🔥 Mishimoto MMRAD-RAM-03 Performance Aluminum Radiator for Dodge Ram Cummins 5.9L/6.7L 2003-2009: High-Quality Cooling Upgrade! Review

I figured I'd get a well made and quality heatsink; However, I took it out of the box and it was of poor quality. I do not recommend. You will get better quality from other radiators on the internet. Don't waste money.

I had to fix the drain plug at the bottom. Lick from the start. Radiator cap does not fit (Dodge). It's like a Honda cover. I will never buy their products for any car. The guarantee is a nightmare.

didn't notice any temperature difference between mishimoto and standard heatsink well built heatsink fits well but not worth money in my opinion

Straight cut, looks good and dissipates heat well. Be sure to order silicone tubing. I didn't, and the extra pressure ripped off the top tube and all the liquid came out. Silicone hoses installed and now everything works perfectly.

I figured for that price I'd go with something that's made in the USA, or better yet, well it turns out to be another Chinese made radiator (hidden in the corner of the box). I won't pay a premium price for an "efficient radiator" from China and I'll be right back.

Temperature seems to be fixed. The problem is, but the build quality isn't the same. The stripped flow tube and excessive welds everywhere make me wonder what else could come. It doesn't look like a 100.00 radiator!

Does not use a standard American car radiator cap, the coolant recovery nipple was much smaller and there were no bushings to match what is in the truck. If you try to remove it and insert a larger one, it will just cut off. There is no support for the transcooler tubes, they have to be bent away from the radiator bracket to keep them from chafing, but there is nothing holding them like the original radiator, so the vibration will cause the radiator tubes to crack over time.

To be honest, it's not cheap. Is it expensive; However, if you need to replace an old radiator, this is a good option. I wanted to install a high-quality part on my truck and simply rebuilt the engine. Important was the fact that mishimoto offers a lifetime warranty on their product. It's solid aluminum, which means no plastic can break. Even the neck that the radiator cap sits on is also made of aluminum. Very good product.

Packaging needs improvement. The top square tabs for the support bracket have been bent. We had to reshape them to fit the rubber bushing in the tongue. Great concern if this leads to a problem with fatigue in the future. The fit in the 2004.5 3500 was correct. We didn't have any major issues with fit and finish. So far performance has been a slight improvement (5-10F) over a factory measured cooler. In August, a truck drove smoothly from Texas to Colorado. The truck has not been loaded since…
