92 Air pump
Good evening all,
I found an "unused" connector in the front drivers side, found out (from this GREAT board) that it was the relay for the air pump. I put a new relay and can hear the pump run. I also no longer notice a fuel smell when I start her up
My question is would the air pump cause the engine to run hotter? I noticed that normal for my LT1 is about 198, after the pump was hooked up it ran at 215..
Is this possible?
thanks

I had an out of the box thought regarding a correlation between the AIR pump and higher engine coolant temperature. Hat tip : @VikingTrad3r he reported this on one of his cars:
A clogged or restricted cat converter can cause elevated operating temperatures.
If the AIR pump is running at all times (It is not supposed to. Only for a brief period after engine start) the secondary air in the exhaust will cause elevated cat converter temperatures, and may damage (melt) the core.

thats an interesting theory about the pump running continuously. maybe thats why it was unplugged. a guy could use a laser temp gun to get a reading on the cat with it plugged in and not.
