The website listed this radiator as a direct fit. Upon removing my old radiator from my 1987 chevrolet truck, I discovered that my radiator was 19 inches tall, not the 17 inches that this radiator measured. Also, the mounts on top of the radiator did not match up in regards to their mounts, even if it had been the right height. If you decide to buy one of these, I highly recommend that you measure the core of your existing radiator first, and that you prepare yourself for having to modify the mounting brackets to allow this radiator to fit...... I sent it back to Advance.

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.

Confused, I bought this radiator because when I inputted Vin # it stated the radiator I bought was a fit. Yet radiator doesn't fit. Glad and satisfied I got a return, though, can't wait to find the correct radiator. If they had it, yes, I would buy from this place again.

I ordered this radiator to replace the OEM product in a 6.2L diesel pickup. The shipped radiator is not as described or pictured. What is now shipped is a plastic tank/aluminum cored radiator. Very, very overpriced for that style of construction. The original is a Brass tank/Copper core with 3 rows. This one only has 2 rows in the core. It looks like it would fit, but not with the same performance as the original. Judging by one of the reviews, they must have in the past shipped the better style. Now they are shipping the cheaply made type. I returned this unit without issue. For a similar price, I ordered another radiator that was the heavy duty, all metal type. Way better radiator than the cheap plastic/aluminum one.

the radiator is well built and is the old type-copper\brass construction. but will not work on the 1985 chevy vouge II for which i purchased it. this radiator is about 6" to wide and would have to be heavily modified to fit the rv application. I would recommend this product if it fits your application.

Q&A as well as Advance's manufacturer documentation claims that this is Copper and Brass. Ordered this only to find it is Aluminum and Plastic. Not what I want for a Classic Vehicle especially after my son's plastic tank catastrophically failed with a foot long split in a plastic tank. Ordered a different brand from a competitor, it looked exactly the same. Tried fitting the 'other' into my '68 GTO but didn't fit right. Eventually determined that the tanks are not installed squarely on the core, thus placing the top 1/4" in the wrong location. The exposed Core area is a parallelogram, Not a rectangle. Gave Advance a 2nd chance. Took my square with me this time and found Advance radiator also not square. This would work if required but only by shaving and shimming the radiator mounting pads. Instead, I went ahead and soldered a couple small cracks in my Metal tanks.

While it does work, if you read the Q&A section it says "This Ready-Rad Radiator - part# 433348 has a copper brass construction and the color of the tank and core is black. The tank material is metal." It's actually plastic and aluminim and the core is silver. I'm restoring an old car and this isn't what I was looking for.

Fit in place of my original 34 year old radiator perfectly. 1987 Chevy 3/4 ton with 5.7 and manual trans. There are two sizes- 17" and 19". Looks like a few other reviews ordered the wrong height. This ones working great so far in my old truck. cooling better than the tired and leaky old one. For the price I'm happy. It fits and works.

Has plastic tanks. These are complete trash...everyone knows this. Advertised as meeting or exceeding OEM specs. Well OEM specs on my 1987 GMC 1500 truck was for a radiator that has metal tanks on it. So you're basically getting deceived on one hand and lied to (by omission) on the other. Now I have to pay $$$ to return this junk. Absolutely NEVER buy parts online unless you're ready for some surprises. And the radiator hose I bought from them was thinner and softer and flimsy'er than the one I was intending to replace....and absolutely no internal support for such a cheaply made hose. 1 Year (chump worthy) warranty. Pathetic....garbage. I'll never buy their FLIPPO-JIPPO junk parts again!!!! Beware buying online.....I bought their best (HD) and it's the cheapest quality trash I've ever seen....EVER! Geeze.....

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.

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...)

The guys comment above mine must be a joke or the guy don't know how to measure. The spec's say the core width is 32mm which is right around 1.2 iches(1.25984 to be exact) and is gives no size for the header/tank size.
