Engine Coolant Temperature Gage

This gage shows the engine coolant temperature.

It also provides an indicator of how hard the vehicle is

working. During a majority of the operation, the gage

reads 210° F (100° C) or less. If a load is being pulled

or going up hills, it is normal for the temperature to

ﬂuctuate and go over the 235° F (113° C) mark.

However, if the gage reaches the 260° F (125° C) mark,

it indicates that the cooling system is working beyond

its capacity.

Oil Pressure Gage

The oil pressure gage shows the engine oil pressure

in psi (pounds per square inch) when the engine

is running. Canadian vehicles indicate pressure in

kPa (kilopascals).

Oil pressure should be 29 to 80 psi (200 to 550 kPa).

In certain situations, such as long extended idles on

hot days, it could read as low as 15 psi (105 kPa) and

still be considered normal.
