I am having some issues with the HA, I cannot stop it getting hot. Tonight I managed less than 5 miles before it was in the red again. This is after I took the probe out and checked it was the correct model (check) and re bled the water system to ensure no air locks (check).
Spoke to a friend and he reminded me that RAY has a radiator and its worth swapping them over and see if that helps. So I did swap them over and had just enough time before it got to late and checked for leaks.
Here is a picture of the two radiators (dirty I know) the one on the right is out of Marvin, the one on the left is the out of Ray. lets hope tomorrows drive shows an improvement in the temperature management
I had forgotten the difference in the weight, the HA one is at least three times the weight of the HB one. If it sorts the issue I will need a nice HB radiator PDQ.
