Hi ,
I have yet to install a system in any cars , but have been reading up on it . I believe if you go to the mercedes section of this site there are answers to all of your questions and several pics in the past posts . One recent post I read showed where someone had run the lines under the carpet on the drivers side , he had pics posted . Good Luck |

T back back into the circuit by the water pump. There is a 5/8" hose that runs from the pump to the firewall (it might turn into a metal tube at some point). Add your T near the pump and run the hose along the top of the radiator.
As for the rest, I just pour the stuff in and go... 1984 MB 300D, 425K, original engine and trans. V80 Blend (80% vegetable/20% petroleum) since 400K. 1982 MB 300SD, 220k. |

Ooops, sorry, I misread your post. You want to get the coolant from the hose that comes out of the block by the oil filter. By careful how you mount the T - iy may get in the way of changing the filter if you're not careful. Then the coolant will be returned to the hose by the water pump. I'm assuming a mid 80's 123 or 126 Mercedes. 1984 MB 300D, 425K, original engine and trans. V80 Blend (80% vegetable/20% petroleum) since 400K. 1982 MB 300SD, 220k. |

Now , that's a good answer which I'am going to use right away. However my search on the Mercedes thread of this forum does not give me much info on the different ( if several) ways to practically route the hoses from the trunk to the engine bay.
Any ideas ? koolfrog |

this hose routing issue was the challenge of my conversion too. I had planned to run it inside the cab, but shouldn't get a hole drilled in the firewall between the engine compartment and passenger footspace. Nor could i figure out how to get it into the trunk; if i'd drilled below the back seat it would be outide the vehicle again. So I ended up just running it under the car. Not happy with it. You just need to get under there and find the best route. get it on ramps.
Pwdrluvr has his in a rigid pvc pipe and I have the pipe and am thinking of doing it too. let's ask him if he's had any clearance issues or if he's taken it off pavement at all or over speedbumps???? and i always like to show this picture  this is what is meant by hard to get at the oil filter. i needed to cut that hose a little closer to the engine, but there you have it, that's where you tee in... more about my conversion here |

Is there any reason why the tank heater lines should not be connected "in series" with the car heater hose , ( I mean the coolant would fully flow through the tank heater and then to the car heater)?

Here are the connections I have used to tee into the coolant system on my '84 and my wife's '82 300Ds.
 At water pump  At head. note clearance to change oil filter - Colant line is cut, but no hose removed. The cut is in the vertical part of the hose and the brass tee is fitted with hose clamps.

How does one remove and replace the coolant, being sure that the coolant fills the entire system? I know there's a plastic drain plug on the bottom of the radiator, but how do you make sure it's all out, then how do you get it all back in? The pictures are sooooo helpful, btw. Thanks! -=Aaron=- '84 300D |

I have done two mercedes one 1993 300SD the other a 1984 300SD.
I did the 93 first and I wanted it to be perfect. I ran the HIH inside the rocker panels and over the tires inside the fender liner. I used copper tie downs for plumbing to hold the hose over the tire and under the fender liner. There was 6 inches between the engine bay and the frount of the rocker panel that were exposed to the elements I bent a piece of sheet SS to go over the hose. It was real sharp all my pictures are on my old computer or I would show you. At the rear of the car I removed the rubber drain plugs and ran the hose in that way. The hoses ran across the back inside of the trunk and up the other rocker panel to the engine bay and the T was back at the water pump. On the 1984 I zip tied the HIH to the brake lines from the engine bay to the trunk and again went in thought the drain plugs but kept both hoses on the same side of the car. The 84 was much easier.

Maddasher, I am in the process of buying a 93 300D. I have been running an 82 240D on my own system for 3 years now. No problems. My big delima is where to run the coolant lines to the tank in the trunk. Under the car or in the cabin. Could you let me know in more detail how you did it? Are there any other issues specific to a 93 300D I should think about? Thanks, Mark 82 240D 93 300D |

On my 90 sdl I have the HIH go straight down below the oil filter. I drilled a hole in the catch pan and zip tied back. The hardest part was going past the rear diff and 1/2 shafts...I zip tied close to the rear diff. I drilled a hole into the spare tire compartment near the rear top. A big gromet didn't prove to be water proof so I put 1/2 a tube of goop and it's held fine thru the winter.

Here's how I routed the lines on dad's 300sd.
I took a lot of pictures around the rear coil... that's the tricky area. http://biodiesel.infopop.cc/eve/ubb.x?a=tpc&s=447609751...59605551&m=215109725 FWIW, ignore the diagram for the heat exchanger. It never worked very well. Just recently changed to a Kaori 16 Plate FPHE and get much better heat now. jake ---------------------------- '99 Benz e300d (SVO conversion underway) '87 Samurai LWB - parts hauler & mule (ACME VW diesel kit, HoH, Pollak) ***Garage full of VW 1.6 + 1.9 bits... for sale!*** |

Here's how I did a customer's '85 300 TD:
2nd picture. 300TD conversion As another poster mentioned, the T gets in the way of changing the oil filter . I just push it up out of the way and hook it over the throttle rod with the clamp. |
