Could be air in the system or could be debris in the radiator area. These cars are bottom breathers and suck up a lot of stuff in that area. You might want to check and see how that area looks. Remember that it may not be just in front of the radiator that could be the blocking air flow - it could also be gunk in the fins of the radiator itself.
