Sound advice and good service. Only issue is with product itself insofar as the hose connector does not grip the hose from the water pump because the external diameter of the ribs is slightly less than the internal diameter of the hose. This means a jubilee clip is needed but it is not always possible to fit one. On their advice, I used FPTE tape but even then had to use bit of ingenuity to ensure a tight fit. I'm sure I can't be the first person to point this out and it is something the manufacturer ought to be made aware of. That having been said, the service both before and after purchase was excellent.
