Ford F-150 - 1997-2003 :: 2000 5.4L - Top Radiator Hose Comes Off
Sep 5, 2017
I have a 2000 F150 with 5.4 L motor. The last two trips I have had the top radiator hose come off while under heavy load (pulling a long hill) after 5 hours of driving. So far I have flushed the radiator, checked the thermostat, and refilled with G05 Gold and distilled water 60/40 ratio. I do not hear any gurgling in the heater core. Heater seems to work great.
The stock temp gauge shows it right in the middle range between Hot and cold, right before it blows the hose off. I have replaced top and bottom hoses and put new stainless steel clamps at all end except the top, where I am using the OEM clamp that came with the truck. I thought about replacing the top clamp as well but did not want to blow out my radiator, if in fact it is developing high pressure.
Do these clamps get weak with time? Should I use a vacuum attachment on the fill/overflow tank to remove all air before refilling?

Is it difficult to replace the lower radiator hose on a 5.4L? I'm mainly thinking about access to the connection at the water pump.

this winter i have found that my truck's heater core isn't flowing, meaning i have hot on the upper hose and the lower is luke warm and there is no heat while running down the road. I have changed the t-stat and the heater core and radiator are new as of four years ago. last year i could roast a chicken with the heat. i also have no pressure in the radiator hose at all, engine runs at normal temp, no over heat situation and i don't smell any loss of antifreeze.

I blew some hose in my engine and radiator fluid was spraying out of it like crazy. It's on a 1999 f150 4.6 on the passenger side near the rear of the engine but about even with the top of the engine...

I just replaced the engine in my F--150 with one from a van that had only 60K miles on it. It still runs rough and misses. Not as bad as the earlier engine that had dropped a valve. While trying to find the problem, I moved a large vacuum? hose at the rear of the engine maybe 1 inch diameter and it nearly fell off the barb at the back It is also connected at the other end to some type of small metal can. When I pulled on this it fell off and the engine died.
Also need the smaller 5/8 in diameter hose at front of air intake tube. I need a size or a pert number for this hose as I cannot crawl back onto the motor very many times due to a spinal problem. I would like to get this hose and then get under the firewall only one time. I am having issues with this truck, bought is used at auction running rough. Replaced engine with one that was supposed to be a good one, but it runs rough again..
I need to add that New platinum [plugs were installed and the coils were off the old engine that had maybe 50 miles on them and were from NAPA. I only hope htis hose is my problem. However I cannot find any part number or anything on it...

I've noticed a spring of coolant shooting out of a connector that I'm assuming is connected to the bottom radiator hose via a smaller hose. Is there a hose that splits off the bottom radiator hose that is smaller. The leak is not coming from the hose, but the connector it's hooked to. Is this a replaceable part? What is it for?

I own a Honda Crv 2000. I took the car for an oil change at a local oil change shop. They overfilled the oil. I went to the city and came back, and next day the underside of the car was oily and leaky. The car was dripping oil. I immediately siphoned out 300ml of extra oil from the car. After that the leaking stopped and it does not leak/drip anymore. At the same time I saw coolant dripping from the lower radiator hose (where it meets the radiator). I noticed when the fans come on it start dripping. But as of today the coolant dripping has stopped. I am thinking of changing the hose.

I'm going to be replacing my lower radiator hose so figured might as well switch over to the extended life stuff going to probably go with the Delo ELC.. Supposedly it's good for 750k.

98 F150 2wd 5.4 -even though VIN says its "W" 4.6; it has a 5.4 with 4.6 timing setup-found. But that's a whole other story...
So, Replaced heater core. did the blend door too.
A week later it overheated and blew a heater hose off the core at the firewall (several times). Temp was up and down, forced me into cylinder head protect mode, so i called my mechanic.
Mechanic used a sniffer (blue liquid turns yellow) in my overflow tank and there was exhaust gas in it... so we replaced head gaskets, intake, timing, water pump, radiator and the rotted out rad support.
Got it done and back on the road, but a few weeks later and the heater hose quick disconnect blew off again, spewing coolant all over (again). This was what we thought was part of the original problem- head gasket allowing cylinder compression into the coolant passages. the little rubber hose that comes from the back of the intake and goes up into the heater core builds enough pressure to pop the disconnect right off and I dont know why. Like I said- I thought it was the head gasket blowing pressure into it but that's all been replaced. Why the pressure would be so high at that point, and how do I correct this?
This is my daily driver, so for now I've bypassed the heater core, but I'm afraid that pressure is gonna burst a hose and/or fitting again.

I found a leak today on my 2001 Ford F150 Super Crew, 5.4 engine. In the picture, it was leaking to the right of the spark plug, behind the hose. It was bubbling up from the metal. It hasn't been overheating except when I got home and idled with the AC on. What I'm facing?

