A lot of white smoke comes out the exhaust

Toyota Sienna 2013 LE 170000 miles
I changed the coolant sensor and all six spark plugs but there is still a lot of white smoke that comes out the exhaust and the car overheats. The engine light is on and it says cylinder 2 and 4 misfire. The coolant keeps disappearing too it is not on the ground leaking but it keeps finishing.

I can confirm the coolant does not leak out the bottom, but rad needs fluid every 4 months or so

Have a 98 Sienna, crazy everything you described sounds exactly like what is going on with our van. Only with ours seems like the oil runs out fast but there’s no leak.

Overheating

Toyota Sienna 2012 Xle  112000 miles
Did the alternator and had to takeoff one of the radiator hoes to get to the alternator. Cooler came out, topped it back off with coolant and try to bleed the system, but I noticed the bleed screw is a little bit loose. Not sure if that’s my problem.

Heat only drivers side cold air blowing out the passages side

Toyota Sienna 2007 Sienna  200000 miles
Okay so I replaced the water pump and new coolant at first was blowing heat out of each side once it warms up now it’s only blows heat out of the driver side while the blows cold air from the passenger side
