Default Water got under hood(bonnet).

So living on the WET COAST of Canada , it rained hard.

water has collected on the right hand side of car in this covered box. and wires are submerged in about an inch of water.


Do I dare start it?
Is there a drain?
Any advice would be GREAT!

Many thanks,
Andy

It would probably be very wise to remove the cover and drain the water before attempting to run the vehicle. Use a heat gun on low setting, or a hair dryer to remove the remaining moisture.

There is a drain in the cowl that connects to a drain tube to remove water. Drain may be clogged or the tube clogged or dislodged.

Often a stiff wire will open the drain. It's in the forward corner that's lowest (obviously).

Thanks everybody!


Got the turkey baster and sucked water out.

then found the hose was dislodged... there is a small rubber tab that keeps the cowl drain hose up and it was off the little hook see red circle

So I then removed the cover ( blue tick) of the ECU four screws... so I could refit the drain hose... be careful with the screws as you will not get tem back if they drop....they are magnetic too ....just in case

put it all back then got a wire and poked around at the bottom (yellow arrow) and the last of the water drained out.

Got out compresser and blew the water drops then heat gun on low to dry.

I think I will wait until tommorrow to start it

Thanks again for the tips

Cheers,
Andy

Sage advice for phones that have fallen in the toilet is to submerge them in raw rice... I'm not sure you could do that with the ECU, but if you were somehow able to remove it, and dunk it in rice for a few days you would have a higher chance of not having any problems. Has the battery been disconnected during this entire ordeal?

The ECU was probably not submerged, but the cooling fan under it may have been. The fan comes on with the ignition so that's easy to check. If you remove the ECU disconnect the negative cable from the battery and touch it to the positive post for a few seconds to discharge the capacitors before disconnecting the ECU. You can then open the case and check for moisture.

The ECU had no sign of water when I removed the cover....LUCKY... I think

Battery was conected... so I will check the fan under ECU before I try to start the car

Cheers,
Andy
