Why is the muffler puffing white smoke and whistling when my radiator went out so I changed it but then the fans will not kick on still and now the car is bogging out

Hello, white smoke is often indicative of an internal engine coolant consumption issue, such as with a cylinder head gasket or cylinder head breach. This is a guess from a symptom alone, but based on your other symptoms is plausible. I would recommend having the engine and vehicle assessed at a trusted shop near you to see what's going on first hand. The cooling fan, radiator, temperature gauge may have been and may still be issues, but they can also contribute to larger problems such as internal engine ones.
