Re: Corrosion Control - Rust Proofing a 2018 Nissan LEAF SL

Thanks Knight. The tail lights on the 2018 SL look to be standard bulbs for turn and reverse, but are LED for running and likely stop. There is one LED driver connection under what looks like a bulb port at the centre of the lens. I have the 12 volt battery disconnected but will confirm later. The tail light lens is about 30 seconds to remove ..just remove the two 10mm bolts, and gently shove the entire lens rearward to slide it free of the body clips.

On that panel, it's just a few bolts and clips, so would be very easy to drop. I figure that is the most effective way to clean it every 3-4 years of ownership. The car lived mostly on pavement (driving school car) so what you see in that panel is likely a lot of road sand. If you fire water in there, you'd likely just wash the sand/gravel further along the belly pan. There's also the high voltage battery connections a bit ahead of the panel, so I'd avoid water there :-)

You'll likely break some clips, but I ordered a replacement ( bag of 100 via amazon ($16) ) that were inexpensive and seem good quality. A few of these 8mm clips (spares if you brake a clip) and a 10mm socket is all you need to pull all five belly panels. The clip OEM part number is 01553-09321.

Btw a new front belly pan is $240 CAD from the dealer..so I'll fix mine. It's worth about $20 in my opinion :-)

Thanks for the link on the clips, it's a much better deal than the local auto store and I end up using a lot of those when doing stuff for friends, so a bag of 100 is awesome!

Great! Time to order some new bulbs, can't wait to have reverse lights bright enough to make it look like day time (like I had before, LOL) and turn signals so bright, you can see the reflection around the entire intersection at night :lol: You can tell, I like to be safe when driving at night, especially when backing up!

Knight, I figure a lot of margin is generated by body clips at the dealer and parts stores.

Post your LED bulb specs :-) Does the LEAF handle the LED bulbs without spitting any codes?

It worked fine for my 2013, the secret was the bulb had to use enough power to avoid any codes or make the blinkers go fast (like a bulb was burned out), but I will have to hunt down (dig through years of e-mail) those bulbs I bought nearly a decade ago. I have a 2020 now :(

They make special LED bulbs that have resistors to simulate the load of an incandescent bulb in the car...look for a CAN bus LED...here is a good place to shop https://www.superbrightleds.com/cat/led ... ,116,4017:

You just saved me looking for the site when I looked at it, was the same place I found my original LED replacements! :D

More work on the LeAF today, including servicing the brakes (one caliper pin stuck after just 3 yrs!), changing the final drive oil, finalizing the trailer hitch wiring, and removing the rear fender liners.

The front chassis shield needed some repair so I did this with some 6oz glass cloth and West System Epoxy

The rear shield corner needed fixing up. This is before grinding to shape after curing.
Image

The front shield needed 5 small repairs.
Image

Rebuilt the entire (missing) corner on the engine chassis shield.
Image

The LEAF has all of 5 shields to protect the underbody and improve aerodynamics. I gave them a quick wash..
Image

I used a drain port in the hatch floor to run power to the trailer harness, and run the trailer wiring out to the hitch. A fused 12V power lead had to be run all the way up to the 12V battery in the engine bay.
Image

This stuff is super handy for sealing up grommets among other things...

Looking up in the rear fender with the liner removed:

Thanks for all the great pictures and information! Yes, I love the liquid electrical tape, that stuff is so handy! :mrgreen:

Knight, you’re welcome. More pics to come.

Gravel/sand removal is going to be tough. The only place that a hose might work is a gentle stream run from front to back via the air vents on the rear shield. Sand was piled up in there, but there are drain holes. If you run water there the sand can’t migrate...it can only be carried out the drain holes. I’d also run a hose into the rear chamber in the mud guards for a minute or two each.. These were packed with sand as well. This LEAF has about 60 000 kms (36K miles) and has pretty much been only city driven, so someone on dirt roads will be worse.

The model3 chassis shields are worse..I’ve seen a few pics.
