Throttle body coolant hoses
2003 Impala base.
Are those 3/8" inside diameter? I'm thinking to just get some straight hose and replace them; one is bulging a bit. Or, could I eliminate them and bypass the TB. I'm in middle GA where it doesn't get very cold and the car is garaged. Thanks!
Update: should be 9mm. 3/8" should be close enough. I'll know for sure this weekend when I finally take them off.
