I removed alternator and took out sensor behind thermostat housing and below about a foot. Only for engine codes cpva, cpvb. Pretty much the same thing.

Here is a guide that will give you an idea on what you are in for i purchased one.

In this system, the direction of cooling water flow is upward from the cylinder head to the top tank of the radiator, then down through the radiator core to the bottom tank. When refilling the engine coolant, the radiator cap should be removed and the system filled. Refer to water pump replacement (4.3l engine) in engine cooling. Does anyone happen to have anything that shows the coolant flow thru the system?
