Nissan knew what they were doing when they built this truck
The only things that have gone wrong with the truck were the starter, radiator and alternator.
The "swirl valve" is a different story.
The radiator was simple and only cost 47.00 on eBay.
The starter was a little more challenging, but doable.
The alternator was easy to replace also.
The swirl valve is difficult. If you have the "Service engine soon" light come on and the code P1130 comes up on a OBD2 scanner, you are in for some real fun.
For starters, let me make life easier for you and tell you where the swirl valve "really" is on a 1997 Nissan pickup. The swirl valve is located between the firewall and the back of the engine valve train cover. You will have to take off the air intake cover to see it. It looks like a small silver vacuum actuator with one vacuum hose connected to the bottom of it. The swirl valve is connected to the back of the engine block by a bracket. Removing the engine hoist pick point makes thing easier to work on. You will need a box end wrench for the pick point and a right angle #3 screw driver to remove the two screws that hold the swirl valve in place. These can be seen with a mechanic's mirror. There is also a E-clip connecting the top of the actuator to the control arm that goes into the throttle body.
I spent my Saturday and $125 bucks on a swirl valve finding out how to do this, so my truck could pass smog. I did not want to pay $400 for a mechanic to fix it. Once I replaced the swirl valve, the light went out and I passed smog. Found out later that the swirl valve can be found on eBay for $75. I used a genuine Nissan part. The part number is "14517-86G0A Actuator-Power". Good luck.
Don't let the size of the truck fool you, this is a tough little truck. The rear drum brakes are the same size as a full size truck. I use my truck as a daily driver, and also for side work. I have had the whole truck bed packed tight full of 6' fence pickets up to the edge. The truck rides a little low, but gets the job done.
I bought this same truck again because I used to own a 1994 Nissan pickup that I drove 100+ miles to the navy base and back every day for 10 years with zero problems, only regular maintenance and a battery. "Very reliable".
Would you buy another car from this manufacturer? Yes
