It should work. According to my findings, most parts are interchangeable from year 1986 to 1997 on Nissan pickups.

Yes, lack of compression and fouled plugs too.

I would really be concerned about the antifreeze in oil, sounds like head gasket at least or head, block problem, even if you dont see antifreeze leaking, the engine can burn it and exit through tail pipe-white smoke or steam (beyond just cold start-up)

the oil light comes on from loss of oil pressure, this can be from two things 1. your oil pump is bad abd 2. your bearings around the crankshaft are bad. If the noise is coming from the bottom of the engine, Then the bearings are bad. If the noise is at the top then this could be the distributor. the distributor drives the oil pump, there is a shaft or a pin/tongue on the bottom of the distributor. See if it is broke. Also look down the hole and see if the pump is broke. It's hard to see but you can with a good light and mirror. Just a note, If your truck has had a knock for a while(like when you start it in the morningand it goes away in a few minutes or seconds) Then the bearings are bad. It's time to rebuild or replace.

Take the right front tire off and remove the sphash guard, using a rachet, couple of
extentions and a swivel head you can get to the starter bolts.
There is limited access and its a slow go, but not to bad.
I just removed mine from 1991 Nissan and had it rebuilt for around 100.00 dollars.

Teeth could be broken on overrunning clutch on starter. If you cant get the starter to engage you will not be able to get the engine turned over.

Inspect/Replace If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing

• The heater housing is usually under the dash and must be removed to gain access to the heater core.
• Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

The heater housing is disassembled to get to the heater core. Heater Core

• Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
• Remove the heater coolant hoses.
• Remove the cable and/or vacuum control lines (if equipped).
• Remove the heater core securing brackets and/or clamps.
• Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
• To reinstall the heater core, reverse the removal steps.

When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

YOU WILL HAVE TO ACCESS THE SENDING UNIT ON TOP OF THE TANK TO SEE THE LINES.
IN ORDER TO DO THIS YOU WILL HAVE TO TAKE THE BOLTS OUT OF THE BOX SO YOU CAN MOVE THE BOX FORWARD SO YOU CAN ACCESS THE LINES TO MAKE THE PROPER REPAIR

I'd take a look up near where clutch pedal pivots for a switch similar to brake light switch, that has to be depressed or released by pedal when pushed. Probably a safety feature to insure vehicle won't start unless clutch in, just in case it's in gear. May be adjustable, but if not, or adjustment doesn't help, replace it.

on a chevy one time water was dripping down off the body and other areas which was right on top of starter and in very cold temps it would freeze up. i would get a propane torch and heat it up a little and it would start. it is possible the selonoid has moisture in it also which is reacting same way

NO its not correct if the belt has grooves they always face the pulley the belt has a V shape to it and so dose the belt the groves are to stop slippage between the pulley and belt

The tail light is molded in one piece. If your looking to replace the bulbs, there should be an access panel inside the pickup box behind the tail light. The whole tail light assembly can be removed from there as well.

you can get one from nissan, or you could take the bolt to a machine shop and have one made, or the junk yard. thats about the only thing i know of.

hate to give bad news but that is typical of a bad throw out bearing. either installed wrong or not at all. i would take it back. hope that helps please rate.

you need to take off the tire and pull the starter thru the wheel well.

Stop driving it
