coolant sensor with ATR headers?

[jjorgensen52]

It appears, after installing my atr headers, that both coolant temperature sensor and another unknown port in my new vortecs are partly covered. I'm capping the one as it has no function, but on the oher head how do I get the temp sensor in? Cut the header flange?

usually people just notch the flang. Can you use the port on the passenger side head instead? Or is that covered also

both covered. I figured notching was all it would want. Last little bits of assembly going on now :tup: (but my dyno time has been bumped to next monday :tdown: )

wel that'll give you plenty of time to cut a nice perfect circle or dremel it to be like 1mm around the sensor

is it possiblee to put the knock sensor in the other port?

does the knock sensor enjoy hot water?

I need to find a plug for that other port. Anybody happen to know the thread / diameter of the sensor (seemed like it was a metric to me but it wasn't anything normal that I could find )

my ty came with a broken temp sensor being used as a plug :lol: Just take the sensor to autozone/advanced auto and get yourself the right sized plug. Its a common size.

turns out to be a NPT fitting :roll: ... anyway just need to find a good flush plug for it and I'll be all set

drill and tap the intake on the drivers side rear corner where it meets the head above the water jacket. then you won't have to re-run/extend the wiring.

on LT1 cars the knock sensor is in the side of the block in the water jacks, my CPI 4.3 also had it there. im just asking!!!!

i was just asking also. Some sensors aren't meant for water...wasn't sure if knock sensor would be one. Especially since sound travels through water differently than through air.

oh ok sorry.... from what ive learned they can and sound travels better in water ( might not be a great think but it better thn getting knock from the trans.

Also you seem to be my late night question answerer... respond in my push rod post Renz

yea and depending on the sensitivity of the knock sensor, water sounds may be too much.
