Coolant Hoses
 

Hi,

I was hoping for some help.

I have a 1984 300TD that at some point had a Lovecraft Biofuel conversion which I want out. It wasn't in use when I bought the car although fuel lines and coolant still flowed through it but I want to put everything back to stock.

I've re-routed the fuel lines back to the way they should be but the coolant lines are a hash of splices that have been cut in and diverted into the Lovecraft system and out the other end. I've worked out what should go where so I can pull the whole Lovecraft thing out but I need to buy new hoses.

I'm struggling to find the names of the actual hoses I need to order. Is there a diagram anyone is aware of with part numbers (awaiting a Haynes manual to arrive)

Many Thanks

Not familiar w/ Lovecraft, but I expect they just tapped into the heater hoses. If you can't find the factory hoses, it may be possible to find others with the correct bends. My 2002 T&C minivan w/ rear heat has 5/8" hoses with U-bends similar to by 300D's hoses that curve around the oil filter and mono-valve, so look like they could be made to work. But in my T&C, I recently replaced all the factory heater hoses w/ 5/8" silicone (lasts longer) and it made all the bends OK. It is more flexible. If you get the 3 or 4 ply version it is less likely to kink. I may try in my 300D's when the factory heater hoses age. Another possibility is molded silicone hoses, which tuners retrofit in recent cars. Check ebay.

Sign up and get familiar. (It's free with a US credit card) You can call into the dealer or use the p/n's for ordering through places like PeachParts.

Here is a list of 1981-1985 w123 300 series with auto climate control coolant hoses that I've gathered in the past.
