Thread: Series 3 heater connection problems

If by “switch “ you mean the tap then I don’t think it would matter. It just stops the flow. But I guess there will be argument.

Could you please give some info about the kit you used for the 300? Have you kept the turbo?Are you using the Series gearbox? I have a S111 that would love to have a 300 in it.

thanks Jay - yes I meant tap.

Happy to provide any info on the conversion. Not sure it was the wisest choice to do the conversion on my first Series but I have loved the journey. I bought a Steve Parkers 300TDi conversion kit from the UK. The kit keeps the turbo and joins the standard series gearbox (with a little bit of angle grinding help . That said I have also put on a Fairy overdrive as a precaution.

Here are some photos. But please feel free to message me and I can talk you through the process and all the lessons I have learnt. I am based in the Northern Suburbs of Sydney if you are also in the area.

Thanks, Chris

Looks great. Steve’s site is down, but I’m in no hurry. But I have a S111 and a very untidy D1 as a donor car. I would need to talk to an engineer I guess.

Hi Chris,
It's my understanding that a 300 tdi heater it part of the cooling circuit, and must not be blocked off, either with a tap or by blocking the heater hoses.

If you need to disconnect heater you must run a hose from the steel pipe above the inlet manifold to the water connection on the back of the head.

Good point. You can get a bypass tap that switches from one circuit to the other. Have to be careful with bleeding I guess.

Thank you for the further information - makes it a little more complicated or fun - depending on which way I look at it.
