The way I use this product probably is different than the most common usage. The little radiator is well constructed, packaging is nice which means that it is in perfect condition when you take it out of the box. I do not use the attaching parts, but they are of good quality. I have put several of these radiator to the same purpose and they have all survived well. GOOD STUFF.

Bought these before for my vehicles. Put this one on a Silhouette and by-passed the in-radiator cooler altogether. Haven't put a thermometer on it to check temperature drop, but transmission is running smooth in 96 degree temps. Pair it up with an in-line transmission filter for a clean cool combo. Heat and slamming an automatic into reverse at 30 mph are the main destroyers of automatic transmissions. This will take of one of those problems.

This fan was exactly what I needed to give an A/C condensor better airflow. It fit perfectly between the radiator and condensor of a modified truck with add-on A/C. It's cool (no pun intended) that it is reversible. Just switch the 2 wires, reversing the polarity to change the airflow direction. This way the fan can be used as a pusher or a puller. It sucks, it spins, it blows. It does everything you want a fan to do. It comes with all mounting hardware needed. I was fortunate to have a prewired relay in the vehicle since this fan didn't include one.
