On the Subaru oil pump, if you have the oem gauge, the port for the pressure switch is plugged, so you can just use an adapter and connect the mechanical gauge there.

The near center vs near battery are quite different.

Yes, that port is where you can install an after market gauge. Some of the gauge companies also offer adapters. I also know that Amsoil had a kit with them for the bypass filter.

Make sure you get a British tapered pipe thread adapter. That port is not metric, or NPT.

Oil pressure - the dash gauge may not be accurate, get a mechanical one for testing. There is a 1/8" British tapered pipe thread plug on the pump, near the bigger port for the gauge sender. Do not try to use a 1/8" NPT pipe fitting, or a metric one. Timing way off and choke not working will cause all sorts of trouble.

I have done a windshield or 2. Also had one of the places that comes to the car do it. Getting the old one out is the hard part.

There are 7 coolant system hoses on the EA82 engine. Be sure they are all not ridiculously old, and in good condition, including the pipes they slide onto.

There is also a weep hole on the bottom of the water pump.

Wow, how odd. I don't remember ever seeing any other than Japan.

The forum change did that, everyone had to get reset. Did you check the grounds? Previous posts had mentioned many trouble codes. That is not typical. Many of these parts are NLA, so it's hunting for the rare one in a junkyard, ebay, or finding someone who is done with them, and has leftover parts to get rid of. Some parts may be adapted from other vehicles, but I have not seen anything regarding the TPS.

Most likely to be NOS.

Yes, a newer different radiator might be a good idea. For all we know, the one in it may be NLA.

Look for German made cars for the radiator source. Not Japanese.

There are no solenoids under the dash. Those are relays. NONE of them operate the starter.

There is no relay in the starting circuit of these cars. The only solenoid is on the side of the starter motor, it throws the pinion gear forward to engage the flywheel.

Does not look like any Subaru radiator I have seen. But I have not seen all of them.

On the back of the starter there is a small wire. Unplug it, and get 12v to the terminal on the starter, to verify that the starter cranks. These cars did not have a starter relay, and it is common for one of several connections or switches in the circuit that feeds the wire mentioned above to become high enough resistance to make the startery not engage. Although, this usually begins as an intermittent click no crank problem.

It generally makes it easier and more useful for others down the road to make separate threads for separate problems. I have a Dynahoe 190, and have worked on a few backhoes.

The temperature sensor does not rely on the coolant for ground. While it isn't an insulator, water is a poor conductor compared to aluminum.

I have a dual range transmission available.

CHECK THE 15 amp fuses. Fuse box is behind a cover, lower left of the steering column. There is one marked "meter" near the center.

I am not 100% sure on an 84, but 86 through 93 are what I run - on these, this is the symptom that one of the brushes in the alternator has worn down and is not making good contact with the slip ring. It happens around 150k miles, like clockwork.

Only California has 8. The duplicate, I don't know. The link only goes to a "select part" kind of table, no way to tell. 86 could be carburetor, or possibly SPFI, I don't know exactly when they changed. I had an 86 carb, and an 87 SPFI. Sometimes it is easier to use the "contact us" link and let them sort out what they are looking for.

My 92 had those annoying seat belts. They were always flakey. My 93 has them, but they still work. When they get flakey, I'll install a set of pre automatic lap belts, I saved from a 1990. Yes, you want to try to find a FSM or scanned pages to download, as they have very complete schematics.

Some of the old R-12 systems are pretty good. Just a guess, maybe less worried about MPG back then, so rhe A/C might be sized more for cooling than efficiency. A/C is a few HP load, so it is noticable on a small engine.
