plugging up the TB coolant hole

[My3birds]

I have heard of people plugging up the coolant hole in the bottom of the throttle body. The product they used was something like water weld, or cold weld. Is this stuff basically glue? What would work, so it could withstand the hot temperatures of the coolant, and still stay hard and not decay from the water?
Thanks,

anybody know about this?

You can remove the TB and put anything you like in there to plug up the coolant passage. Just make sure it won't break apart while being submerged in coolant. I don't know if I'd put a plastic cement in there. It's kinda ir-reversible when it's done.
Again, you should go with making your own gasket and just don't cut out the coolant passage. Put a thin layer of silicone over that area so it won't soak into the gasket and break it down.

if i remember correctly, you can make a throttle body spacer out of a material called delrin. now, do you have to re direct the coolant so it can flow in one hole and out the other, or is it okay just to block the two holes altogher? Also where can i obtain some delrin at an affordable price?

You can just cut a slight groove in the spacer on the coolant side to allow it to flow.
Also, I looked delrin up on ebay, and... http://search.ebay.com/delrin_W0QQso...ectZ1QQfromZR8

I just used gasket maker on mine. we filled the entire grove on the throttle body and then we also filled the groves on the ntake side were all the collant comes from. And so far it runs so much cooler.

For all of you guys that live up north-

That coolant passage is there for a reason. WHen it is cold and humid in the winter, GM found that thier throttles were icing over. THis allowed less total airflow thought the throttle, and kept the throttle from closing properly.

If you want to plug your throttle coolant passage, do it in the summer, and use a temporary material.
