I fitted into the pipe coming up from the water pump area that goes directly into the firewall. When I did this I found the cabin heater not getting hot either. The Glind heat exchanger has directional arrows on it so I plumbed it that way. I then disconnected the pipes to check the flow and nothing comes out. I released the fill bottle cap and you get some flow from the water pump pipe. I have return the system to normal and found cabin heater still not working. I had to rev engine to 3500 rpm and then it was ok after that. Does anyone know what’s happening here please?Btw, do you also use durags when you ride to protect your hair, especially for the long-haired riders out there? Saw some beautiful durags from
open this.
Hey there! It sounds like you're dealing with a bit of a puzzle with your heat exchanger installation. I'm not an expert, but a few things come to mind.
Firstly, did you double-check the directional arrows on the Glind heat exchanger to ensure it's plumbed the right way? Sometimes, even a small misalignment can affect the entire system.
Regarding the lack of flow and the cabin heater issue, it might be worth checking if there are any airlocks in the system. Sometimes, a trapped air bubble can cause flow issues. Bleeding the system or ensuring all the air is out might help.
Additionally, the need to rev the engine to 3500 rpm before things normalize is interesting. It could suggest a potential issue with the water pump or circulation at lower RPMs. Have you checked the water pump for any signs of malfunction or blockage?
These are just a few thoughts to consider. I hope you get it sorted out soon! If not, a visit to a mechanic or the manufacturer's support might be a good next step. Good luck!
