Keep It Going - Weekly Checks (continued)
Wednesday, January 31st, 2007Moving around the engine bay to the engine coolant level, checks here will depend on the particular cooling system layout and in most cases will comprise the radiator, which may or may not have a filler cap, and a heater tank which will have both a filler cap and some method of indicating the correct level. Firstly, and of vital importance, never ever release the filler cap when the engine is hot, removing this cap may well result in the escape of steam and/or coolant at high temperature. This mixture will be sufficient to cause serious scalding to any area of skin it comes into contact with. Suffice to say that coolant level is best checked without touching the filler cap via the “see through” header tank, if this is not possible wait at least ½ hour before slowly releasing the cap, ideally when wearing a substantial glove or a quantity of rag placed over the filler cap. The level check is simple enough but what is not quite so obvious is the strength of the antifreeze/water solution which provides not only protection against the system freezing but also a high degree of corrosion protection for the cooling channels within the engine. Again, a simple device can be purchased from most motor accessory shops for a few pounds which will give a reasonable indication of coolant strength. In most cases 50/50 mix of antifreeze/water should be used for topping up and this is best done with a pre-mixed solution and not via the method of adding neat antifreeze and then adding water as this can give rise to pockets in the header tank/radiator area that have a lower level of protection.
Now to the easiest check of all, the windscreen washers/wipers. Simply add a quantity of screenwash additive to the reservoir and then fill with water and the job is done. There is however little point in topping up the reservoir if the washer jets are blocked or mis-aligned and we have all seen cars whose washer jets are aimed better at the vehicle behind rather than the one they are attached to! For the regular four jet system aim two of the jets to hit the screen approximately 1/3 of the way up and the other two 2/3 of the way up, this will give good washer performance at all speeds. Moving the jets is usually done with a fairly robust needle and to clear them of the usual build up of wax and road grime a short length of wire carefully prodded into the jet whilst the washers are operated normally brings them back to life. Washers, of course, are of little use without an effective wiper system and here all we need do is ensure that the blades are not split, not juddering or smearing on the screen. If any of these conditions are apparent change the whole blade, replacing the rubber insert is a false economy and a fiddly job to boot! From first hand experience I recall failing a car during an MOT test for having split wiper blades, seeing this owner wrestling for ages with various tools and a pack of wiper inserts then submitting the car for re-test only to find that the inserts are doing a worse job in clearing the screen than the originals! Do yourself a favour and swap the whole unit it may cost a little more but takes much less time and is easier on your nerves.
Judging by the number of cars on the road with one or more lights not working makes me think that drivers rely on the annual MOT test for a lights check. It can take less than five minutes for a complete lights check with the aid of an assistant, so there is no excuse for this check not to be done on a weekly basis and if you find any lights to be out they can be cheaply replaced particularly for Vauxhall owners as used Vauxhall headlamps N/S or O/S can be bought for next to nothing and work just as well as new ones. Moreover, it is so easy for some lights to be checked whilst sat in traffic looking out for reflections in shop windows and the vehicles in front and behind. Obviously from a legal point of view lights need to be effective as well as working, headlights and rear lights can be rendered next to useless when covered by a thick layer of road grime and again it takes only a few minutes with a cloth and some water to make things clear. Lastly, and an item that causes some annoyance, is the subject of headlamp aim, under normal operating circumstances, i.e. not towing a laden trailer or caravan, the headlamp height control, where fitted, should be set at zero. I have come across many people that think this control is for brightness and move it to the highest number, all they are doing is lowering the headlamp aim, effectively reducing the useful light available for driving. The other aspect of aim is of course that of being too high, this usually causes drivers of oncoming vehicles to be dazzled and flash their main beam in retaliation. Should this occur get the headlamp aim checked at an MOT testing station and adjusted where necessary.
The final section of this article is on the subject of fuel, and all that is required is to check the gauge before setting out and ask yourself the question, "do I have enough fuel to get to a filling station before/after work/shopping etc" and "do I have enough money once I get to the filling station". It is never a good idea to regularly run the fuel level so low that the warning light comes on or the gauge shows empty, doing this increases the chance of the fuel pump drawing up some of the contaminants laying around in the bottom of the tank, it is far better to run the level to around quarter full or some other convenient marker on the gauge.
Please bear in mind that the weekly checks are done to help keep your vehicle in something like a safe and roadworthy condition showing up obvious faults in their earliest stages before they create a breakdown situation, thus causing hassle and expense. Remember Vauxhall car parts and parts for other makes can be much cheaper to purchase than new car parts.
When driving sometimes you think your invinsible and we do silly things which put us at risk and we dont even acknoledge the fact that it could be our last drive. You maybe thinking what is he on about so let me clarify. Have you ever took your eyes off the road to alter car parts such as tune a radio station, change your ipod, pick up the lolly pop you dropped etc.
I currently travel on a morning down the a19 from Durham to the offices near Middlesbrough. I would consider this road a dangerous road, there is always a turned over lorry, a 3 car pile up etc at least once a week and this is in the summer.
