  • Features: 1" wide core tubes, No Epoxies,100% TIG Welded, 16 Fins per inch, Temperature Sensor Provision, Air Pressure Tested,Billet Filler Neck, Cross Flow Design, .083" Mounting Flanges Inside the radiator, the engine's heated water/coolant flows into the radiator and flows across the numerous tubes.From there the heat is transferred to the fins of the radiator.The fins are air cooled by the airflow of the fan and vehicle speed, which is the only way to dissipate the heat from the fins - thus cooling the water before reentering the engine.Our aluminum radiator with the 1" wide tubes and 16 fins per inch provides excellent heat dissipation. Our radiator uses a common 3/8" NPT fitting located in the cold side of the tank. This location provides for an accurate temperature reading of the fluid as it enters the engine.Our radiators are air tested a total of 3 times throughout the building process. Air can detect a leak before water.Our billet filler neck requires a standard GM overflow system style cap (3/4" depth).We recommend a 15 lbs. to 22 lbs. cap pressure.A higher pressure cap increases the boiling point.A higher pressure cap keeps the fluid in the cooling system, not the recovery tank. We use a cross flow design on our radiators to allow the radiator cap to be on the low-pressure side (cold side or water outlet) of the tank. Water drops in pressure as it is cooled
  • allowing recovered fluid back into the radiator during normal operation.On a down flow radiator, the top tank is always the hot side and is under constant pressure. Under sustained high RPM, this can force the fluid past the filler cap, out the overflow tube, and into the recovery tank even at normal operating temperatures. Our radiators use an aluminum angle for the mounting flange.This angle is TIG welded to the tanks.The aluminum angle has no mounting bolt holes. The customer determines the mounting pattern and location. This allows height adjustment for the radiator to center up to the water pump with the new engine location. This will also assist a desired height location if a body lift is to be installed. Our radiators can be ordered with or without a transmission cooler.The radiator has two 1/4" NPT fittings welded into the tank.We also include two 1/4" Male NPT x 5/16" inverted flare fittings.A benefit of the transmission cooler in the radiator is the heat exchange between the radiator and the tranny cooler.The radiator brings the transmission fluid up to a safe and constant operating temperature.

Advance Adapters got its start in Downey, California in 1971 with a single adapter mating a Muncie car 4-speed to a Jeep Dana 18 transfer case. Eventually headers, overdrives, motor mounts and linkage brackets were added to the offerings to complement their core adapter components. When interest in rock crawling spiked in the mid-1990s, Advance Adapters offered low ratio transmission swaps then switched gears into the ultra-low gear transfer case arena. Today, the company is based in Paso Robles, California and their engine and transmission conversions for Jeeps are in kit form and sold as individual components. Shop Advance Adapters Now
