GM Genuine Parts Radiators are designed, engineered, and tested to rigorous standards, and are backed by General Motors. Radiators are heat exchangers, typically located in the front of the vehicle where air can flow through the fins and dissipate heat. Modern radiators are made from aluminum and plastic, while older vehicles used copper and brass. These radiators are designed to be corrosion resistant with optimal heat transfer characteristics. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

GM replacement radiator–fits like OEM because it is.
i purchase this radiator to replace the original one (whose upper plastic tank had cracked). the original lasted 15 plus years, so i went back to OEM. the amazon price was about $150, very reasonable. came securely boxed, and was undamaged. fit perfect, only problem was the that i had to sand down one of the transmission cooler lines to allow it to fit in the corresponding fitting. i suppose it was because of manufacturing tolerances–took me a while to figure it out. ordered a new radiator cap and lower hose at the same time. was very time consuming to replace—had to remove fan, fan shroud, grill, battery-box brace, and cross-member support to get the radiator out and the new one in. also, both the new, and old radiator had no provision for a drain fitting–so the lower hose had to be removed to drain coolant–very messy. GM could have done a better job engineering the car for easier replacement. took about 4 hours total to do the job. also plan on 2 gallons of coolant (1 gallon if re-using the old coolant). check you tube videos for step-by-step guide.

Great Price, great product
OEM parts are always better. I gambled and purchased a Used- Like New radiator. I received in a short period of time and it was an exact match. The price was less than half of the original. Thanks

How to replace the radiator on a trailblazer w/ rear ac
Got this as an OEM replacement for my 02 chevy trailblazer. Product was an exact match for my previous radiator. The replacement can be tricky for these trucks but instead of messing with the fan clutch which can be a major pain to get off (especially without certain tools) I would recommend taking most of the front clip off instead.It total it took me about 40 minutes to replace it.1. Remove all the bolts that connected the radiator to the fan clutch and pull loose the ac lines running along the fan clutch.2. Removed the grill (several clips you pop out)3. Remove the headlights (two clips you pop up then disconnect and pull out)4. Remove the cross bar above the radiator5. Remove the hood latch (only 1 bolt but do not disassemble just move to the side)6. Remove the plastic frame piece that holds the headlights and grill in (might help to remove the bumper first but I just pried it loose)7. Remove the upper and lower hoses to drain any coolant from the radiator8. Pull clips from the transmission lines going into the cooler and pop them lose (it might take a little bit of force but they honestly just slide out)9. Pull the radiator out but the lower rad hose connector will get caught on the fan clutch shroud as it does get in the way so you will need to wiggle it and maybe pry it with a screw driver past the shroud.Putting it back together is just the reverse. Make sure to fill the radiator up with coolant again and replace any lost transmission fluid.
