peRKiNS recommends antifreeze/summer coolant for use in
their engines, which can be purchased in concentrate (and
mixed with 50% demineralized water) or pre-diluted. See the
peRKiNS engine Owner’s Manual for further details.
Day-to-day addition of coolant is done via the radiator.
When adding coolant to the radiator, DO NOT remove the
radiator cap until the unit has completely cooled. Coolant
capacity is 4.5 gallons (17 liters).
Operation in Freezing Weather
When operating in freezing weather, be certain the proper
amount of antifreeze Table 7 has been added.

If adding coolant/antifreeze mix to the
radiator, DO NOT remove the radiator cap
until the unit has completely cooled. The
possibility of hot! coolant exists which can
cause severe burns.

Radiator Maintenance
1. Check radiator for leaks that would indicate corrosion
or damage.
2. Check coolant level daily. Top off as necessary. Always
use recommended coolant/antifreeze. Use the mixing
ratios specified by the coolant/antifreeze manufacturer
or (Table 7). Replace coolant/antifreeze at least once
a year.
3. Check radiator hoses for fatigue or cracking. Replace
any defective hoses immediately.
4. Check radiator cap seal and replace as necessary.
5. Blow off dirt and dust from fins and radiator with 28
psi (193 kPa) or less of compressed air (Table 7). Be
careful not to damage the fins with the compressed air.

6. If there is a large amount of contamination on the fins,
use detergent to clean and rinse thoroughly with tap
water.
