Subaru - Outback :: Overheating After 30 - 40 Minutes Of Combined But Mostly Highway Driving
Mar 1, 2013
I have a 2001 Subaru Outback Limited with 135K miles on it. In the last year, I had two complete head jobs (the second because the new water pump failed while on the highway). In addition, I have had multiple water pumps, lots of thermostats and a new radiator installed. The last thermostat is an OEM. The car had been running fine for about a month and now overheats after about 30-40 minutes of combined, but mostly highway driving. At first, the gauge would rise to about 3/4 and then drop after about ten seconds, but now it goes to almost red and drops to 3/4. If I blast the heat, it will drop pretty fast. My mechanic told me that while diagnosing an earlier overheat issue (just before the good period), he noticed that the gauge would rise, but the computer temp would remain stable. He tried a new sensor, but said it made no difference, so he returned it. What is left to replace?

My 98 Subaru only overheats when going above 60 mph for more than 10-15 minutes. When it does and I pull over,the cap has blown off of the coolant tank. After letting it cool off and adding a bit of coolant - it doesn't occur again and I can drive for hours at high speeds. I drive the car every day, up and over mountain passes and up to the ski hill and never have a problem any other time. I know subarus have a tendency to blow head gaskets, but wouldn't there be other warning signs?

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?

Subaru Outback 2003 4 cylinder runs ok first several minutes then starts to skip. Appears to be maybe EGR related? Plugs/wires/dist ignition are ok. The car was double filled with oil the started, smoked. Could that affect the ECR or PVC? Could this damage the fuel injectors?

My Subaru just had the thermostat replaced, and it seemed to work until the wife took it she said it over heats when not driving the fans are working, it's over flowing out the reserve tank the fluid looked good when changed the thermostat so I don't think it's the head gasket my next guess would be either the water pump... After I last changed the thermostat and test drove it I felt the upper radiator hose it was hot but the bottom one was cool/warm.

I have a 2002 Subaru Outback that has started overheating only when I try to go up into the mountains. It starts within a few miles of starting up a steep grade and cools down the instant you start down the mountain. I have had no problems with regular driving conditions. The only pertinent info might be that it did have a coolant leak last summer and overheated then.

Subie was driving fine...drove it on highway and went to park and NO reverse. At first, I couldn't shift into park either, but then I was able to shift in park. I can move the gear to reverse, but nothing happens (engine just revs and car wants to roll forward as it is on slight incline. Hubby checked trans fluid and it was a bit low, added fluid, but still no reverse.

I own a 2002 Outback. It is overheating. We have replaced hoses, thermostat, water pump, the temp sensor, had the radiator tested. Nothing has changed our problem. My husband is at a loss and the mechanic who has is now has no clue as to what else it could be. The mechanic is referring to it as a ghost problem.

My wife has a 2005 Subaru Outback XT w/auto trans, about 135k miles. We live in SoCal.The car runs great...well, most of the time. During the summer, or when driving up steep mountains with the AC running, the needle will climb steadily north towards overheating. Call me timid, but I've never been curious enough to find out what happens if I let the needle get into the red.To let the needle drop, I have to turn the AC off. This isn't the best option now since we've been experiencing over a week of temperatures higher than 103.I also noticed that the temp needle will drop to normal within a couple of minutes if I turn on the heater.
I did open the bonnet when we returned from a trip and with the car running, checked to make sure both fans were running.

Our Air conditioner keeps on for about 5 minutes then cuts off. If we turn the car off and immediately back on it comes back on for another 5 minutes. we have taken it to the dealer twice at ca. 200 a pop and they say they have fixed it each time but they haven't.

I have a 2000 Subaru Outback with a little over 162,000 miles. About 3 years ago I had the head gaskets replaced. This past March the car started over heating while on the highway driving back to Boston from New Jersey. It has been doing this intermittently since then, and I have had two mechanics look at it.
The first mechanic, who is my beloved mechanic in Maine (where I am originally from), checked the sensors and relays. He even replaced the relays for free, and it still overheated on the way back from Maine to Boston. Needless to say I did not give him enough time to really look at my car to figure out the problem.
I then went to my back up mechanic in Boston, who kept the car for about 4 days. He said there are no leaks and the car did not actually over heat while with him. He had one of his guys drive the car home at night and back to the shop in traffic in the AM, and had it run for hours while on a lift, and on the ground. Still no overheating. However, he did say that the car was eating up coolant, which indicated to him that there might be a head gasket problem.
I was a little upset by this diagnosis because I had them replaced already, and also because I am getting married this summer so this obviously is not the right time to be buying a new car. I should mention that both mechanics looked at my car at the end of August. I have still been driving and watching the coolant.
The car is still randomly overheating but i tend to notice it happen more while in stop and go traffic and when I accelerate. The needle will go all the way up to red, stay there for a few seconds and then slowly creep down. This happened this morning, and I had checked the coolant yesterday and it was full! I checked it again at lunch time to see if it had used all the coolant during rush hour and it was still full. This chain of events seems to keep happening and I constantly check the coolant. Since August I have only had to fill it once. I have also noticed that when I open the radiator cap the coolant is not sitting level like I've been told it should. I've put a decent amount of work into the car and everything else runs perfectly.
Is it possible that this is a pumping or air bubble problem, and not a head gasket?

