ok is it ok to cap off the lines coming from the front of the block, going to the back of the block. the ones that go through the throttle body? or do i have to run a hose inbetween them? I did the throttle bod mod and am trying to figure out if coolant has to go through there.

Thanks

 

I'm pretty sure the only ones neccesary are the two main radiator hoses.... but I'm not 100% sure.

 

Yes, you can cap them.

 

thank you

 

Don't JUST cap them -- they tend to leak, or become brittle and crack. Mix some JB weld, and shoot it down the nipples...(of course, let it dry completely before filling the coolant)...then put some RTV inside the cap, put cap on, and put a small clamp on the cap.

 

By "cap" I was referring to plugging them.

I wouldn't do what you suggest either since it's really hard to get a JB-Weld to bond if there is any contamination, and it's nearly impossible to remove the contamination without putting the whole mess into a parts washer.

If you want a permanent plug, drill out the holes and tap for 1/4" NPT. Then install a pipe plug. That also leaves you the option to reuse the hole in the future...Wish I had done this on my engine...

 

ugh...too late......I already did the JB weld. seems to be rock solid this afternoon when i went to check on it though so IDK. if this doesnt work ill do what u say aaron

 

Ah, didn't know that Aaron :X Sorry! I might do the plugging on mine...

 

Thread and plug is the best option. I have gad both capped and JB welded mine and the caps became brittle and broke, and the jb weld eventually sprung a leak as well. As much as one might disagree with me, I have threaded them while still in the engine bay. I dipped the tap into heavy grease while tapping to get most of the shavings not to fall into the coolant passage.

*I do not recommend anyone try this* It was just how I did it.

 

No problem drilling and tapping them in the engine bay, aside from the awkward factor of having to work with the firewall in the way...

 

so metal shavings in the coolant passage is ok? wtf lol

 

Yes, it's perfectly fine.

They are harmless and will drain out the next time the coolant is flushed.

 

hmm....learn something new every day
