in summers my local AC mechanic took off the pipes of hot water , which are in the firewall that goes in the heater hose, for better colling of AC.
now in winters i my self attached all the pipes according to the factory settings, the problem is that my heater is not giving hot air inside the cabin. car is fitted with auto fans and thermostat. i drove the car almost 50 kms and checked the pipes which were going inside the heater hose, there was no pressure of gas inside only in those two pipes , the pressure which generally develops in all radiators pipes when car is hot. all others pipes were having good pressure except those two the inlet and outlet of heater hose
is there any possibility that heater hose might be air locked ??
ur kind help is required, as i say u the original car guru .
my car is diesel and it starts easily when cold, but takes very long self if started when warm with out preheat glow plugs
