Over a week ago I had my air con serviced and naturally the engine was left to idle on a warm day on the drive.
The air con works perfectly and so I parked the car (1.7) back into the garage and left it for a good few days. There was no wet patch or obvious loss of water on the drive however when opening the garage door there was an obvious large patch of coolant under the car which had soaked into the garage carpet.
Under the bonnet was nothing obvious, the expansion tank was empty and the only tell tale sign of a water leak was the residual drips around the sump of the engine and nothing obvious from any coolant pipes. Again only small amounts of pooling around the gearbox fins.
I refilled the expansion tank and tried to copy the scenario and left it run for some time however sadly there is literally no signs of a leak!!
The only theory I have is that when having the air con serviced, this was the 1st time the car has run since November which is when I had the cambelt done & remember I had a nightmare trying to bleed the system.
Is it plausible that there was still air in the system and due to the weather being warm and more strain on the engine with the air con running that this made the expansion tank cap release enough coolant after I parked up not realising there was an issue?
Any thoughts would be appreciated, I am led to believe the Puma & Fiestas of that era are prone to air locks?
I have ordered some new coolant pipes & a new expansion tank anyway just in case.
