I could be wrong but that is the only small coolant pipe I am aware of. I removed it and looped the coolant that is meant for the throttle body so that no coolant goes to it anymore. Makes for easy intake removal too. The coolant is only needed if you drive in the winter Smaht. I should do that, since mine is Spring through Autumn only as well. I suppose that it's going to be super hard to do with the IM in place tho right? Link to comment Share on other sites More sharing options...
Tehnation Posted June 12, 2023 Share Posted June 12, 2023 Your right. That's the line for the throttle body, which bolts to the top of the driver side bellhousing or back section of the block. It goes from there to the line at the top of the tb. I didn't know bypassing that was a thing. So it's only to heat the air up during winter time or what? Cause I never understood how running hot ass coolant through the tb makes any sense. 1 Link to comment Share on other sites More sharing options...
jaylew Posted June 12, 2023 Share Posted June 12, 2023 the only difficult part is removing the TB if you want to loop off that but honestly not needed. Just remove the charge air cooler and you should have all the access needed Yeah it helps drive-ability in the winter. I have it bypassed for 3 years now and no issue, even in the random couple days of 30-40 degree (freedom units) weather in the spring or fall Wagon is LIFE! - 265,000 miles and climbing Unofficial Build (Restoration) Thread Steering Rack Rebuild Link to comment Share on other sites More sharing options...
m sprank Posted June 12, 2023 Share Posted June 12, 2023 You heat the TB in winter to stop the butterfly plate from sticking. Obviously it needs to be a cold weather climate. If you dont drive in COLD bypass it as you are heating your throttle body and intake air. 2 Link to comment Share on other sites More sharing options...
Enlight Posted June 12, 2023 Share Posted June 12, 2023 You were right @jaylew and @Tehnation, it's the coolant pipe that goes from the block into the throttle body. Making good progress, just need to connect the vacuum lines now and I'll be done with the nitty gritty dexterous stuff. Rain is coming in at 5pm and ending at midnight. I might be forced to come in to rest during those hours before resuming in the wee hours. Might make sense just to clamp it during the summer months. 1 muFreight.co A JDM Container Sharing Service from Japan to NYC Website | Instagram | Email Bessie II's Thread Link to comment Share on other sites More sharing options...

BoozeRS05 Posted June 12, 2023 Share Posted June 12, 2023 After all these years this is the first time I’ve ever heard about a TB coolant bypass. Love it. Is there a thread link with the details?

Lol! lol, sorry to bust your bubble...i tend to jump between the terms. It is hypocritical me, because I can be a stickler for proper technical terms being used to avoid confusion. And @BoozeRS05 No real write up that I am aware of. Fairly straight forward. If you brought your car I'd say we could do it at the ECM hahaha. But really, its just reusing one of the hoses already in that line, and looping it from the coolant crossover pipe on top of the short block, with a barb that pokes out of the top of the block. not the worst thing to get at while engine is in car 1 Wagon is LIFE! - 265,000 miles and climbing Unofficial Build (Restoration) Thread Steering Rack Rebuild Link to comment Share on other sites More sharing options...

It is hypocritical me, because I can be a stickler for proper technical terms being used to avoid confusion. Eh, I get it. Depends on the forum and people you're talking with. In applications where it's actually common to have a super turbo, it gets important. I use both, depending on the conversation as well. I wish there was some way to squish a real intercooler into our engines bays, or wheverever, but what a nightmare of plumbing that would be. The vacuum lines alone would give me nightmares.

m sprank Posted June 12, 2023 Share Posted June 12, 2023 Ok, lets get technical... In the automotive industry charge air cooler, intercooler, aftercooler, diesel intercooler, etc all refer to the same thing. The terms are interchangeable. In the world of compressed air they are referred to as intercoolers and aftercoolers. If you WANT to get scientific, charge air cooler is INCORRECT as all of the devices are a HEAT EXCHANGER. My HVAC training. In all reality I was always taught that charge air coolers use a liquid coolant, not air to air. The liquid to air transfer makes them generally smaller and more efficient. It never bothered me what anyone called them. Link to comment Share on other sites More sharing options...
KZJonny Posted June 12, 2023 Author Share Posted June 12, 2023 I take it back. I wish there was a way to squish an inter super-turbo charge air heat exchanger into our engine bays. Still a nightmare, and ridiculous in any event. Just having fun. My uncle was big into aircraft stuff as well as cars, so I learned a lot from him. Charge air cooler and intercooler were things that would come up when banter got to the technical side. At least to me, the names always made more sense although I guess you could argue our air to air heate exchangers are inter the turbo and engine... Ima go ahead and reroute/loop off that heater line when I have a chance tho. Didn't realize our throttle bodies had a warming circuit, although it makes perfect sense thay they do.

m sprank Posted June 12, 2023 Share Posted June 12, 2023 Many cars heat the TB and have for many years. When it gets COLD butterfly plates like to "freeze". They either stick, or the resistance to the cable/motor is so great it causes damage. Basically ice particles build up and cause an obstruction as the metal is not literally "freezing". The coolant heats the TB and melts the ice obstruction. If it never gets that cold or you are very aware of your car and its condition you dont need it. If you want to make maximum power, bypass it. Do not add extra heat to your intake air. 1 Link to comment Share on other sites More sharing options...
Enlight Posted June 13, 2023 Share Posted June 13, 2023 On a forced break because of the rain, it should let up at 1am. Amazon came today and delivered my injector pigtails, I just had to Dremel their "wings" to make them snap in. Fuel hoses are, except the EVAP line, are all connected. I can't figure it out and I might leave it to the tuner to fix it for me. I hate to be "one of those" customers but here I am. Went to Uhaul an hour before they closed to pick up the trailer. I was able to back up to the hitch on my first try. Backing up my narrow incline driveway was more difficult. Does anyone know where this mystery connector goes? I'm usually anti-OTC's, but I'm very thankful for Aleve these last four days. 5 muFreight.co A JDM Container Sharing Service from Japan to NYC Website | Instagram | Email Bessie II's Thread Link to comment Share on other sites More sharing options...

m sprank Posted June 13, 2023 Share Posted June 13, 2023 (edited) Frustration is working on your machine while the PA is announcing your class starting gate. After spending all night working by the light of a campfire after your batteries died on your lamps. I was drilling out my swing arm to re-secure my rear axle bearing carrier with an Ex-World Champ standing over me shaking his head. The PA was announcing my class starting positions. I went full throttle right through staging past the refs to my gate as it was dropping (in a full 90deg slide to make the turn from staging into my gate). I missed a DNS by milliseconds. 3 laps later I was being dragged off track by medics and sent to the hospital. My last trip to the WB 4 Stroke World Championships. Would do it all again in a heartbeat. Life is brief moments of pure joy intertwined with years of misery. Its those brief moments that keep us going. An old coach used to say "win, pin, or die. Victory, there is no substitute." Oh the THRILL of Victory.... and the agony of defeat. RIP Howard C. Edited June 13, 2023 by m sprank 3 Link to comment Share on other sites More sharing options...
