me and my brother taken manifolds off his 305 tbi, and on the passenger side as i was pulling the mani out this broke could off... could someone tell me what this is for and will it be ok to bypass? while were waiting for the headers if its needed i will replace it.

 

It looks like the coolant temp sensor.
Back the camera up a foot or so to get a better picture.

 

i agree, it's the coolant fan switch if it's the passenger side (looks like a starter to me). should be on the other side of the head by the spark plugs if it's what we're speaking about.

As mentioned, if it's in the passenger side head, it kicks the coolant fan relay/ECU a signal to engage the radiator fan, only way to bypass this is with a switch to activate it, or leave your a/c in the on position at all times otherwise your car will endefinally overheat as those two things will turn the rad. fan on.

 

ok thanks guys

 

You can get a new one at a auto store for dirt cheap, and it looks like the clip is fine so all you really need to do is get a new temp sensor

or you can go after market - good luck

 

ok i fixed it two where when i turn his key on the fan kicks on screw paying the 10 dollars for a new one call me a cheep bast*** but times are hard

 

yeah its much cheaper to buy a whole fan when it goes out from constantly being run plus the gas you'll be wasting cause it'll take longer for the car to warm up and you will be in open loop.

 

bro calm down lol its my brothers first car and when he gets a job he will prob get one i meant for now

 

my bad..sorry..one too many energy drinks today

 

lol but thanks for yalls input cause i was going to leave it like it was doh
