Bought this for my 1979 k10 fits perfect runs cool
Perfect fit and motor runs so much cooler than the OE radiator set up.
Not an exact fit for my 1984 GMC Suburban, measured stock Rad before purchase and this one is about a 1/4 wider, modified the shroud slightly and it slid right in. Anyone with common sense can make it work in this application.

Hard to rate something that is newly installed, BUT, Good fit and finish, hope it lasts a long time !
The first radiator we ordered said exact fit but did not fit. The second one was perfect and worked like a charm.
Radiator is super light and cools my small block 400 well.

Not a very OEM fit. Had to make modifications to the shroud and the rubber brackets inside. These are a one row radiator.
This was purchased for a 34-year-old Chevrolet truck. If you measure your radiator core height and width carefully before ordering, surprise! The replacement will fit. There are four or five different possible sizes depending on your application, and based on other reviews a lot of people order the wrong part and then blame the manufacturer. The radiator is well-constructed and arrived in good condition. Quick and easy job. For the people who complain about this radiator having plastic tanks, well... that's what they make 'em out of these days. Engineering plastics are significantly better than metals for many applications. Greater flexibility and no corrosion, for example. This radiator is a good value replacement.

Appears to be a decent piece, but it definitely does not fit the stock radiator mounts w/o some modification to the radiator core support.
I bought this product for my 1969 GMC 2500 truck with small block 350. This truck had the original 3 Core radiator which was leaking and freighted with sludge. The new radiator is less than half the weight. If your truck has the 3 core radiator mounts you will need to trim the rubber to get this to fit, or order the 4 core radiator mounts from big block trucks, or trucks with tow package. To my knowledge almost no new repop radiator on the market fits the 3 core mounts without some modification. I plan to order the 4 core mounts for the top and replace the current trimmed setup, but it looks factory as is when in place. The only thing I do not care for (which is common on most new radiators) is the lack of metal insert in the fill neck, and the plastic drain plug. I did not experience any leaks on initial test. Although I have not road tested the truck this is a 3 core radiator and being aluminum / copper instead of steel / copper should offer some slightly better performance than 40yr old technology. Bottom line worked, and price was cheap, but as with any old vehicle some modification is neccissary.
This radiator is constructed of aluminum and plastic, as most are in this price range these days. I had to fabricate mounts for the radiator, but that wasn't too much trouble nor did it come as a surprise to me. The bad radiator I removed from the truck was not the original or an 'exact fit replacement' radiator. I have no idea what vehicle the bad radiator came out of or was intended to fit. The new radiator is functioning well. A 3 star rating on this website is described as: "Average, Ordinary", which fits the bill for this radiator IMO. Oh yeah... a cool thing about this radiator is that there is a threaded brass female fitting (it comes plugged) in the right-hand tank that can be used to mount a temperature probe for use with an electric cooling fan. In this case I didn't need that feature but it is a cool option to have.

Inlet was 1.5" instead of 1.75" it is made to fit all GM models but doesn't fit anyone correctly. U.S. Radiators is were I ended up buying my last one and they are custom made with all your factory specifications required (4 speed, Air, Etc...)

1st radiator was defective looked opened and returned. Had a return sticker on box. you cant beat brass they say aluminum cools faster try to find someone to fix it or a plastic tank. I'll stick with brass you can repair it. durabilty cant beat it

The only cOmplaint I have is the hose inlet was bent or I would have rated it a 5. Noobvious damage to outside box but also nopaint scrapes on radiator so I am unsure atWhat point it was damaged. Easy to bendback into place. Appears to be a good product. [...] Happy so far
