    Installed this radiator on a '82 C20. The radiator sits about 1.5" too high for my truck. I had to notch a bit of the aluminum on the radiator, notch the radiator brackets, and remove the urethane mounts and replace with pieces of flat rubber. I expected to make it fit. The unacceptable part is that the radiator does not come with a regular petcock. There is a brass plug installed. I bought a traditional petcock, but I could not remove the plug. It's seized in there. Whoever installed it screwed it too tight, used lock tight or messed the threads up. I did not want to risk cracking the plastic side of the radiator. So I will have to remove the lower hose in order to drain the system in the future.

    Works, truck runs 180°, no leaks. Cools just fine, but core is way thicker than the original in my 90 suburban. The one advance sells that is of the same thickness as mine is only a one row. My original was a 3 row. A one row with my ac running in the florida summer is never going to keep my truck cool enough, so had to get this one. Heavy modifications made to upper core support mounts and the shroud to make it fit. Width and height were the same though.

    Bought for 1967 Olds 442 with auto trans. The radiator hoses fit ok, the trans cooling lines fit ok. Has a port near radiator cap for a temp sensor. Also looks like a port for trans cooler temp. It only has two core tubes but the tubes are twice as wide as the OEM so I guess it would compare to a four core. The end tanks are made of plastic like newer style OEM radiators. The bad part about the radiator is the OEM cradles at the top and bottom had to be pounded flat so it would fit and it was still very tight. If your looking for a drop in radiator with no modifications then this is not for you.

    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.
