Bypassing my heater core

[Busted07]

The heater core is not hard to remove at all....just take your time, i have gotten where i can do it within an hour now and the weight you save would be more than you think!

Well, i might try it... i might wait till this next fall to do it.. i just want to get this sucker running for right now, then go back and tweak everything.. thanks for all the help you guys, i appreciate it!

ill check that stuff this weekend. I dont see why i would need to run the bypass hose in the first place... unless its to make sure coolant is flowing through the intake

I would think that you would get enough flow with the bypass plugged.

Im guessing we will find out soon enough lol...

you got it wrong...sort of

water pump bypass hoses DO go to the heater core...
however, one of them goes into the t stat housing.
it flows through the intake, to the passenger side front corner, then into the pipe

then to the core, then the other pipe, and back to the water pump.

something bad will happen if you dont let coolant run through the intake

Superhuaman- he is running a carb intake and doesn't have the tube that runs down the pass side of the intake.

i know that, i was describing a stock setup. but he would still need to have coolant flowing through the intake manifold. unless its not made that way.

But shouldn't the coolant still flow through the intake via the thermostat housing? He will still have the upper radiator hose attached.

i guess so...i dont really know...but isnt it better to hook up those hoses to the intake? instead of looping a hose on the water pump and plugging the intake holes?

I was thinking about this all weekend. I took the housing and stared at it for a while, and now im thinking i need to at least have the bypass hose hooked up...

Reasoning. If i dont have it hooked up, coolant wont flow through the intake until the thermostat opens. with that bypass, it will at least flow the coolant through the intake regardless of what the thermostat is doing. so i think ill just run the bypass hose and block off the otehr hole in the water pump that goes to the heater core.
