I had a big scare recently. I have yet to find out the proper way to clean under the hood. I did a light spray while washing it the other day and it threw every possible code and fault it could, it would start and die or not start at all, I finally thought it was good and dried and I took it to the gas station shut it off and filled it up, went to start it and it died. You could hear the ecu was shorting it was coming on and then shutting off, I swear the ecu is in the vehicle and has a fan. Haven't located it but you could hear and watch the gauges and a small computer fan [not the a/c fan] kick on. Eventually it sorted itself out and has been great ever since, THANK GOD.

 

Spray degreaser on rag, wipe small areas. Takes time, avoids codes, saves big $ if you damage something with water. Is this an LR3 with this problem or the old reliable D1? D1 could stand to have ECU sealed and weather proofed.

 

Just another reason not to buy a LR3.

 

bull****, its alot worse when you wash off a disco one or two.

The trick to washing any car is to wash it while its running. then water won't get into places its not suppose to be.

Trust me, had a brand new LR3 some idiotic cleaner washed with a fire hose and we had to let the damn thing dry before it would start and did I mention it was supposed to be delivered that morning. Tried everything and next morning it started after it dried out.

I have also seen toyotas, fords, bmws, and chevys do the same thing by idiotic cleaners who don't pay attention and leave the vehicle running.

Always always leave the vehicle running and then wash it off, you will be surprised how cleaner it is.

 

The trick of leaving it running prompts the water distribution technologist (hose man) to discontinue application of fluids - because the motor starts choking or quits....

 

Dude chill out, Spence knows I'm just giving him a hard time.

So you dont worry about spraying cold water onto a hot engine huh?
Must be all the plastic covers keep the engine from getting wet so it does not crack?
Or is there some trick I dont know about?

 

Uhhhhh, maybe true for a DI, but most definitely NOT true for a DII, I wash mine a couple times a year at the DIY car wash. You could take your DII motor into the bathtub if you wanted

Spencer - glad you LR3 is still kicking

 

Every time I was my truck I also wash under the hood, and i do it at the car was, very high preasure. I leave it running and drive off when im done, never had one problem.

 

It's hilarious to me that we're having a conversation about the finer points of washing a vehicles engine compartment.

THIS is what unites us, brothers, and separates us from the 99% of vehicle owners in the world.

Hilarious, and awesome.
