A:BEST ANSWERHi Sky, I'm glad to assist you. That specific dimension data is not noted anymore since this is a direct fit vehicle-specific part. Just by entering the year, make, model, submodel, and engine size, the guaranteed-to-fit badge (a round green circle with a white checkmark) would show up and confirm 100% fitment.

Shopping for Buick Radiator

Despite being an upscale brand, Buick vehicles are reliable and perfect to use as comfortable daily drivers. However, some faulty parts may ruin your Buick’s performance and driving experience. One of the most stressful problems you may encounter with your Buick is a bad or malfunctioning radiator. It’s a key component in your cooling system, which expels heat from coolant fluid that circulates throughout your engine. Your radiator is usually made of durable metals, but it’s still prone to wear because of its constant exposure to coolant fluid and extreme temperatures.

It’s important to keep your Buick radiator in good condition. If not, you may have to deal with the troublesome symptoms of a bad radiator, such as coolant fluid leaks, coolant fluid discoloration, and shifting problems. A bad radiator may also cause your heater to malfunction, which can greatly affect overall ride comfort. A faulty Buick radiator may also cause your vehicle to overheat frequently, which may lead to further engine damage and expensive repair costs.

Don’t drive with your Buick if it has a bad radiator. Luckily, you can replace it as soon as possible by getting a new Buick radiator right here at CarParts.com. We have a wide range of Buick aftermarket parts to help fix and restore your vehicle.

All of our Buick aftermarket parts are on hand and shipped directly from our strategically located warehouses, so you can receive your order in less than a week.
