Engine Cool Down

[tamborine]

Only went 10miles and it took 15mins for the engine to cool AFTER I removed the ign key - why ?

Provided your radiator levels are good and the temperature gauge showed normal levels, nothing to worry about. Water takes time to cool down.

On a run of 10 miles your car probably reached full normal working temperature.

What do you mean by cool - cool to touch or not registering on the temperature gauge, there's quite a difference. Cool to touch means around 40 deg, whilst the temperature gauge probably only starts to show at about 90 deg or more.
After 10 miles the engine and gearbox have probably reached full operating temperature - the engine normally takes 2 or 3 miles, the gearbox a bit longer. The engine compartment on most modern cars is well insulated due to it being soundproofed so, when you turn off the engine there is a large mass of metal to cool sitting in a fairly well insulated box. With no movement of the car there is no air flow so cooling will take a fair while as there's nowhere for the heat to go.

Thats normal

the engine kept wirring noise after key was removed

By 'wirring noise' I expect you mean radiator fan noise. Can be quite normal as some fans continue for a short while to bring temperature down, even after you've switched off. Easily checked by opening bonnet and visually looking.

If, as above, you're saying that the radiator fan was going for 15 minutes after you switched off...that's an awfully long time, and I can't believe it's normal for any car.
Even if the engine has become very hot (and perhaps has been idling for several minutes before you switch off), the fan normally runs for less than a minute in my experience.

I had to use a claw hammer to remove screw top of engine coolant (no strong men) & filled the container. Amaaaaaazing, purring engine & heater works. Rats have eaten bonnet felt lining but they also need the luxury of a Jag ;)
