Example: Alto Overheats on the Lowari Tunnel Approach
Illustrative example based on typical jobs. It doesn't describe a specific customer.
- Where
- Approach road to the Lowari Tunnel, Upper Dir side
- Vehicle
- Suzuki Alto (hatchback, petrol)
- Service
- Emergency Mechanic
The situation
In a typical job like this, a family drives a fully loaded Alto towards Chitral. On the steep climb before the tunnel the temperature warning comes on and the engine starts to lose power.
How a job like this is handled
Pull over and cool down
The driver stops well off the road with hazards on and the bonnet up. The crew advises against driving into the tunnel with an overheating engine.
Find the cause
Once the engine is cool, the mechanic checks coolant level, hoses, the radiator fan and the water pump for leaks or failure.
Fix what can be fixed
A split hose, loose clamp or blown fan fuse can often be repaired at the roadside, followed by a coolant top-up and a test run.
Long tow if needed
If the head gasket or pump has failed, the car goes on a flatbed for a long-distance tow to a workshop in Dir, Chitral or further, as the family decides.
The outcome
In a job like this the family either continues with a repaired cooling system or travels on with the car loaded safely on a flatbed.
What drivers can learn
- Do not overload a small car for mountain trips; weight makes the engine work harder on climbs.
- Check coolant and hoses before driving north.
- Stop at the first sign of overheating rather than pushing on to the top.
- Never enter a long tunnel with a car that may stall.
