Throttle Body Coolant Bypass

I did the mod and i had lost a little coolant. Drove about 10 miles and got a coolant light that instantly went away. I noticed the fan was running loud while at a stop light. I pulled over at the next gas station within a half mile and added coolant as it was low. Coolant temp got to about 233 according to Tourqe. Now at idle I can hear the fan running over my engine and exhaust. It also stays on briefly after turning the car off. The mod went well with no problems besides loosing some coolant. My IATs are much let now so it seems that the mod worked. All coolant lines seem to be hooked up correctly. Had anyone else run into an issue like this? Any ideas?

Burp the system and add more coolant.

I added more coolant and let it sit for about 20 minutes. Turned off and on a few times. No fan. Drove a few miles home and parked it. No fan. I think it's good now. She was just thirsty.

Okay....in preparation to do this, is everyone getting 6" of fuel line and two 1/2" x 1/2" brass couplers or just one 90° brass union fitting?

I did it with one 1/2" x 1/2" brass coupler. I connected it to the left TB hose and the longer hose on the right I actually cut a bit shorter to make the run with no kinks.

honestly if you are somewhat mechanically inclined and have a little time, draining the coolant, taking the throttle body and intake manifold off isnt too hard and you can bypass both the throttle body and intake manifold ports and get even better results!

heres a quick torque screen shot from this morning. speed was about 60mph


also... i have the stock cold and hot pipes... cold pipe should be on the way from X soon and i am part of batch #3 for the new hot pipe

That looks great, do you have the logs of that run? I'd love to see it.

sorry no logs... honestly in the year i've owned the torque app thats the 3rd time ive used it... the first 2 times were to clear a CEL on my car and then a 2nd time to clear a CEL on a friends car after we fixed an oil pressure sender.

it took me 10mins to figure how to change it from C* to F* lol...

my dash said 70* out this morning so im assuming the torque app is hitting really close to actual... i want to add RPM and speed to this screen so when i screen shot it'll have more data if people have questions...

also right after that screen shot, i went to 65mph and it dropped to 87degrees...

now that i actual know somewhat how to use this app ill probably try a few things... maybe wrap my intake pipe and see if that makes a difference...

makes me wonder if getting some of that gold reflective tape and then taking the intake manifold off and putting the gold reflective tape on the underside of the intake manifold would help shield heat from the block... and it would still be steathy

This thread should help figuring out torque app.

So if I'm reading this thread correctly, all I need to do is buy one of these and two clamps, then burp the system?

Don't we also need fuel hose?

Oh i just saw that post. Looks like you're right.

if you want to just do a quick bypass of the throttle body, all you need is the elbow and clamps.

with what i've been talking about is i went a step further and removed the intake manifold and removed the coolant hoses that are connected to the back of the intake manifold and i put in a new hose from the oil cooler to the water neck to bypass both the throttle body and the intake manifold

still playing around with torque and such here... i went to data log my drive to pick up my daughter to show temps, speed and coolant temp but i guess i didnt have data logging setup properly on my phone... so i believe i have it setup correctly now so i will do a log tomorrow on the drive to work to see the difference in temps.

i dont let my car sit idling like a lot of parents do during picking up kids... but my intake temperature highest reading was 154 degrees... coolant temp never went above 188 degrees and after a little bit of driving intake temp dropped to 130's then continued to drop as i got to the faster roads closer to my house... lowest reading i saw was 107.

this was all when the car dash was saying 89/90 and torque was reading ambient temp as low 90's i can only assume torque is using the readings off the temp sensor that the car has and maybe its just reading it a different way... idk... but between 50 and 65mph i was only getting a 16 degree raise in intake temp from ambient. i would say my driving average was between 109 and 113 intake temp after the heat soaked intercooler was cooled off a little

What size hose and what length, did you have to get for the bypass of the intake manifold?
