[diesel_mercedes] Fuel Injector Service

 



O.K. Sarracho ;

Yes , you can remove and re install them .

No , you MUST NOT TAKE THEM APART AND TRY TO CLEAN THEM ! this is because they're calibrated very finely and this calibration will be disturbed when you open them up plus a tiny bit of dirt smaller than a human hair will screw them  up .

You'll need a 27MM socket , for the injector proper , if you post a clear photo of the injectors I'll tell you the correct SEARS Craftsman # , or I can give you the E-Bay # for a nice one I bought that's not very expen$ive .

If you have the old Mercedes tool kit go look in it until you find the 17MM wrench , it looks cheesy but decidedly it is NOT ~ wire brush all the rust off it until you can rub a clean white paper towel and get no color on the towel then use that to loosen all 8 of the injector pipe nuts , loosen only then unscrew them all by hand and DO NOT LIFT THE PIPES until all 8 nuts are loose and able to be lifted up and away from their threads .

More later , you'll be wanting at least one can of Aerosol starting fluid to clean things with , some clean light colored heavy paper towels or well washed old thrift store towels .

Once you have all four injectors out , they need to go to a Diesel Shop , one that had the blue and white BOSCH INJECTOR SERVICE sign on it . they're not terribly expen$ive to have serviced/rebuilt .

If you're in So. Cal. I know a good place .

DO NOT skimp nor skip steps in Injector servicing else your car may be ruined beyond repair ! .

No kidding , YOU can do it but gently and ever so carefully .

I have to go now but I'll be chancking back and will assist in any way I can just like the good folks here did for me years ago .

'K ? .

Don't worry , soon your 'Benz will be purring again .

I did change my fuel filter. The fuel lines and tank was professionally cleaned about a year ago. They are probably the original. It's not getting very much power, smoking, rough idle. So I thought I would try to clean them myself!
