Throttle Body Heater Hose Leak - Need Size?

[Zap]

I know I've replaced this on one of the cars before - can anyone tell me what size coolant hose is used on the throttle body?

This is the one that goes up from beneath into the TB and it looks like it bends down and into the engine...

It appears to be 1/2" or less but I want to be sure before coolant is shooting everywhere....

Thanks!

The throttle body hoses are 3/8".

Thanks for the info! I'll have to go pick one up so I can stop the coolant from spraying everywhere... yuck.

I'm just lucky I've got access to a maintenance garage with a heater, otherwise the -4 temp would be just unbearable.

I would and have just bypassed the TB and IAC heater hose connections. Just loop it back to the block.
