Stop the engine and check the coolant level in the reservoir. Start the engine and let it idle in place for three minutes. Push the coolant reservoir cap into place. 37 quarts of coolant or until the coolant is level with the "Full" mark imprinted on the reservoir. Fill the radiator with 1.37 quarts of the coolant mixture, then screw the radiator cap into place. Mix one quart of aluminum engine-safe ethylene glycol coolant with one quart of distilled water in a plastic container. Tighten the bolt to 7.2 foot-pounds by using a torque wrench. Allow the remaining coolant to drain into the drain pan, then screw the drain bolt into place. Remove the coolant drain bolt, located directly below the radiator hose, by using a 12 mm socket and a socket wrench. Remove the radiator cap, located at the bottom of the front fender grille opening.įollow the radiator hose to the left engine cover. Push the coolant hose onto the reservoir. Pull the coolant hose off the reservoir and allow the coolant to drain completely. Hold a drain pan below the coolant hose at the bottom of the reservoir. Remove the cap from the coolant reservoir, located along the ATV's frame under the left rear fender. Remove the grille panel from the front fender by using a 5 mm Allen wrench. I have to see where my oil pan is and how accessible it is to put a pad heater on it.Pull the release lever on the rear of the seat, then lift the seat off the ATV. I'm going to try the 5W and see how it goes. In the cold I have to horse it in and out a bit more while cranking. Usually full-on and it starts up when warm. Other things occur in the choke circuit but those are the basics.ĭouble check on what was done in the tune-up, just checks and adjustments or parts and adjustments. If it functioned properly in warmer temperatures and starts fine when warm (after running) this is where I would look.
Remove the air filter housing and filter, see if the choke valve is closed completely, crank the engine while holding the choke closed, let go once it fires, if it fires sooner the choke needs to be cleaned/set/adjusted.
Upon starting the choke valve opens slightly to allow for the proper air fuel ratio. If the choke is not fully closed and the throttle valve not opened slightly above idle, the venturi is not "shifted" to above the main metering circuit. When the choke is closed the fuel is delivered through both the idle and main metering circuit. The gasoline does not evaporate as well at lower temperatures. If the engine is not fuel injected, most probably the operation of the choke is at fault. Go to a synthetic, also synthetic in your air compressors really help them also. I am sure SteveC meant lower viscosity oil.
