Phaeton :: Check Coolant Warning On V6 TDI - No Visible Signs Of Loss
On starting today I had an alarm to check coolant. Never had this before - and the expansion tank was dry. No visible signs of loss - Oil seems fine and free from contaminant.. so I guess not the head gasket!
View 4 RepliesInfiniti :: 2003 - Hard To Locate Coolant Leak / No Visible Signs
Our '03 Infiniti I35 lost large amounts of coolant each time on 2 long trips but when we did a pressure check, we couldn't get it to leak anywhere we could see and no visible signs of where it may have leaked while driving (no drip lines, puddles, etc.). We're not sure where the water pump is located, but have been told it's internal to the engine, so how can we tell if it's gone bad? Would the coolant burn off with no visible signs? We changed the radiator cap but no change. We use a trusted shade tree mechanic, but he's stumped.

I have an 11 F350 6.7. It has just under 200K miles on it. The other day I was driving home, about 100 miles, and my truck's temp spiked. Not like a little spike, but jumped to the 3/4 mark (if there was one) then slowly kept rising to to the overheat mark. I pulled off onto the hard shoulder waited an hour or so to let it cool down, then finished the drive home. All the way home my temp gauge seemed like it was on some sort of drug. It would jump a needle width when I would have to accelerate, then slowly cool to normal after I got up to cruising speed.
Up until this point this truck has been exceedingly reliable. I pull a 13k 5th wheel once a month and drive about 40k-ish miles a year. I also had to refill my degas bottle up to the fill line. Took 2 gallons of Ford VC-3-B Coolant and water mix. After a short run to verify the problem, it took another 1/4 to 1/2 gallon of mix. But, no overheating. No signs of leaks anywhere. Just a strong scent of coolant on shutdown outside the truck. Pressure tested the cap, I don't have a way of testing the system pressure.
Data from Autoenginuity:
Engine Oil temp 195-202 Degrees
Engine Coolant #1: 188.2-199.5 Degrees.
Engine Coolant #2: 125.5-129.9 Degrees.
I have the full CSV file.

View 5 RepliesCivic - Honda :: 1998 - Coolant Level Drops In Reservoir With No Visible Sign Of Leak
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?
Ford 7.3L Power Stroke (1999-2003) :: Oil In Coolant / Oil Level Drops But Coolant Level Stays The Same
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 just purchased my daughter a used 2006 Prius and we found water in the rear right passenger floor board this morning. We have only had the car 3 days. There are on leaks that I could find inside the car. I looked in the tire well and water was there and also near the 12Volt battery also. The brownish/yellow sealant in the tire well that goes around the bottom is also in my 2010 Prius but I noticed that my daughters 2006 Prius the sealant or what I believe to be bodyflex is cracked. I am going to have a body person look and see if he agrees with me that this bodyflex is cracked.
View 2 RepliesPassat (B7) :: Loosing Coolant But No Visible Leak?
I started loosing a bunch of coolant on my tdi which is still under 36k and there is no visible leaks anywhere
Took the car to the dealer last night to get it checked out and they were ready to send me back home telling me there is no issue since they don't see any leaks under the car
Either way after telling them that I have already gone through 2 gallons of coolant they decided to top off the coolant and ask me to drive 200 miles.
I drove 156 miles last night since I need to get this issue resolved and now the coolant tank is empty again... sitting at the dealer while I'm typing this.
Impreza :: Coolant Leak But No Visible Sign Of External Leakage
I've had to replace my radiator twice due to it overheating. I am noticing coolant level going down but I'm not seeing any signs of an external leak. My garage is saying it is probably internal and going into the engine. Says I probably have to replace the head gasket but that will be very expensive.
Could I get some further feedback on what it could be and what else I could do? I am also getting a check engine light on a "lean mixture" issue. Not sure if they are related.
Jeep - Coolant - Liberty :: 2006 2wd Using Antifreeze A Lot - No Visible Leak
I have a 2006 Jeep Liberty (2WD), 149k miles, that has been using a lot of antifreeze lately. I am using a full 50/50 gallon mix about once a week. I do not have any visible leaks. My heater no longer works and I was not sure if that may be a cause. The check engine light is on, but has been since I purchased the vehicle in 2012. I thought it may be a gasket, but do not see any white smoke from the exhaust. I am not hearing any strange sounds, so I am perplexed.

View 9 RepliesMalibu :: 2002 3100 V6 Losing Coolant Over A Gallon A Week But With NO Visible Leak
My 2002 has had a slow coolant leak for quite a while (maybe a quart a month). Now, however, I am losing over a gallon a week, but with NO visible leak!
The oil is clear, with no signs of antifreeze in it, so I am guessing the head gaskets are ok. But I am perplexed as to where my coolant is going!
After reading more threads in the forum, (which I should have done more thoroughly before posting,) it seems that I may indeed have a head gasket leak. From what I've learned, that would cause me to lose coolant through the exhaust while driving, and would explain why I don't see a visible leak anywhere. Am I on the right track? Before I replace the head gaskets, are there any other causes that may have a simpler fix??
Lumina :: Low Coolant Light Goes On - Coolant Level Sensor?
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?
Ford 6.7L Power Stroke Diesel :: 2016 - Coolant Slowly Going Down / No Longer Visible In Clear Section
When I got my 2016 back at the end of last October, the pink coolant in the main degas bottle was just visible in the clear top half of the bottle. By the time 5k miles rolled around, the coolant was no longer visible in the clear section. At oil change time, the dealer "topped" it, resulting in it being visible in the tank again. 3k miles later, the coolant has disappeared below the clear part of the bottle again. What gives? The secondary bottle level has not budged. Its clearly not losing a lot, but it is definitely going down slightly.
