Seized fuel filter body

clonagam

I drive a 2008 Volvo V70 D5 SE G (MY08) 5DR Auto 2400cc diesel 136KW (185hp).

I have been unable to unscrew the plastic housing that contains the replacement paper fuel filter. Clearly, Volvo must have a special tool which probably fits projections on the filter body to give the extra grip required.

I have tried metal strap and chain filter removal tools - and some others without success - the filter body is locked solid. There is a moulded nut at the base of the filter but it is not accessable to use of a socket. Using an adjustable spanner on this nut seems to put a dangerous twisting action on the plastic body of the filter body and I felt there was a risk of major breakage - so I desisted.

My question is: Can anyone suggest any safe method to unscrew the seized filter body that I haven't already tried?

P.S. I have a picture but can't upload it - thread rules!

Remove the whole assembly and put it in a vice, get a couple of Boa constrictor wrenches and use them in opposite directions.

This is my second reply - the first seems to have vanished into the ether!

Many thanks for your much appreciated suggestion.

However, as a modest DIYer, I don't think I am brave enough to tackle the dismount of the whole unit. Frankly, I don't know what that might involve. The working space is severely restricted (who designs these locations for parts that have to be accessed regularly?). I am also working on my driveway dependent on weather. Luckily, I had been trying to replace the filter in advance of its due date so I have a little more time to consider the issue before I bring it to the Volvo people.

I used a metal strap type oil filter wrench. It was tough but it worked well. Mine is also a D5.

Great to hear from a fellow owner of a D5 and to know that you were successful with a metal strap type wrench. Mine disintegrated with the hammering!

That's what I used:


Someone must have tightened yours a bit too much?!

As a D5 owner you may be interested in my average fuel consumption over a four and a half years' operation (mixed driving). It has averaged at 9.306 litres per 100 kms (or 30.35 m.p.g.).

Another current issue is deterioration (leaks) of the plastic tubing serving the windscreen washer. The unit is in another difficult to access place - buried within the nearside front wing. Local Volvo agent couldn't supply tubing (referred me to an aquarium) but I sourced some in the U.K. Having initially tried without success to access the fault through removing the wheel arch lining, I finally gained access to the problem area by removing the plastic fairing under the front bumper. The tubing was perished in several areas - very poor material! Incidentally the U.K sourced tubing is rubber - not plastic.

Ours is averaging 30 MPG as well but it's an XC90 so a bit bigger. Only problems so far have been a leaky crankshaft seal and leaking engine mounts that are vacuum operated.

Yes, that seems to be the case. I believe that the recommended torque setting is 25nm.

Thanks for the picture of the filter wrench. That's the kind I used. I used a hammer on the screwhead attaching the steel band to the travelling nut. The steel band separated at this point.

Here is a picture of the seized fuel filter unit that has resisted all my attempts to free it with standard filter wrenches. Any ideas about how I can engage some tool with the projections to see if I can move it?

This is probably your only bet: https://www.amazon.co.uk/Laser-6238-Diesel-Filter-Wrench/dp/B0111G17WQ/ref=sr_1_1?ie=UTF8&qid=1473195911&sr=8-1&keywords=volvo+fuel+filter+wrench

It's the exact tool they would use in a Volvo dealer!

Many thanks for that steer. It looks like what I need. But my engine number is not listed there so I must check that out carefully before buying.

Thanks Shietpilot - you have helped me greatly. I bought the wrench and it did the job. I had to use a torsion bar to budge the filter housing!

Glad it worked out for you! I got away without one on mine :P

If you ever need mine I'll be glad to loan it to you
