[xj-s] cooling system crud

a numver of years ago i had a diferent car that a leaky freeze plug so
i went to replace it and i found a lot of crud and rust in the bottom of
the engine so decided to clean out the engine the best way that was
possible so i pulled all freeze plugs and used a steam cleaner to flush
all the crud out of the engine when i did my employer was not too happy
because i made a total mess of the service area so remember to try and
keep the cooling system of your jag up to service specs because that
crud builds up in all cars and you dont have the ability to do as i did
to this car
