weather arrives, but install the heat | CT now, since it need not be put into | use until the nights get cold.
 Those wEo can afford it should by | all means fit some sort of winter | top to the open car, or if not that the inexpensive side curtain holders, so that the curtains will open with the doors. Enclose the car as best you can with the money you have to spend. The ideal is a permanent top with re- movable side windows; try to ap- proach that ideal.
 There are ever so many types or heater/ on the market to keep driver and passengers comfortable. There are electric heaters, heaters which use the exhaust gas and in another clasr all those using special fuels, which burn like wood or coal. The electric heaters are out os the question when economy is considered, because the average type uses entirely too much current. Also the initial cost of these heaters is greater than that of the others. The heaters using briquettes are simply the same ones which your grandfather used in his carriage. They are certainly efficient enough, but when the first cost and ease of opera tion and control of the exhaust, type
 
 any one would want any other type. The exhaust heater, of which there are dozens of designs on the market, is usually cheap in first cost, costs noth- Ing to operate and may be controlled so that any heat is maintained.
 1t may seem like a simple matter to install one of these heaters. but very often the driver finds that after the in stallation has been made the passen- gers are likely to be asphyxiated be- cause of the presence of exhaust gas in the compartment. In some cases the heaters are of cheap construction and allow some gas to escape. In other cases the heater is all right but the installation is poor. The car own CT will find many types on the market which may be placed in two general classes-the type in which the heater forms the footrest and that in which the hG ter is mounted on the floor either flush or above it. The Ques- tion of which design to take is not so important. Get a reliable make so you won't be bother with gas leakage On Shims
 The utmost care must be exercised to maintain an equal thickness of shims on each side of the bearing cap in refitting or readjusting. or the shaft will not bear on the same place on which it bore before readjustment. When the bolts are frightened the caps may be sprung and the shaft will be pinched. This will cause uneven wear on the bearings, which will soon | need further attention,
 Piston Pin Knock
 l The knock produced by loose pis- 1 ton pin is considerably lighter than a crank shaft knock and is most notice able when the engine is running idle with the throttle nearly closed. The only cure for the knock is to replace the pin or pushing or both, though | fortunately this knock does not indi- cate as dangerous a condition as a crank shaft or connecting rod knock. Missing Plug
 Tn cases where spark plug is miss ing because of it's sooted condition and no replacement is available the con dition may be overcome by discon- meeting the spark plug lead and in- stalling an auxiliary gap of an eighth or quarter of an inch between it and the plug terminal.
 Lubrieatins Trouble
 When a light gray smoke issues from the exhaust in winter it may be taken as an indication that the oil level is high and the fabrication con- sequently excessive. This may be due to the fact that water or gasoline has leaked into the case and become mixed with the oil. If pump fabrication is employed, water getting in here and settling to the bottom may freeze and cause the oil pump gears to shear off or some part of the pump driving system may be twisted off when the engine is turned over. Again water collecting in an oil pipe may freeze and stop the flow of oil to the. bear ings. At best the oil is thick in cold weather and flows to the parts /eedine it rather sluggishly until the engine IS thoroughly warmed up.
