Southern Raised and Respectful: Nice Job! I had same problem and performed this fix this afternoon. Coolant hose was really rotted as you showed in video. Only problem now, is electric cooling fan runs when coolant warms up. I'll pull and check thermostat tomorrow, since it could be a problem since my leak was there for q good while. Thanks for a great video and fix!!~
Jason M. Townsend: Wow this is a Great Video. I have a 99 F150 5.4. This dam transfer tube just popped on mine. The only difference is mine is a Metal Pipe. I'm hoping I can figure something out the way you did. It may not work on mine since Mine is Metal, if not I'll be removing the Intake for the 1st time. I fix a lot of things on my vehicles but I've never taken on a job like this before. One of the Best things I learned from this video is The Grounding! I've been having Big BIG Problems with the Antifreeze in my Truck Rusting up so Fast. I've Flushed it, & Flushed Over & Over & it continues to Rust, so much so this Pipe Rusted through & Busted. I'm getting a New Ground Cable ASAP, I Never would of thought about Electrolysis. Thanks SO Much for the Video!!!!
kennedy Stewart: I got steam coming from under my intake is this where it's coming from.
Steve Campopiano: what year make model is this? i need that style bypass hose and mine is hard line.
Steve Campopiano: Hello. i am about to replace the leaking intake but would like to remove that horrid factory hard line and use your setup. Heater core is already bypassed and i keep it simple on my personal daily cars.... Anyway. I have a hard tube and the engine shown has a barbed nipple setup. I cant clamp that hose around it and be sure it wont leak. Any idea what model i should use when i hit the dealer to look for this outlet piece?
psychotogen1: Thanks for the heat shield idea. I'll be using that trick later on. Nice job here
Manny Lumbres: Thanks a million. Just finished doing this. Saves a butt load of time n money.
InTheFleshInc: Hi, I discovered a leak on that manifold cross over at the part where heater core hose goes up and back. It appears to be at the connection where that manifold bolts down. Is that a common problem and is that exactly what you are working on here?
Dan Southern: FYI.....the inlet and outlet on the heater core is 3/4 in. and the pipe to water pump is 5/8 in. that's why you need the 3/4 x 5/8 hose connector off the core.
Henry Sanjurjo: Can I ask you where the other heater hose travels? Is there another pipe that the other heater hose connects to that could be rotted or is it definitely the pipe under the intake? Im guessing the other hose connects directly to the intake manifold
Henry Sanjurjo: I'm pretty sure neither of those hoses disappear. They both clamp onto to some nipples on top.
Henry Sanjurjo: Does it connect into the bottom of the intake manifold? I believe my heater core hoses clamp on to some couplings somewhere near the top of the engine. I don't remember seeing them routed down along the firewall anywhere. Wondering if it's one single pipeline through there
Henry Sanjurjo: Ok. Thank you. I definitely saw a rubber hose with a clamp at the water pump connection. I'm wondering where the pipe travels as it heads to the back of the engine toward the firewall
Henry Sanjurjo: Great video man. Do u know if this repair will work for a 1992 grand marquis.? My mechanic says the pipe under the manifold is rotted out and coolant leaks right out. Looking for a quick fix.
Chucky G: Ok I did the bypass repair new t.stat bled the coolant but still overheating...looks like no coolant flow...water pump possibly?
