Replacing some injectors and noticed on the throttle body there are 2 larger hoses that connect to it on either side near the bottom. Are these coolant hoses?

Heard you could take off the manifold collector with the TB attached, but don't want to leak coolant everywhere.

 

Yes,they are tb coolant hoses...They wont leak much coolant when you disconnect them..When you do remove them,have a bolt ready to stick in the end of it to block coolant from leaking..

 

Thanks for the help, found that out just a while ago. Not much leaked out since the engine was cold. Now, just gotta figure out how to get those 2 injector screws out holding in the injector. Looks like they just are going to strip out.
