Hi everyone, I have a 2005 LR3 HSE with 169k miles. I have been smelling coolant from the front of the engine for a while now and the level with drop very slightly every couple of hundred miles. I replaced the water pump, thermostat housing, coolant reservoir within the last 20k miles. It is also not a problem with the bleeder. I pressure tested the system and it looses about 2-3 psi over 5 minutes or so. I also use an airlift 55000 to refill the coolant and i can't get it to hold the recommended vacuum now. It will hold about 11 psi vacuum instead of 25. I have used the airlift in the past to successfully refill after doing the water pump with no issues. Does anyone know if the small upper hoses that go to the thermostat and throttle body should contract during vacuum like the large hoses do? They currently don't contract like the rest. I hear gurgling through those upper lines, the throttle body, and the thermostat area while it is losing vacuum. Anyone have any ideas? Thanks!