I have a 2008 Subaru Outback that is telling me that it is overheating, the gauge is showing me that the engine is as hot as it could possibly get. However, its not actually overheating. It happened after a 15 hour day of driving from Cali to Colorado on 2 lane highways. In the morning it took 6 tries to get started, just sounded like maybe there wasn't enough gas or something to get it going and if I fluttered the gas pedal the car threatened to quit on me. Since that moment the temperature gauge has been stuck on high, the check engine light is on, the cruise control is disabled and flashing on the dash, and the AC doesn't work. I have turned the car off several times since the incident and it starts up just fine so far but the gauge and lights are still on. ......

my friends mechanic is telling him his 2000 outback (2.5 4 cyl) has a blown head gasket. there is NO water leaking/seeping out from anywhere outside the motor AND there is NO water in the crankcase motor oil. the thermostat has been replaced. the cooling fans work. I'm inclined to say it's a plugged radiator. he is considering replacing the head gasket (to the tune of $1500+) on advice of his mechanic. is it possible to have a blown head gasket and not be leaking coolant?

Every once in a while in heavy traffic the engine overheats. I can't get out to check on the highway bit I suspect a an isn't on. I can drop the temp in the usual way of blasting the heat but I can also drop it precipitously by turning on the AC! It seems to stay down even if I turn the AC off - at least for a while. The radiator is new and it has plenty of fluid.

I have a 2011 Subaru Outback with 40000 miles. For the third time since I've had it (6 months), the engine suddenly gets very loud at highway speeds while I am on cruise control. The RPMs go up about 500 and this lasts for a few minutes before going away. What is going on?

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.

I brought my Outback to one mechanic due to overheating and a strange skipping feeling when accelerating. First mechanic said head gaskets needed to be replaced, I wasn't surprised since I have about 142k miles on it and it has been leaking oil, quoted between $1800 and $2000. I took it to another shop, recommended by a friend, and they agreed the gaskets needed to be replaced and there was also a misfire due to the spark plugs. This shop quoted me at $2200-2600 for the head gaskets, spark plugs, all wires and timing belt, all other engine gaskets, thermostat, engine oil and coolant. I still owe a good bit on this car (parents bought on the fly from a less than stellar used lot and now it is my problem), and my thinking is I do not want to bring on more debt by attempting to trade this one in and go for a new car. My question is, do I go with the second mechanic that wants to basically rebuild to top of my engine, or would I be ok limiting the repairs to the head gaskets and spark plugs?

This has been happening for the past 6 months or so. I recently had new ball joints, 4 wheel alignment, and 4 wheel balance. Even with this I'm noticing a very slight high frequency vibration at highway speeds. I noticed on one of the front wheels that a weight fell off, so this might explain the high speed vibration.
However - When I'm starting at 0mph, and accelerate to say 50mph for example, the car vibrates rather substantially as the speedometer moves from around 25mph to just past 30mph. After those speeds it goes away.
I've also noticed that it tends to be worse if I'm going up hill, which, according to the laws of physics, would tell me that going uphill would put more pressure on the front end, given it's heavier with the engine there. If I'm going downhill it vibrates much less.
When I drive I tend to not accelerate quickly, meaning, I don't 'punch' it, and accelerate gradually instead. If I'm driving on a level, well-paved road, and accelerate quicker than regular, the vibration seems to not be as heavy.
Any other tests for this? Struts, control arm, steering knuckle, drive shaft ?

While driving my 2000 Subaru Outback (197,000 miles) the speedometer, tachometer stopped working but the fuel and temp gauges were working fine. The transmission felt like it was slipping. When I used the brakes they were grabby, jerky and made a loud clunk. The engine began sputtering and I was barely able to keep it going as I tried to get home. At stop lights I had to put the car in neutral and rev the engine. We also noticed that while the engine was running the power windows were very slow to open and close and the turn signals and emergency flashers did not work at all. Now the car is in the driveway dead as a doornail and the key stuck in the ignition.
The battery is one year old and the alternator is the original. The fuel tank is 3/4 full. I bought the car new in 2000. What the problem could be?

My 2004 v8 with 100,000 miles is running hot. The fluids are all topped off. When I start it up she warms up normally in around 5-10 minutes and the water is 200 but as the oil temp comes up the water goes up as well. After 15 minutes of driving the oil is at 200-220 and the water is 230-245. the fans are coming on but so far no lights or warnings.
Is this the sign of emanate water pump failure? I think the thermostat is OK because for the first 5-10 minutes it runs normally. Putting the heater on get the temp down a little. I am thinking I should drive my truck and order the timing belt, water pump kit! Is it possible that the oil pump or system isn't functioning properly?

Misfire when driving just after warm up and either stoping or slowing down to turn feels like 2 cyls drop off .if turn of key then restart will run fine the rest of the day. changed the coil, ignitor, map sensor front o2 engine has a new timing belt and head gaskets, spark plugs were changed about 200 miles ago wires seem ok I ran a can of bg 44k through the fuel system not sure what to do now,, also it will not through a code of any kind bummer.
