LS1 throttle body by-pass 02 WS6
I am a retired jet engine tech, but when it comes to my TA Ls1tech is my "go to guys".
Regarding TB by-pass mod. I have seen here were the TB has been taken out of the coolant loop by running the long hose. There is even a "kit" on Ebay for $35.00 to do this also. WHY??
My question to the board is: Why not cap the coolant T-line at the engine. Cap the other end at the radiator neck. Then cap both fittings on the TB.
Total parts: 4 hose caps/plugs and clamps.
Recap: Coolant blocked at engine and radiator.
TB fittings caped to seal off the air.
Any one have a problem with this way of doing it??
Thanks guys

I've always been taught, by reading here, you do NOT want to block off the steam tubes. I simply bought 3/8" heater hose and 2 1/4" worm clamps and had problem solved. Right around three bucks, if I remember correctly.
I didn't plug the tubes on the TB right away, b/c I wanted all that liquid gone, evaporated, and dry. They've since been plugged though.

Steam? Thanks for the input.
The use of the term "steam" has me confused.
H2O when heated in a closed system expands, and in this case pressurers over into the overflow tank. Doesn't make a vapor. It should be hot water that is flowing thru the TB. Not stream. Cap the lines to TB. No hot water to heat it. Coolant flows to all over areas as it should.
But Im heeding the advise, and going the by-pass hose route.

the steam tubes are an H shaped pipe that runs underneath your intake.....if you look underneath the front of your intake you will see a little metal tube that leads to a square right next to each head....they get steam pockets out of the block, and really have nothing to do with the tb.
