I didn't realize the 6.7 had two places that you need to monitor your coolant level. I've kept an eye on my coolant reservoir for the rad due to radiator failures reported but just today noticed there was another one for the intercooler. Mine was quite low. I'm sure most of you knew it was there but for those that didn't, keep that baby topped up I can't imagine having a hot intercooler is good.
View 7 RepliesMy friend is working on a 2004 6.0 F-250 and it has used 75% of the coolant in the overflow bottle in 5 days. Can't smell coolant either. The inside of the tailpipe is wet soot black and there are wet spots on the tube coming from the intercooler to the turbo at the turbo and the intercooler. He's thinking EGR cooler.
View 6 RepliesI was pulling our 14k fiver home after a weekend at the lake and I heard a muffled pop sound. About a minute prior I had checked the gauges and everything was normal. It honestly sounded like a chinabomb tire on the ttrailer had popped. Puled over and all tires were good so I popped the hood .....
Here's the bottom half. Is this possibly a warranty item? 2011 with 61k. And no mods. Plus a lot of oil on everything is that normal?
2011 6.7 F350 .... 120,000 miles ....I have been smelling anti-freeze for the last couple of months but have been unable to find a leak. Going through a minor amount of fluid but no indication on the ground ...
Searching deeper today I see the bottom of my intercooler is wet - remove the air hose and there is some fluid. I am assuming there is NOT supposed to be fluid in the air intake hose - correct?!?!
Any thoughts or history on these intercoolers letting-go and leaking internally?
How do you tell if there is water fuel drain plug check area ? Fuel always looks the same to me.
View 14 RepliesMy truck just had it's check up at the dealership. On the slip it stated ATF fluid on rear housing. The tech said "No big deal maybe take a better look and maybe replace rear gasket later down the road". So first where is the check hole as I know there is no dip stick plus I think you use your finger to figure level. How far up should it be? I go over my truck about once a month looking for stuff and would like to include in my inspections.
View 4 RepliesI've been having transmission fluid leak from my truck for a while now. Very slow leak. At first I thought it was a hard line and replaced it but it was still leaking. Then I think I found where it was coming from. It looks to be fluid dripping on the bottom of both sides of my intercooler? On both identical spots. I am guessing perhaps I had a crack on my transmission oil cooler and driving blew it into the fins of my intercooler. I took my old one off and couldn't visibly see one. I have a brand new trans cooler installed now. Haven't drove yet as I am waiting on brake parts? I couldn't think of anything else on why it would leak off the intercooler?
View 6 RepliesI know checking your oil level is a pretty easy thing but I am having a serious issue right now. I checked my oil and my dipstick has oil on it but it isn't leaving the napkin wet. Like there is oil on the dip stick but it just doesn't seem right. Nothing on the ground were I stopped at before I got home. How long will it run without causing damage?
View 14 RepliesI have coolant blowing out of my coolant reservoir when ever i hold it to the floor it does it with or without the banks programmer... 6.0L power stroke...
View 14 RepliesWell got home and the front of the truck was covered in coolant. I must have driven 2 hrs after I noticed no coolant pressure, but temperature was great so figured it was another crappy cap. Looking to get a quick turnaround. Need to go out of town for work Saturday so I have this week to get it done.
Just put a stock unit back in? I don't think I need to do anything else in that area. Belt/pulleys/radiator all done last spring.
This weekend my friend and I plan on doing a coolant flush, new Mishimoto thermostat housing with high temp thermostat and install a Mishimoto coolant filter.
Truck currently has some unknown green coolant in it and Im going to replace it with Rotella ELC. I plan on doing a couple hose water flushes then follow with about 5 distilled water flushes. I've been reading about putting some Cascade in on first flush to dissolve any silicate goo that might be in there hanging out. I might give that a try. Im sure I can manage this part from all the stuff I read about doing flushes.
This is the part that looks like a little more work involved than the flush. Doing the thermostat kind of worries me because of the tight area in there to work with the fuel line and the EBP sensor being right there. The current thermostat holds temps around 175-185 under normal driving. I bought the new Mishimoto thermostat housing with the high temp thermostat installed in it when they had their pre sale going on for the housing.
I decided to just go with the whole thing because of all the stuff I read about people having issues with the thermostat not fitting the older housing correctly since Im certain I have the original housing from 2004, like everything else that's still original on my truck. I plan on removing the thermostat before doing the flushes and then installing the new housing and thermostat and coolant filter before I add the ELC.
