III II Having car tunedup helps for easydriving winter Drivers grumbling about in creased fuel costs and cars that wont start on cold mornings this winter could have saved themselves the frustration with complete car tuneup Worn spark plugs and defec tive ignition systems are usual ly the cause for starting troubles and cause wear on the cars general performance Malfunctioning cooling systems burn excess gas and contaiminate the cars oil supp ly with sludge There are six steps to ensur ing smoother service and eliminating the cost and con sumption of keeping your car in heated garage check your batteries voltage regulator starter and generator distributor coils and spark plugs BATTERY Have your mechanic check your battery with hydrometer to determine its specific gravity and if the reading is low have the battery recharged and find out the reason for the low reading If the condition of the battery is in doubt have him check for weak cells Your mechanic should remove all corrosion from bat tery terrrunals and lubricate them to prevent corrosion from recurring Corroded cables and terminals restrict the flow of electricity through the entire system and can prevent cars from starting if lowed to go unattended VOLTAGE REGULATOR The re ulator should be proper ly justed An outof adjustment regulator may not allow the battery to charge enough or may result in over charging which could even tually ruin your battery STA GENERATOR If your car is less than two years old your only worry is seeing that any corrosion on either starter or generator connections be removed and that they are all securely fastened If your car is older have the generator brushes and com mutator checked Badlyworn brushes reduce the generator efficiency and can cause con stantly weak battery DISTRIBUTOR New points and condenser should be installed in engines that use them if your car has gone over 10000 miles since the distributor was last serviced Improperlyoperating distributions are major cause of starting problems OILS weak coil cannot only came starting failure but also contribute to general poor performance If your car has more than 20000 miles on the odometer your serviceman should check your coil condition SPARK PLUGSde If yoga are nearing to gills mark they should be replace before the weather um cold Wornout plugs are major factor in hard starting It is also good idea to have your mechanic check the engine with timing light Out oftime engines are hard to start and lose much of their ef ficiency cooling system tuneup is also good guard against needless energy consumption It involves thorough inspec tion and check of all parts of your cars cooling system and replacement of worn deteriorated or malfunctioning parts The cooling system tuneup is vital part of your cars maintenance allowing the engine to operate at proper temperatures and top efficien cy An engine that runs too cool will burn excess gas run rough and can contaminate your Oil with sludge buildup In turn an engine that heats Operating costs can be cut on furnaces in the home IWIceayezir servicing or your furnace can lll your heating bills by to per cent say officials of the federal llilliihll of energy mines and resources In ministry booklet on fur nace servicing they say an cffir cient system uses less oil or gas pollutes less and cuts operatingcosts The servicing would also mean an annual national sav ings of Son million if all taria diaiis reduced consumption by 10 per cent Most anadians heat their homes thh oil furnaces In conventional nilheating furnaces heating comes by mixing spray of oil droplets with air and igniting it to give flame To get the most heat your fuel should be burned completely and the oilair mixture should use the minimum amount of air that will give clean flame Smoke at the tip causes soot leOSllS There are three checks you can make to tell how well your furnace is working look for dirty flame check for soot and check the barometric damper To check the flairie look through flap which covers small hold at the front of your furnace Black smoke coming off the tip of the flame is sure Sign your burner needs adjustment To check for soot wait until the furnace is not operating take flashlight and look in All Btu Tube conttoo nozzle Typical OII Burner side the box The more soot you find the more inefficient your furnace and the more it is costing to heat your home lllSIIPINI If there is soot buddup ar range for an adjustment and cleiuiiiig There will be sortie soot burld up this Winter even With well functioning burner occuring when the burners sWitch on and the fuel oil hasnt yet mixed Will the air It also occurs when burner switches off lutch coupling or solenoid valve which you can price With your ser vtceman can counteract this The barometric damper is placed on the pipe leading from the furnace to the chimney With the valve bumping open and shut as the Wind blows and the furnace cuts in and out It alloWs cool air to be drawn from the basement into the chimney acting as buffer to keep most of the warm air in the furnace lieck the damper to be sure it sWings freely If it sticks clean and oil the hinges If it continues to stick it should be serviced Both furnace and burner should be checked and cleaned once in summer and once mid way through WllllCI SIX IIEfKS There are six important checks to be carried out on the twiceayear inspection by your serVIceman remove soot cleaning the firepot heat exchanger and pipes check the temperatures of gases leaving the furnace

fail To keep the engine at correct temperatures the cooling system sends ial coolant not water circu ating through the engine where it up heat being produced com bustion The cooling system in an average car engine must be able to withstand up to 20 pounds per square inch of pressure combined with underhood and coolant temperatures that can reach 275Fto300Ft135t0150C These high temperatures put pressures strain on all cooling system com nents coolant hosesdrive elts water pump thermostat and radiator cap One malfunction in any of these parts can result in overheating and costly internal engine damage 12 POINTS TO CHECK There is 12point checklist to follow in examining your cooling system avisiually check your system for leaks and check the coolant for the presence of Oil check the condition of your Vbelts checking belt tension with tension guage and readjusting if necessary pressurize system With cooling system analyzer to check for leaks and check pressure cap with tester test
