prohibit their use. Local laws should be
checked for possible legal limitations.
Where it is necessary or desirable not to
use the warning light, the wir e can simply be
disconnected and the ends of the wires insu-
lated by taping, etc., or the flasher unit can
be removed. The flasher unit is located in-
side of the combination wo rk-tail light.
Where it is necessary, or desirable not
to use the flashing wa rning light, but to use
the warning lights as a steady burning light,
the flasher unit may be shorted across by
securely wrapping the flasher prongs with
several wraps of copper wire, or by solder-
ing a wire onto both prongs and plugging the
flasher unit back into the clip. The two
wires in the flasher plug-in clip could have
the insulation removed in a small area, the
wires twisted or soldered together and then
insulated by taping, etc. , or a jumper clip
could be cut out of copper or aluminum and
plugged in place on the flasher unit.

Cooling System
The cooling system on the MF 135 Trac-
tor consists of a radiator, pressure-type
radiator cap, fan, thermostat and water
pump. The cooling system capacity is 10. 5
U.S. - 8. 4 Imp. quarts. The cooling system
in both the gas and diesel engines incorpo-
rates a thermostat by-pass port, which al-
lows a more rapid and even engine warm-up.
This type of system circulates a metered
amount of the coolant through the water pump
back into the engine block before the thermo-
stat opens.
Care of the Cooling System
.£ It is important that dirt, chaff, etc.,
be kept cleaned from the radiator fins. To
simplify cleaning the radiator fins, the
Tractor grille is easily removed to gain ac-
cess to the radiator. To remove grille,
loosen the knurled knob at the top of the
grille, tilt top of grille out and lift it up.
(See Fig. 69.)
The radiator is completely sealed at the
edges so that all air must pass through the
grille. The air holes in the grille are
smaller than those in the radiator. If any
foreign material passes through the grille,
it should pass through the cooling fins in the
radiator, preventing the fins from becoming
plugged. This also helps to keep the fins of
the radiator cleaned and prevents once cir-
culated air from recirculating through the
radiator.
