Guys, i know the jury is usually hung on these matters but, is it safe to steam clean the 1.9 TD engine or does it cause a load of electrical problems? Mine is a mess on the block and underneath due to a leaking rocker gasket.
Also, what about the underneath of the car front and back? I dont want to knacker up anything
Be careful with a jetwasher on the radiator - it's very easy to distort and even rip out the thin fins between the water-tubes.

I would recommend jet washing the engine when it is cold, I don't like the idea of squirting cold water at a hot engine and also if the engine is hot it will evaporate the degreaser.
You can also use washing up liquid ....put some in an old tub of some sort & use an old paint brush to apply it to the thick muck...work it in well & it will loosen the thick stuff. Quite often you have to repeat the cleaning a couple of times to get the thick muck off.
Don't forget once you have finished cleaning the engine & it has dried off to go round & check all electrical connection are nice & dry, I usually put a drop of oil on each one to stop any corrosion.
Cheers.

I am not keen on pressure washers under the bonnet, never know if water is getting in where it should not. I like to be more selective with under bonnet cleaning. I use Autoglym's engine and machine cleaner and a small brush to loosen the stubborn stuff. I then rinse down with a slow running hose and finish off with a watering can filled with limescale free water. I collect the water from my dehumidifiers in a large butt and is ideal for this.

I threw caution to the wind and, with the engine stone cold, sprayed all the grime with a can of gunk. Then drove appx 2 miles to use petrol forecourt pressure rinse after leaving the suspension setting high and engine running. I did avoid spraying the electrical areas, at least with high pressure. I got several appreciative comments later about how clean it all looked - and it did! I wouldn't hesistate to do it again personally but it was a cheap car to be begin with.
