True, but I thought about putting on a high amp draw fan from a taurus & assumed it may do unwanted damage. The same company I mentioned in that link also makes an externally mounted box with 3 rectifier bridges to add serious amperage also. I started thinking about what another local enthusiast told me & then I found their website again and saw that & a lot more that looked cool. I have used their alternator rebuild kits with success, so I trust them so far. It made me think and that is all I am really saying. As for the temp hose adapter from stinger, it was too small. Not a lot, but enough to make me wonder if it would really leak. I am off to the hardware stare today to find something out of the plumbing section made of some kind of metal that I can make myself. I figured a brass pipe of 1.75 inches with 2 loose compression rings that I can sweat on with solder to make the hose stops, then sweat in a bung threaded correctly for my sensor. The stinger is 1.5 inches but the hose has an inside diameter of 1.75 inches. Not much, but I like to get it right first time. I found that Jegs sells an in line hose drain that could double as this of the correct size, but I no longer have $20 plus to spend on that. So, off to Home Depot I go. My word of caution to you guys, if you do the in line temp sensor adapter, go with the in line hose drain thingy from Jegs, it is at least the right size.

 

Peshewa, you can add external regulation if you are worried about it but it probably isn't necessary even with a really high draw fan. The battery will add current to the circuit during transients and protect the voltage regulator. If you do add an external unit either disable the oem one or diode protect them so the stronger one doesn't swallow the weaker one.

Regarding the Steiger adapter, your post had me cussing until I grabbed my calipers and double checked everything. In the non flared section of radiator hose I'd planned to splice this thing in there is approximately an OD of 1 and 7/8" as measured by my calipers. The hose wall thickness is around 1/8". This means the ID should be about 1 and 5/8" which should be fine with a 1 and 1/2" OD adapter IMO. It's going to be fine that way man.

 

Correction on my last post. This was bugging me still so I went out and remeasured hose wall thickness using a ruler since I couldn't really measure it with my calipers. New reading is 3/16"... new math" 1 7/8" - 2*(3/16") = 1 1/2".

The Steiger adapter is going to fit like a custom tailored glove.

 

You are right - they sent me a 1.25 inch unit even thought I ordered the 1.5 unit. Small mix up but the fix is already on the way.

 

Uh, guys.... How are you going to ground the switch? It's a single post switch isn't it? That means it wants to ground thru the body of the switch, gonna have to run a ground wire for your hose adapter.

 

There are two adapters from Steiger. One for the smaller 1 post sensors which ships with a ring terminal that fits on the sensor body. You can ground it with the ring termianl.

There is also the other adapter which takes the two post sensors.

I bought the one for the one post sensor that comes with a ring terminal since I already had purchased the smaller sensor when I bought the adapter and the sensors are like $30.
