Review on Efficient Cooling: Spectra Complete Radiator CU1290 for Optimal Engine Performance by Daniel Mandal

This cooler comes very close to the original. I've only driven it about 20 miles since installing it, but no leaks so far. It was well packaged and delivered without damage. I removed the lower radiator hose from the thermostat housing. This greatly simplifies the work. It was easy to replace. Note that the screws provided with this replacement heatsink are unusable as they are too long. I tried to see if I could use black parts to somehow get the screws to work, but I gave up. Screws in the less accessible bottom locations and used zip ties in the top holes until I could get a replacement from my local orange hardware store. If anyone wants the specs of replacement bolts, they are M6-1.0 x 16mm. As others have noted, although there is one in this picture, this heatsink does not have a cap. It doesn't matter much. My original cap is probably better than the one they ship anyway. My only real complaint right now (besides the useless screws) is that the radiator neck doesn't allow for the burrs on my cap. be straight (level with the vehicle) when fully tightened. If you have obsessive-compulsive disorder about mechanical things like I do, this is annoying. One has to wonder why Spectra could not reproduce this detail correctly.
