You did not say what year it was. But if you look back by the distributor were it goes into the intake manifold, just a few inches behind the distributor you will see it.
where are the temperature sending unit located on a 1990 Chevy engine 5.7
fords don't have a 350 the 350 is a Chevy motor
At the back of the block, near the distributor.
In back of the engine, on top, drivers side, next to the distributor.
if it is an 350 eng it is located at the rear of the intake manifold,on the top of the block, next to the dist.
I will doubt the connection or the sending unit. Hope this will help.
From 1956 until recently it has been located at the rear of the engine between the valve covers hidden behind the intake.
It is located on the drivers side right above the exhaust manifold towards the front/next too the first exhaust port
It is right behind the distributor. It is HARD to see and to get to.
Back of the engine, on the top next to the distributor.
It is the switch at the very back of the engine where the engine and transmission meet. and just to the driver's side of the distributor
On a Chevy 350 engine, the oil sending unit is typically located on the engine block, near the oil filter. It can usually be found on the driver's side, towards the back of the engine, and is often threaded into the block. To access it, you may need to remove the oil filter or other components for better visibility and reach.
