I live in ga is it necessary to do a Throttle body bypass , i heard it keeps the TB from iceing up in the winter,it dont get as cold here as up north,thoughts?? thanks
Absolutely,do it. They're all the same. After draining some coolant,remove the elbow from the steam pipe to the throttle body. Disconnect the line to the throttle body from the coolant reservoir,at the throttle body. Connect the line to the steam pipe,after trimming for length. It''s that easy.
i did mine on my 95 9c1 yesterday u dont have to cut the line from the reservoir just push the line on the steam pipe all the way ill put a pic in a lil
You got it backwards... the throttle body set up as it is (stock) keeps it from freezing up. You will never have a chance for it to freeze in GA so, yes, DO IT!
I live in Pittsburgh and never worried about it and as someone else said... I've never heard of someone icing up their tb.
You should definitely do the TB bypass. I did it to my 95 Z28, 96 Impala and 04 Denali XL. Never had any problems and the temp dips into the mid 30's during the winter.
I forgot to mention that you might want to drain some of the coolant out or put a lot of rags around the optispark because when you take the hose off from the TB inlet a good amount of coolant will leak out.
pics are from the passenger side so u can see were to put hose
ok best way to do it is have your car cold mine was hot and still coolant dident relay come out but do it when cold if you pulled off the tb it would be easier and the gasket is only like 2.99 at auto zone but pull hose off tb and at auto zone they sell vacuum caps for like 3$ the site shows there more but go in and ask then best is to use a razor cutter to cut hose off steam pipe cause mine wouldn't come off then put the hose on it fast so it wont leak then plug other hole with cap and your done let
and i didn't cut my hose just push it all the way on the pipe
dont worry about it i wish i had these pics when i was searching how to do it even with all the diagrams on google i still dident get it lol it realy is easyer with the tb off though its only 4 bolts just dont do what i did and was cleaning my intake with carb cleaner and the red plastic tube flew in there lol
A freezing TB has NOTHING to do with outside air temperatures. It has to do with the pressure drop across the TB, and how much humidity is in the air. So being in a hot humid climate makes the problem more likely to happen.
During a pressure drop, the humidity drops out of the air, and will freeze over. How much of a pressure drop happens across your TB.. depend on throttle position.
This used to be called "carburetor icing",and is obviously temperature related. That's why the problem was more common in colder climates. Actually,it was potentially very serious with aircraft (back when they had carburetors) much like "wing-icing". I have not heard of any examples with these cars,however. Perhaps, because the throttle body is "nested in" more to the motor. Rather than stuck on top (like a carburetor) away from the warming effects of the radiator,etc...
its same principle of refrigeration, as we do not have carbs I didnt think it germane to throttle bodies.
liquid under pressure introduced to low pressure atmosphere will flash and evaporate causing a temperature drop.
as our throttle body blades have nothing to do with liquids gasoline or otherwise, it wont happen.
and again, nobody Ive heard of in 9 years on this board has reported their throttle blades iced up on them.
How would they even know their blades iced up???
Even in the 1980's, GM had heater plates beneath the carbs.
I was once blowing down my 80 gallon air compressor. The air was coming out of a 3/4" ball valve, and aiming at a piece of wood. A layer of ice formed on the wood, and it was 90 degree's outside, in the middle of August. By the time the compressor was out of air, the ice was 1/4" thick.
The closest I ever got to the throttle blades sticking open was in a civi 4.3'd 94 on its way to the JY. The blow-by was so bad, it sent enough oily crud over time up to the tb via the pcv vent to cause the throttle to stick open a little.
It's like a choke. If its cold outside the coolant warms it up. If its warm already then it doesn't really matter. It's more of a preference more than performance. I did it so I can change the throttle valve easier.
Don't be skeerd. People in Minnesota,and North Dakota have bypassed theirs. One side benefit is much easier removal of the throttle body either for cleaning/inspecting,or to make it easier to get to something else. It also doesn't cost anything (I like that)
Who says that ???????????????????????? you??? cwm8
Get involved with aviation, and you will see icing occurs at all temperatures. There are certain temperature ranges that it is more prevalant. And it is well charted in the aviation industry.
