Throttle Body Bypass Mod (05+)
Ok I saw this back on Cub Titan a year and a half ago and have been run this for over a year with no ill effects summer or winter. But the throttle body bypass basically takes out the hot water running though the throttle body. Its a cheep and simple mod with the L fitting and 2 caps it was less then $10.
Parts and tools needed:
Good pair of small pliers
Flat head screwdriver
2x 3/8 in bypass caps (the ones I got came 2 in a box)
3/8 in L or strait fitting
A shop rag.
Optional:
2 small hose clamps.
Gressless lubricant.
Ok make sure the motor is cool (I did it first thing in the morning)
1. put the towel under the throttle body to catch any coolant that might leak out.
2. undo the 2 spring clamps that hold the coolant lines to the throttle body.
3. Pull the coolant lines off the turtle body (I used a flat head screw drive to move them a little and break the seal)
4. Install the L fitting by sliding the hosed over (a little bit of gressless lube helped get the hoses to slid on.
5. Move the spring clamps so they are hold the hoses to the L fitting.
6. Slip on the 2 bypass caps.
7. Turn on and check for leaks.
Total install time was about 15 mins because I needed to go back inside a for the screw drive (so should take you about 10mins to do)
Gains:
I know there was some debate on this here about the gains you'll get out of this mod. Yesterday the truck had air intake temperature of about 86-90 degrees in 70 degree out side air temp, today the truck was about 71 degrees with 66 outside air temp. Both were done at 40 MPH. Also something I was not expecting the water temp dropped form 195 degrees to about 188-190. No real butt dyno increases though.
Note: Intake air temp taking with Scangauge 2 over a 2 mile stretch of road. Truck has Volant CAI and Magnaflow exhaust.

You can see the 2 coolants lines in the throttle body

Now with the caps and the L fitting
