    • Perfect fit in my 2000 GMC K2500
Review Image by steven p. steven p.
Fit perfectly. I did need to use the transmission cooler adaptors that were supplied. Some reviews noted engine oil cooler leak... Be sure to replace the O rings on these connections...grab them off the supplied adaptor fittings. Transmission cooler connections are flared. WARRANTY NOTE: The Spectra Amazon store notes a 2 year warranty ONLY WITH PROFESSIONAL INSTALLATION. If you do it yourself, you only have the Amazon 30 day return window. ... show more

    • fit like OJ Simpsons glove
Perfect fit for our 2000 chevy 3500 truck. bought for $128. It was a return with zero blemishes! Did have to use 2 of the four adapters that came with it. Also, my truck does not overheat anymore! It fixed an old overheating problem due to a clogged radiator.

    • Cool On My Stool...
I tend to overdo the research for items when it comes time to replace/repair. These Amazon reviews have changed the old way of guessing & hoping an online order will suffice. But I still tend to research the researchers reviews...a good way to waste a lot of time. Knowledge is king and one can be further educated by sifting through the reviews. I was comfortable buying this <a href= "https://www.amazon.com/dp/B000C7RZWC/ref=cm_cr_ryp_prd_ttl_sol_0">Spectra Premium CU1693 radiator</a> for my 1999 C1500 Suburban 2WD and confident that it was the proper radiator to fit my application. First noticed my coolant overflow tank on the passenger side firewall under the hood would not hold coolant. Checked to make sure the plastic tank had not developed a crack in a seam or a hole...no such luck. I had already done the 5.7's famous intake gasket replacement as well as the factory "quick-connect" that tends to go bad. So my trusty 'Burb's radiator had begun to leak a small spot on my driveway. Left front corner of the vehicle...it was kinda hard to detect exactly where the coolant was coming from but with my well-reviewed LED super bright hand held spot light, I was able to see the green coolant seeping from a very small hairline crack in the left (driver's side) plastic tank about 2 inches below the top cooler fitting. Looks like a big job but it's not really. I'm no pro but I am thorough and I tend to help friends and family that are convinced they cannot pull off mechanical tasks such as this for whatever reason. I am still invited to family beach gatherings each summer and I still have a friend or two left so I must be doing something right. Only thing I could add to the already good reviews is to grab a can of PB Blaster or similar spray lubricant (Kroil is the best but not always easy to lay your hands on at common parts houses). Squirt around the fittings for the oil coolers lines and the auto transmission cooler fittings...top & bottom, a day or two before doing the rad replacement. You can install this radiator from the top mostly but I went underneath to remove the lower radiator shroud so I could clean everything out really well and do a little inspecting in the area while the radiator was out of the vehicle. On my almost 20 year old 'Burban, there are 2 lower shroud screws in the center portion of the shroud that had rusted to the small clips pretty badly. A squirt here on these 2 screws may help get these out easier but they may be <i>rusticularly</i> welded (new word for your word of the day, Bill O'Reilly...use that if you like). If they're like mine, you will have to use a little muscle to snap the screws and replace with new ones. No prob...the handy dandy "HELP" rack at your local parts place has clips and screws if you don't have a collection in your coffee cans on the garage shelf. Or simple nut/bolt with washers will suffice or even a couple plastic ties cinched up tight will hold that section as long as you have the other screws/clips in place. My search for radiators included the text (No Oil Cooler Fittings) and that threw me off. But be assured, this Spectra Premium CU1693 rad DOES have fittings for both oil & trans and they are located precisely where all four lines will connect. As noted in other reviews, there are adapters included, if your application requires them. Support your lines while applying force to loosen or tighten. New clamps are not expensive if you don't reuse the old ones. If changing these, be sure to position the hex head/screw slot on these clamps in a convenient position to get at 'em in the future. Easy peasy...now I am once again cool on my stool with my knees in the breeze. ... show more

    • Built well, works well & continues on
Bought to replace a clogged up original radiator for my 99 Suburban K1500. The original with the rest of the entire coolant system had suffered from the "red" coolant breaking down. After working on replacing the rest of the coolant lines, jackets & water pump the radiator also needed replacing. Ive used Spectra brand (same or similar to others, just a name) for my other 3 vehicles without fail & this proved to be nothing less. There was some difficulties with the adaptors but I didnt need them as my version of cooler lines for the oil & transmission were a direct fit. I only needed to use the seals, unfortunately mine only came with 2 seals making me have to use plumbers thread tape for the transmission lines. So far coupled with an almost entirely new coolant system has proven itself well. ... show more

    • Lasted little over a year
Bought in april 2019 and installed fall of 2019. Has been slowly leaking since January 2021 and now drops half the coolant overnight forcing me to replace so I figured I'd go back and review. Leaking from where the tank meets the core halfway down so its clearly a manufacturing issue. This is on my personal truck that sees maybe 6-7000 miles a year so its not had a lot of hard miles. I am 45 years old and have been working on my vehicles, building race cars, and have done a classic boat restoration so I'm not someone who just attempted radiator swap to save some money. I pay special attention to every detail as the last call I want to make is for a ride from the side of a road. I have had good luck in the past with spectra radiators but that was clearly a different time back before everything was farmed out to china. I have had similar issues with OEM parts lately which makes me wonder if its time to buy into the disposable car payment every month. Just really sad ... show more

    • Thinner updated design.
My old radiator core was 2.25" thick. This one is 1.25" thick. This is an updated design. The 2.25" ones don't exist anymore. I tried finding one through multiple local parts stores. Other than that it fits and functions perfectly. Comes with 4 adapters for cooler lines. I only had to use 2 of them on the Trans cooler side. 1999 Suburban w/trans and oil cooler. ... show more
