Move ignition coils on 2.7 Hilux
This is something I wanted to do ages ago and at long last did it this weekend.
The ignition coils on the 2.7 Hilux is located at the front of the engine right above the fanbelts. So if you drive through a little bit of water the fan belts splash water on the coil which often lead to a misfire. To move it was rather easy. You just remove the whole bracket with coils on.
Cut open the wiring harness to get the wires out and relocate it. You do not have to cut and join any wires, just re-route them. The only mod to the wires was that I swopped no 1 and no4 plug leads.
Finding the best spot took me the longest:
First I wanted to put them on the existing bracket sideways on the firewall. It looked as if it would work and I had to cut open the bracket in order to run the brake booster pipe through the bracket. I attached it to the firewall only to find that the bonnet is pushing against it when you close the bonet, it was too high. I then considered putting it behind the airbox, but that would have been too far from the plugs and you would need longer plug leads. I then simply drilled holes in the ridge on the firewall just below the brake booster pipe.
Attached the coils to it with M6x25mm stainless bolts with nylock nuts. All I have to do now is to neatly close the wiring harness again.
O ja, and of course I had to bend the brake booster pipe a bit to get it away from the nuts and to attach it again using the original brackets
If you skip the "figure out where it must come" process and directly fit it to the firewall, this mod should take between 30 minutes and 1 hours. You will need a sharp knife to cut open the harness, a 10 and 12mm socket, 6mm drill, drilling machine, 4x M6x25mm bolts with nylock nuts and some insulation tape to close the wires again afterwards. So the only expense is the 4 bolts with nuts.

Re: Move ignition coils on 2.7 Hilux
Good plan!! .... and out of harm's way! One wonders why the Toy engineers put it there in the first place .... cost cutting, maybe .....
When your road comes to an end ...... you need a HILUX!.

Re: Move ignition coils on 2.7 Hilux
There must have been some method behind the madness.
What I also wondered is why the one coil is situated higher than the other (see pic below)
By putting it there it is, as already mentioned, where it can get wet, secondly all the wires have to run all the way to the front of the engine just above the exhaust manifold and the coils are subject to the vibrations of the engine.
Unless I overlook something I think the way I have it now should be better.

Re: Move ignition coils on 2.7 Hilux
I heard the nicest description for a 4x4 on Saturday night.
We attended a party and the one guy, who is a bit more attached to his feminine side, walked with us and asked where we parked, I showed him the Hilux and he said
"Oh, it was you who came in with the BUTCH WAGON"
So Donkey, this is a butch wagon not a m0ffie trokkie, the engine can be a bit dusty

Re: Move ignition coils on 2.7 Hilux
I hope somebody can help (Hoppy?)
Today I noticed a fine krrrrrr sound at the dashboard behind rev counter.
I later realised the sound is coming from the engine bay
I am not sure if it is a vibration or if maybe it could be the coils which are making the noise
Do those coils build up and break a magnetic field big enough to make such a noise?
I cannot figure out if the frequency of the noise change when I rev the engine because the moment I rev the engine slightly the engine's noise becomes more than this krrrr sound.
The sound wont bother me much but I would like to know what is causing it. I am afraid that maybe it can be the coils and if it is a magnetic field that it might stuff up something else like other electronics.
Maybe there was a reason why Toyota put the coils right in front of the engine.
Went to Cape Town and back and the bakkie drives very good after I removed that heat tank. Had a strong wind on my way to town and was doing about 100km town driving. Filled up again tonight just outside Langebaan and consumption was 7.5km/l which I dont think is bad for the strong wind and town driving, but cannot say for sure it is because I removed the tank. One thing I can say for sure is that the pipe is now ultra cool. When I stopped at the Engen tonight to fill up, I opened the bonnet and toughed it, it was not much hotter than the ambient temperature. Will test the consumption more over the weekend and will then see.

Re: Move ignition coils on 2.7 Hilux
Pieter the tank you removed is not a heat tank, it is a resonator, it works like an exhaust silencer but yes it does induce additional heat to the intake. The main function is to cancel out intake noise, on the face lift models it is made out of plastic. The heat for cold conditions is supplied by a pipe that feeds hot coolant through the bottom of the throttle body thereby heating it up. You can bypass that as well, but I did not realy find a big difference. You will notice if you remove both resonators and the piece that goes into the fender then the intake will start to sound like a golf with a drilled airbox. Yours goes into the snorkel which may be why it is not as noticeable.
The problem seems to be that if you modify one thing you affect the calibration of the sensors and you preferable need to compensate for that as you now have changed your reference points.
Good luck with finding the cause of the noise.

Re: Move ignition coils on 2.7 Hilux
Nothing else, I guess it is driving style
If you go over 130 you must be willing to pay, I try to stay between 120 and 130

Pieter sit 'n stukkie rubber tussen die coil bracket en die bakwerk, en kyk of die geluid weg gaan. As dit dieselfde bly weet jy dit kom van iewers anders af.

Re: Move ignition coils on 2.7 Hilux
Pieter I will, since those coils can be anywhere I decided to just loosen them and put them on the engine, then start the engine and hear if the noise is gone.

Re: Move ignition coils on 2.7 Hilux
Dis n mooi plan, ek dink dit kan n effense geraas afgee, daai is n mooi plek en die drade pas mooi, miskien moet jy net n aluminium plaatjie buig en agter om sit, plak net bietjie double sided tape tussenin, die aluminium sal ook die hitte weglei
