We are sorry you feel dissatified with your experience. We did a coolant pressure test which is what allowed us to discover the cap was leaking. The cap only leaked when pressure was placed on the system. So a full diagnostic was performed on your vehicle. We shared the diagnostic fee upfront. We on occasions have unfair evaluation on sevices when compairing on a apple to oranges level. Clients at times can get better pricing on purchasing parts themselves or performing work themselves. We are glad we were able to help with your car. We are dissappoint that you do not see the value of the services we provide.
