Nissan Leaf 2015 S - general maintenance

This article shows tips for maintenance of various car parts: replacing windshield wipers, spare lug nuts, how to jack the car, etc.

Spare wheel lug nuts

Long story short - after much searching I’ve finally found out that Nissan Leaf 2015 uses M12 1,25 lug nuts; you can buy spare for example from Biltema: Wheel Nut Kit M12 x 1,25, 35mm, Art. 33-3305.

Note that the replacement lug nuts only work with the steel rims originally bundled with the car; if you bought aluminium or other custom rims you need to shop there for spare lug nuts.

Tightening the lug nuts

The tightening torque is 112 NM; I recommend getting a proper torque spanner such as Momenttiavain 40-210 NM. The socket size is 21”.

Jacking

Nissan Leaf’s underbody is not flat but instead there is a pinch rail or a pinch weld; this nissan leaf jack video contains more information.

What’s totally weird is that I’ve failed to buy pinch rail jack adapter in Finland. The Nissan dealership, Motonet and also Fixus simply told me that it’s not being sold in Finland, and that I should simply jack the car and risk twisting of the pinch rail. Probably everyone simply uses a hockey puck or similar. The best thing might be to order a pinch rail jack adapter from AliExpress or Amazon and have it delivered to Finland, but that could be rather expensive.

I tried to order something from AliExpress, but the rubber is not strong enough: it twists and bends almost to the point of the car falling off the jack stand.

I ultimately purchased Biltema’s Jack Pad and a couple of hockey pucks - looks to be working the best.

Windshield wiper replacement

Where to buy them:

  • Biltema: Nissan Leaf Wiper Blades but they’re frequently out-of-stock
  • Motonet stacks the good quality Bosch wipers - I recommend shopping for windshield wipers there.

I’ve discovered the wiper exact part types via Bosch Wiper Blade finder which will find AR26U and AR16U exactly as above. You need to put Nissan Leaf 2018 there since the page doesn’t seem to recognize Leaf 2015 anymore.

  • The AR stands for “AEROTWIN Upgrade” whatever that is,
  • The U stands probably for Hybrid, or god knows what.

12V battery

Check out this youtube video on replacing the 12v battery in nissan leaf 2014, and also Why 12-Volt Batteries in Electric Cars Get Sick.

US-made Nissan Leaf 2015 battery group is 51R; the dimensions should be 238 x 129 x 223 mm; the terminal connector diameter is 17mm. Make sure to pay attention to R which says that the positive terminal is to the right. (measured on my leaf: W=230mm, D=123mm, H=200mm, height including the terminal connectors = 220mm).

The battery CCA is 410 which gives the Ah rating of ~38 according to BatteryEquivalents Group 51 and 51R and 360 EN according to CCA->EN Table.

In Finland here are proper replacements for the battery:

I’ve bought the “Sznajder Silver” battery from Motonet and it’s working well.

Beware: Nissan Leaf only charges its 12V battery when:

  • It’s powered on and there’s 14V coming from the traction battery,
  • Or when the traction battery is being charged.

Therefore, the 12V battery will NOT be charged when Leaf is:

  • powered off with charging cable unplugged, or
  • Leaf is done charging and is not charging anymore (e.g. after it charged its main traction battery to 100%)

Therefore, when you leave your Leaf charging for a month in a cold weather, it’s possible to find the car with a dead 12V battery even though Leaf was connected to the charger for the whole time.
