Ford 7.3L Power Stroke (1999-2003) :: Oil In Coolant / Oil Level Drops But Coolant Level Stays The Same
Aug 4, 2016
My friend bartered for a '99 F250, 2wd/auto, 4 door, 7.3, 258k miles.
It had reportedly sat for one year, though the expired registration sticker and other things point to it sitting for two.
It ran low on oil, sputtered and died. Oil in the degas tank. Filled to oil to mid way on the hatch marks on the dip stick.
I drove it 25 miles to my house, and the oil level is not reading on the dip stick.
The sludgy fluid level in the degas tank is unchanged. Where is the fluid going?
I will refill the oil to see just how much it lost in the 25 miles if it important to someone, but I prefer to not waste the oil.
My first plan is to remove, inspect and replace the oil cooler o-rings. Even though the dealership charged him for this, I don't trust that they did it right. I think it is the easiest and mostly likely place for oil getting into the coolant.
It does have a really long crank before there is enough low pressure oil for it to start. At the moment I think this is a separate issue.
The dealership also charged him for a replacement injector. No idea if they replaced the cup or not.

I recently noticed a small bead of coolant on the driver's side of my tie rod coupled with low primary coolant level, so I took it to the dealer expecting to face a radiator issue (50k miles). Instead they said that the lower radiator hose was leaking and recommended replacement. Thinking that we were still headed down the radiator path, I had them do the job.
Upon inspecting the removed hose, I could find no obvious fault, so I inquired further. They clarified that it was the seal which had failed (I guess replacing the entire hose is the fix for this?), that it was contaminants that build up in the coolant which attack the seals, and that I should expect it to happen again if I don't flush the coolant every 10,000 miles (yes, ten thousand).
I asked if he meant to say that I should check the 'coolant additive level' every 10k (instead of 15k) and he again stated that a full flush was necessary every 10k miles and that it was a "maintenance intensive engine." This can't be right.

2012 6.7 .... Noticed my coolant level in the primary tank was low. Thought it was totally empty but it had about a half inch left in it. Topped it off and also needed about a quarter inch in the secondary. I would say about a half gallon between the two. Truck was at about 36k. Has 37.5 on it now and haven't noticed any loss. Never smelled anything, no signs of any leakage. Oil looks fine. Is this 'normal'? Owners manual says to check and add. Never had this with a gasser or any of my tractors over the past 30 years. This is my first light diesel.

I have a '98 Honda Civic with 230K miles on it. Last month, I suddenly saw few drops of coolant on my garage floor. I opened the hood and saw coolant splashed over the engine. I opened the coolant reservoir and it was empty. Surprisingly, the car never overheated and neither did the temp needle go up. I took the car to the mechanic (Honda shop) and they said that the radiator is leaking. I replaced the radiator and after driving for couple of weeks, the same issue re-occurred.
The coolant ran low in the reservoir and there was coolant splash over the engine. I took the car back to the shop and they said that the hose was not properly installed. They fixed it and said there is no sign of leak. I have been driving for a week now and check the coolant routinely. I have noticed that the coolant level has again dropped significantly. But, after the last fix, I do not see any visible sign of leak. There is no evidence of coolant anywhere under the hood. I am not sure if there is something else going on now. Is there something else I should check?

On Sunday I'm driving to the store my LOW COOLANT light goes on. So I buy some coolant. I get home let the car cool off and check my radiator, it is full. My coolant recovery tank is also at the proper level.
Been three days already checked levels again and I'm not losing any coolant.
What the car is NOT doing:
1. Not losing fluid
2. Not running hot
I'm thinking coolant level sensor?

I filled my coolant yesterday after driving to the "max" line. Today when I awoke it was right at the "min" line. I didn't see any noticeable liquid below the truck, except under each front fender but I think this was water from the dew evaporating/condensing and running off the truck. What happened to the coolant or did it just cool down and condense. It got pretty cool last night (mid 40s). I have an 02 f250 5.4L ... I feel like there is a leak somewhere, any link to or a procedure they can explain for finding it?

So I know it's kind of a loaded question, but how low can the oil level get before a noticeable lack of performance occurs? Basically, how low does the oil level have to get before the truck will no longer pull itself up small hills at interstate speeds (70 mph)?
I will describe more of what occurred later on, but I want to get an idea if what I am thinking may be possible.

I'm fresh out of the perverbial womb to this place and only about a toddler when it comes to my truck. However I do want to learn! I just recently invested in an 02 XLT F350 7.3L. I'm in love with the truck except the leaning forward aspect. I am debating on leveling it via lowering the rear. Any thoughts? Things I need consider that will happen if I do? How would you do it? Would you do this over raising the front? I've heard raising the front can mess with the suspension geometry and that's not a good thing to do!

I have 2010 explorer. I have to add almost 200 ml of coolant in my reservoir every week. there is no sign of a leak from anywhere even at thermostat manifold as well. but one question, when the car is running for at least 1 hour, the coolant level at reservoir shall be around FULL HOT Level and when car cools down overnight, it should be at around FULL COLD LEVEL. is it right? if yes, then my level remains little more than FULL COLD when the car is hot and when it cools over night, level goes little down than FULL COLD. like this every week I have to add almost 200 ml of coolant. radiator CAP is okay and I replaced it few months back. no apparent sign of leak. any clue what can be reason?

