My 4 runner started overheating my coolant was low so I checked all my fluids filled all them up and still overheating. When I start driving within 5 min of driving I have alot of white smoke pouring out also my heater went out. I am stuck between replacing waterpump, gaskets, or if it is something internal. If you could please give me some advice I would appreciate it greatly. Thank you

You've probably already figured this out but if not it sounds like a head gasket problem. This particular model had a bad head design.

I'm not a professional mechanic but I have done my own head gasket repair and this sounds just like what I went through a couple years ago.

One thing you can do it pull each spark plug out and inspect the tip. If it is shiny or wet looking you've probably got a head gasket failure. There are other things you can do like a compression check as well. Does the white smoke have a sweet smell?

Try these checks and avoid starting it if you can.
