I have a punto SX 1998 model. Recently my heater has stopped getting hot
where it used to be really fantastic - 5 mins in the car and you'd be
Resently I have had a prob with my electric cooling fan which has resulted
in the car overheating and boiling over on a couple of occasions. It was
after the last time that the heater in the car packed up.
Anyone got any ideas?
Several possible causes after a boil up
The boil up stirred up a lot of sludge that is blocking the
fine tubes in the heater matrix.
Air in the system.
Thermostat has disintegrated, or is stuck open.
(that was my problem)
Kinked hose or heater valve stuck shut.
(have had that, early valves used a rubber bung, later
ones a gate valve.)
If the engine temp gauge is showing normal temp, the I'd open
the heater tap, disconnect the two heater hoses, and see if
you can flush water through the heater matrix with a garden
hose. If that flows freely you know that the hot water can
circulate. The pipes seem to be twin walled with reinforcing
braid in between. The inner wall disintegrates, and the outside
still look ok. As your car has over heated the hose may be the
problem, hence the flush through test. Won't do any harm
