Was wondering where the thermostat is located and if it is very hard to change? Need to get it done tommorow

You want someone to tell you where the tstat is without telling us what engine it has?

My bad 2.3 4 cylinder .i found it after getting the part

is this a 2.3 lima (older engine), or 2.3 duratec? or rather, what year is your truck? the duratec is what they put in 2001 and up.

It's a 2002

i'm guessing it's on the top/front of the engine in a housing that meets to the block, and has the top radiator hose going out to the radiator.

i've heard of some people having to go lower, near the water pump to get to theirs on 4 cylinders, but i don't know

free bump anyways

To find the duratec tstat, it's what the lower radiator hose attaches to. $100+ part.
