i have an issue with my preston staying within my resevour,i had a airlock and got it removed at a local garage, when all seems well, im loosing coolant ,dripping by the passenger side by the oil filter area.also had a radiator flush and refill performed , im getting lots of heat and cool air , but seems that when i opened the pressure cap for coolant its still bubbling ,the air lock does not not want to come out , could this be possible be something else although the mechanics say that there is no visual leakage . i also hear a thump thump sound when i turn off my engition , sounds like somethings drainning
