CSF’s new all-aluminum H3 radiator finally addresses all the weak points of the original plastic tank radiator. The most significant failure point on this model is the upper mounting pin, which is made of plastic. There is too much stress on this pin, and it causes the plastic tank to crack. CSF’s CNC machined billet top mounting pin takes care of this issue and will last the lifetime of the car.

The second weakness of the OEM radiator, is the push-connect plate-type oil-cooler that is used to cool the automatic transmission fluid. CSF has beefed up this cooler using a stronger 4-plate cooler which will meet the demands of heavy towing and off-road driving.

CSF’s new H3 all-aluminum radiator is a true “drop-in fit’ including the original threaded plastic filler neck design now machined in aluminum. CSF includes an embossed cap cover for the original plastic cap to complete the high-end look of the 1-hour hand polished mirror finished radiator.

This radiator will fit with the original AC condenser, fan shroud, and all original mounting brackets with no modifications needed.

Stronger core design with reinforced aluminum tabs in all four corners

All-aluminum CNC machined side mounting brackets. A vast improvement over the OE plastic tanks.

    Does this radiator have more cooling capacity or are all the improvements in strength and appearance? What I want is a replacement radiator that does a better job cooling. I don’t care if it’s polished and pretty.
