P0217 on Dodge by model: symptoms, diagnosis and fix
The factory plastic-tank radiators on Challengers are prone to cracking and leaking, especially under spirited driving or in hot climates. The crimped plastic end tanks can fail at the seams. Many owners report needing radiator replacements between 60,000-100,000 miles.
Common Symptoms
- Coolant leak at radiator seams
- Overheating during spirited driving
- Low coolant warnings
- Green or orange puddles under front of car
- Steam from engine bay
How to Fix
Replace with an all-aluminum aftermarket radiator for long-term reliability. Mishimoto, Champion, and CSF offer direct-fit aluminum radiators with lifetime warranties. Also inspect radiator hoses and clamps during replacement. Consider adding a larger fan or oil cooler if tracking the car.

The mechanical (belt-driven) water pump on HEMI-powered Challengers is a recurring weak point that can fail well before normal service life, with owners reporting failures across a very wide mileage band — some as early as ~5,800-7,000 miles, clusters around 18,000-25,000 miles, and others out past 45,000-60,000 miles. The OEM Mopar pump uses a plastic impeller pressed onto a sealed bearing-and-shaft assembly. The dominant failure mode is bearing wear: as the bearing develops play and roughness, the shaft seal weeps coolant (a telltale trail of dried/crusty glycol residue on the pump body, distinct from harmless minor weep-hole staining), and in worse cases the loose impeller rubs the inside of the timing-cover/block bore, shearing plastic vanes off the impeller. Shed plastic circulates into the cooling system while the now-degraded impeller stops moving coolant effectively, producing localized overheating that can escalate to engine damage. This is a distinct component and failure set from the separately documented OEM radiator cooling issue — same system, different part. Dodge's own DodgeGarage how-to acknowledges the inspection points (loose/rough bearing and seal-deposit trail), and many owners and some dealers treat it as a known HEMI weak spot. A common, well-regarded fix is replacing the OEM plastic-impeller pump with a metal-impeller aftermarket unit (e.g., Gates) rather than another identical OEM pump.
Common Symptoms
- Coolant leak / drip at front of engine with dried crusty glycol residue trail on the water pump body
- Low coolant level and coolant smell after driving
- Growl, squeal, or frog-croak-like bearing noise from the front of the engine
- Play or roughness felt when rocking/spinning the water pump pulley
- Gradually rising coolant temperature gauge
- Engine overheating (when impeller fails and stops circulating coolant)
- Bits of shed plastic found in coolant / cooling system after impeller breaks up
- Often no check-engine light in early stages
How to Fix
Diagnose first: with the engine off, check the water-pump pulley/shaft for play (rock it) and spin for roughness/grinding; inspect the pump body for a dried, thick glycol deposit trail (sign of a failed shaft seal — replacement is required), as distinct from a harmless light stain at the weep hole. Listen for a growl, squeal, or "frog-croak" bearing noise from the front of the engine, and watch for slowly rising coolant temp or a coolant smell. The repair is replacement of the water pump (the pump is not serviceable). When replacing, many owners and shops recommend a metal-impeller aftermarket pump (e.g., Gates) instead of another OEM plastic-impeller Mopar unit to avoid a repeat failure. Replace the thermostat and any brittle gaskets/hoses at the same time, refill with the correct OAT coolant, and bleed the system. If the impeller shed plastic before replacement, flush the cooling system thoroughly and inspect the radiator/thermostat for debris. Torque the pump mounting bolts to ~18 ft-lb on HEMI applications (verify per year/engine). Caught early (seal weep / bearing noise, no overheating), it is a straightforward cooling repair; caught late (impeller failure + overheat), it risks downstream engine damage — hence prompt attention to bearing noise or coolant loss.

The Gen 1 and Gen 2 Vipers run hot in slow traffic on hot days. The factory single electric fan (roughly 2,020 CFM before the 1998 diameter increase) cannot move enough air through the radiator without ram-air, so coolant temps climb quickly in stop-and-go conditions above the low-to-mid 90s F, especially with the A/C on. Contributing factors include a weak high-speed fan relay, worn water-pump impeller (Gen 2), and leaking head/rear crossover gaskets, plus a factory temp gauge that is not always accurate.
Common Symptoms
- Coolant temp climbs in stop-and-go traffic
- Overheats with A/C on
- High temp on hot days, drops at speed
- Cooling fan not engaging (bad relay)
- Coolant loss from gasket leak
How to Fix
Verify actual coolant temp against the gauge, then address the specifics: replace/upgrade the radiator fan (the larger 1999-2002 fan is a popular swap) and rewire it for full voltage, replace the high-speed fan relay, verify the thermostat, and inspect the water-pump impeller and head/crossover gaskets for leaks. Higher-flow aftermarket radiators and dual-fan setups are common permanent cures.

Frequently asked questions
What does P0217 mean on a Dodge?
P0217 stands for "Engine Overtemperature Condition." This code sets when the engine control module detects that the engine has exceeded its safe operating temperature, meaning the engine is overheating based on the coolant temperature sensor reading. Because excessive heat can warp the cylinder head, blow the head gasket, or seize the engine, the computer flags this condition and may reduce power to protect the engine. It generally indicates a real cooling system problem rather than just a sensor glitch, though a faulty sensor can occasionally cause a false reading. An overheating engine should be stopped as soon as it is safe to avoid serious damage. On Dodge it is documented across 3 models: Challenger, Hornet, Viper.
What are the most common causes of P0217?
The most common causes of P0217 are: Low coolant level or a leak in the cooling system, Stuck-closed thermostat, Failed water pump, Faulty radiator cooling fan or fan circuit, Clogged or blocked radiator, Faulty coolant temperature sensor giving a false high reading, Head gasket failure or combustion gases in the coolant, Air pocket in the cooling system after service. The specific cause varies by vehicle.
How much does it cost to fix P0217 on a Dodge?
Published repair estimates on Dodge range from $200 to $1,800 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
