if thermostat is installed backwards what damage can it cause, would heater work
While it is a little difficult to install the Thermostat "backwards", the Thermostat typically would open "IF" there were sufficient Coolant, but would open lateThe Heater (heater core) would still circulate "when" the Coolant moved "IF" the Thermostat opened
If the Heater (heat) is the main concern, the Heater Core could be clogged & need flushed (50/50 chance of clearing) or Replaced, or it can be the Air Door not closing to allow Heat
Checking "both" Heater Hoses for equal heat, after the engine has reached Operating Temperature, will let you know if the Heater Core is clogged

Can it damage engine or, and how could I tell
yes, as the Thermostat controls the Coolant flow into the Engine to maintain Operating Temperature. Installing incorrectly can cause restriction, which can result in "overheating"
If you are "unsure", your best bet is to take it apart & check.Gasget should be all you need for parts
