A good tip for your wheel bolts
A stuck wheel bolt is a real pain, especially if you have to change a wheel whilst out and about. It's the mating surface between the cone part of the bolts and the corresponding conical face in the alloys that causes the problem. Because the metals are different, aluminium and steel, galvanic corrosion can occur if any moisture gets between them. The corrodes the aluminium forming aluminium oxide which takes up more space than pure aluminium thus jamming the wheel bolt in position. This is how to ensure you don't get stuck by the side of the road:
[A] Remove each of the wheel bolts one at a time and carefully smear copper grease around the conical part. Don't get any on the threads as this can affect the torque value on the bolts when you refit them. Just snug up each bolt as you go and when you've done all sixteen, tighten the four bolts on each wheel in a diagonally opposite pattern to 77 ft/lbs of torque.

You shouldn't have any more problems removing a wheel from now on .
An essential tip for your rear number plate light
My car recently temporarily failed it's M.O.T because the rear number plate light wasn't working. The tester showed it to me and the inside was really corroded, the two pins in the bulb assembly has totally rotted off and were stuck in the contacts on the lighting loom! Luckily the nearest Nissan garage had a spare light assembly in stock so I flew over there and bagged it. I then shot off to the nearest Maplin and bought one of those tiny screwdriver sets and eventually managed to wangle the rotted off pins out, fit the new light and test it; it worked - YAAAY! This is how to avoid the whole unpleasant experience:
[A] Use a knife tip or flathead screwdriver on this plastic catch and the whole unit lifts out of the bumper. Unplug the connector.
[B] Give the loom connector a good scoosh with WD40 or electrical contact cleaner and lubricant.
[C] Give the pins in the light unit a good scoosh with WD40 or electrical contact cleaner and lubricant.

Repeat the process every six months or so and the job's a good 'un .
A ghetto fix for blocked disc retaining screw holes
I recently decided to fit disc retaining screws after finding that replacement screws were available from, ahem, Renault. The first one on each side went in perfectly but I noticed there were two screw holes on each wheel so bought two more screws. Weirdly, the remaining hole on each wheel was blocked; the screws would go halfway in and then creak to a halt. I didn't want to fork out for a proper tap so had a rummage in my dad's nuts and bolt drawer and found a stainless bolt with the same thread. I clamped it in the vice and used my angle grinder to grind a notch in the threads. I ran this into both holes going half turn in, quarter out, half turn in etc and they went right in with no issues. All the rust and crud was gone and the remaining screws went in perfectly (slathered in copper grease of course)!:
[A] Grind it so the trailing edge of the cut is parallel to the shank of the bolt and the curved side forms the cutting edge.
Making sure your bonnet doesn't get jammed closed.
I had a problem with my previous car, the 160SR, whereby the bonnet latch got so rusty the bonnet often jammed closed. A good tip if you've just acquired a K12 is to get a can of white lihium spray grease and give the bonnet mechanism a god slathering occasionally. it's also a good idea to give the door latches a squirt occasionally, too.
[A] Give it all a good coating of grease and make sure you do both sides.
Six sided sockets
This is a great tip! When you need to remove either really tight or really corroded bolts, ordinary 12 sided sockets will often round off the bolt head or just keep slipping off it. Six sided sockets will give a much more secure grip on 'dodgy' bolts or nuts. Every home mechanic should own a set; these are Blue Point sockets, the cheaper brand from Snap-On, and were invaluable for removing the intake manifold bolts on the 160SR.

Obtaining the correct front grille indicator bulbs
I went to a scrappy today to buy a pair of pre-facelift grilles for my car. They have amber indicator glass so I needed to buy a pair of clear 21W bulbs. I bought a normal pair and found they didn't fit... it turns out the pre-facelift K12 has a standard bulb but the facelift uses what's called a BAU15S based bulb. As the pic shows, the BAU15s has the pins offset so they're not opposite each other.
