Thermostat change how do I drain coolant from 1996 nissan pickup to change thermosatat

Sounds like you still have air in the system. Is there a little bleed valve on top of your thermosatat housing? That is for getting air out. If it doesn't have one: take radiator cap off, turn heater to full hot (not the blower motor, keep that off), start car and let it reach normal operating temperature. When thermostat opens, add coolant as necessary to radiator and to overflow tank. Replace cap on radiator. Good luck.

You refill the engine coolant by filling the overflow reservoir/pressure tank.Start the vehicle and keep filling until it reaches the full mark,then allow the engine to get to operating temp of 190 degrees and then top off the coolant.There is no bleeders for this engine unless you have a duramax then there is a bleeder on top of thermosatat housing that you remove with the engine off and fill the coolant until it comes out of the bleed hole.Start the duramax engine and let warm to operating temp.You may need to hold the engine speed at 2000 rpm to get the diesel to operating temp.

It should be at the front of the engine where the upper radiator hose is attached to the engine. The radiator hose will be attached to the thermostat housing with a hose clamp. The thermostat housing should have two bolts holding it in place. Remove the gbolts(engine cold) and raise the housing up, The thermostat will be underneath. Make sure the new thermostat is facing the right way when you install it, Don't forget the gasket. Bolt the housing back in place and install the radiator hose and clamp. Replenish any coolant that was lost to bring the coolant level back up. Run the engine long enough for it to warm up. Check for leaks, monitor the temperature guage to make sure it reaches normal temp without overhearing, and make sure the heater is blowing warm air.

remove the air cleaner and air duct assembly then remove the radiator hose then the water inlet housing remove the thermostat from the housing make sure you disconnect the battery ground and drain the engine and radiator coolant. So its located behind the water inlet housing attached to the radiator hose

Look at the upper radiator hose follow it down to were it clamps to the engine This part is called the goose neck Thermostat is located under it and what you need to do is first drain some antifreeze out of the radiator a QT or so remove the hose clamp remove the hose remove the two bolts that hold down the goose neck the t stat is under it lift it out clean off the old gasket real good its important to getting a good seal with the new gasket and not cracking the neck when your reinstalling put new t stat in put new gasket on you may want to put some sealer on it then reinstall everything else in reverise order don;t over tighten goose neck bolts about 18 ft lbs

Where the top radiator hose attaches to the engine, there should be 2 or 3 bolts to remove to take the hose connection off the engine. The thermostat goes in between the hose connection and the engine. If there isn't a thermostat there then I would guess that it was removed and driven without a thermostat.

Follow the top radiator hose. It goes right to the thermostat. Make sure that the little hole in the new thermostat it up when installing.

Follow the top radiator hose to the housing where the thermostat is likely to be located.

the thermostat housing is located where the radiator hose connects to the engine. you'll need a flush kit to flush it out, it comes with instructions

There is a small bypass hose for the thermostat. Are you asking how to do a complete flush? If you want to make sure you get all the coolant out there is a 14mm drain plug on the left side of the engine block that will allow all the coolant to drain. It is tough to get to without the right tools. Make sure you remove the small bleeder screw on the thermostat housing when refilling so all the air is purged from the system.
