GM ENGINE OIL DIPSTICK/FILL LOCATIONS

For Atoms with GM engines, the dipstick is located ju st forward of the right rear wheel.

38

HONDA ENGINE OIL FILL LOCATIONS
For Atoms with Honda engines, it may be necessary to unbolt the coolant reservoir to access the oil filler.

DIP STICK INDICATOR FOR HONDA ENGINES
Due to the Honda engine’s tilted positioning, the dip stick for the oil tank was modified. There are custom ized
holes drilled in the dip stick at 1/2 in. (12.7 mm) and at 1 in. (25.4 mm) for your point of reference.

ADDING & CHANGING ENGINE COOLANT


The engine coolant tank is located above the engine in the center of the engine compartment, under the air
intake cover.
WARNING: the system is pressurized at up to 15 PSI, and can cause severe burns! Only open the cap
when the engine is at ambient temperature and there is no pressure in the cooling hoses.


At the factory we use a vacuum device to pull the coolan t through the system, then a coolant pressurizing
system to apply 15 PSI to it. By the time this is done , there are virtually no air bubbles left in the system. You
will have to bleed the system very carefully using the following procedures:

1. Refer to the Fluid Levels & Types section on pages 35 & 36 for your engine’s specifications. Dilute coolant
50:50 coolant to water if the product comes un-diluted.
2. Carefully remove the 1/8 in. bronze pipe plug locate d at the top of the radiator. NOTE: if coolant rushes
out of this fitting, the engine may not need bleedin g.
3. Fill the coolant exchange tank over the engine unti l it will not hold any more coolant.
4. Start the engine and let it idle until the tempe rature at the thermostat housing reaches about 150 deg rees.
5. Check the radiator by touch to ensure it is warm. If it is not warm, turn engine off and let set. Restart.
6. Shut down the engine.
NOTE: The coolant temperature indicator on the SPA dash is no t reliable until the system is completely bled,
so do not depend on it for accurate readings yet.
