Ok.. it is almost summer. No more cold weather. Time to do some free mods to help the car
stay cooler this summer. How about re-route the coolant lines to bypass the throttle
body, and IAC then make a block plate for the throttle body to eliminate irratic idle!
Tools:
10mm socket
12mm socket
flat tip screw driver
tin snips
drill w/ 15/64"s drill bit
needle nose plyers
Materials:
sheet metal
RTV hi temp silicone
3 small 10mm bolts
Time and Difficulty:
30-60 minutes / if you can remember and work a wrench, you're set!
Before you start:
Make sure the car is cool. Ther will be some coolant that leaks, and if the car is hot, you
could get burned. I'm adventerous, so i like to play with hot coolant!
Step 1
Remove the radiator cap to relieve pressure in the coolant system. Take off the coolant line
that is the farthest back, that is on top of the rear waterneck. Some coolant will spill from
this line, so be careful.

Step 2
Now remove the remaining coolant line that runs from the front port to the throttle body, from
under the throttle body. Now plug the end that was in the throttle body, into the rear port that
you removed the line from in step 1. Bascially, you are routing the coolant in a circle. You
can also remove the lines that are no longer in use from the IAC(on front side of intake manifold)
It is sometimes easier to remove the IAC to get the lines off unless you have a nice set of
angled plyers.

Step 3
Remove the intake from the throttle body. Remove the TPS harness(rear of throttle body), the
MAP sensor harness(on top of throttle body), and the vacume line.
