Subaru - Outback :: Disappearing Coolant No Leaks Visibly Or Under Pressure Test
Mar 1, 2011
1998 subaru coolant has disappeared 2 times with highway driving last June and November but it exhibited no leaks visibly or under pressure test. Put fluorescent dye in. Found a hairline crack in neck of radiator under hose and replaced in december. End of february with local driving after siting for 5 days it overheated, sucked up reserve tank and needed a quart of coolant in the new radiator.No leaks under pressure test again and tested ok on turnpike. No smells oil ok. Doing tailpipe heat dye test to see if it's burning coolant and needs head gaskets.

1997 Ford Ranger XLT 4x4 3.0L. So I've replaced my thermostat thinking that would fix the coolant vanishing problem, turns out it did not. Make tank became dry once again and my temp gauge keeps going back and forth from cold to hot.

I have a 2003 Honda Civic and the engine temperature will sporadically raise above normal. Using the heat (even a slight mixture, anything but full cold) seems to worsen the problem.
I've discovered that the coolant is almost always low in these situations, and so I've just been filling the coolant up in the morning before I start the car, but it usually takes about half a liter. There are no puddles or wet spots in the garage or inside the cabin, and I've had the radiator put under pressure for a weekend and it maintained operating pressure, so it seems that there is no leak.
I've had the water pump, timing belt, spark plugs, and O2 sensors replaced. It's been like this for about a year, but it's more frequent in the winter when I use the heat more. Where is my coolant going?

Strong Gas Odor from under the Hood. Mechanic found no leaks. Contacted Subaru only reply I got was "how many miles are on the Car" and take it to a Subaru Dealer. Odor is intermittently.

I had overheating problem on the highway. Towed car to Automotive Clinic - They said I needed new radiator and hoses, so I installed. Couple weeks later, overheats again, this time said I need new head gasket, so I go ahead. Soon as I get back, my car overheats AGAIN. Now back in the shop, and they told me the head gasket blew again...they have taken all apart, and now say they can't find out whats wrong. The coolant is leaking, but they don't know why...it failed hydrocarbon testing. What can it be?

My Tire pressure indicator light starts FLASHING after driving for 15-30 minutes. It does not stay on but continues to flash every 3 seconds. I stop to check tire pressure and my tires are fine. After a couple weeks of this, I took it to the Subaru Service who checked the tire pressure indicators and it said all 4 of them were bad. They reset them versus replacing them and 20 minutes after I left the subaru service center, the flashing started again.
Subaru says that it is unusual for all 4 to be back at the same exact time and recalibrating them should have fixed it. Now they would like to replace each of them for about $150 parts&labor EACH. That seems crazy. Is there something else wrong? Something else they can fix? Is this a legitimate repair? My subaru is the Limited LL Bean version, 6 cylinder, has 60K miles on it and is in top condition. Had new tires put on 10,000 miles ago.

A month ago, my 99 subaru outback started to smoking white smoke. I open the hood and coolant was all over the engine. I took it in and they supposedly put a new radiator in. Three days later the car stalled out and coolant was leaking everywhere. The shop told me it was a bad radiator and replaced it. A month went by, now all the coolant leaked out as though the car had a hang over a throw up out of the coolant hose(lower left hose). Leaving a huge green puddle in a parking lot. What do I do? Has the radiator die again (because the third time is not charming)? Should the shop guys have replaced the hoses when they replaced the radiator the first two times?Is it normal to have to take your car to the shop a month after it was fixed for the same thing?

Have a 2000 subaru outback 2.5l, automatic, with about 245k, I replaced the thermostat,water pump, the radiator and the car is still overheating. both fans are working. no leaking coolant. Maybe this is related- over heats mostly when driving on the highway. But if a shift the gear to neutral and coast for a minute the shift back to drive the temperature gauge goes down. Whats wrong, running out money fixing the car, but love it driving it in the snow.

2000 Subaru Outback. The head gaskets have begun to leak slightly (oil and coolant), even though I brought it in for the recall at 80K and the dealer put in the additive. I recently (111,000 miles) put in another bottle of the additive coolant conditioner and the leak seems to have at least slowed to a trickle. Is it really essential to have the head gaskets replaced? Or could I just keep an eye on the oil and coolant levels and put a bit of kitty litter in my garage? Some of the information I googled indicates that the recall of this car is for an OUT leak and not an INNER leak--which would be worse. Is it true that an OUT leak is not as worrisome?

