Is Your Uplander's Radiator Failing?
A bad radiator can lead to serious engine trouble. If you notice any of these signs, it's time to inspect your cooling system. Ignoring them can cause your engine to overheat, which may lead to expensive repairs.

- Coolant Leaks: Finding puddles of green, orange, or pink fluid under the front of your van is a strong indicator of a leak. The most common sources of leaks on an Uplander are the radiator itself, or the hoses connected to it.
- Low Coolant Level: Frequently needing to add coolant to the reservoir means you have a leak somewhere in the system.
- Visible Damage or Corrosion: Look for bent fins, corrosion, or cracks on the radiator's plastic side tanks. Over time, the plastic can become brittle and crack, causing leaks.
- Steam from Engine Bay: If you see steam, pull over immediately. This means hot coolant is escaping the system.
Known Issues for the 2005-2009 Chevrolet Uplander
While there are no specific recalls for the radiator on the 2005-2009 Uplander, some related issues are worth noting. General Motors issued a Technical Service Bulletin (TSB 07-06-02-006E) for some 2006-2007 Uplanders with the 3.5L or 3.9L engines concerning coolant leaks from the crossover pipe gaskets, not the radiator itself. However, the most common failure point on these radiators is cracking of the plastic side tanks where they are crimped to the aluminum core. Coolant leaks can also come from aging rubber hoses or loose hose connections.
Choosing the Right Aftermarket Radiator
When replacing your Uplander's radiator, you don't have to buy an expensive part from the dealer (OEM). Aftermarket parts can offer similar or even better quality for less money. Aftermarket brands are designed to fit and function like the original part. Here’s a look at some available brands:
- Denso: Denso is a well-regarded OEM supplier for many car brands. Their aftermarket radiators generally have a good reputation for quality and fit, though some users note that the replacement parts may differ from the original factory-installed Denso parts.
- Spectra: Spectra is a popular aftermarket brand. While some users have had positive experiences with good fit and performance, others have reported needing warranty replacements after a couple of years. Quality can sometimes be inconsistent.
- CSF Radiator: CSF is another option, though some mechanics report issues like wrong parts being in the box. Their plastic tank radiators are generally considered okay.
- APDI, Global Parts, One Stop Solutions, Onix: These brands are typically more budget-focused. They can be a good value, but quality and longevity may not match premium aftermarket or OEM parts.
Pro Tip: When you replace the radiator, it's a good idea to also replace the upper and lower radiator hoses and the radiator cap. These parts are inexpensive and wear out over time. It's also a good time to flush the cooling system and refill with fresh, correct-spec coolant.

Frequently Asked Questions

What's the difference between an OEM and an aftermarket radiator?
OEM (Original Equipment Manufacturer) parts are made by the same company that supplied Chevrolet for the factory. They guarantee a perfect fit but are more expensive. Aftermarket parts are made by other companies to fit your vehicle and are usually more affordable, with a wider range of quality and price points.
What type of coolant should I use in my 2005-2009 Uplander?
