2001 Oldsmobile Bravada oldsmobile bravada coolant leak

I need to see a pic of the part to identify it. Can you upload one for me to see?

If the engine is hot, it can go into a safe mode which will cause a power loss. Can you tell me if the check engine light has come on?

Thank you for your help, I'm attaching pictures. It's not a hose after all, it's metal and bolted down...any help is appreciated...

Also, an actual check engine light has not come on, but it did have a service engine light come on, not sure if it's the same...thanks so much

ok, found out that the part is the thermostat coolant housing outlet. I just need some direction on how to replace this please...thank you

Remove the necessary coolant from the radiator so that the level is below the t-stat.
Disconnect the neg battery terminal
Remove the alternator
Loosen the outlet hose clamp at the thermostat housing.
Remove the outlet hose from the thermostat housing. A clamp will be holding it in place.
Remove the thermostat housing bolts.
Remove the thermostat housing from the engine block. NOTE: You may have to gently pry the housing away from the engine block. Be careful not to break anything.
Once the housing is removed, you will see the thermostat. Pay close attention to how it is positioned (what is facing toward the engine) so that you put the new one in the same way.
Clean all of the surfaces of the thermostat housing so there is no gasket material left on it.
Clean the sealing surface of the engine block as well.
Correctly position the new thermostat into the engine block. NOTE: Make sure both steel surfaces are clean and dry.
Replace the housing and reverse the directions.

If you have trouble, let me know.

NOTE: Based on the pics you sent me, I assume this is the 4.2L engine and not the 4.3L. If that is incorrect, let me know. Also, the thermostat housing bolts should be tightened to 89 INCH POUNDS.