How does one pressure test for air leaks??? Truck is a 04/04 F250 with 198K ICP sensor in the valve cover.

I need to check the fuel pressure to verify if my fuel pump is functioning. What is the procedure and PSI?
Assume that I open the valve on fuel rail with engine off, then connect pressure tester kit, put key in ignition to "on" position, then pump up to specified PSI???

Bought a 1988 Toyota Celica GT Convertible. I am losing coolant. So far I have done the following: used a leak down pressure tester that shows I have a leak; looked under car for leak and didn't find one, put UV test fluid in radiator, doesn't show any external leaks and doesn't detect any coolant in exhaust; there is not coolant dripping from the heater (passenger side floor); the car does not overheat - the temp gauge shows it in the middle; the car runs great; just had emissions tested and passed with flying colors.

on my dads 2012 TDI, he has about 53K miles on it. one day, suddenly coolant light came on, and the tank was low. Took it to the dealer, they topped if off and said they had no idea. it happened again last Friday, I topped it off with distilled water (had nothing else ATM) and took it to the dealer, they said they did a pressure test and everything is good, no leaks and sent me back.
Today, same thing happened. coolant light came on. Its getting dropped off for the 3rd time, but this time I told them I want answers, not just topping it off.
What could cause this? it seems really odd that a whole tank can empty itself without any visible leaks.

I have a 2004 Honda Civic ex coupe. I have changed the thermostat (twice), fan sensor, temp. sensor. The fan works and when doing an oil change the oil looks normal. No white smoke coming out of my exhaust and I got two radiator flushes, no dirty coolant, and I have replaced the cabin filter. The car doesn't overheat as long as I keep my temperature on hot. If I were to change the temp. to cold it seems like the coolant goes into the reservoir, but it seems like it doesn't go back into the engine. The mechanic that did the flush said that the hoses doesn't to be clogged because the coolant that was removed was green. They stuck an air blower in the heater core hoses and to show that was not clogged as well. The AC worked, I haven't checked in about couple of months. Also when the car overheats there is no smoke coming from the engine. radiator has been burped as well.

My mothers 95 blazer LS coolant is disappearing. A friend said if it's not on the ground than it's in the engine somewhere. oil pan search looked coffee looking?

Even though I had head gasket done/timing belt/water pump & other stuff, 3 months, ago, I'm having to check the coolant level weekly & adding about 1 cup of water to pink coolant every 8 - 9 days. The mechanic who did the work tells me that adding that "little" water in "that amount of time is nothing unusual". I know of no one else who keeps a coolant log. I'm obsessed with this problem. I've spent so much on differing repair to this car - it's as if I bought a lemon.Car has 104K mi. Have coolant problem with no coolant winding up on the ground?

I have coolant disappearing but no signs of a leak anywhere. Oil is fine. Car does not run hot. There is rust in the radiator though. Heater core is not leaking. I have a 2001 Pontiac Gran Prix GT. There was a recall on the cooling system but was not serviced (I didn't own car then). A pressure test was done and it holds pressure. Should I change radiator and thermostat? What else should I have checked?

I've owned this car for a year and a half. A few weeks ago, my car stopped running while i was idling. It started back up without a problem. When I got home, I saw that the coolant reservoir was empty and i topped it off. last week, a faint white smoke came from the hood while i was driving. When I got home, I saw that the coolant reservoir was empty again, so i topped it off again. This morning, the faint white smoke appeared from under the hood again. The coolant reservoir was full and there were no visible signs of leaking anywhere.

The truck has been just terrific, mostly used for towing our travel trailer. Earlier this year i developed a leak and lost 3 quarts of oil before I caught it. I would think with 15 quarts in her this shouldn't have been too big a deal. However, I am now experiencing 10-15 degree swings between ECT and EOT. Before I give the particulars, yes, I have had three new thermostats, two Ford and one brand X.
Anyway, coolant temps are 184-200 depending upon load, terrain, etc. At the same time, oil temps run 205-230. There is no oil cooler to get plugged up. She's got 120K on the clock, doesn't burn oil, no disappearing coolant. I am concerned about blowing a head gasket or other serious damage at these temps, but don't have a clue where to start? Yes, the fan does come on, but still this seems plenty hot.
