High Coolant Temp. On! Whitish smoke on the muffler! Check Engine light is on!

[nelson]

So to start up, just bought the unit a couple of weeks ago, brand new. When i got home, I parked it for a while then when I start it again I’m seeing whitish smoke coming out in the exhaust, I rev up the throttle still smoke is coming out, when i ride it There a High Coolant temp. Light comes on in the dash board so i stop and parked it back again in the house, the next morning I opened the radiator cap and its empty, no coolant inside the radiator but there are some in the reservoir. So I managed to fill it up and filling the whole radiator ( not knowing the proper way to bleed out the air) I ride it again and notice the Overheat light on again on the dashboard and the reservoir is filled with coolant , so i guess I did not do it the right way thats why its still overheating. Its in the dealer service center now and they are troubleshooting it hope they can manage to ressolve the issue.

I'd suspect a blown head gasket. Don't ride it. Call the dealer and describe the symptoms as you did in you post. They need to pick it up & replace, I'd demand a new scoot.

Did you check the oil level. IF blown head gasket oil should look like chocolate milk color.

[nelson]

Yes I check the engine oil.. its normal, and i can tell that its not the head gasket because I ran a test I start the engine while the cap is off and no bubbles apeeared so its. Not the head gasket.. So where you think the rest of the coolant went?. The reservoir is still the same in volume.

If the bike is loosing coolant... it's either leaking out or going somewhere inside the engine. Your check for bubbles from a blown gasket in the radiator is a good option, but not always fool-proof. If the head gasket's not leaking, it could be a bad water pump seal or something else...
But the lose of coolant and white exhaust smoke sure sounds like coolant is entering the engine's combustion chamber to me..

Nelson - A reply regarding what the trouble turned out to be would be helpful for the forum members.

I had a simular problem back in 2004. The water jacket in the head had a hole leading to the intake valve. I replaced the head using all the old parts (valves). Bike still runs great. I also now have a 2019 PCX 150.