The coolant filter install looks fairly simple to do so I should be ok with that.
I have a 2001 f250 7.3 and I had started to notice I wasn't making as much boost I thought I should have been. I looked around and found a tear in the cold side CAC boot. My question is what is the best option for replacing it, something like RiffRaff or oem? Also should I look at replacing all the boots or just the two up top?
View 14 Repliesjust installed all my intercooler boots with plenum inserts. Had a torque wrench set at around 14 lb/ft and all of a sudden POP! the inside of nut on clamp stripped out. of course its on the boot going to the plenum. Any one have this happen? Brand new clamps from riff raff. Am I cranking to hard, maybe torque wrench isnt accurate, i don't know but didn't seem like i was getting on it enough to do that. the threads came out on the bolt looking like a heli coil. not to cool. Google it and another forum popped up , everyone was saying to crank em down. apparently you cant do that , not even 14 lb/ft. Anyways went to hd and threaded the bolt into their thread gauge. the only one that seemed to fit was 1/4-28 fine thread( which they don't carry in a nylon thread lock nut). Is this the correct size? How to gauge how tight to tighten the nut?
View 4 RepliesI am going to install a coolant filter on my 2004 6.0 E350 van. I have read threads about bypass filters and full flow filters and I started asking myself "Why use a bypass when I can filter all of the coolant?"
Is there any reason why someone should use a bypass filter? I bought the van used knowing I would eventually have to do most if not all of the 6.0 repairs. IPR sells a complete coolant filter.
I talked with the people at FICM repair and they suggested I do my research but leaned towards the IPR cooler. Ed spent a good 30 minutes on the phone answering all my questions and never asked if I wanted to buy anything. If anything, he was trying to stop me from throwing money at the van until I isolated what needs to be repaired.
I already bought the Sinister Kit and requested a return.
I just noticed a wire burned in half on the front side of the intercooler plenum. See picture below,
Here is the left side showing the green wire stub going into the wiring harness on the front side of the intercooler plenum,
And this is the right side showing the wire going into the air intake duct between the turbo and the air filter,
I don't think it's been in this condition very long.
ive noticed my boost has been going down lately. At first I thought it was a boost leak so I replaced all the intercooler boots and both sides of the intercooler pipes. That diddnt change anything at all. I recently got new injectors (200/30%) and a hydra tune for them and it was quick the first few days i was running with that setup, my boost has been dropping and currently at WOT I can't even get to 10lbs of boost and it is noticeable driving, it's slower than it was stock. There was no play in the shaft of my turbo and the turbo in there is only 2 years old. Could the turbo be bad already? Or is there anything else I can check before buying a new one. I have an upgraded hpop and the 6637 intake.
View 13 RepliesI am having a heck of a time finding this coolant leak. It drips off the power steering pump. I replaced the upper radiator hose and the heater "y" hose that goes to the bottom of the Degas bottle. I recently replaced the lower radiator hose as well. So the truck runs normal. When the system is under pressure I do not see any leaks. But after the engine is completely cold it starts leaking a small puddle of coolant. Its appears to be coming from the power steering pump. But I am sure its something above or near it. This is on my 2005 Excursion with a 6.0. Can the water pump be going bad and leaking this direction. I would expect a water pump to leak straight down the middle of the engine. What to look for? The thermostat seal stays dry. but it has to be in that area. What is really messing with me is. When it is hot and pressured up It does not seem to leak. Only after it has been sitting for hours and cools off..........What the heck!
View 14 RepliesI have a new(and flushed) oil cooler and new thermostat and my coolant and oil temps never go above 190. They are always within 3 degrees at most but is this actually losing fuel mileage? I thought these were good numbers, could be wrong though.
View 1 Replies1st f250. The coolant is a little low and wanted to add some to it but I can not get the cap off. It will spin and spin either way I turn it. I've tried pulling up and pushing down on it and no results.

View 6 RepliesI am looking for some insight on an issue before I lose sleep over head gaskets. Headed out today in the truck, and no heat whatsoever. Im thinking maybe a vacuum issue, but 4wd (esof) and all vents move just fine. About 10 miles in I over heated at 236 ect. After cracking the coolant cap there was no coolant. I havent actively monitored it but last i checked was fine.
The exhaust does not smell sweet and I see no puddles or any evidence of coolant splatter before today when i refilled it today. There was some tonight but im thinking that's from me spilling some today. Egr is also blocked off. I need the truck soon for plowing so need this resolved asap.
