No heat

there is no coolant circulating thru radiator & the coolant temp while driving is only 159 but when you stop the temp climbs to 210

no coolant circulating thru radiator

Start by replacing the thermostat for this type of problem.

Tester

the engine does not come on when it reaches 199

What does that have to do with replacing the thermostat?

The engine does not come on when it reaches 199 ??? What kind of information do you think you are conveying with that sentence?

the engine does not come on when it reaches 199 ???

You need make sure the radiator is full with proper mix and type of coolant, check when cool. 199 is not outside the range of normal. When the radiator and system are full of the proper fluid the thermostat controls the temp. By saying the engine does not come on, does it die or not start?

you mean the coolant fan does not run
