t
he hot and humid days of summer
means it’s time to remove the
HEMTT’s ether cartridge.
Summer weather causes the cartridge
to rust and leak. Then the vehicle’s
ether start won’t kick in when you need
it for those winter months down the
road.
So do your HEMTT a favor. Remove
the cartridge in the summer or in places
where it’s warm all year around. The
cartridge is there only to help the truck
start in cold temps.
Just unscrew the cartridge from the
solenoid valve and plug the hole with
the cap that is chained to the solenoid.
Be sure to store the ether cartridge in
a cool, dry place so it can be put back
on when you need it—in cold weather.

hey!
wait!
I need
more
coolant!
Fill
'er up!
W
hen filling a new HEMTT radiator, don’t be fooled into thinking it’s full when
it’s not, mechanics.
There’s a lip just inside the
radiator opening that can hold
some fluid and make it appear
to be full when it’s not. What’s
worse, the heat sensors are
located near the top of the
radiator, so they don’t get
tripped by the overheated fluid
in a partially-full tank.
The end result is an over-
heated engine. So keep putting
coolant into the radiator until
it reaches the bottom of the
filler neck.
