Travelling by car has several advantages over the bus. There are certain basic things you must check in your car before the trip. Replace the fan and AC belts and keep the old ones as spare. If the vehicle has clocked around 80,000 kms replace the timing belt. Make sure that the timing belt is an original one and have it replaced by a professional mechanic who has the tools available to do the job. Replace the spark plugs if they are old. Also, make sure all tires including the spare wheel are in good condition. Fill up your tank at the first petrol station once it reaches the half tank level.
