Ford 6.7L Power Stroke Diesel :: 2012 - Coolant Leak From Lower Radiator Hose

Just 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.

Ford 7.3L Power Stroke (1999-2003) :: Radiator Leaking - Replacement?

I have a 99.5 with 400,000. on the engine. It has been a great truck but it is time for the some TLC. I have a little leak on the radiator and the water pump and would like to replace it. I am just looking for stock.

I have a 13 yr old that grew up sitting on my lap as we drove the dirt roads around the house and on the ranch. He has been driving this truck by himself (on the ranch) as soon as he was able to reach the pedals, around 8 or 9. His happiest day will be when he gets his drivers license and can drive the truck to school. So I have a lot of work ahead of me on this truck.

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Upper And Lower Ball Joint Replacement

I have recently replaced both tie rod ends and found out when I took my truck for an alignment the mechanic stated that I had bad driver side ball joints (upper & lower) I confirmed this with SEARS and they stated that it was all the ball joints upper & lowers! the Haynes repair manual (1999-2010) states "ball joints on 1999 through 2013 2WD models were not replaceable".

Passat (B5) :: 1999 - Lower Radiator Hose Stays Cool But Top Is Hot

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.

Ford Super Duty (1999-2016) :: 2008 F250 - Coolant Leak Above Lower Radiator Hose

I'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.

Pic from Top ....

What's hidden here that could be causing the leak?

Ford 6.7L Power Stroke Diesel :: Upper Radiator Hose Leaking?

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?

Ford 6.7L Power Stroke Diesel :: Upper Cooling Radiator Hose Collapse?

Noticed 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?

Ford 6.0L Power Stroke Diesel :: Blown Upper Radiator Hose And EOT Temps

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?

Ford F-150 - 1997-2003 :: 1999 - Radiator Hose Have No Pressure?

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.

Honda - Cr-v :: 2000 - Coolant Dripping From Lower Radiator Hose

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.

Ford 6.0L Power Stroke Diesel :: Radiator Hose Split While Traveling - 250 Degree EOT After Coolant Loss

Recently I had a radiator hose split while traveling. The EOT got up to 250 degrees before I could pull over and stop the truck. I flushed the cooling system with water, replaced the thermostat, and added Ford Gold coolant as per the recommendations in the Tech folder. My oil temps are higher now than prior to this incident. Unloaded on a flat road my deltas are about 10 to 12 degrees @ 60 mph.

My water temp will stay around 190 to 195 degrees while my EOT have reached 212-215. I pulled a small utility trailer and saw a delta of 17 degrees this was at about 75 mph. Typically unloaded I would only see a delta of about 8 degrees and this was at 80mph. My question is do you think a EOT of 250 would burn the oil, I had Shell Rotella T5 5W40 in the engine. Would it be possible that the oil cooler is partially plugged from this temp?
