Best Radiator Repair in Doylestown, PA

In aluminum, 2 rows of 1" or 1.25" tubes should be plenty for most street and mixed-use drag vehicles. Our 2 row models will outperform a copper/brass 4 row by about 10-15%! Also, you don't want a 3 or 4 row alumnum radiator. You want bigger tubes with an aluminum core because of the way it transfers the heat.

Not necessarily. Flow is not as important as pressure. You want pressure in your system to reduce cavitation(steam pockets that get trapped on the walls of the system. One commonly overlooked aspect of increasing pressure is the Water pump pulley to Crank pulley ratio. You always want your crank pulley to be bigger than your water pump pulley. (overdrive your water pump)

Most vehicles are set up with puller Fans from the factory. Pulling fans pull air through the radiator at least 20% more efficient than pushers. One reason is that you can only create a suction affect by pulling air. A pusher fan would perform worse if a shroud was mounted on the pushing side. That would block forced air from hitting the radiator when at cruising speeds. Pusher fans also restrict air flow into the radiator at cruising speeds.

Debate continues as to whether to include louvers in the shroud. The louvers allow for better air flow at highway speeds as well as offering an ornamental look. With no louvers, the shroud creates a vacuum affect and increases air flow, speed and cooling efficiency at slow speeds. Several companies have even tried to settle the debate by adding rubber flappers to the shroud so as to keep the suction affect at idle speeds but allowing the forced air to blow the rubber flaps open at highway speeds. This is a clever idea but we feel these rubber flaps look cheap and are prone to falling off and still don't create a good enough seal. Cold Case maintains that most owners are looking to solve their overheating issues when stuck in traffic. Therefore, we maintain that the shroud should be fully sealed for maximum suction affect as this is dramatically more efficient at traffic idle speeds. The single 16" fan hole (or 2 12" fan holes) provide plenty of highway breathing for most situations

If you've received a radiator with a relief cut it is NOT a defect. They are stress relief cuts that allow optimal thermal expansion while maintaining the highest heat-transfer performance.
