i got a 94 teg ls...
i was driving on 5th gear and then my temp gauge goes down to 1/5 on cold..., i put air going circulating cabin and the temp gauge goes back up to 1/3 which s/be normal temp.

is there something wrong w/ my gauge or is it something else? y would it be running cold instead of running hot? I saw coolant leaking out of radiator cap so i bought new one, but this still happens...

pls help, thank you.
