So my car developed a coolant leak, a small one luckily :). The throttle body housing's warmer unit's gasket had failed... While squeezing one of the radiator hoses I heard air, and some coolant, rushing out of a hole in the gasket. I know it is a popular mod to bypass this heater, so I opted to do that rather than fix it properly. This job took me a whole 5 minutes!
The leak can be seen here:
So the part needed, called a "hose splice", can be found at Lowes or another hardware store.The size you need is 3/8". Lowes is within 3 miles of my house so I usually just go there. Locally it was $2.52
Tools are pretty simple: a 1/4" nutdriver, a small flathead screwdriver, and a pair of hose cutters.
Here is a closeup of the hose splice
Step 1: Remove your ICV. Just wiggle the hose off the throttle body, then the other end off the intake boot. This job takes 5 minutes, so just set it on your intake manifold.
Step 2: Then loosen the top hose clamp with the nutdriver. Screwdrivers work too, but nutdrivers wont fall off the clamp, and will not strip it.
Step 3: Using the small flathead screwdriver, pry the old hose off (or just yank on it). Coolant may come out, but it is not a big deal.
Step 4: Do the same with the bottom hose
You dont want to lose your hose clamps, so take them off and put them aside. I chose the fuse box cover
At this point, both lines should be off...
Now is the hard part. Look at the lines and imagine where you could put the splice in. This is hard to photograph, but is very straight forward.
Step 5: With an idea of where you can put the splice, cut off the excess hose.
Step 6: Slide on the hose clamps (make sure they both are facing the same way!) and fit the splice. Push each hose fully onto the splice. Tighten the hose clamps!
You're done!!!
Here is a final shot of the bypass:
