  • Runs ice cold
Had for over a year now in my 1999 tahoe 5.7l . Had to mess around with the fittings a bit but it works great . Engine temp never goes a degree over.

  • Right Fit
The radiator seems well constructed. The radiator has the correct heater hose connection, transmission cooling line connections and oil cooler connections for a 1993 Chevrolet full size Blazer. so far, nothing cold be improved.

  • Top of the driver side keeps cracking, clearly a quality control problem.
Fits in 1988-1999 GM c/k1500 trucks. It's a little thick because it hold extra coolant (thus it's a triple core radiator). No plastic end tanks, so you don't have to worry about them leaking eventually. Oil cooler and atf coolers are built in but they use different fittings to attach to the oil cooler and atf cooler hoses (the new fittings are included). You will have to cut off the ends of both you oil cooler hoses and use their hose barbed fitting to make this work cause the aluminum crimped ends on those hoses will not work. The atf cooler lines also use different fittings and they are also supplied, but the lower atf line on the 1988-1999 c/K trucks is a steel hard line so you can't cut it off and you will need to buy adaptors to get the lower hose to work. The upper atf cooler hose can either be cut and you can use the hose barb supplied with the radiator or you can use hydraulic brake line adaptors. It cools a little bit better than the factory radiator and comes with a really nice radiator cap. It uses an alumnimu plug to replace the auxiliary heater core fitting which is way better than the rubber block off caps that the regular ones have to use. Teflon tape every threaded surface up really good and it won't leak. The new fittings use little black rubber o rings to seal up. Not bad at all. The only downside is that I've bought two of these radiators and they've both cracked in the exact same spot near the top on the driver side of the radiator in the finned section. Do not buy these radiators, they will leave you stranded. ... show more

  • Careful what you pay for or I hope your mechanically inclined
The media could not be loaded. The customer service was awful. They use a 20mm oil cooler line ports, problem is that NO ONE uses 20mm. Had to convert everything over to AN fittings. Most of which I could get here on Amazon. But the converting process cost as much as the Radiator itself. Don't get me wrong once that the radiator was converted and I knew everything was seal tight it works really really good but you better be mechanically inclined to install one of these interior Chevy pickup. I recommend 10AN Fittings and lines. That's 5/8. You can get them here on Amazon as well. You need the following off of Amazon if your going to convert from 20mm to 10AN. X2 20mm to 10AN male to male X4 10AN FEMALE to MALE 90degree elbow X2 3/8 MALE to 10AN MALE X2 10AN Hoses ( Your length may vary so please measure carefully) NOTE: As for Amazon regulations I am not allowed to disclose where I got my hoses from however they do sell a 10AN hose kit here on Amazon. But if you look up AN plumbing online I am sure you come up with something. OTHER NOTE: This actually works for a smalle block or big block Chevy mine wass 1991 454 BB, got the idea from a guy that owns a 1993SB. After that I would say you have to kind of watch your installation from factory OEM setting to this. there is some conversions that you have to do so do pay attention ,but I was able to put the factory shrouding back on and I was able to cut the rubber down a little bit for the factory mounts. ... show more

  • Don’t trust these radiators!
I bought a radiator from these guys for my 96 K1500 and it worked great until winter hit, then it had multiple cracks and was overheating in single digit weather with no functioning heater, only lasted a total of 8 months. Extremely dissapointed with the sellers as well, they were only willing to return 40% of the $280 I paid 8 months prior, that’s how much they value their product. I missed work, had to pay extra for a new radiator because the one they sold left me stranded, and had to replace it in snowy weather. They told me they can reimburse me 50% at most and they said it would take no longer then a day and it’s been about a week or so and still havn’t receieved whatever little money they were willing to send back, these people are about business not about selling you a good quality item and being understanding if what THEY sold you doesn’t work long enough to outweigh the price you pay!! ... show more
