Fuel filter should be just in front of the fuel tank. There is also a filter sock in the tank on the fuel pump. Regulator should be at the engine near the fire wall usually in the fuel line. There should be a Schrader valve (like a tire valve) with a green cap on it this is where you connect a pressure gauge . It is between the engine and the regulator.

Check fuel pressure. If weak then either fuel pump or filter need replacing.

Hi. I would check that fan circuit to be sure of its integrity. Use the procedure below to troubleshoot:



1.Check for broken wires or loose connectors around the fan circuit. Inspect connectors at the fan motor, relay, sensor or heat sensitive switch, and the Electronic Control Module (ECM)--your car’s computer control system. Also, make sure to check for a possible blown fan fuse. These are common and overlooked troublesome spots that may cause a fan to fail.


2.Run and bring the engine to warm temperature. With the engine running, use a voltage test light to check for power to the motor fan. Be extra careful and make sure to keep your hands and tools away from the belt, fan or any other engine moving parts. If voltage is reaching the fan motor, the test light should glow.


3.Turn off the engine after you see the light glow. Apply direct voltage to the fan motor from your car battery using a pair of spare wires. If the fan fails to operate, replace the fan motor. If the motor operates, your problem is in the motor connector.


  • NOTE_ If you suspect a defective ECM take your vehicle to a service shop for a computer analysis. In most cases, the ECM is rare to be the cause of a failing fan. The above steps should take you to the root cause of your problem and help you fix the cooler fan.

The most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank(not the cap),this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.The hose goes in to the engine to a crossover and comes out the other side to near the thermostat housing,the blockage may be there.

It would be the water pump pulley and you remove the 4 bolts from the front of the fan and the fan and the pulley pull off.You'll probably have to remove the top of the fan shroud to accomplish this. They are 2 separate pieces. I'd check a scrap yard for a replacement pulley. They will need to know what size engine and what options are on your motor. Hope this helps.

The answer is no you will not be able to get it in the engine compartment and besides do you really want all the headaches associated with engine size diff.?
You are better off sticking with the same engine size, since the car was configured for that size.

Did you put the push rods back in same as they came out? On some they have short and long, like short for intake and long for exhaust, or visa versa. Thats what it sounds like to me, you got the push rods in the wrong spots.
