Jet Wash + Engine Bay
Ben_Copeland - 14/2/10 at 07:44 PM

One of my neighbours was washing his car today, i happened to look over to see him jetwashing his brand new Toyota engine bay! Didn't seem to be trying to avoid any electrics, just randomly and for sometime washing.

What's the bets it doesn't start in the morning?

Surely it can't be good to JetWash an engine, I was always told it was bad.

I used to do it in Greece on our Pick up Truck and our Renault 21.

Everytime there was an issu because of water. Wasn't the end of the world just some difficulty when trying to switch on the engine. Gave it a couple of tries and off it used to go.

Eventually, every time i used to pressure wash it, i tried avoiding the distributor cap and the engine was allways running.

Never had an issue after that.

New cars, i have never done it as i know that it can become a dissaster.

Well his engine definately wasn't running and must of been there nearly 5 mins

It'll be fine. If it's a petrol and the ignition gets damp it'll struggle to start and run.
If a diseasel then no prob.

Think of unfaired motorbikes ridden in the rain.

Plus, every new car have waterproof connectors.

I wouldn't worry that much but wouldn't try it to my car which needs it just in case.

You gotta wonder WHY he was doing in.
If its a new engine then it shouldn't be dirty.
If its a new engine and it IS dirty, then he's got a bad oil leak.
If it is a new engine, it IS dirty and he has an oil leak then using water on it is no use without a detergent.

So, my conclusion is, he's a numpty

I've always done it with the tin tops and occasionaly with the Indyblade
As long as you avoid the highesst pressure into the most sensitive bits it will be fine if built properly

I power washed the 'inside' of a Vectra, which I needed shot of quick.

Even the central locking started to work afterwards

I wouldn't either. Waterproof connectors are probably actually "splashproof" and even if they're better and proof against jets of water, that'll be against hosing down, not pressure washing!

Could he have been steam cleaning rather than jet washing his engine bay? From a distance they'd probably look like similar processes.......

Being a new Toyota he will be happy the car wont start in the morning, odds are it has every chance of not stopping.

had he been for a drive beforehand? If the engine was warm then he runs the risk of cracking the exhaust manifold...


Ben_Copeland - 15/2/10 at 07:36 AM

Yeah it was steaming as the engine was still hot

Dream on , I would like a pound for every time I have had problems with engine electrics a few months after the engine has been steam cleaned or pressure washed. Engine may start easily after cleaning but a few months down the the connectors will probably be corroded.
