Pressure’s on to get it right
Q: We have had to put new tyres on our Ford Territory after four years. The tyres show they should be inflated to 40 psi, but the car’s manual says 32 psi for regular unloaded driving for a Territory. Should I follow the tyre or the car guide? KC, email. A: Follow the placard on the car. The pressure shown on the tyre sidewall is the maximum inflation pressure it can withstand — it has got nothing to do with the pressure you should run on your car.
Q: I recently had an external transmission cooler fitted to my non-turbo automatic BA Falcon ute and I reckon the power has increased by about 10 per cent. Could this be true or is it just wishful thinking? The mechanic who fitted it could not confirm or deny it without doing a dyno test, which I amnot keen to do. Geoffrey Collits, email. A: There’s no reason to believe adding a cooler would increase the performance. I wouldn’t bother wasting your money on a test.
Q: The Ford Falcon 2008 series
Rough running and backfiring are common issues with LPG cars, particularly those running the old technology
III straight gas wagon I recently bought has been idling rough when stopped at the lights when in ‘‘drive’’. My Ford dealer said the air intake was cracked and replaced it, but it still ran roughly and began to backfire when starting. I took it back a second time and they said it was the inlet manifold gasket and battery, and changed both, but it wasn’t fixed. I cannot afford to lose my car for another whole day because I need it for work six days a week. Any ideas? Craig. A: Rough running and backfiring are common issues with LPG cars, particularly those running the old technology as your old Falcon is running. It’s usually a problem with the ignition system, such as spark plugs or spark plug leads. I would replace them.
Q: I began experiencing a vibration through the steering wheel of my 2010 Ford Fiesta Zetec soon after buying it. My Ford dealer advised me that all four wheels were buckled and that as a result my car was unroadworthy and that all four wheels needed to be replaced. They also advised me to replace the tyres. I was advised that the sporty-type of car and the alloy wheels make it susceptible to non-freeway roads.
