Re: 1997 Jaguar XK8 cooling system
The radiator drain is on the right lower corner of the radiator (passenger)
You can use a wide flat blade screwdriver to unscrew it.
Is is held in by a piece of plastic so you don't have to worry about losing it when draining. just loosen it and leave it there.

None. Open the petcock on the radiator to drain the cooling system into a drain pan. Close the petcock, remove the clamps that hold the lower radiator hose to the radiator and the water pump. Remove the hose, install the new one, install the clamps, fill the cooling system, and you're done. With the radiator cap off, run the vehicle with the heat on until the engine gets up to operating temperature, allowing the thermostat to open, to allow you to be able to completely fill the system. Install the cap and you are done.
either your "double-crossover flow" radiator is plugged or if you have excessive pressure when you remove radiator cap its got a bad head gasket,then start checking your oil for signs of milky looking oil and foaminess then you got BIG troubles ahead
I'm not familiar with the jag but my ford is similar( no dipstick). I'm led to believe these are designed to prevent overfilling, which can blow out the seals. I undo the top pipe which goes to my radiator to cool the trany fluid, then get a 1/2 metre length of plastic tube to fit between the disconnected pipe and a 1 litre bottle of fluid. I then squeeze the fluid in that way....no more than a litre at a time, then try driving it again..Hope this helps.
I'm sure you mean Volts not amps. That ALT. has an internal voltage regulator when they get hot they are known to fail to be sure have the carging system at a garage it runs about $50.00 but better than buying an alternator that may not be broken.
the transmission gets cooled off with the radiator if transmission oil is getting in your radiator then the tank that is inside the radiator is cracked you need to replace it or the whole radiator and flush out the engine to get out all the trans. fluid out of the cooling system I hope this information is useful good luck
check your lock relays located in the interior fuse panel. Sometimes the actual connections to the fuse block can come lose and the relays wont work properly. My 2000 silverado did the same thing till i bent the pins on the relay for a tighter fit.
hope this helps
Cooling System Ensure that the engine is completely cool prior to starting this service.
1. Remove the recovery tank or radiator cap.
2. Raise and support the vehicle.
3. Place a drain pan of sufficient capacity under the radiator and open the petcock (drain) on the radiator.
èPlastic petcocks easily bind. Before opening a plastic radiator petcock, spray it with some penetrating lubricant.
4. Drain the cooling system completely.
5. Close the petcock.
6. Remove the drain pan.
7. Lower the vehicle.
8. Determine the capacity of the cooling system, then property refill the system with a 50/50 mixture of fresh coolant and distilled water.
9. Leave the recovery tank or radiator cap off to aid in bleeding the system.
10. Start the engine and allow it to idle until the thermostat opens (the upper radiator hose will become hot). The coolant level should go down, this is normal as the system bleeds the air pockets out of the system.
11. Refill the system with coolant to the proper level.
12. Turn the engineOFFand check for leaks.
I think the spares situation for Jaguars, is disgusting with the main dealers.
I have been trying to source them myself, for about 2 weeks, and only found ****, painted up second hand ones.
I will keep trying, and let you know if I am lucky and find a source for genuine new springs.
