When vehicle is cool remove the radiator cap and bring it to your local auto parts store. Most stores can test it for you. It should hold pressure up to number on cap. That varies from vehicle to vehicle anywhere from 7# to 16#.
the vent in your fuel tank is not working properly
It may not be blowing out pressure. But it is actually sucking in Air. The fuel tank has to be sealed and hold a vacuum for emissions. Because it sucks air in means it is working properly
To pressure test a radiator cap, you will need a radiator pressure tester kit. Remove the radiator cap, attach the pressure tester to the radiator neck, and pump it up to the specified pressure level. Observe for any leaks or pressure loss to determine if the radiator cap is functioning properly.
it will pobablyuse a 13lbs. cap but when you go to the parts store they will tell you
The spring on the bottom of a radiator cap will cause it to fail. If the spring does not work properly it can lead to pressure escaping from the radiator which can overheat the vehicle.
To properly pump bike tires, first check the recommended tire pressure listed on the sidewall of the tire. Use a bike pump with a pressure gauge to inflate the tire to the recommended pressure. Remove the valve cap, attach the pump nozzle to the valve, and pump air into the tire until it reaches the desired pressure. Be sure to replace the valve cap when finished.
Do you have fuel ?Check fuel pump pressure with a gauge. You should be able to remove the gas cap and put your ear to it and hear the fuel pump run when someone turns the key on. That will tell you if the pump is working are not. Pressure test will tell you if the pump is up to power.
There should be some pressure. Check/replace Radiator cap. The cap will tell you what the pressure of the cap is before it opens and vents to the overflow. Be sure Thermostat is not in Backwards. spring side should be towards engine. Engine will over heat if it is in backwards.
Evaporative Emission Control System MalfunctionCausesThe gas cap is not installed or working properlyThe purge solenoid has failedThe canister is plugged and not working properly
Usually if it's leaking from the filler cap and the engine is not overheating, then either the cap is not tightened properly, the rubber seal on the cap is damaged/faulty (get a new cap), or the spring in the cap for maintaining proper pressure is faulty (get a new cap).
it will overheat and pressure will open the cap allowing fluid loss which the air will evaporate
To properly air up a bike tire, first, determine the recommended tire pressure listed on the sidewall of the tire. Use a bike pump with a pressure gauge to inflate the tire to the recommended pressure. Remove the valve cap, attach the pump nozzle to the valve, and pump air into the tire until it reaches the desired pressure. Check the pressure with the gauge periodically to avoid overinflating. Once the tire is properly inflated, remove the pump, securely replace the valve cap, and you're ready to ride.
