XC70 D5 185 injectors fitting
 

Hi.

Sadly the source of the missfire on injectors 1 to 4 is definitely Injectors after new terminal connectors and Cloned ECU didn't help.

Found some second hand injectors quite reasonably priced , question ,Can I reuse the old injector clamps and bolts? Will get new copper washers.

I know injectors need coding , would it run ok without coding? I would imagine my local volvo specialist would want 100 quid to code all 4

Thanks

Can't comment on the clamps & bolts, but the engine should run. Maybe not very well, but should be enough to nurse it to a garage.

When I did the injectors on my girlfriends D5 V70 58 plate so I think it's the 160 bhp. I replaced 3 out of 5 with the exact part numbers from a breakers and they work perfectly with no coding. New copper washes/seals are essential I managed to salvage the best of the clamps and bolts I had form the original and replacements, but if any look slightly flattened I would replace them. Also lock tight the threads on the bolts.

The clamps can only be used once , they bend and you will not get the same clamping force the second time resulting in leaking seats and oily carbon deposits which bake the injectors solid into the head .
volvo do fitting kits , you will need one for each injector , you are also supposed to replace the high pressure pipes when you remove them .

Thanks.

My Injectors part 30750283 have 7 digit code , some replacement same part numbers have 8 digit code.

Does it have to be 7 digit code inorder to code replacement ones in?

What are the chances of it running without coding

Also whats the torque setting for the injector clamp bolts on D5 185BHP?

13 nm ..... not very tight at all
