General JTD Fuel Filter

Hi, did my Marea JTD 130 other week, car had done 76k, think by the looks of it, it had been changed before. also did a TD 125 about 5 yrs ago seem to think it was mounted in a similar place, rear of engine slightly to the top right as you look down at engine. Think there was better access on TD125 as I had to remove pipes and the body the fuel filter was mounted on to remove JTD 130 filter, as access was tight. Think it was abot a 35-45 min job,

Special Constable?

I never said I'd win a beauty contest, and no I couldn't get a contract with any hair product manufacturers... :(

I was expecting Sarah to zoom in a bit more onto the filters, rather than include me who was staring up into the sun after being head first in the engine bay for 10 minutes. :rolleyes:

Anyway.. Sarah says I'm special so there :p
 
You do realise you went the whole wrong way about it. Your supposed to undo the nut on the top of the filter and remove the pipe, careful not to loose the two washers. Then diconnect any other pipes and electrical connectors. Undo the two nuts holding the unit to the engine and withdraw it from the car. Remove, refit new filter and replace back onto the car. Same applies whether it by a Bravo or Brava.

P.s I love the way your kneeling on the engine, struggling to remove the filter. You make it look such hard work. It would of been easier to tackling it from the side of the car rather than directly infront.

P.p.s I noticed in your guide you never mentioned a electrical plug connected directly underneath the fuel filter, when you buy a new filter it has a white plastic drain cap on it, you need to remove this and refit the electric device to the bottom of it and then reconnect the wire to it. I was puzzled because if it was connected and you started unscrewing the filter it would of twisted the wire, possibly broken it. Not sure if the JTD130 has it but i can't see why Fiat wouldn't of fitted one to it, i think it electronicly meters the water in the fuel filter, hence the fuel filter warning light on the dash.

On the JTD130 the fuel heater body is held on by 3 bolts. One of which is impoossible to reach without taking apart a whole load of other parts. See the big black thing next to it. I couldn't get a 1/4 inch socket onto that bolt, and didn't fancy taking all that apart. As I could not get the housing free I saw no point in removing pipes which would require new copper washers to get a decent seal.

Do you not think I tried removing it from both sides and stood infront? Given I couldn't remove the housing I chose to get to a point where I could see and reach the parts involved.

Lastly, I didn't have a condensate warning on the bottom of my filter. Couldn't see the wiring for one while I had the filter out so guessed it was not fitted to this model. I had just changed the filter on a Alfa 2.4 JTD (which has quick connect pipes) and also had no condensate warning plug.
 
Ah didn't think there was 3 bolts, well good enough guide anyway. Theres no need to replace the copper washers unless its been done numerous times. The difficult to reach bolts near the black box could of been reached with a ring spanner etc.

The Alfa 156 2.4 JTD does have the connector at the bottom of the fuel filter as my brother has a 2003 Alfa 156 2.4 JTD and i had to disconnect it when i was doing the service on it.

Just check my fiat data cd and the Marea 2.4 JTD does have a connector at the bottom of the fuel filter. Depends on the the filter used. Im guessing yours JTD is a early Marea that came without. Incase your wondering the filter that goes with the sensor is 46793815 and the sensor is 46790125. Thats for the Mk2 Marea 2.4 JTD 130.

Checked the Alfa 156 and the very first earlier 2.4 JTDs came with sensors aswell but again there are two one with and without the sensor. Im assuming the Alfa JTD you worked on was the old 10V 130 aswell same engine as in the Marea so again would be why it never came with the sensor.

Nope. It's a 52 reg facelift 20v.

Even my G reg 1.9 TD SX Tipo had the water sensor in the bottom of the fuel filter - but both these 2.4JTDs didn't!

They must have ran out of the sensors while building them :rolleyes:

Not calling you a liar but the 2.4 20V facelifted version (also known as 175BHP multijet) only came out in production in 2003 onwards.

"There are 2 versions of the 2.4JTD, the 10-valve as used in the Fiat Marea 130JTD and the earlier Alfa Romeo 156 diesels where it was in 130bhp, 140bhp and later 150bhp versions and a 20-valve version as used in the later (2003>) Alfa Romeo 156's as well as some Lancia vehicles."

According to Alfa, all 156's that where facelifted in 2002 all came with the sensors for the JTD.

I think your cars should have this device fitted, but if it doesn't have one then fair enough.
