Replacing coil packs, DIY or not?

Got some new coil packs and spark plugs. Is this fairly easy to do or am I best taking it round to Whifbitz? I’m not too bad with a spanner but if the inlet has to come off or something then I can’t be bothered to spend hours on it lol. Will probably take Darren about half an hour so won’t cost much.

Any advice?

10 min job to get to them, just plastic cover off, unplug the loom, 6xbolts and there you go pull them out. small philips screws hold them to the brackets.

Brilliant, thought it would be simple [emoji106]

Its an easy DIY job.

Before you get stuck in though its best to check your coil clip and loom clip condition when you get the cover off. If they are original you will probably find yourself ordering in replacement coil clips and loom clips ahead of tackling the job as they will likely crumble. If the clips do start to disintegrate on you fill the recesses as far as possible with paper or cotton wool as any plastic fragments will fall into the spark plug recess and from there, if not extracted, they can easily fall into the cylinders once the plugs are removed.

If you do need to replace the coil clips its a relatively easy task, just can a bit fiddly to extract the wires from the old clips. There are tube videos that go over how to take the clips apart and withdraw the terminals. You can buy clips cheaply off eBay or not so cheaply from Toyota. The loom clips took 10 weeks to arrive from Toyota but there are generic post clips you can get again off eBay.

Yeah you really cant go far wrong, all Id maybe advice if a bit on penetrating fluid and heat on the screws if needed as they have a tendency to round off. but be gentle and you should be fine, the good thing is you can also get to the rear of the screw so if needed a small set of pliers on the rear and a bit of a wiggle should do the trick

Do you need to remove the breather pipes to get the packs out? as they can be hard as nails and split if old.

Yes I believe they are in the way. I gave my screws holding the coils a tap with a parallel punch and hammer and tapped the screw driver in with firm pressure it turned. I had to do this to 4 screws as they were getting damaged and would not come loose.

Cheers guys. Will look at getting the clips and maybe hoses too. Has anyone got a link to an eBay listing for what I will need please?

Coil clips, just find 6 of somewhere.

For the two breather tubes you may as well ask TCB. For the number 7 loom clips you can get those via TCB to. Just be prepared to wait a little while for the clips to come over from Japan.

PS - when changing coil clips its essential you put the terminal back into the same position as it came out. So note which is closest to the side clip and put it into the new connector next to the side clip. The best way to do this is just do one wire at a time which makes sure you aren't going to forget which goes where.
