Radiator P1 C30 C70 S40 V50

Some P1 models (mostly PZEV models) were equipped with radiators that had PremAir catalytic coating but we are only selling uncoated radiators.  

Volvo is obligated to replace coated radiators with the same type during the car's warranty period.  Once the car's warranty has expired, the coated radiator is not legally required. The main reason for this is the simple fact that the car's OBDC system cannot monitor whether the catalytic coating is functioning or not.

The coated radiator and the un-coated radiators from Volvo are identical except for the coating applied to one.

Here is some information on PremAir coating:

“Traditional approaches to pollution control have been to develop benign non-polluting processes or to abate emissions at the tailpipe or stack before emitting to the atmosphere. A new technology called PremAir Catalyst Systems takes a different approach and directly reduces ambient ground level ozone. This technology can be applied to both mobile and stationary applications. For automotive applications, the new system involves placing a catalytic coating on the car's radiator or air conditioner condenser. As air passes over the radiator or condenser, the catalyst converts the ozone into oxygen.”
