Hello, I have a 79 300d which came from Texas with no block heater. Now it resides up here in Toronto. With winter coming, I was planning on installing an inline block heater. I need to know what is the inner diameter of the hose so I get the proper size. |

Block Heater
Don't waste your money on a radiator hose heater. They will only heat the water in the radiator.Get the block heater for around $40 and have it installed.You'll be glad you did.

I did check with Mercedes Benz Canada, and they wanted $90 cdn for the block heater, and 4.5 hrs labour @$90/hr to install. Plus! - they advised me that they would not be responsible for any leaks that were derived from the installation. Add taxes and the bill is easily $700.00. Ugh!!! |

I have seen heaters that are large magnets with a power cord. They are meant to be removed from the engine when you are driving. I have no idea if they work or not.

My '79 300D starts OK down to -20C (-2F) without a block heater. I use 5W30 and have parallel glow plugs. The 4.5 hrs shoptime seems about right.

Block heater
Four and a half hours to install a block heater on a 300D is too much time. Give me a helper and I believe we can remove the engine and transmission in that time.

Wm. Lewallen, I'll have to agree that 4.5 hrs is too much if you are familiar with the car. I don't know what I was thinking, but what I meant was the time it would take me to figure it out for the first time. Once you get the starter removal figured out, I don't know how difficult the frost plug removal is. Can't be that bad. I would definitely try this job myself if the block heater quit working or the car didn't already have one.
On a similar note, a shop once quoted me 2.5 hours to replace the front end upper control arm bushings. It looked like a tough job, never having worked on a front end before. After completing the job myself, I think I could easily do the job in 1.5 hours or less. |

Removing the plug is a chore.
I put one in my old 300D, and used a 36" breaker bar. I almost gave up, but it finally began to turn. If your car has a lot of mileage, the plug may need some heavy torque to get it out. I do agree, a block heater is a nice thing to have. I personally do not use mine unless the temps go below zero F. I have always been able to start mine by simply glowing an extra time or two, and then starting her right up. Good luck with your installation |

Anyone know the ID for the hoses leading to the ACC servo?
