Re: [diesel_mercedes] Basic Injector Service

 

Max,

They're different. What I found searching is:

 240d 115 bar

 300D Turbo 135 bar

Yes, you can replace the nozzles, first lap the surfaces and clean, and then pop test.

Pretty much yes .

I was reading the Factory Service Manual and it says they want me to lap the sealing surface of the injector body halves , this of course would tend to raise the pop pressure point....

You're also supposed to clean the disassembled injector parts in a sonic cleaner , I happen to have a small one a grateful Customer gave me ,  then you're supposed to clean the nozzles with brass brush bristles (brass only !)

 I'm not sure I want to get that involved with it all , so far I've just cleaned and tested bunches until I get a set as necessary for that time , then I give the other injectors away to others who'll overhaul/service/rebuild them .

Re: [diesel_mercedes] Coolant running out of 116

 

Not a good description but it sounds like it could just be the hose to the overflo tank.? If it is it could mean the radiator needs flushing or replaced?  How about a picture? Max

From what you're describing, it sounds like coolant is coming out of where the a/c condensation drains out.  That would indicate a possible leaking heater core, or, more likely, a short hose that connects the heater core(s) in the passenger compartment to the cooling system under the hood.

You can get a better idea of what goes on in there from the factory service manual at the W116.org site:

We have a problem with my wife's 1980 300sd leaking coolant. Yesterday, she called and said that the car was was overheating. After numerous stops to refill with water, we finally got her home. Found that the water was coming out of what appears to be an overflow tube on the passenger side of the firewall. This tube is 1-2 inches wide and outlet is made to remain closed but will allow fluid to come out if needed. Don't know how water could get from a closed system into this "overflow" tube. My Haynes book does not show anything and I could not find any pictures/diagrams on the internet. Any suggestion or advice on how this works or how to fix this problem would be appreciated. Thanks Tom.

Re: [diesel_mercedes] Basic Injector Service

 

I wonder if 300 or 300 turbo injectors are the same as 240's. I have 10 of those I could mess around with. I have a pop tester too. Haven't used  it for 20 years. Max
