Is Your Water Pump Failing? Common Symptoms
A water pump on a 1978-1982 Chrysler Town & Country is a straightforward mechanical part, but when it starts to fail, it gives clear warnings. Ignoring them can lead to major engine damage from overheating.
| Symptom | What to Look For |
|---|---|
| Coolant Leaks | This is the most common sign. You may see drips of green or orange coolant on the ground under the front of the engine. Look for a white or colored crusty trail leaking from the small “weep hole” on the bottom of the pump. This hole is designed to leak when the internal seals fail. |
| Engine Overheating | If the temperature gauge on your dash climbs into the red, the water pump's impeller may have corroded or broken, preventing it from circulating coolant effectively. |
| Grinding or Squealing Noises | A high-pitched squeal or a low-pitched grinding noise from the front of the engine that changes with RPM can signal a bad water pump bearing. The bearing supports the shaft, and when it wears out, it can cause the pulley to wobble. |
| Wobbly Pulley | With the engine off, try to wiggle the fan attached to the water pump pulley. If you feel significant play or wobble, the pump's bearing is shot and the entire unit needs to be replaced. | 🎬 Watch: How to diagnose a bad water pump
Choosing the Right Aftermarket Water Pump
For a vehicle from this era, new factory (OEM) parts are no longer produced. The market consists entirely of new aftermarket parts. Quality can vary, so choosing a reputable brand is important for a part this critical.

A Note on Engine Fitment

Pro Tip: Replace More Than Just the Pump

Frequently Asked Questions
Can I still buy an original Chrysler water pump?
No, new OEM water pumps for this vehicle have not been manufactured for decades. Any “OEM” parts found would be New Old Stock (NOS), which are extremely rare, expensive, and may have degraded seals from age. A quality new aftermarket part is the most practical and reliable option.
Is it hard to replace the water pump myself?
For a mechanically inclined person with the right tools, this is a very feasible DIY job. The engine layout provides good access to the front-mounted pump. The process involves draining the coolant, removing belts, unbolting the fan and pulley, and then unbolting the pump itself. The biggest challenge can be cleaning the old gasket material off the engine block 🎬 Watch: Step-by-step 318 V8 water pump replacement for a clean seal.
What kind of coolant should I use?
For these older engines, a conventional green or universal gold ethylene glycol-based coolant is appropriate. Using the wrong type of coolant can cause corrosion and lead to premature failure of the new water pump. Always use distilled water to mix with concentrated coolant, never tap water.
Should I get a high-flow water pump?
For a stock engine in normal use, a standard replacement pump is perfectly adequate. A high-flow pump from a brand like Edelbrock or PRW might be beneficial if you have a modified engine, live in a very hot climate, or use your vehicle for towing, as it can improve cooling at low engine speeds.
