When To Replace The Timing Belt On A 2007 Alfa Romeo 147 (1.9 JTD M-Jet 16V)

When it comes to servicing and maintenance on your Alfa Romeo, one of the most important considerations is timing belt replacement (aka ‘cam belt’)

Failure to replace the timing belt within the required interval – either distance or time – could result in catastrophic engine damage, and potentially a one-way trip to the scrap heap for your car.

On this page you’ll find convenient, accurate information on timing belt replacement for your 2007 Alfa Romeo 147 with the 1.9 JTD M-Jet 16V engine.

Official, Initially-Stated Timing Belt Intervals

When your car first released, the following was the recommended timing belt replacement information:

Timing Belt Replacement Interval (KM)116,000km
Timing Belt Replacement Interval (Miles)72,000mi
Timing Belt Replacement Time5 Years
Warning: Do NOT rely on this timing belt information that was provided at launch for your car.

However, over time it came to the attention of Alfa Romeo that timing belts were failing prematurely on the 2007 1.9 JTD M-Jet 16V engine, resulting in catastrophic engine failure and costs for owners and Alfa Romeo alike.

Therefore, timing belt intervals were changed to the following. You should not use the original interval, and instead rely on the following. If you are looking at buying a 2007 147 with the 1.9 JTD M-Jet 16V engine and it has been maintained using the original interval recommendations (listed above) you may need to factor in organising a new timing belt/cambelt sooner than expected – work this in to your price neogtiations!

Recommended Timing Belt Intervals

The new timing belt interval for the 2007 147 with the 1.9 JTD M-Jet 16V engine is as follows:

Timing Belt Replacement Interval (KM)77,000km
Timing Belt Replacement Interval (Miles)48,000mi
Timing Belt Replacement Time4 years recommended, 5 maximum

Don’t risk expensive engine damage that might result in your Alfa Romeo becoming a write off – change the timing belt/cambelt as per the recommended interval/time. If you have no evidence of a previous change, get this job done ASAP.

Timing Belt Replacement For 2007 147 With 1.9 JTD M-Jet 16V Engine – Notes

Here are some other considerations:

  • While replacing the timing belt, it’s often recommended to also replace the water pump, tensioners, and idler pulleys as these parts often have a similar lifespan to the timing belt. If they fail, they can cause significant damage to your engine. Instead of purchasing these components separately, consider a timing belt kit. These kits often include the timing belt, tensioner, idler pulley, and sometimes the water pump.
  • The water pump is often driven by the timing belt in many Alfa Romeo models. If the water pump seizes, it can break the timing belt, causing significant engine damage.
  • Replacing the timing belt on a 2007 147 (1.9 JTD M-Jet 16V) is a complicated task that often requires special tools and expertise. Unless you’re an experienced DIY mechanic, it might be best to have this job done by a professional.
  • Keep a record of when you replaced the timing belt, including the date and mileage. This information will be useful for planning future maintenance and for potential buyers if you decide to sell your car.
  • The timing belt synchronizes the rotation of the crankshaft and the camshaft(s) so that the engine’s valves open and close at the correct times. If the timing belt fails, it can cause the engine to stop running or, in worse cases, cause severe engine damage due to piston to valve contact. Although Alfa Romeo timing belt replacement is typically costly compared to other makes and models, the cost of NOT replacing your timing belt on your 2007 Alfa Romeo 147 with the 1.9 JTD M-Jet 16V engine could be significantly higher if failure occurs.
