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 have a 1999 jeep cherokee 4x4 four liter inline 6. have a coolant drip at bottom radiator hose, change hose. but still drip. Could water pump be leaking. and it running down on the bottom radiator hose.
View 4 RepliesI am new to working on cars. SO i think my water pump went out on my 1991 celica gts, there is a large water leak where the bottom hose from the radiator connects to the what i presume is the water pump or thermostat, need to know if I am on the right track...
View 5 RepliesThis 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.
2004 4.6 V8 Trition ,two wheel drive, STX Pickup. By removing the bottom radiator hose, will that allow all engine coolant to be drained from engine? If not, about how much coolant will remain in the engine in terms of quarts or percentage of total vehicle coolant capacity?
View 1 RepliesSearched several times over the winter. Finally tore each hose out one at a time and went carefully over it before returning or replacing.
Turned out to be the long formed semi flexible vac. hose that runs from the gas fumes purge tank control valve group to the throttle body across the top of the engine. Ripped it out, on one of the bends was a small crack all the way thru, apparently would open up wide when stressed and cause problems. Mainly on hill pulls or hard acceleration but not every time. NO hair left after this one.
Replaced, deleted the codes. Runs like a top.
Still amazed at how much power these 4.0L V6 OHV Fords have from low speed on an uphill on ramp drag race.
stirs the old hot rodder blood.
Front diff does not leak but seems to get alot of oil coming out vent hose. enough to make a mess and require more top offs.
View 4 RepliesI have coolant leaking from the bottom of this hose on my brothers car. I am not very familiar with the BEW's as I drive an ALH. Just looking for info about part number or name on this hose so I can get a new one. Has a part number MH3364 on it but that is not working anywhere.
View 2 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 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 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.

My wifes 2002 gls has a coolant leak from the top radiator hose. I put a new hose on and two new clamps on the leaking end and it still leaks!! I have never seen anything like this and I am not sure how to stop it.
View 3 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?
Where this small leak coming from. Under my radiator hose. Took a pic of the leak.
View 8 RepliesThe inter cooler to throttle body hose and it seems to have coolant all over it.
View 12 RepliesI smelled antifreeze when walking by my fiances Sonata, so I popped the hood and saw there was a small leak from the upper radiator hose, where it meets the thermostat housing. I adjusted the stock clamp, but the leak was much worse.
I swapped it out for new clamp that you can tighten, and all is well again. But, what I noticed when I had it off was that the metal neck of the housing was really corroded. Only 15,000 on the car, so I was surprised to see that the corrosion on the metal had already built up causing the leak (pushing the hose away from the housing). I scraped and scuffed to get it clean again, but just wanted to give you all the heads up in case you notice a leak in the same area. The antifreeze tested good and is really clean.
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 had my LS at the dealer this morning getting the fuel regulator recall and they noticed that my radiator had a very small leak at the nipple where the overflow hose is connected. From what I've read, this is a very common issue that I probably caused by leaning on the fitting at some point while working on the car.
I'm no stranger to DIY and am willing to take this on. I'm looking at replacements online and I see two brass fittings at the bottom. Are those for transmission cooler lines? If so, wouldn't replacing the radiator cause the loss of some transmission fluid?
I just bought a used 09 yaris, 5 speed manual tranny. There seems to be a small coolant leak on the top hose coming from the radiator, the one that connects to a plastic flange or adapter and then go's to the engine block. The car does not get hot and it drive fine except it leaks at that spot. I try using a regular hose clamp and still leaked. Is the thermostat not opening up or is the water pump intermittent stopping? or something like that. Or maybe the hose itself is bad. Since this is a used car who knows what the previous owner did, I might change out the hose over the weekend and replace all the coolant to the correct Toyota long life system. to be on the safe side.
View 3 RepliesReplaced pass side cyl head 7 years ago and now I've a misfire on cyl 1. Did wires and plugs as a matter of routine. Giveaway was rust deposit on rad cap. I always keep a strong coolant mixture and the rad is fairly new. Did a cyl pressure differential test and had bubbles coming out of rad. Funny thing is that had a rough few seconds on start, then smooth from then on. Getting my self fired up to tackle it. Have full gasket set and head bolts. Got a new head today. Am at 470k miles now.
