It is time to adjust the tappets as the weather is about to get warmer. Remove the two 10 mm bolts in the red circle. I should have taken more pictures, but there is also a throttle wire stay bolt in the front, so remove that as well (10mm x 1). Remove the two hoses that are stuck in the head cover. and the connector of the throttle valve switch. The connector can be pulled out by removing the U-shaped metal clip with a precision screwdriver. First, loosen the rubber hose band on the turbine side of the intake pipe. Loosen the hose band of the rubber hose on the turbine side, and push it into the throttle side as shown by the red arrow. and push it into the throttle side. Next, loosen the hose band of the rubber hose on the throttle side. Then, turn the hose band of the throttle side rubber hose about 90 degrees as shown by the red arrow. The intake pipe can be pulled out. Then, remove the two 14mm nuts on the head cover. The head cover will come off. Since the adjusting bolt had a pitch of 1mm. If you turn […]
Figaro has a hose to drain the water that has flowed into the gap between the trunk hangar and the hood. Most of the cases of this hose have not been replaced for 30 years. I think you should replace it immediately. If the drain water does not come out easily, it is highly possible that the hose is clogged. If it is not replaced, it has deteriorated like the state of the attached image. This hose is on the left and right, looking into the trunk. Looking at the removed hose, it was so clogged. Drain water does not flow. That’s why I will replace it. Prepare a hose with an inner diameter of 10 mm and a hose of about 2 m 20 cm. It is a silicon hose. The hose is fairly stiff, but pull it out while twisting it. There are two hoses, so pull out both. After pulling out both, pull up and pull out the lower side as well. After pulling it out, cut the purchased hose according to the length of the existing hose and replace it. When you have finished replacing it, put it back. It has a hose glamp, but it […]
Rust and corrosion of the body You can see the paint floating on the car body. It is due to rust and corrosion. After all there was a hole. That is also left and right. It is recommended to cut the rusted part and work with an iron plate, putty finish & paint, rather than just putty finish & paint. Rust and corrosion on the rear window panel This is a common event in Figaro. Watch out for Figaro, whose rear window panel looks like the image. When it was detached, it was rusted by 30 cm and was tattered and unreproducible. I knew in advance that it couldn’t be repaired, but I didn’t think it was 30 cm. The genuine product is made of iron and no parts are supplied. So I bought a window panel made of resin at the Figaro shop in England. I also bought a hood for replacement. There is also new rust and corrosion on the vehicle body side. There was a hole when I rolled up the rust. I will repair it here as well. The replacement and repair of the rear window and hood has been completed.
Have you ever experienced that when you cross a step with Figaro or Pao, hazards and blinkers turn on even though you are not operating it? My Figaro is so. Therefore, I am worried that the blinker will turn on every time I cross a step. First of all, pull out the lever of the switch. Next, insert a flat-blade screwdriver from below to remove the decorative panel in the foreground. Yes. After that, remove the ring, remove the connector and pull out the switch from the back to complete the removal. I removed the speedometer to ensure workability. The switch on the right is the switch that was removed, and the switch on the left is the switch that was purchased as a spare. As you can see, there is a gap between the base and the main body at the red line. If there is an impact due to this gap, the contacts will turn on without any operation, and the hazards and blinkers will be on. Seen from the side, it looks like this. The repair method is simple, crush the red circle with a vise. Crush it with a vise like this. There are four corners, […]
The natural enemy of cars, especially old cars, is “rust”, isn’t it? If you want to ride for decades to come, you have to protect the body from rust. I often see that the license plate bolts are replaced with stainless steel so that they do not rust, but it is half correct and half incorrect. Every bolt has a nut. The combination of stainless steel bolts and iron nuts causes dissimilar metal contact and attempts to promote the oxidation (rust) of the iron nuts. This is completely meaningless, so if you want to replace it with stainless steel, you have to use a bolt and nut set. For example, in the case of Nissan Figaro, the nut side (stay on the back) of the license plate is made of iron and the nut is welded and cannot be replaced, so it is better to make the bolt made of iron. Bare iron bolts will rust quickly, so use plated bolts. The introduction has become longer, but I will explain how to protect the body. Apply the dissimilar metal contact described earlier to mount the sacrificial electrode. Simply put, a metal that rusts more easily than iron is attached, and […]
I have overhauled the IAA unit several times, but when the electrical load increases, the idle up becomes unsuccessful. I got a valve at an online auction and came today, so I replaced it immediately. By the way, the IAA unit is an abbreviation for idle auto adjust unit and is an automatic idling adjustment device. Today’s cars do various things with one AAC valve, but Figaro has a configuration that makes you feel the transition period of the era of shifting from carburetors with three adjustment devices to injection. Immediately after starting, the air regulator is also involved, so it is a problem that there are many parts and many parts are fragile. For the time being, incorporate and adjust. The green circle is the basic idling adjustment screw. The red is the air flow rate adjustment screw of the idle-up solenoid valve corresponding to the electric load changed this time. Yellow is the air flow rate adjustment screw for the FICD (First Idle Control Device) solenoid valve that supports air conditioner loads. By the way, the method is to close the red and yellow circle screws with the lights and other electrical equipment off and the air conditioner […]
Nissan Figaro hasn’t been able to raise the water temperature for a while. I thought that the thermostat was stuck open and replaced it. First, prepare the tools. Prepare a 10mm box wrench and ratchet wrench, a flat-blade screwdriver and water pump pliers. First, remove the turbo intake pipe. Remove the drain bolt of the radiator and remove the coolant. You can access the thermostat by removing the cooling water pipe to the thermostat. For the time being, the intake port of the turbo is packed with waste cloth to prevent foreign matter from entering. Thermostat appears if you remove three 10mm bolts. The thermostat is oriented and the TOP stamp is on top. Just in case, apply liquid packing and install it, and then assemble in the reverse order. Put new coolant in the radiator, turn the engine for a while, check that the thermostat opens, check the amount of coolant, and finish! It took about 40 minutes.
Let’s replace consumables as much as possible for preventive maintenance. This is a new fuel filter. First, release the fuel pressure. Let’s remove the fuel cap. You should hear a “psss” sound when you remove it. If you don’t hear it, may have leaked pressure between the fill port and the tank. Next, release the fuel pressure from the fuel pump to the injector. The most common method is as follows.1. Pull out the fuel pump fuse.2. Remove the fuel pump relay.Then the pump will not turn, so if you start the engine in that state the fuel will not go to the injector and it will stall in a few seconds and the fuel pressure will release. But Figaro doesn’t work this way. About step 1,there is a fuse, but it also serves as a power supply for the engine ECU, so it is no good. As you can see, step 2 is troublesome because you have to remove the air cleaner, and there is a possibility that the outside coupler will crack due to aging. So there is the easiest way. Unplug the fuel pump coupler. The place is the coupler shown in the image that appears after […]
