Denso 221-0508 Radiator

Perfect fit.

I recently had purchased a cheaper brand radiator on Amazon for my 1999 4Runner which was half the cost. However, after I received it, I realized it was half the cost because the manufacturer had skimped and made the actual coils thinner (from front to rear). So basically that radiator wouldn't hold as much radiator fluid, thus making it harder to cool off your engine. It was also as light as a feather as it was otherwise made with so much plastic instead of metal. So I bit the bullet and bought this Denso brand radiator, which was twice as much. But I'm glad I did, because it was an OEM quality, thicker coiled radiator. Others have said on here that when they received their radiator from Denso, the overflow nipple was busted off. But mine was packed very good, and the overflow nipple was intact. The only thing I didn't like about this radiator, was there were no machined screw holes for the fan shroud. Where those holes were, Denso put nut clamps so that the bolts could be screwed through the holes and into the clamps. Not a big deal as it worked out fine, I just would have liked them to have been machined screw holes, like the machined screw holes where the radiator mounts to the vehicle frame.

Fast shipping, no damage to packaging. Direct fit, was installed in about an hour, and most of that was allowing the system to drain. Over 500 miles driven since install, no issues. Recommend for other 3rd Gen owners.

It fit in my 98 4runner 2.7 with no issues. No shipping damage. Works perfect. It's held up for 3500 miles and 4 months so far. I've done a couple 200 mile trips which is pretty far for me and no leaking or overheating. My original radiator actually kinda surprised me because it didn't leak much until I took it about 70 miles on the highway with no cell service and I get out and it sprayed coolant all over my driver wheel well, luckily I had a couple jugs of coolant and plenty of water so I made it home, ordered this a couple days later though lol. Seems like a quality part, I will update if that changes.

I was really hoping that this radiator would work due to it being a Denso rather than the generic ones carried by Autozone or Advanced Auto. After all Denso has a great reputation with electronics and the factory radiator is supposed to be somewhat related to Denso. Anyhow DO NOT BUY THIS GARBAGE!. Radiator arrived all sloshed around due to the foam not being placed properly and worst of all after installation I noticed the nipple in the fill spout was broken! (yes I should've read prior reviews). Installation wasn't without issues. The bottom is too wide to fit through the frame so both the sides have to be bent flat (or take the fan off). This is definitely not a first time fit as it states. I ended up purchasing one through Advanced Auto and it was the exact size as the factory except the holes would not allow the fan shroud to fit correctly but I have run it in the past without one so it doesn't matter much. All in all do not buy this radiator its just gonna cause more grief than help. In fact being this is the third car part defective from Amazon I DO NOT recommend buy car parts from them (big ones anyhow). Go to other well known sites.

I wish they utilized the same drain plug design as the original. Was flushing out the system and had to experience fluid shooting out all over the place several times because the plug doesn't have a setting like OEM where you can unscrew to a certain point where it will drain normally. The plug is shorter than OEM and you have to unscrew the whole thing in order to drain the system. And if you're not ready it, the flow comes shooting out straight towards the back before it slows down and drains downward. If you're flushing your system, I recommend having a coolant kit with the funnel for the radiator. Use the funnel to direct the flow into a pan/bucket when you remove the plug. You'll still experience some spillage as you're removing the plug, but it can be minimized. Otherwise, mine came undamaged and was easy to swap in.

Previous reviews almost scared me into not purchasing this radiator, due to reviewers saying they received theirs with broken overflow outlet on the fill neck. Mine came in perfect condition. It was packed with a decent amount of cushion in the form of foam padding and styrofoam. The cooling fins were not damaged at all. I was worried that UPS was gonna beat up the box and deliver a damaged radiator but It all worked out great. Direct replacement and perfect fit for my 1998 3rd Generation Toyota 4Runner, 300K+ miles. Good price too, right at $100!
