here’s an exception to every rule.
ST255 and SVT262 radiator testing kits are great for testing the cooling
system on your vehicle—except when your vehicle happens to be a 2

-ton or
larger truck.
The tester head in the ST255 and SVT262 kits won’t fit on the radiator neck in
those trucks, so use adapter kit, NSN 4910-01-447-5586.
The kit comes with everything you need to test the radiators and radiator caps
of those big trucks. Order the kit on a DD Form 1348-6, adding “NSN not on
AMDF” in the REMARKS block.

tarting F5070 dump trucks in
cold weather has never been a snap,
but as the trucks get older, the chore
gets tougher.
You operators can make starting
these 20-ton monsters a little easier.
Here’s how:
Flip the glow plug switch to ON
and wait 20 seconds as the intake mani-
fold warms.

Have a buddy pull the compression
release lever at the front of the engine
to allow the engine to turn over easier.
Pump the fuel pressure primary
pump until you get 80–100 psi.
Crank the engine. When it’s turning
over, have your buddy let go of the
compression lever.
After the engine starts, pump the
primer slowly for a few minutes until
the engine warms up and runs
smoothly.
Then push the primer handle in and
lock it. Turn the glow plug off so it’ll
be ready for the next time.
Never
use ether to help start the
F5070. Mix ether with a glow plug
and you can cause a fire or an
explosion.
If the engine doesn’t start after 20
seconds, stop cranking and stop
pumping the primer. Let the starter
cool for two minutes.
Make sure the glow plug is work-
