The fan connects to a temperature sensor, unless it's been bypassed. This sensor should be checked first.
That is the temperature sending unit for the engine coolant and it should be in the drivers side head between the first 2 spark plugs.
Can a v.8 5.7l 350 engine fit into a 1994 Pontiac firebird?
usually on the left of the engine between the first two spark plugs
350 tbi
If this vehicle has the factory fan shroud it should say on it if you can still read the stickers on top of it.
yes you can swap the 454 for the 350 its compatible usually any Chevy engine will match in the same vehicle might have to do sum fabrication but in ur situation you should be fine
No they will not.
200 hp
The oil drain plug on a 1994 Chevy 350 is on the underside of the motor. Look for a bolt in the very center of the bottom of the engine.
The 350 cubic inch (5.7 liter) pickup engine was factory-rated at 200 horsepower in 1994.
You need a 350 TBI/Throttle body injection engine. This is the years you need to look for and they will ALL interchange. 1987 to 1995.
