The altenator went out replacing it I stripped the hole on the radiator to the transmission after replacing the radiator the car over heats. We took out the thermostat and ran the car without it; it still over heats. What should I do? I noticed the coolant coming out of the resivour once it heated up.

Do you
have the same problem?

After replacing the radiator the car over heated. The thermostat was then removed. We ran the car without it and it still over heats. What should I look at next?

A chemical head check is a quick and simple test for a head problem, with coolant being expelled I am thinking that there is a build up of pressure in the system due to a combustion leak, a faulty water pump will not normally give you your symptoms, check the head gasket first. A faulty water pump expecially with no thermostat will not cause overheating as the natural thermal flow of water with no thermostat will over come any pump preformance problems.

No not at all, if head gasket is faulty, head gasket set and proberbly minimal head machining to rectify any warp, bend or cracks, all standard procedures.

As I am in Australia, my pricing will not help, you should be able to get a few quotes, this should give you a fair idea.
