Dodge Grand Caravan Radiator Replacement Guide (1993-2001)
Everything you need to know before buying a new radiator for your 1993-2001 Dodge Grand Caravan.
- The most common failure is cracking of the plastic side tanks, leading to coolant leaks.
- Before replacing the radiator, confirm the leak isn't from the separate plastic 'Y-pipe' heater hose connectors.
- High-quality aftermarket brands like Denso, Spectra, or CSF offer excellent value compared to expensive OEM parts.
- Plan to replace the radiator cap, thermostat, and hoses at the same time for a complete cooling system refresh.
Is Your Grand Caravan's Radiator Failing?
A failing radiator in your 1993-2001 Dodge Grand Caravan will show several clear warning signs. Ignoring them can lead to major engine trouble. Be on the lookout for these symptoms:
- Engine Overheating: The most obvious sign. If your temperature gauge is creeping into the red, your cooling system is not working correctly.
- Visible Coolant Leaks: You may see puddles of green, yellow, or pink fluid under the front of your van. The most common failure point on these radiators is the plastic side tanks, which can crack with age and heat cycles. Check for wet spots or stains on the radiator itself.
- Low Coolant Light: A persistent low coolant warning on your dashboard means the fluid is going somewhere. If you're not seeing a puddle, it could be a slow leak that's burning off before it hits the ground.
- Sweet Smell: The smell of hot antifreeze is a sure sign of a coolant leak somewhere in the system.
A Note on Other Common Leaks
Owners of these minivans should be aware of another common coolant leak source: a plastic "Y-pipe" heater hose connector. This part can crack and drip coolant onto the hot exhaust, causing a smell and coolant loss that can be mistaken for a radiator problem. Before ordering a new radiator, carefully inspect these heater hoses, especially if the leak seems to be coming from the back of the engine bay.

Are there any differences between the 1993-1995 and 1996-2001 radiators?
Yes. The Dodge Grand Caravan had a major redesign in 1996. The radiators for the 2nd generation (1993-1995) and 3rd generation (1996-2001) are different and are not interchangeable. You must order the correct part for your specific year.
