Koyo install questions
I bought a koyo about a month ago, and spent the rest of the time sourcing the relay kit and such for my e-fan install. When I bought it, it didnt have the bottom drain plug, and the bleeder one looked really sketchy. I tried to use the ones from my stock radiator as a direct replacement, but that did not work.
I looked around to see if I can find a site that just sold the plugs to get info on the size and such, but to no avail. Does anyone know the size of plugs I need for the drain and bleeder?
Also, it seems that the prongs for the sensors for the Radiator switch connector (if I'm reading the FSM right, thats what it is called, bottom of the driver side, 2 sensors hook up to it) have been snapped off. I tried to wrench it off but I didnt want to break my radiator trying to remove it. It can be removed and replaced, correct? I wanted to use the other one from my stockie.
If those sensors are not a big issue, then I wont worry about it. I'm unsure what they are used for. Help for the above questions is appeciated.

M10X1.25 is what I've got for my air bleed screw, but in a related thread another mentions M10X1.5 for their rad.
You might have to do some trimming to the bolt so it will be narrow enough to fit the ring and the head short enough to clear the hood.

So I've heard some FC's came with their stock radiators being koyo brand. I also hear their plugs should fit in...any truth to this?
Also, nobodys really elaborated on the radiator switch connector thing, I'm curious if it's necessary.

And the switch at the bottom of the radiator can be bypassed. Jump the two wires together, and tape them up. Without the thermoswitch, you should lose the 3k RPM startup, but also have the potential for cold starts (under 65*F) to be harder. I disabled mine for a few weeks and saw no difference (I already don't have the 3k RPM warmup). Winter might be a different story though.

Yeah, thats what I was told as well. Either mine isnt OEM or they are wrong. Well it's definitely m10x1.25 fine thread. Problem there is, you go to an auto parts store, they ask you the make and model of the car. Well thats not helping me. I went to a hardware store, they had socket head screws, but they were m20x1.25. I think they will work but they didnt have the length I needed.
On another note, I called koyo, but it seems you can only get ahold of their wholesale dealers. Let me try another number.

Go to a Subaru Dealership, they have it by part # 745124050
They say it's for a 92-98 Legacy, other cars, etc. What do you know, I have a legacy in my front driveway! I might have to test it.

It also has a nissan part #, call your nissan dealer to see if they stock it. Subaru nor nissan had it, so I'm calling another auto parts store.
Nissan #21480R0100

btw if you break the plug in the radiator do not drill it out, what I did was take a long flat head screwdriver and I heated the tip up with a propane torch till it was good and hot, then inserted it straight into the plug a little bit so it melted its way in. I removed the screwdriver and cooled it off in a bucket of water, then after a few minutes turned the drain plug out nice and tidy like. Did not even have to get under the car for it or remove the undertray.
