Before we filled our radiator back up, we measured the coolant performance of the mixture that came out of the radiator. We were pleasantly surprised to see that our car’s OEM factory fill Dodge 3-Year Green OAT (Organic Acid Tehnology) coolant has been flushed and upgraded to the better performing Mopar 5-Year Red HOAT (Hybrid Organic Acid Technology) type coolant.
We replaced the factory 17lb radiator cap with a 16lb ASP Radiator Cap from ROE Racing which has a sacrificial anode that stops Electrolytic Metal Erosion (EME) inside the cooling system. The cooling system carries a slight positive charge which can erode the aluminum components in the cooling system from the radiator to the block itself. This sacrificial anode is hung from the radiator cap and is made of a softer metal which the EME attacks first. This extends the life of all metal components in the cooling system and is a great investment.
With our new ASP Radiator Cap installed, we replaced the clear hose with a new Semisoft 5/16” ID (with a 9/16” OD) High-Temp Silicone Rubber Tubing from McMaster-Carr which has a -94*F to 392*F operating range. Part 5K29. We used a constant-tension spring band hose/tube clamp for 5/8” hose (Part # 7329K11) and a screw clamp to ensure a tight fit over the metal hard lines.
