Omar Posted August 31, 2007 Share Posted August 31, 2007 so i went to change my coolent temperature sensor on my l28et. at first i couldn't find it. then i saw this unti that looks kinda like it(at least the clip was the right fit). i proceeded to try to take it off and it snapped. it is not made to be removed b/c there is no threads. oops. 1. what is the piece called that i broke the sensor off of? 2. wtf does it do? (its got this spring loaded port with a sensor inside) 3. is it the same on an n/a l28e? came from here Quote Link to comment Share on other sites More sharing options...
Mr.INSANE Posted August 31, 2007 Share Posted August 31, 2007 I think thats the auxiliary air regulator It makes the motor idle higher until its warmed to operating temperature Quote Link to comment Share on other sites More sharing options...
tommyboy Posted August 31, 2007 Share Posted August 31, 2007 Hey bro. That's the Air Regulator. It bypasses the throttle valve, to control the quantity of air required for increasing the engine idling speed when staring the engine at an underhood temp. of below 80 degrees C. (176 degrees F.) Here are a few pics from my service manual for what you might be looking for. The thermotime switch works in conjunction with the cold start valve, so that's not it, even though it has the same plug type. I think that the part you're looking for is the cylinder head temp sensor. (this also has the Bosch style plug). Here's another pic (where it is on the engine) from my manual. I know it's blurry, but the sensor is located on the passenger side under the spark plugs and above where the dipstick is. Hope this helps.

Omar Posted August 31, 2007 Author Share Posted August 31, 2007 that's very very helpful. now I just need to know if the n/a has the same on. b/c that can be had at the yard for almost nothing.

tommyboy Posted September 1, 2007 Share Posted September 1, 2007 that's very very helpful. now I just need to know if the n/a has the same on. b/c that can be had at the yard for almost nothing. (no turbo Z at the yard) problem fixed. thanks man. It should. The N/A and the turbo ZX's are pretty much the same when it comes to coolant stuff. Just check the thermostat housing and the back of the cylinder head to see if they're the same. Hope everything goes well!!! Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted September 2, 2007 Share Posted September 2, 2007 It looks a little different than my 280Z as far as the coolant fittings and whatnot but I think it'll end up the same. Quote Link to comment Share on other sites More sharing options...
kastmaster Posted September 4, 2007 Share Posted September 4, 2007 As someone who does own an l28e stock, yes it is the same. And yes, to put my two cents in with everyone else, that is indeed the air regulator. Just wanted to further confirm that Quote Link to comment Share on other sites More sharing options...
