what is the plug at the bottom driver side 4 it has to wires that go in too in radiator i broke 1 wire

 

It is what causes you car to rev to 3,000 RPM's when you first start it. What it does is sense teh tempeture and once it warms up a little it will bring the RPM's back down. Just go ahead and unplug the other one, it won't make any diggerence in the car other than it shouldn't rev to 3,000 RPM's when it is first started.

 

Yup, water temp switch... Controls the AWS.

As HAILERS puts it, "not a safety of flight issue"

But there are unintended consequenses to the removal of the wires or the sensor other than emissons cold start.

The removal of the sensor or wires WILL result in the Relief solenoid not working on schedule. (emissions related only).

Explanation here: Normaly the Relief solenoid will not de-energize until you hit 3800 rpm. There are exceptions but not worth talking about. The relief solenoid controls when the ACV *dumps* air overboard into the silencer.

If the water temp switch on the radiator is disconnected....and say you had a LED connected to the Relief solenoid....you would notice as you were driving that the LED will be lit at idle, but once you are driving the LED will be off way prior to 3800 rpm. The system was not designed to relieve before 3800 rpm (with exceptions). So the emissions won't be working as designed.

I noticed this a while back. I had two led's in the cabin. One for the Relief solenoid, one for the Switching solenoid. Normal operation would show the Relief solenoid LED light ON until 3800. One day I noticed the light was on at idle, but as soon as I started driving the light went out. What's amiss I say. Well it turned out I forgot to reattach the wires to the switch at the bottom of the radiator, that's what.

If the thing is disabled, you will never notice it by just driving the car. No symptoms at all. If you go get your car emissions tested, and they put the car on a threadmill and accelerate the car to different speeds while checking the exaust......the sniffer WILL notice. Because most of the airpump air is not going to the exaust ports....but going overboard to the silencer in the right front fender.

The above is just a series four *thing*. Those series five ain't got none.

LIke I said *not saftey of flight item*. Car will run just dandy without it. But beware of the side effects.

 

Is there a certain way the wires plug in???? I noticed a dot in between the 2 post.

Also does it matter how far that plug is inside the radiator?? I just put mine onto a Koyo and it seems it only went in almost 1/2 way.

Listen to HAILERS. he's a smart, smart man. damn dude.

i was gunna come up with an explination like that. good work.

Can anyone answer this???

 

I don't think it matters which way that they plug in, and there will be water on the sensor wether it is half way in or all the way in so I dought that that will matter.

And also with it being unplugged for me it wouldn't matter because I don't have any emmissions crap on my car.

 

When i look into the hole the switch/sensor goes into, at the end its sealed or closed off. How will water be getting to it?? Am I suppose to pop a whole in that seal??

Thx

Water wont get to it, it just senses the heat of the radiator. Its basically a dumb sensor. Open or closed at a certain temp.

Ohh, I thought water toughted it. I'm on a role for getting corrected today.
