I am dealing with a hot engine

Hello,

There are a number of things that can happen if the vehicle gets driven while overheating. It can blow the head gasket, which will produce white smoke out of the tailpipe.
It can warp the cylinder head due to excess heat. Which if severe enough will not allow the engine to start as it will not have enough compression to start over.

Here is a guide on what to look for in case of a blow head gasket:

Overheating can also foul out the coolant temperature sensor. Which will also prevent the engine from starting.

First you need to check and find out where the coolant is leaking from.

Please let me know your findings.
Thank you.
