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?
View 9 RepliesIs 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.
View 13 Replies2001 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.
View 2 RepliesI'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.
View 14 RepliesHaving problem with the lower radiator hose rubbing on the serpentine belt...
View 1 RepliesJust had to replace radiator at 38k on my 2012 SD. Now I have another leak at 41k. Looks like it's wherever the lower radiator hose leads. Kind of a weird junction. I don't think it's coming from above there, but not sure. It's the primary dgas bottle that was low. The radiator was covered under my ESP. We'll have to see what's up with this one. Been eying a denim blue SD at dealer, thinking this is going to talk me out of it though. Not especially happy right now.
View 3 RepliesI have 98 passat V6 and the lover radiator hose is leaking at the connector between radiator and the hose. Do I need to change the whole hose or is there maybe an o-ring that should be changed? How hard is to remove the hose? Do I have to go to the dealer?
View 2 RepliesI'm trying to troubleshoot a leak on my 08' F250 with a 6.4 powerstroke. It's been dripping coolant when cold pretty aggressively. Once the truck heats up, the coolant leak seems to mostly go away.
Here's a picture of the drip, it's marked by a dart, so you can see the location from the top (second pic). The radiator house connection around the engine seems dry.

What's hidden here that could be causing the leak?
I picked up a used 99 Passat with 79000 miles. I just changed the oil and found the pan pretty well sludged up - typical from what I read on the forum. I noticed the coolant looked pretty diluted - so I drained and filled with 50/50 mix. After starting I felt for the upper and lower hoses heating up and the lower one never did. I guess I should have tested this out before draining and refilling - also typical. Question is - is this a thermostat issue? My Haynes manual says if the top hose becomes hot the thermostat is operational. Heater has plenty of heat, temp gauge stays pegged at 190 degrees top dead center of the gauge.
View 5 RepliesI 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.
View 6 RepliesI have checked and cleaned my K&N air filter so I din't think thats the problem... may be just old & weak... it collapses on acceleration and stays that way til I pop it out. What I can install? Don't want the same one in there now, something that is harder would be ideal. Been searching online for one that will fit my car. Pic below.
View 5 RepliesI 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?
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'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?

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?
View 5 RepliesNoticed this past month on colder days my upper hose is collapsed, typically a symptom of a bad radiator pressure cap.
This hose is connected from the water pump to the radiator. The radiator is connected to the Degas bottle which has a nonstandard radiator cap.
Do these plastic caps vent the same way a typical cap does?

This weekend while towing a light load I noticed my FWT and EOT starting to climb rapidly, EOT reached 260 FWT I think about 240. I exited the interstate to find I had a busted radiator hose. I replaced the hose and filled the system with distilled water, but didn't add antifreeze at this time. The system wasn't completely empty.
I noticed once back on the road my EOT seemed to be higher than normal but FWT seemed to be normal. Could the lack of antifreeze cause a greater delta between FWT and EOT? I have seen articles which state do not use Ford Premium Gold Coolant, but to use CAT EL-1 coolant instead. Which should I use?
This is strange, Had the truck for about 3000mi bought it at 147k now has 150... Any way it runs great but the radiator started leaking from the seam close to where the bottom hose is. I have since changed the radiator about a week ago 500mi a week work truck.
Now it seems to be leaking from the very same area, what I mean is the area around the hose is dry but just up the seam a bit it barely leaks, and mainly after the truck cools off at night. These radiators seem extremely low quality, is there a substitute higher quality.
Also of note mine is the 1" core, I was told there are others but they will not fit, I must agree it seems nothing else would fit due to space constraints. These radiators just kinda sit in a cradle and aren't really under any stress that I can tell so it doesn't seem as though that would be the cause.
Also of note the shop where I bought the new one took it out of the sealed box and tank pressure tested it as they do for all new sales, no leaks, I have not pulled it back out yet cause I would like to get some thing less flimsy if it exists.
Just picked up my truck from the dealer after a trans flush. While it was there I had them replace both windshield wiper nozzles. They called and told me the hoses needed to be replaced as well--- OKAY fine do it.
Come home and decided to "make sure" the trans fluid was at the correct level.
Open the hood to discover a loose black hose approximately 1/4" or so in diameter coming out of the radiator shroud directly at center of the top. The end of the hose was somewhat towards the passenger side battery.
I figured okay the tech probably just left my old windshield wiper hose on top of the motor and forgot to discard it...
I follow the hose and it appears to go in between the rubber seal for the shroud and the plastic housing. I looked back behind the fan and can see the hose twirled around an aluminum or stainless steel pipe coming up just in front of the fan but behind the numerous condensers...
MY question is two fold: Should this hose be here, or is it indeed the wiper hose that got sucked into the fan?
if it is supposed to be here, what does the end that was leaning towards the passenger battery connect to? it certainly appears to have been previously connected to something whether the washer or some other barbed fitting....
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...
View 1 RepliesI'm about to tear into a friends 2002 B2300 4 cyl. The lower hose that comes off of the coolant reservoir is leaking in the metal part of the line. Close to where it bolts to the block. At a glance, it looks like I have to pull the whole top of the motor apart to get it off since the line runs around behind the motor. Is there a trick to removing this coolant line without a lot of teardown? I'm not finding it at parts stores so I guess it's a stealership part.
