Review on 🌡️ Enhance Cooling Efficiency with Koyorad HH021687 High Performance Radiator by Michael Schafer

Received this based on feedback on using this radiator in Titans 05 and later. Since the Nissan Titan has a very similar engine configuration to the Armada, I think it would be a good choice. Well that's a good decision. I installed it on my Armada 06 and it was an easy install. I also renew the upper and lower hoses. Be careful! Warning. This type of cooler can only be installed IF YOU HAVE BYPASS or a transmission aftercooler. This unit does NOT have an internal transmission cooler. you have to bypass the transmission oil lines and install an additional transmission oil cooler, what else! I have noticed that my experimental gauge reads lower than my original cooler!. not much but noticeable on the gauge, I can keep the engine idling in the sun for over 60 minutes without the temptation gauge going halfway in Southern California weather. I don't tow, but I run the engine pretty hard on highway trips and I think this will keep my engine purring for a while. YUP, the tempt sensor was just bound between 1/4 and 1/2. never did that in the old RAD
