Why did my Dodge Aries lose power and now cranks with no spark?

Short answer: When an Aries loses power and then cranks with no spark, check the timing belt first: pop the distributor cap and watch the rotor while someone cranks. If the rotor doesn't turn, the belt broke. Clicking without cranking means battery or starter.

Symptom: The engine lost power while driving and now cranks but won't fire, or it pours coolant.

What to check first

1. Remove the distributor cap and watch the rotor while someone cranks.
2. If the rotor turns, check for spark at a plug.
3. If you only hear a click, test the battery and starter connections.
4. For a coolant leak, find exactly where it comes out and check the radiator fittings.

Likely causes

1. Broken timing belt. The timing belt turns the camshaft and distributor. If it breaks, the engine cranks but there's no spark and no running. On this engine, owners said a break usually doesn't damage the valves.
2. Ignition pickup or module. These parts trigger the spark. If they fail, the engine cranks with no spark.
3. Weak battery or starter. A clicking sound instead of cranking usually means a weak battery, bad cable or tired starter.
4. Radiator leak. Old radiators crack or lose fittings and pour coolant.

What it usually costs

Owners didn't post prices. A timing belt is a moderate shop job; a radiator repair or replacement varies, so get a quote.

Is it safe to keep driving?

Losing power while driving is dangerous. Don't drive with a coolant leak, the engine can overheat.

DIY or shop?

The rotor test and battery checks are DIY. Timing belt replacement suits an experienced DIYer.

Recalls, bulletins and complaints in plain words

• Related recalls: NHTSA lists 13 recalls for the Aries in these years. Related ones: 84V147000 (1984-1985, fuel could leak at the seam and hose connections of the silver fuel reservoir can mounted on the air cleaner) and 89V237000 (1989, the valve cover gasket can slip out of place and leak oil). None is about the timing belt or radiator. Check your VIN at nhtsa.gov/recalls. If your car is part of a recall, the dealer fixes it for free.
• Plain words: NHTSA's online data for these years is limited, so owner experience carries the most weight.
• NHTSA complaints: 3 keyword-matched complaints for Dodge Aries 1981–1989 (of 43 unique complaints queried, NHTSA complaints API by model year, queried 2026-10-28; keywords: start, crank, overheat, radiator, coolant, timing). This counts complaints that mention these words. It is not a defect finding.

What owners report

• In 87 Dodge Aries Freespinning WILL NOT start on Car Talk, a 1987 Aries lost power and then cranked with no spark. Members said to check the timing belt by removing the distributor cap and watching whether the rotor turns while cranking, said a clicking sound points to the battery or starter, and said this engine is not an interference design.
• In Radiator Help for K Car on Car Talk, a 1986 Plymouth Reliant, the Aries' twin, poured coolant from an unused radiator port. Members suggested JB Weld as a temporary patch and a radiator shop for the real fix.

Quick tip

Watching the rotor is a 30-second test that tells you whether to buy a timing belt or keep looking.

Vehicle focus: Dodge Aries (and Plymouth Reliant twin), 1981-1989.
