Spent some time with the car today fitting the new coolant pipe and noticed a couple of interesting items when doing it.

The pipes and the fitting in the engine bay did not look quite right and then noticed that as the car has LPG its taken a feed from the cooling system into the LPG pump in the engine bay. Now due to that installation a couple of problems have been caused, the metal T pieces for the tapped feed are 14mm which is fine for the pipes going to the LPG but the D2 coolant pipe has an 18/19 mm internal diameter, so not a good fit.

Hence I have ordered new pipes, clips and T pieces to get the job done to a much higher and hopefully reliable standard.

Finally and what I believe was the root cause of the failed coolant pipe is due to the above LPG installation. The heater hose is the one that failed and that normally connects to the right feed from the heater matrix in the engine bay. As this has LPG an extra pipe and T piece was fitted for the coolant feed, nothing odd in that but due to the way it was installed it pushed the heater hose 2 to 3 inches down into the engine bay and much closer to the exhaust.

Therefore we had a hose closer much closer to the exhaust than it should have been and I suspect failed much earlier than normal due to the increase in heat is was exposed to.
