Update on the saga of the cold TF heater.

As suggested I returned to the garage to confirm that the 4 way connector was the part replaced.
They agreed to investigate further.
The mechanic test drove the car and found that the luke warm heater went cold after a short drive time. After discussions and reference to the online diagrams and information we agreed that when the PRT opens then the hydraulics of the cooling system robs the heater circuit of flow.
The 4 way connector was removed which revealed that there was no restrictor fitted.
The garage referred to the part supplier a respected MG specialist and parts supplier who said that they used the connector with no restrictor with no problem.
It was decided in view of the online advice a restrictor was devised and fitted.
The cooling system was refilled.
I carried out a test drive, 20 miles local roads, traffic and a motorway section.
Everything seemed now to be normal. Coolant and oil temperatures as expected. Heater working and hot.
The fans did not kick in some traffic.
Thanks to all who have contributed with advice including those on past forum streams.
Thanks to the garage. Respect to them for undertaking the investigation and work at no additional cost.
It just leaves me with one outstanding question?
The MG specialists seemed to say the restrictor is not needed but without it our car did not operate as it should. The advice from other users is contrary to this.
Clearly there are images of the restrictor from past parts.
So who is correct.?
Thanks
