Cooling System
• Surface for seal
Remove any deposits that are found on these
items, and remove any material that is found on
these items.
3. Install the pressure cap onto a suitable
pressurizing pump.
4. Observe the exact pressure that opens the filler
cap.
5. Compare the pressure to the pressure rating that is
found on the top of the filler cap. The pressure cap
should open within 95 to 110 kPa
(13.7788 to 15.9544 psi). The pressure cap has a
nominal pressure rating of 100 kPa (14.504 psi).
6. If the filler cap is damaged, replace the filler cap.
Testing The Radiator And Cooling
System For Leaks
Use the following procedure to test the radiator and
the cooling system for leaks.
Personal injury can result from hot coolant, steam
and alkali.
At operating temperature, engine coolant is hot
and under pressure. The radiator and all lines to
heaters or the engine contain hot coolant or
steam. Any contact can cause severe burns.
Remove filler cap slowly to relieve pressure only
when engine is stopped and radiator cap is cool
enough to touch with your bare hand.
1. When the engine has cooled, loosen the filler cap
to the first stop. Allow the pressure to release from
the cooling system. Then remove the filler cap.
2. Make sure that the coolant covers the top of the
radiator core.
3. Put a suitable pressurizing Pump onto the radiator.
4. Use the pressurizing pump to increase the
pressure to an amount of 20 kPa (3 psi) more than
the operating pressure of the filler cap.
5. Check the radiator for leakage on the outside.
6. Check all connections and hoses of the cooling
system for leaks.
The radiator and the cooling system do not have
leakage if all of the following conditions exist:
• You do NOT observe any leakage after 5
minutes.
This document is printed from SPI². Not for RESALE
• The dial indicator remains constant beyond 5
minutes.
The inside of the cooling system has leakage only
if the following conditions exist:
• The reading on the gauge goes down.
• You do NOT observe any outside leakage.
Make any repairs, as required.

Engine Oil Cooler - Inspect

Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.

Typical example
Perform the following procedure in order to inspect
the engine oil cooler.
1. Place a container under the oil cooler in order to
collect any engine oil or coolant that drains from
the oil cooler.
2. Refer to Disassembly and Assembly, "Engine Oil
Cooler - Remove" for removal of the engine oil
cooler.
3. Thoroughly clean the oil cooler (1) and the cylinder
block.
