throttle body heater hose

[1979lee]

Well its time to remove and clean my throttle body on my 98 3.1 lumina(174k miles and never properly cleaned),

who sells the little tb heater hoses?

i went to a u t o zone, and they didnt sell them.

 

anything i need to know about cleaning this tb?

looks like a simple job, and ive been working on cars my whole life.

 

thanks:thumbsup:

Just get some heater hose and make 2 of them yourself, with hose clamps. There's nothing special about it.

it looks to be 3/8 hose i think... one is 2 inches long

the other is about the same but curved.

bypass it...it will help keep IATs down and will not effect tb icing up, unless in extreme cold (artic)

i would bypass both hoses. by jumping them to each other. reason is more power, you wont be heating up the throttle body so this means colder fuel so more power. good luck.

dont bypass it if your in a cold climate been there done that

Its 13* out this morning and no issues with mine being bypassed:thumbsup:

thats shorts and tank top weather here when it was in the -10's for 2 weeks straight had some major issues

Bypassing it gains you 0.01 hp and 0.001 torque. Not worth the risk of a frozen throttle body to bypass. The coolant runs through the throttle body for a reason, it wasn't put there to reduce power and increase costs.

 

Some scrap heater hose at the part store will do the trick for new hoses.

yes sir i agree

Except 99.99% of all newer cars dont have coolant running through their throttle bodies:thumbsup:

 

Engineers figured it out a while back that you dont need to do that.

 

What are yall doing to freeze your TBs? Quit putting water in your throttle body and youll be fine:lol:

agreed, if he is buying hose and repairing the hose, why not just bypass it?

[RobertISaar]

well, no 95 and prior 3100 ever had it, and i've heard of exactly 0 cases where there was throttle stickage...

[white4d96]

IIRC Milzy sells a coolant tube with the barbs for the TB tubes deleted. I seem to recall it being pricey though, like $40?

[Galaxie500XL]

This used to be a real problem with carbeurated cars, mostly because there was FUEL being pulled down by the throttle plates, along with air. The '64 Ford I had was bad to do this if the temps were low, and humidity was high.

 

I can't imagine that with port fuel injection, meaning the throttle plates are DRY, that this would cause any further issue.

Well folks, ive done the work on the lumi, all fixed up now, the egr and tb were in need of cleaning for sure. the egr passage had some black crap in it, i cleaned that out with a piece of firm wire. and carb cleaner and compressed air gun the tb hoses were reinstalled with new hose and clamps, the coolant passage was slightly plugged with dexcool sludge, but all in all it was an easy fix.

it idles smoother now.
