David Lynch sorry for the delay. No, once you bypass the heater core you won’t have heat. You won’t have radiator fluid leaking from your heater core either.
David Lynch you can buy a heater that plugs into your charging port , it better than smelling antifreeze and gives u time to save for repair or figure out something else.
You’re quite welcome! I don’t really put much effort into this channel, but I found myself in your same position when I made it. I still have the truck with it bypassed and my 16 year old daughter is driving the truck until she saves enough money to help buy her own car.
I’m going to try to flush my core. How in the heck do you reach way back there in the firewall? Looks like I’m going to have to lay down on the engine compartment or something, as the core hose connections are way back there. Did you remove anything to make access easier? Perhaps that “bracket” to the left of the hoses that has the three large electrical harnesses? Any insight on how you we able to reach and work back there is appreciated!!
I definitely had to use a step stool and lay on top of the engine to reach those connections. I don’t remember needing to unhook anything else, but I can see someone with larger hands needing to unmount the connection box to the upper left of the heater core ports. Maybe have a small handed person reach in there to unhook the connections.
My 2007 f150 heater core is slowly getting worse . I think because I used regular tap water when I flushed my system few years ago it sped up the corrosive process
@@willdavis17 hey man I just did the bypass and man I should have done this right when it started!!! Works perfectly! No more antifreeze smell and ac works better! Thanks man!
Correct. If you bypass your heater core, you won’t have heat. That’s the whole point of doing the bypass… If your heater core is leaking, you won’t have heat or any engine coolant fluid eventually. You can either do this bypass and live without heat for a while, or replace your heater core. When you do this bypass, you’re diverting the hot engine coolant away from the heater core and simply recirculating it back into the radiator and the engine.
No. When you do what I describe in the video, you’re simply skipping the heater core. The lines I’m having you adjust connection with keep the flow of coolant circulating around the engine and not passing through the heater core.
@@MIKEC2000 no. You’re disconnecting from the heater core inlet and taking that line and connecting it into the return side of the engine cooling system. You’ll see once you get under the hood.
Sweet christ finally a clear video that puts me in the general neighborhood of what I wanted to see for my own truck.
Thanks for saving my sanity. This short but super helpful video really spoke volumes. Thank you, sir!
Thanks for the video. They quoted me $1000 to replace heater core and in Tucson it's hardly ever winter. Bypass took me about 5mins
Frank Pineda you’re quite welcome. I still have mine bypassed. No issues thus far other than amazing cooling from my A/C.
So by doing this the heat will not work?

I have the '07 5.4L Triton F-150. This will hopefully be exactly what I needed. I have watched so many videos "2003 to 2008" and such. No help.
I know this is an old video but TY ! My heater core went out in 06 F150 and I just did this bypass on it. Saved me some $

Going to have to try this tonight. I live in a small town and just got a quote for 4-5000 for my heater core.
Thank you bro!!!! Saved me a headache and good amount of time! Preciate you!!
Sir thank you...you saved me a lot of time and money. Good video
Abdullah Mu'min, you’re quite welcome, Sir. I’m glad to see this video still helping people. Mine is still bypassed and have no issues.
I’m a pipe fitter so this should be easy😉 🍻. Ty sir
Thank you for the info!
Best by pass for such an expensive fix for a vehicle .
Got a quote of $1660.00 today to replace my heater core (In Florida). Gonna miss the few days without a heater. The defroster, on the other hand...
Thank you!

Hi, my name is Jerry and here is my rig.
My 2007 f150 heater core is slowly getting worse . I think because I used regular tap water when I flushed my system few years ago it sped up the corrosive process
Did you have to unplug anything or take a fuse out to keep the heater off just in case you turn it on by habit?
No. It doesn’t work that way. You can set the temp to high heat and it won’t do anything but blow cool air, especially if the A/C is on.
@@willdavis17 ok cool. Appreciate it. I'm going through the same thing right now and didn't wanna burn anything up if it was the case. Thanks man.
@@willdavis17 hey man I just did the bypass and man I should have done this right when it started!!! Works perfectly! No more antifreeze smell and ac works better! Thanks man!
@@keithb1978 so glad to be a help, Keith! I still have the truck and it’s still working fine all these years later.
@@willdavis17 dude mine has 689k miles on it lol. I want to hit 1m before I lay it to bed lmao! Thanks again
Hey man.. tried the bypass but if it doesn’t run through the core it will not have heat? Nothing will be connected to the core hoses right?

Deff helped man thanks
I don’t understand how connecting it to the outlet , won’t it go back in through the heater core in reverse?
No. When you do what I describe in the video, you’re simply skipping the heater core. The lines I’m having you adjust connection with keep the flow of coolant circulating around the engine and not passing through the heater core.
@@willdavis17 but you’re plugging it into the outlet correct?
@@MIKEC2000 no. You’re disconnecting from the heater core inlet and taking that line and connecting it into the return side of the engine cooling system. You’ll see once you get under the hood.
@@willdavis17 ok thanks!
@@willdavis17 sorry just re watched and I understand. Only thing is for my engine the back bottom is not a quick connection
Hell ya!
Thanks