Just like the title says oil In my rad! Anyway here's what I've seen....I noticed that I've been having to put oil in my truck more often than I need to. I thought maybe I was leaking somewhere but I wasn't. So then I thought I was burning it but no smoke. So then I was reading on this forum and someone mentioned oil in the rad. So I checked and it was pretty black in color so I figure that's what the problem is. My question is would it be a head gasket or intake? I also read a quote from Moto Mel on here that it could be some kind of adapter that is located on the lower left side of the motor that has o rings that can go bad and cause this?The milage on my truck is 145000 and running great (other than this). No overheating or anything.

I did all the flushing, cap, thermostat, 50/50 antifreeze, etc, fixes but when I floor it going up an on ramp on an 85 degree day it will go into limp mode / fail safe mode. Bottom hose?

I went to unscrew the radiator drain plug but the head broke right off leaving the rest of it inside.
I drilled out a little bit of it so I could drain the coolant and bough a replacement plug but there are still pieces stuck inside and I cant get them out.
Should I just drill out the remaining pieces or is there a better way to get them out?

So about 2 yes ago I had a cracked intake manifold and had it replaced..shortly after had low egr flow codes that had me replace every sensor involved on top and three that ford found for me. And fixed...my 01 f150 5.4 super crew has been my best friend last 165k of its 246. So it has a small leak in radiator. Didn't think that would do anything for a bit. Well after almost overheating a few times I pulled up to a job and water was pouring out the top back passenger side....blah blah blah saving 1400 this time I pulled everything to the head. Took off intake put back together torqued to 20lbs.
Still mix fires at low idle and low rpms.gets worse longer I sit at light have redone plugs switched coil pack at the misfire location..still missing. the round black sensor before the egr out of the intake has good vac in but limited to egr. Don't think this is right...has lean codes both banks....but I also had a PVC not in and the exhaust outflow sensor had a hose knocked off again...misfiring...checking hoses nothing obvious... Perhaps the spare coil is no good now....keep one two handy for wet locations... Did I not do intake right...and I did use rtv

So the story goes like this, my teacher was trying to scrap a truck that he had sitting on his farm so i got it. I've been using it for a DD for the past year and a half and not I'm starting to do rust repair starting with rocker panels. But, what i was really wondering is how involved would it be to replace the radiator core support? Main reason being last time i was under the hood replacing the pass side valve cover gasket i hit it and knocked a hole right through it so yeah I'm thinking is about time to replace it.

2001 F250- V10... Lower radiator hose has coolant leaking - Right now I cannot tell if its the hose or the radiator itself (hoping not) - I tried to take the clamp off and it broke - Any tricks to removing the hose? its on there pretty tight.... I guess if I don't want to save the hose I can rip it off with a pair of pliers but before I do that wasn't sure.

After chasing the smell of coolant for a couple weeks, discovered that the upper radiator hose was leaking at the engine. Based on my schedule and drive schedule, and unfamiliar location this last week, I took my truck to the last people I wanted to - the Ford dealer, where they attempted to charge for the hose replacement. During this time I discovered the nature of how these hoses work and asked the tech why they don't just replace the O-rings ... "Ford Motor Company wants to sell you a new hose with labor" - a direct quote from the Ford tech. And that is why Ford is the LAST place I want to go for repairs I cannot perform. I kept the old hose - any spot where you can get the O-rings alone?

I just bought a used 2000 Ford F150 with the 4.6L V8 engine and I have a question about radiator fluid.
In the owner's manual it says that if the radiator fluid is green is should be changed every 30k miles, but if it is orange color it is only changed at 150k miles. I look at the radiator fluid and from outside the plastic case it is in it has a dark'ish orange/red look. When I shine a flashlight down the hole where you would add more fluid it looks orange/red, but also has a green tint when the flashlight shines directly onto the fluid.
How do I know which kind I have forsure? The truck was bought at a Ford dealer, but I never thought to look at it while I was there.=

Went to start my truck to leave work yesterday and blew the coil on #2. It's happened before and I can fix that. The other weird thing that happened was that the radiator leaked out some antifreeze. Not a lot, but a good 2 foot puddle. The reserve was still full and it leaked from the passenger side at the bottom (below the upper hose). Upper and lower hose show no sign of leakage. I suppose the drain is on the lower end of the passenger side of the radiator and it leaked from there. Would the compression from the engine cause that to happen? Or is it something more, dare I say, like the head gasket blew?

I have an 03 f150 supercrew that had a 4.6L. I am installing a 3.9 Cummins diesel. I will have a separately mounted transmission cooler. I'm using the stock radiator as these engines run cool. It has a transmission cooler built into it. If i just leave the fitting loose, will it cause me any problems. It is a plastic can on each end and i suppose it to have contact with the radiator passages.
