General Replacing spark plugs T-jet Help

[carlorff]

Hi

On Saturday I was trying to replace spark plugs on my Fiat Bravo t-jet. I did get to the part where I can see the coils. But I did not know how to disconnect the connectors with the yellow "switch". I use to do similar stuff on my ex-gf Yaris with no problem. But Bravo has some sort of connector I do not know how to disconnect, and I do not want to damage the car. Can someone please tell me or show me with pictures or video? I checked in e-learn and could not find the description on how to disconnect the connectors.


PS: Please take a look at the picture.The picture is from another car from this forum.

Pull the yellow bit out and then release the plug like normal

:yeahthat: you either need finger nails or a small flat head screw driver, just be gentle with them

I managed to lift the black plastic on the top of the yellow bit...with a small screwdriver...than I pulled the yellow part out. I tried to pull off the plug with that released, but it wouldn't budge at all.

IIRC the plugs all need to release and withdraw as a set, and there is a fastener holding it to the cam cover

its tricky but take care and its possible

Not entirely, you can take them out one at a time but probably best to remove the whole thing to stop snapping the plugs.
Mine are snapped

I think all 4 connectors need to be disconnected then the full rail unbolted. Im sure theres only a few 10mm head studs holding it all in place. Coils are held in with 10mm head stud also.

i think you just proved my point!

I took it to local Fiat garage and they replaced them.They charged me 18€. Thank you for all your suggestions.. if I had more time and did not need the car next day I would take more time and replace them.Bur I was held back by an unknown plug and almost no spare time.

The yellow tab is a locking device. You pull that out gently, and then you can push the clip down to release the plug. It is definitely easier to release all four at once, but you do need to unbolt the rail, and a breather pipe bracket nearby. That involves the use of a 13mm socket, and a 5mm allen key (if I remember correctly).

When it comes to servicing the T-jet, the spark plugs are an absolute piece of cake compared to replacing the engine oil filter!

Amen to that! Oil filter is a right pig to get to!

Its difficult in the Bravo, which has a large engine bay! What about the likes of the Abarth 500 with the same engine in a smaller bay...

Removing the first boost hose helps enormously, but still a bit fiddly to get it out. Certainly far more fiddly than it should be to change an oil filter!

Where is the oil filter on the T-jet then out of interest?

Is it not front of the block on the drivers side

Yes it is, but access to the heat shield bolts is almost impossible without removing the hose to the intercooler. Then you still have to take out the filter which spills out a lot of oil (even if it was drained previously).

Basically it's a much harder job to do that it should be. I had access to a ramp, all the tools and it still sucked.
( hard to maintain => take it to the dealer to get serviced..or get a newer car)

Yeah i do mine over a pit and it is awkward. 27mm nut on it too, and its difficult to get a 27mm spanner that is short enough ;-)

 

[Most Easterly Pandas]

27mm nut? Is it not a spin on can filter.

 

[aurick86]

Oh no.. gone are the days of simply replacing the can filter.. now you have a replaceable paper filter inside capped with a plastic cap/ body .. that uses a 27 mm spanner.

I guess it pollutes less, but man is it a PITA to replace.

And its a fairly generic filter. The purflex oil filter housing in the T-jet 150 is the same as several other manufacturers. My oil filter can fit Vauxhalls and other makes...

To make things confusing, my local parts shop show a different filter for the 150 to other 1.4 models. Since they are all based around the same block, you'd think the filters would be the same...

I suspect the 1.4 NA is the same can filter as all the other 1.4 lumps fitted in the Panda 100hp and Stilo etc. That why I was surprised the Turbo ones seem to have different oil filters, as I thought it was an identical engine just with a Turbo bolted on. Looks like there might be a few more changes to the lumps auxiliaries though?
