DIY: Throttle Body coolant by-pass...

[healtoc]

Bummer about the prob..didnt see ur post either. ok. ecu reset might help. What may have happend is A the tube is no good becuase there is going to be extra pressure or B the shorter tube is sending too much coolant through. Keep in mind that there is much longer path of travel that it has to go through when it is still in stock format. u said that u are at the right coolant level...mmm

Funny, after I did this mod, my battery failed the next day.

Total coincidence, right? Car has been running fine for the past week.

Waiting to hear how this turns out.

I bypassed the throttle body coolant lines by capping the connections and did not have any problems. Now, the connections are no longer capped as I am using the fittings to feed coolant to the turbo (TB coolant lines still capped of course).

Why can I no longer edit my post for a typographical error?

Ok... excuse me for my stupidity. My car is running fine now. I looked under the hood again and guess what? I've checked all the fluids, sensors, hoses to make sure everything is topped off, connected, and tightened. However stupid me forgot to tighten one of the clamps on the cold air intake when I was reinstalling it. The clamp was loose and it came off.

After tigtening it, the car starts and runs like a champ! I overreacted and Sorry guys!

BTW I like to say one thing about this mod. I drove to work from home (23 miles) in 59F to 60F weather condition. When I got to work the T/B is still cold. Then later on tonight I drove home from my buddy's house (approx 30 miles) in 55F weather condition. I drove it hard a couple of times on the freeway and the T/B is still cold when I got home!

Yeah, I noticed this too. Additionally, if you allow the car to warm up while sitting still, you'll notice that the manifold, throttle body, and intake all get hot very quickly. Once you get some air flow through the engine bay, it cools the entire system down quite a bit.

I'm thinking harder about the IMG. I wonder if there is any type of wrap that you can use for the intake manifold and CAI (or maybe stick a little thermoelectric cooling pad down on the lower part of the intake )

I'm only on my first tank, but I have noticed a drop in gas mileage . . . 27 mpg to 23, but this tank was mostly city, and I usually only bother to calculate on long trips. I'll keep an eye on it.

can I get a better pick of wear to bypass it to.. (near the tranny) I cant really make out where that is...

[healtoc]

Man you were really scaring me there...was worried that i was going to have a big prob. Good to go i guess. mix that with a throttle body gaskit, composite rail and manifold and then get a race car style intake and this thing will make some serious power...for a intake set up.

I took some pictures of my DIY. Hope the pictures and description helps.

So basically you bypass the coolant from the top of the engine to the black coolant pipe (see picture 1). Don't forget to flush out the coolant from the T/B. At last, you cap off the 2 openings on the bottom of the T/B with 5/16'' vacuum caps and clamp them tight just in case (see picture 2).

I don't seem to have that problem. Mine stays COOL even when I let it idle for a loonnnnnnnng time! Thanks to the TB bypass mod and the P2R TB gasket mod.

And now for sumtin random.

Wake up Gomer! Your 15 year old Mustangs are dinosaurs compared to the Civic. You'd be surprised at the technological advances of the past 15 years. But I suppose everyone on this forum is smarter than the best that Honda has to offer, so please, proceed with this very useful mod.

Im gonna do the p2r tb gasket tomorrow. Looks like I might be getting some 5/16 cover for the hoses too! Good thing I found out which size they are!

[taejinah]

i'm going to be doing the bypass and img sometime in the next day or two. just wanna know how exactly to "flush" the throttle body of the coolant and if i need to disconnect battery and let idle after or anything. thanks

[Zeuceone]

no need to disconnect the battery. to fluch it just pour some water down one of the hoses that runs in to the throttle body.

Just water eh? After I flush it, do I need to let it sit and dry or anything? I guess it's ok to have a little water left inside the throttle body (no rusting)?

[Zeuceone]

yeah just water. water runs thru it as it is. it will evaporate with the heat of the engine.

subscribed for future use.

[SiViC06]

Yeah im gonna try this when I get my gasket

Nice Job
