Dodge Grand Caravan Radiator Replacement Guide (1987-1992)
Running hot in your first-generation Grand Caravan? This guide covers everything you need to know about choosing and replacing your radiator.
- For a 1987-1992 Grand Caravan, a new aftermarket radiator is the best and most available option.
- Overheating is the number one sign of failure; pull over immediately to prevent engine damage.
- Always replace the radiator cap and thermostat at the same time as the radiator for best results.
- If you have an automatic transmission, ensure your replacement radiator has the correct transmission cooler fittings.
Is Your Grand Caravan's Radiator Failing?
For a vehicle from this era, the radiator has worked hard for decades. Failures are common due to age, internal corrosion, or physical damage. The most common reasons for overheating in a 1987-1992 Dodge Grand Caravan are coolant leaks, a bad radiator fan, or a failed thermostat. A faulty radiator is a primary source of these leaks and overheating issues.
Symptoms of a Bad Radiator:
- Engine Overheating: The most obvious sign. If your temperature gauge is climbing into the red, your cooling system isn't working correctly.
- Coolant Leaks: You might see puddles of green or orange fluid under the front of your van. Leaks often happen at the seams where the plastic end tanks are crimped to the metal core.
- Visible Corrosion or Damage: Look for rust-colored stains, bent cooling fins, or white, crusty deposits on the radiator itself. These are signs of leaks and reduced efficiency.
- Low Coolant Level: If you constantly have to add coolant to the reservoir, you likely have a leak somewhere in the system.
- Sweet Smell: The smell of antifreeze when the engine is warm is a sure sign of a coolant leak.
Can I still drive with a bad radiator?
It is not recommended. Driving with a faulty radiator risks severe engine damage from overheating, including warped cylinder heads or a blown head gasket, which can be catastrophic for the engine. If you see steam or the temperature gauge is in the red, pull over immediately and shut off the engine to prevent further damage.
Choosing a New Aftermarket Radiator
For a classic vehicle like the 1987-1992 Grand Caravan, finding a new Original Equipment Manufacturer (OEM) radiator from Mopar is highly unlikely. Aftermarket radiators are the most practical and affordable solution. Modern aftermarket radiators are designed to meet or exceed original specifications and are a reliable choice for daily driving.
Available Brands:
When shopping, you'll encounter several brands. Many are made in a few large factories and re-boxed, but some have a more established reputation.
- Spectra: A widely recognized brand in the aftermarket. They produce a huge range of cooling products. Reviews are generally positive regarding price and performance, though some users report minor fitment issues requiring small modifications.
- APDI: Often seen as a budget-friendly option. Reviews are mixed, with some users reporting issues with quality and incorrect fittings. For a critical part like a radiator, it may be worth spending a bit more for a brand with a more consistent track record.
- Global Parts / One Stop Solutions: These are often private-label brands. They can be a good value, but quality can vary. They are typically designed as direct-fit replacements and are a viable option if on a tight budget.
Pro Tip: Replace More Than Just the Radiator
While you have the cooling system drained and accessible, it's smart and cost-effective to replace a few other key components. Always install a new radiator cap, thermostat, and consider replacing the upper and lower radiator hoses if they feel soft, swollen, or brittle. This preventative maintenance can save you from another cooling system failure down the road.

Frequently Asked Questions
Can I replace the radiator myself?
Yes, for a mechanically inclined person, this is a very feasible DIY job. The process involves draining the coolant, disconnecting hoses and transmission cooler lines, unbolting the fan assembly and radiator mounts, and swapping the part. It typically takes 2-4 hours. Be sure to have a good set of tools, a drain pan, and to follow safety precautions.
What kind of coolant should I use in my 1987-1992 Grand Caravan?
For this generation of vehicle, a traditional green or yellow IAT (Inorganic Additive Technology) coolant is appropriate. Always check your owner's manual or a reliable service guide. When you refill, mix the concentrated coolant with distilled water to a 50/50 ratio to prevent mineral buildup.
Do I need a radiator with a transmission cooler?
Yes, if your Grand Caravan has an automatic transmission. The radiator has an integrated but separate chamber that cools the transmission fluid. Your new radiator must have the correct fittings for the transmission cooler lines. Be sure to verify this when ordering.
Are there any recalls for the radiator on this van?
No, there are no specific recalls issued by the NHTSA for the radiator on the 1987-1992 Dodge Grand Caravan. Any cooling system issues are typically due to the age and wear of the components.
