I performed the throttle body bypass by connecting the hose from the radiator (just below the fill cap) to the long steam tube that runs down the passenger side valve cover. Where that tube curls around and goes back into the block, there is a large bolt, and ever since I did the bypass I have coolant coming out from around that bolt. It's dribbling everywhere while the car is on. What could be the cause of this and how's the best way to fix it?

Did I do something wrong? I'm thinking maybe I read wrong and I'm forcing coolant down a tube that's supposed to supply coolant causing a buildup of pressure therefore causing that connection to leak.

 

Try gently tightening the bolt on the back of the head... see if that stops your leak. It may have worked itself loose.

 

The throtle body bypass is a very easy procedure, the two hoses that need be addressed are 1) The hose entering the throttle body on the bottom and 2) the hose exiting the throttle body on the bottom. If you did this correctly, you will have patched the aforementioned hoses together, effectively bypassing the throtle body. There should be NO hose connected to the throttle body at this time.

Check your temperature, regardless of what it SHOWS, bleed your coolant system.

1) Start vehicle
2) Locate bleeder screws on coolant hardlines (easy to spot, theres two that need to be addressed).
3) GENTLY turn the head of the bleeder screw until coolant seeps out.
4) Tighten the bleeder screw.
5) Repeat steps 2-4 on second bleeder screw.
6) Your coolant system should now be purged of all air (bled).

I hope this information helps.

This method is correct for 93-4, but not for 95-7.. [ there is no need for the coupling on the 95-7's..]

 

Yeah, that was confusing me. There was no "other" hose to couple to.

Anyway, I found out I was wrong, it was leaking at the radiator hose and steam pipe connection, I just couldn't tell. Thanks for the input guys.
