Product Information

Product Details
Part No. 431321
Warranty Details (Limited Lifetime Warranty)
A global leader in the manufacture and distribution of aftermarket cooling products for automotive, heavy truck, and industrial applications. Specialized in the production of OE-quality Radiators, Condensers, and Charge Air Coolers for US and international markets, covering over 10,000 part numbers worldwide. Reach Cooling is headquartered in Miami, Florida, with additional distribution centers in Los Angeles, California and a manufacturing plant in Shanghai, China.

Product Features:
  • Our B-type tubes feature central reinforcement to provide greater tolerance to pressure. Stronger tube design means drastically reduced probability of tube failure.
  • Our deep extrusion header provides a stronger tube to header joint which is more resistant to the effects of vibration and thermal tube expansion, virtually eliminating tube to header leaks.
  • Our fin edges are folded for increased stability and heat disbursement properties.
  • Our included "multi-fit" attachments allow one radiator to cover multiple vehicle applications without sacrificing OE fit. This results in wider vehicle coverage with substantially less inventory.
  • Thermal expansion cuts allow for longer life and reduce failure rates by allowing improved core expansion and contraction during normal heat cycles.
  • We design and manufacture all our radiators to meet or even exceed Original Equipment specifications. We take pride in producing the most reliable replacement parts in the market.
  • We use longer header tabs for increased pressure resistance. This reduces the potential for tank to header leaks.

Ready-Rad does the job!
I keep my autos forever so I have had the oppertunity to use several of these rads. They are better than OEM especially on older vehicles as they are a more advanced product. I have never had any problems with fit or with the combination of materials used in their manufacture.

Fits well, needs some attention.
The fit of the radiator was perfect. The transmission cooler quick-disconnect fittings leaked badly. I solved the problem by brazing 3/8" brake line to the old fittings and cutting the quick disconnects off. A short piece of rubber hose connects the lines to the cooler. I checked the original fittings after I removed them, and the lines were installed correctly. To be fair, the original fittings weeped, so they're not the greatest design to begin with. But everything worked out well in the end, and I'm satisfied.

Not the best of engineering
Verified Buyer -
The upper passenger-side port on the radiator was slightly smaller than the factory hose, it had almost no flare on the end, therefore the factory spring clamp did not hold well, antifreeze leaked without the engine even running. To rectify - used a small worm gear clamp & Permatex. The trans cooler line fittings on the radiator were the worst part as they stood off the radiator about 2 inches. Factory fittings stand-off about 1/4", big difference... Could not use factory fittings in the replacement radiator, threads are not identical. At this point with the radiator in the vehicle, having REMOVED the upper trans cooler fitting from the radiator, I had to work to insert the upper trans cooler line into the fitting, then work to get the fitting threaded back into the radiator. The lower trans cooler line was not as bad because there was more room to work with it. The upper line is short, tight and bends 180°, there is little working space between it and the power steering support bracket. After two days in operation, so far, no leaks on anything.
Great product, wrong application
Verified Buyer -
Correct radiator, wrong transmission cooler fittings. Due to everyday driver, had no choice but get competitor part due availability. Increased cost 35.00!
Bottom Line Yes, I would recommend to a friend
Ready-Rad works!
Verified Buyer -
love this product so far. Old radiator was difficult to take out. just make sure you take the brackets from the a/c cooler on the raditor off. And get a quick disconnect tool to remove tranny lines from the old radiator. I took off the drivers headlight and battery box brace to get better access to the top radiator hose.Once I figured that out it was pretty straight foward. YOU DO NOT NEED TO REMOVE THE FRONT BUMPER. Other then that My car runs cooler then the OEM radiator. Very impressed.
Bottom Line Yes, I would recommend to a friend
