Congrats on finding the solution Neil. It just goes to show how important even the narrow bore feed to heater matrix is when its constant flow is a design factor in the engines overall heat dissipation, not to mention it carrying the hottest coolant in the whole of the engine.

FIXED!!!!! I tried the suggestions about blanking plates for the rad to no avail. Decided to go back to basics and get the cooling system flushed through. Engine block and heater matrix flushed through separately. There’s a short hose that runs from the rear housing on the head to the heater matrix. This little hose has a spring in it in order to stop it from collapsing I guess. The spring had caused a blockage in that small hose which was easily flushed out. The car is now running at normal temperatures under load and on tick over in a queue. The fan cuts in and now the temp immediately drops unlike before. Many thanks for all of the suggestions, and the time taken by my Morgan friends to write them. Just goes to show that going back to basics sometime is the best way. Would it be possible for you to take a photo of where the hose runs? I would also try cleaning it myself. Thank you very much.

Great news and a big thanks for reporting back. That’s what makes the forum so useful. It is frustrating sometimes when members put their efforts into finding a solution only to find that the end result is never published!

Good to see that you have found the solution, and thankfully it was a simple and inexpensive fix.
I've had too many aluminium engined cars over the years that often suffered from sludge buildup,either due to poor maintenance or lack of use, that a simple precautionary flush through of the cooling system on acquisition , can help avoid sources of potential overheating problems.
This forum is an excellent resource, maybe it could benefit from a known cures section, which would concentrate the accumulated knowledge into a reference section, so the potential solutions are not lost in the mists of time and among all the background noise.

I’ve tried taking pics with my iPhone but keep getting told that my images are over the download allowance, any advice in this respect would be most welcome.

Thank you very much for your efforts. Have you tried using this page? https://tm-img.com/When you upload an image of the right size (I do not know in the moment the max size), you will see a long list of insertion options. The last section at the bottom says ‘BBCode’. Select the first line „Full“ and simply copy it by clicking on it at the right end. You can insert the line into your post as I have done here to show the screenshots. I think there are also good instructions for this on the page. ![[Linked Image]](https://tm-img.com/images/2025/09/11/IMG_6204.png) At the very bottom of this second image, you will see ‘BBCode full’. ![[Linked Image]](https://tm-img.com/images/2025/09/11/IMG_6205.png)

Cannot find an image for 4/4 but its the hose connecting to the lower of the two heater box connections.
