AVOIDING TRAILER WOES

Many drivers refuse to tow trailers and in truth, they can be accidents no longer waiting for a place to happen. However, many potential problems can be avoided by regular inspection and maintenance. Here are some suggestions:

1. Left side wheel nuts. Think about it – right hand threads on the RIGHT SIDE of the trailer will try to tighten themselves as the wheel rotates. BUT the right hand threads on the LEFT SIDE wheel nuts are trying to undo themselves. Check them for tightness BEFORE setting out to avoid losing the wheel when the nuts spin off. Don’t laugh – this happens frequently

2. Don’t expect the ball of the coupling to stay tight – vibration may cause the nut to loosen even if fitted with a spring washer, resulting in it literally falling off the tongue. Remove the ball joint, drill a 4 mm hole right through the shaft below where the nut will sit when tight. Replace it and insert a heavy split pin through the hole you drilled.

3. Though hard to believe, the spring pin securing the towbar tongue to the frame has been know to fall out, Then it is only a matter of time before the entire tongue works its way out of the frame. Because the safety chain is usually shackled to the tongue and not the actual vehicle, the trailer will fall off along with the tongue. On a highway this could result in serious accident to a following vehicle. The solution is to replace the spring pin with a bolt and nylock nut OR replace the entire pin with a 1/2″ high tensile bolt and nylock nut. Do NOT use plain nuts or they will work loose too.

4 Driving techniques should be practiced BEFORE setting out onto the public roads. This especially means learning how to back and turn safely without hitting another vehicle OR jack-knifing the trailer into your vehicle. If rear vision is poor, screw or bond a length of brightly coloured metal or plastic so these sit proud of the extreme front edges of the trailer and can be seen easily in your side mirrors

Finally, check your wiring before setting out. It is easier to repair a broken wire at home than do it on the roadside – especially if the Fuzz have stopped you for not having working lights

LAND ROVER traction control

Love to know which idiot at LR or their ad agency decided to post this picture as the example of traction control on a new Disco.

Did they not notice the cable attaching the vehicle to the dozer (or whatever) parked at the top of the hill?

This is either misleading advertising or someone’s idea of a bad joke. Don’t think it will do much to improve sales

AUTO AIR CONDITIONING REPAIRS

The time will come, regardless of the age of the vehicle that the air-conditioning is no longer as cold as you would like it – or as cold as it used to be. To fix this, you may be looking at any cost between a few hundred dollars to many thousands. This is where some background knowledge and good advice can save a great deal of money as well as get the result you want.

The first consideration is the electrics, meaning does the compressor turn on when the controls are switched on? Is air coming from the vents, even if it is not as cold as you want?  You should be able to hear the clutch of the compressor engage and feel air at the vents. Assuming you can, this will not be the cause of the problem.

Far more likely is a leak, or more than one leak in a hose or a seal. They operate under high pressure and heat so deterioration over time is inevitable. A repairer will put dye into the system and under UV light will determine where the leak occurs. If a compressor seal is defective, it can be repaired but it may be far less costly to obtain a good used replacement from a compatible wreck. “Compatible” is the key here because not all compressors will suit your vehicle. However, perhaps the end section can be taken from yours and fitted to the replacement , overcoming the greater cost of pulling yours apart, replacing seals and probably bearings too. Contact Craig at Graeme Cooper Automotive – he may have or can get a good used unit.

A new dryer is essential. Also, it will not be worth attempting to repair defective hoses. Although new ones and fittings custom made to suit your vehicle are fairly expensive, it is the only way to repair a system effectively. A decision will have to be made whether to replace ALL hoses including the ones under the dashboard or just those within the engine bay (the ones copping the heat from the engine). Removing the dash will add several hours of labour and it is possible the leaks may be in the easier -to-access sections. It will be a judgement call.

Graeme Cooper Automotive are experts in diagnosis and repair and can save many hours of frustration and probably cost too.

Craig to the rescue!

Craig Flood is the Parts Manager at Graeme Cooper Automotive. Some say he can jump over small buildings without a run up. Certainly he is one of the most helpful parts specialists I have ever met

One recent example was a Range Rover broken down in the northern Territory and nowhere in the area was there a supplier with the bits needed to get it going. One call to Craig and all was resolved with delivery to the owner within 48 hours

Now that is service!.
