How do you change thermostat on 95 firebird?
Remove the air filter and the intake elbow. There will be a vacuum line that connets to it comming from the distributor, this needs to be removed from the elbow. Next you will see the water pump with hoses going to it. There is a hose going to a kind of round housing bolted to the water pump. This is the housing to the thermostat. Get some towels to catch the coolant that will come out. Unbolt the thermostat housing and remove the thermostat. Make sure you angle the hose up to reduce the coolant comming out. Remove all of the residue from the old thermostat and put the new one in its place. Bolt the housing back on and reattach the intake. Don't forget to reattach the vaccum line. Run the engine and bleed off the coolant. Readd coolant as necessary.
