ok so i recently found out that the cooling lines that hook up to my throttle body are missing and i have no idea where im supposed to hook them up and what im supposed to get from the parts store so i can hook them up, i have an 87 firebird with a 5.7 tpi

 

Hey did you ever figure this out? I just realized my car has the same issue...except the line next to the thermostat housing runs down to a funnel that's screwed to the air dam, and the one that comes out the passenger side is just a cut off hose.

 

One of the Pass side of the TB goes to the heater switch. The stock hose on the bottom of the TB is in the shape of a "U". Comes out of the TB, 180* to a nipple in the front of the IM.

 

You shouldn't need a TB heater unless you plan on driving when the temp is below zero. Their only purpose is to prevent the TB from freezing.

 

Thanks Keoman. So is that all those hoses are is a tb heater? Why would the PO put that hose/ funnel deal on there - maybe some attempt at a cold air intake to cool the air going through the tb? Can I just cap these off to make it neater or is this rig actually doing something?

 

Yes it is for heating the TB. If you are going to bypass it, I would suggest this route.

You may run into problems in the sub 32* temperatures this way however.

 

Great, thanks again!
