Chrysler Pacifica Radiator Coolant Hose Guide for 2017-2023 Models
Keep your Pacifica's engine from overheating by knowing when and how to replace a failing radiator hose.
- A leaking radiator hose is a critical failure; do not drive the vehicle to avoid catastrophic engine damage.
- Always use a 'molded' hose for your Pacifica, not a universal one, to ensure proper fit and coolant flow.
- If one hose fails from age, it is highly recommended to replace both the upper and lower hoses at the same time.
- Use the correct Mopar OAT coolant (purple) when refilling the system to prevent corrosion and damage.
Is Your Pacifica's Radiator Hose Failing?
Radiator hoses are wear-and-tear items. Made of rubber, they break down over time from heat, pressure, and exposure to engine oil. For a 2017-2023 Chrysler Pacifica, it's important to inspect these hoses during every oil change. Look for visible cracks, swelling, or soft, spongy spots. A failing hose is a serious issue that can leave you stranded.
Warning Signs of a Bad Radiator Hose
- Puddles of Coolant: Finding pink or reddish fluid under the front of your van is a classic sign of a coolant leak.
- Visible Hose Damage: Check for cracks, splits, or bulging on the hoses. They should feel firm, not mushy or rock-hard.
- Engine Overheating: If the temperature gauge on your dashboard climbs into the red, a coolant leak from a bad hose could be the cause.
- Sweet Smell: The smell of hot coolant is distinct. If you notice it after driving, you likely have a leak somewhere in the system.
Known Issues for 2017-2023 Chrysler Pacifica
While there are no specific recalls from the NHTSA for radiator hoses on the Pacifica, coolant leaks are a known issue. The most common causes of leaks are loose hose clamps, a cracked radiator, or a failing water pump. Sometimes, a leak from the engine's oil cooler housing can drip down and be mistaken for a hose leak. 🎬 See how a leaking oil cooler housing mimics a hose leak. Because of the plastic skid plates underneath, the spot where you see the drip on the ground may not be where the leak is actually coming from.

When shopping for a replacement, you'll see options from the original manufacturer (Mopar) and aftermarket brands like Gates.
- OEM (Mopar): These are the exact parts your Pacifica was built with. They guarantee a perfect fit but usually cost more.
- Aftermarket (Gates): High-quality aftermarket brands like Gates offer a reliable alternative at a better price. They design their parts to meet or exceed OEM specifications. The most important thing is to buy a molded hose specific to your Pacifica, not a generic "universal" hose. Molded hoses have the correct bends and shape for a perfect fit, preventing kinks that could block coolant flow.
Pro Tip: Replace in Pairs
If one radiator hose has failed due to age, the other one is likely not far behind. It's smart and cost-effective to replace the upper and lower radiator hoses at the same time. Also, consider replacing the spring clamps, as they can lose tension over time.

Frequently Asked Questions
Can I drive my Pacifica with a leaking radiator hose?
No. A small leak can turn into a complete hose failure without warning, causing a rapid loss of coolant. This will lead to severe engine overheating and can result in thousands of dollars in engine damage. It is not safe to drive.
Is replacing a radiator hose a DIY job?
For someone with intermediate mechanical skill, yes. The job requires safely draining the cooling system, reaching clamps in tight spaces, and properly refilling and bleeding air from the system afterward. 🎬 Watch this walkthrough on how to properly change your coolant. If you are not comfortable with this process, it's best to leave it to a professional mechanic.
What type of coolant does the 2017-2023 Chrysler Pacifica use?
The Chrysler Pacifica requires a specific OAT (Organic Acid Technology) coolant that meets Mopar specification MS-12106. It is typically purple in color. Using the wrong type of coolant can cause damage to the cooling system.
Will a bad radiator hose trigger the Check Engine Light?
A bad hose itself won't, but the problems it causes can. If the engine overheats or the coolant level gets too low, it can trigger codes like P0128 (Coolant Temperature Below Regulating Temperature) or P0217 (Engine Overtemperature Condition).