I've been having a very erratic fuel gauge issue as of about 2 months ago. My fuel level would register full, when in fact I knew it only had 1/2 a tank or so. Then 5 minutes later it would be pegged on full. Under a 1/2 tank the gauge would read any where from 1/2 to empty from 1 minute to the next. So last week I decided to drop my tank and take a look. I was thinking maybe my fuel sender was broken, maybe a loose wire in the tank, or even that my float had dropped off in to the tank.
After dropping the tank, I removed the PK-Up and sending unit and everything was intact. I placed my ohm meter on the sending unit and it checked out fine. So I took the Pk-up and rolled back up underneath the truck and plugged it back in. I had my son turn the key on and off while I moved the float to different levels in order that it would register. It registered empty, 1/4/, 1/2, 3/4 and full just fine as I moved the float to those levels. If you leave the key in the run position and move the float, it won't register or better said, the in cab gauge will not adjust with the movement.
You have to turn the key off move the float and hold it there, then have your assistant turn the key on and the gauge will show the position that you've moved and held it at. I simply removed the plastic cover from the sending unit, and sprayed it down real good with electrical contact cleaner. I didn't scrub the copper contact area at all.
I was concerned that scrubbing might remove more than I wanted to, and really mess things up. I attached an Ohm meter and checked resistance thru out the float travel. All checked out good and I reinstalled it. So now my fuel gauge is working as it should be. I did make a video while I ohmed the Sender Unit thru it's travel, but for some reason it won't load.

Tonight we left baseball field and my 2005 excursion was white smoking all the way home. I Stopped Several Times And Checked Coolant Level And It Never dropped. I let it sit for a hour and coolant level is still at my black mark. So does this mean it's a injector? It poured down raining so I'll have to wait till morning. Will scanguage show any codes for injectors. If so I can program in the morning.

Have a small coolant leak. The level is dropping and I can smell it but I cant find it. The radiator was new at 100K miles and the heater core is bypassed. No evidence on or near the hoses, water pump or radiator. Getting ready to replace all the hoses because they are overdue but I would like to find the leak(s) first.

Level in the tank going down? I don't appear to have any leaks but it's now down to the "Min" level cold.

My Touareg has 9400 miles and yesterday I checked the coolant level when cold. Inside the reservoir there is an awkward yellow cylinder with the max and low words. The manual is not very detailed about where the level should be like the oil, or at least show a picture. I noticed that my coolant is right underneath the letters LOW for the low mark. I would take it that I need to add, but need to confirm whether or not that is an OK level. Could LOW be the translation by the Germans for the cold mark? My American made GMC Envoy has a clear reservoir with precise max-cold-low marks so you can actually safely see the level even when hot and be sure about it. I ask this because today I had the 10000miles service done and the tech said the level is fine.

I've been noticing my coolant level seems to be going down. The last two times I had it in the shop they reported a low level and refilled it. Followed by today I noticed it's near empty on the reservoir. It's disappearing but where it's going. No drip marks underneath anywhere on the driveway or the car. No pink sludge on the bottom of the radiator. No pinkish hue or any indication it's getting into the engine oil on the dip stick... I'm at a loss here.

I have a 2002 Ford Explorer and I am still trying to figure out why the coolant will overflow in the radiator reserve tank. I put in a new thermostat and a new cap to the overflow tank. When the tank is cold, sat over night, I put in new anti-freeze to the cold coolant line. Then I start up the explorer and let it run for a while. The temp gauge goes up, then drops a tad and cold air comes out of the vents.
After I rev up the engine, I see the coolant level starts to rise in the overflow tank, then it goes to the top and starts to leak out. This takes a while being the thermostat has not kicked in to suck the fluid in. Before this happens, the heater core lines are luke warm. After the tank overflows, the remaining gets sucked into the engine and I get nice warm heat. What causes this. I had the test done to see if the head gasket is bad. The test was negative.

My coolant level sensor is bad. How do I replace it? I understand that there is a retaining metal wire holding it on. How do I get that wire off?

Coolant level message on my 2004 Ion won't go away. I have pulled the overflow tank and cleaned and flushed it. Checked the sensor with my multimeter for continuity, checked fine. Checked and remade wiring connections to the sensor. I thought maybe the float material was the same as would be in an hydrometer so it would only float in the correct mixture/protection level of coolant. Flushed and filled the system with 50/50 mixture of Dexcool. That theory was incorrect. The only thing I've seen so far that makes sense is a "software issue" that was mentioned in another discussion I read.

At the end of last winter, I got the warning flash that my coolant level was low. So I topped up (about a pint or more)About 3 weeks later I had to go through the same scenario !! but then it started to get hot outside and my air conditioner mode took over and lo and behold - no more coolant loss.!!?? Now that winter and cold weather is back - so is my leak!!
So I run off to the local dealer and they get the car up. And drop the belly pan with the engine running and the heat cranked up. the mechanic said he found a dripping hose coming from UNDER the intake manifold.
The engine is a 2002 2.8 v6....

My coolant level keeps dropping really low underhood and the light comes on on the dash, but I went and bought coolant, opened the hood, and the level was back to normal. Where is it all going? Should I add any when it's low if it's coming back? This just seems weird.
