Thread: Washing TD6 engine bay

Michael, the ECU and important stuff is inside that Huge black box on the front right hand side, under the engine cover there is only the injector loom etc, as with any electricals they don't recommend getting them wet. ( might cause corrosion of the connectors?)
The Alternator is also supposed to be protected according to rave when you read the radiator drain procedures, make you wonder though, if water got splashed up from under neath from the road anyway.
Cheers, Mario

My advice is dont - if the L322 is anything like the RRS under the bonnet things are shielded from water coming up from the bottom bit not shielded form above - I have only washed my engine and this was with a hose and I had transmission issues for a week - including being stuck in low range because the relevant ECU is behind the battery and not shielded from water above and is not water prove.

A wipe down clean is probably the best.

I've washed the engine bay on mine several times without issue. As mentioned stay away from the ECU box. I've degreased and washed mine with the engine covers off - around the injectors and injector loom - no dramas.

Everything's pretty well sealed - it gets plenty wet enough driving normally in the rain - lift the bonnet one day after driving home in the pudding rain and you'll see.

They aren't that fragile.

Be very careful not to get the ABS computer wet it's on the back right hand side. As this is quite costly to replace and easily damaged by water!
