throttle body question when i unplug the coolant line from the radiator do i need to plug the pipe on the throttle body also when i disconnect the 90 degree hose that goes to the side of the throttle do i need to plug it already hooked the hose from the radiator to the piping from the block don't know if these would be vaccum leaks

 

No vacuum leaks...remember coolant flowed through these passages. I put some rubber caps on my to keep the spiders out

Brought to you by shoebox. Just cap the throttle body passage. You will be fine.
