🌡️ High-performance Denso 221-3137 Radiator for Improved Cooling Efficiency Review

Don't buy from this supplier…… it leaks, this is the second time I've installed this product, I returned the first one because it leaks , I installed a second one and it leaks....do not buy this product

I really wanted the original cooler for my 1998 Tacoma 2.4L single cab manual transmission and it fitted perfectly, just had to replace the side brackets with the original ones and they fit perfectly. also removed transmission lines because there is no automatic transmission

Fits great, minor issue is the mounting screws are not returned as this replacement is designed differently. I recommend buying 4 new screws that are slightly longer than the current ones so they can hook into the threads of the mounting clips. Bolt size 8 x 1.25mm. Otherwise great cooler!

Machined on a '96 Tacoma 4 cylinder. Make sure you measure before ordering. Very easy with a measuring tape. New bolts are required as the threaded tabs are farther apart than the OEM. 4 for fairing, 4 for radiator. Both sets come in different sizes, so get them in time. Luckily I had spare parts lying around.

Really disappointed with the packaging or delivery, it came a little dented on the transmission hose flanges and frayed from a big hole in the box, one flange was unscrewed somehow . I spent $100 on an OEM product and thought Denso would do well. I was wrong, I should have spent the extra $30 on a Mishimoto.

The radiator arrived well packaged. Fits right on my 2000 2.4 liter Tacoma. In these fit 2.4 liters. For the 2.7 and 3.6 liter versions you need a slightly longer one. The only problem was that the mountain mount that came with the kit is different and the mounting bolts from the old radiator don't fit (they aren't long enough). You can buy longer screws or do what I did: remove the mounting brackets from the old OEM heatsink and use them on the new one. It worked great.

Installation was excellent. But as others have mentioned you need to get longer screws, they don't twist when you screw them through the core support. Installation was easy, took about 45 minutes to remove the old one and install the new one, a few minutes to add new fluid. I currently have about 185 miles and no problems. Other than that I haven't had any issues with the other one, but as it was a 1999 original OEM radiator I figured it would probably be a good idea to replace it as it will be
