TB Coolant Bypass

[spf_lexus]

Just curious guys but I have mine bypassed and my car takes forever to warm up. Wasn't an issue here in CA but now i'm in a 5000ft elevation that gets down to 0 degrees at night. I also keep getting a TRAC light on my dash but once the car has been driven for an hour it goes away all day until I let it get cold over night in these Colorado winters. Should I be re-attaching mine?

Get the hair dryer to heat the TB up. LOL. Try to hook it back and see what happens. It won't take over 30 minutes.

Hey thats not a bad idea. I might give it a try... I'll heat the TB for 20min and then start it up for a few... we'll see!

why are you lopping the lines, its so much cleaner to cap them or better yet pull out the metal nipple and press in a plug. I have mine removed as well as do i have everything removed from my motor thats not required to go.


edit: haha i just knoticed 5 year thread revival!

I could care less about the 1% hp increase... I was just too sick of messing with the lines every time I work on my car. I admit it's probably not too smart at these cold temps so I will reattach them.


Yeah quite the old one! Figure these have to be revived from time to time for noobs like me

normally that is there to keep the butterfly from freezing open in cold conditions. i had it happen on my lawn mower. different engine but same theory.

^^ correct.
Same reason as why they heat the ISCV as well, it can also freeze up.

I removed the lines from both the TB and ISCV while cleaning up my 1UZ.
I also used a die-grinder to remove the passage ways from the TB and ISCV, so they look clean.
Here in South Australia, there is little chance of them freezing up

See I just came from my land of warm weather, ah! Now it deals with zero degree weather at nights so mornings arn't much better.
