Hi again !! I am a bit puzzled or, more correctly, a bit concerned about a loss of coolant from the P38. I have a feeling that I know what it is but I am hoping that someone, who has experienced it, might be able to sort of confirm my suspicion.
Now that the weather has got a bit cooler I have had the heaters on warm or hot, to give a bit of extra warmth in the vehicle. I have noticed that the coolant is now disappearing at about a quarter of a pint over a 50 mile shopping/going for coffee journey. This is in comparison to a journey to Scotland, two months ago, which was about 600 miles in total and didn't use any coolant.
So, basically, there didn't seem to be coolant loss when the heaters are not used, but now that they are used the coolant is disappearing.
The issue seems to only be on short, multiple journeys, and seemingly when the heaters are used. I strongly suspect that the carpet is a bit damp under the heater unit, inside the vehicle, and I am wondering if this could be caused by the famous rubber seals on the heater pipes from the engine into the cabin leaking ?
