Best Answer

Just had this done. Model/ year the same. Must remove rear seat. There was a cover plate with 4 bolts. Remove bolts/plate. Will see gas feed and return line. This is connected to the gas tank float sending unit. Remove all screws and lift out the unit. The fuel pump is just off to the side and below the sending unit. It is secured in the tank by a cradle that fits around the body of the pump. Disconnect all hose and electric connectors. Should lift right out. Mark all the hose and connectors so you do not do a bad hookup. Only problem was a "O' ring that swelled at the top of the gas tank that prevents vapor. You "do not" have to drop the tank to do this. have all the doors open and KEEP ELECTRICAL OUT AND USE nothing that would spark gas vapors. Hand tools can be used but do not create or have any source of ignition. Gas vapors will be going into the interior of the car if you do not drop the tank. Should be 1-1 1/2 hours if all goes well.

For the 1988 1.6 and for most cars, follow the top radiator hose from the radiator to the engine block. Remove the hose from the engine block then remove the flange the hose was connected to (usually 2 bolts but may be 3 bolts on the Nissan). The thermostat is behind the flange.


Where is the solenoid on a 1995 Nissan Sentra E?

If it is anything like my 1991 Nissan Sentra (and it probably is), the solenoid is actually attached to the top of the starter. The starter is located underneath the car, attached just below the engine block but on top the transaxle (where the transmission connects with the axle) it is very difficult to get to, on mine I had to remove the air-intake manifold and a few mounting brackets below the car.
