Hi,
For over six months I have been experiencing coolant loss, recently heater stopped blowing hot air.
I have taken the car to various shops. They are unable to locate the leak, some say it is a blown head gasket, others strongly disagree. The car fails the compression test and overheats. A week ago I had a brand new radiator replaced, since Tire Engineers claimed they finally found the leak in the radiator. Unfortunately the leak is there, everything is the same. Please advice.

Also, air in the cooling system could cause no heat.
