Throttle body coolant bypass hose

hey everyone i just did the throttle body coolant hose bypass MOD. and here to offer a tip. i went to the auto parts store and got a molded heater hose from them that basicly bolted right in and i didnt have to modify anything!! The part number on the hose was GDY-63069, as for the brand of the hose i have no idea. but thought i would post anyways someone else might get lucky. not to sure if it makes a differance or not but decided to do it anyways. remember that if you drive in cold weather do not do this MOD as the throttle body will ice up and freeze and then it is a world of problems.

Yes this is the MOD posted in the articles section. my car has A/C so the new hose goes from the front of the lower intake to the heater bypass valve.

Re: Throttle body coolant bypass hose

Could you post some pics? I know it sounds stupid to ask for pics of this, but i'm doing this too and want to know where you ran your hoses.

Re: Throttle body coolant bypass hose

it was a local parts store here. if you ask nice maybe they will let you go in the back where they have all the molded hoses hanging on the wall. thats how i found this one, but there is no way to cross reference from the part number to the vehicle it is supposed to fit. see if they can check company's like gates, goodyear, dayco, ect. the prefix GDY almost suggests goodyear? sorry i cant help more but thats all that was on the tag?? but if you do find one and it works the same let us all now for future.

Re: Throttle body coolant bypass hose

It is a Goodyear Hose. I was able to find it online at Autozone. If you go to their website and do a search for 63069 it will pull up the hose. You can order it from there. That hose will work much better than the hose I've got now. Thanks iamiroc

If yours is a Lt1 there's a little more involved in doing it compared to a tpi 3 gen car.

It gives you colder air so you can burn more fuel during combustion.

Touch your tb after a little drive...do the mod...drive it again then touch it again. Colder air is denser than hot air.
