Hey guys i have a quick question, M throttle body is pretty dirty on the inside and out and i was wondering if i took off all the sensors and put it in a container of boiling water and some soap or something if that would hurt it at all. Does this sound like a bad idea or would it be ok to do. The carbon and grease is pretty built up on it and i figured this would help get it off alot easier then scrubbing it for an hour.

 

I am curious about this. I took my elbow off the other day and noticed all this brown build up around the openings.

 

yeah its carbon build up, thats what im trying to get off but its so caked on there. Theres also alot of crap on the outside to. I dont see how boiling it would hurt it cause they do it the the intakes and heads to clean them, why not the throttle body if you just take the sensors off

 

Use CRC throttle body cleaner that is safe for fuel injected cars. There is actually a picture of an L98/LT1 style TB on the front. It will protect the coating on the TB blades and clean it well.

 

all the sensors come off of the TB very easily. Just take them off, and get a new gasket for the bottom portion.

 

Well i have the tb coolant passage bypassed so thats no problem, i just wanted to make sure boiling the throttle body itself wouldnt hurt anything before i did.

 

Why not just follow my suggestion above, it's safe and it works.

 

because.....they like to do it the hard way

 

Boiling water will not necessarily removed caked on carbon.... it's not water soluble. They make "throttle body cleaner" specifically to remove the kinds of materials that build up in throttle bodies. Why "boil" the shaft bearings in hot water and detergent? How will that heat affect the temper of the return spring? Will it leave water in the threads of the throttle stop screw, causing it to rust? Will the boiling water and detergent remove the anti-coking coating on the blades?

You'll need the "kit" for the top and bottom plate gaskets. Be carefull not to destroy the seal for the TPS sensor. When cleaning the pintle on the IAC motor, do not apply any force or try and move it.

 

I would listen to javier97z28 if I was you. The throttle bodies have a coating on the the throttle shaft to prevent wear that can later cause vaccum leaks. There are special cleaners that he is suggesting that prevent the coating from coming off during cleaning. I know the new throttle bodies on GM cars and trucks have this coating and there is info on GM's website regarding proper cleaners.

 

Leave the Tb alone if its not sticking. if you are concerned with carbon build up seafoam the engine and be done with it. Just remember to change your oil after cause it does tend to thin it out a bit.
