risk frying all the electronics. Use a stable 12v supply, and this is...

    Help! battery disconnected can't get in car

    IF you had a working main battery (and you don't), turning the key in the rear bumper also activates the hydraulic pump and lifts the trunk deck for you. But you don't. The 'turn the key in the rear bumper' is also a mechanical release of the latch holding the trunk lid securely closed. So...
