My car smells like its overheating but not steaming. Fans are not coming on. tested it last night and after about 30 min of running and reving it up, it blew a little steam out radiator cap. I am not getting warning lights on the dash at all. I tested all fuses and relays to the fans. could it be thermostat? why would fans not work?

First you may want to use an external infrared thermometer. Aim it at the engine block and check the temperature. This will prove if the engine is overheating or not. If the engine is not warm enough the fan will not come on.

Fans not coming on

The Engine cooling fan is controlled by the ECM. The ECM uses an Engine Coolant Temperature Sensor signal to decide when to turn the fan on and off. I the coolant level is low the sensor will not be able to read the correct temperature. So first thing to do would be to check the coolant level. If the coolant level is low, find out why and make the necessary repairs.

I replaced my converters and the oxygen sensor but my check engine light is still on. I took it and the code was P0037 bank 1, sensor 2 low voltage ? It is a 2003 Subaru Outback with 2.5.

2001 Subaru Outback

Changed my oil Wednesday and transmission. Car was running not that great before hand. Filled up oil with 10w30 synthetic and added a bottle of Lucas oil stabilizer. (I always use to add 10w30). Filled transmission with DEX3 5 quarts. (Over filled it by a quart) ever since I changed fluids when I start the car it makes a ticking noise. Once it warms up it gets lower.

2001 Subaru ForesterSo, one day I went to check my oil and coolant and they were both low. So I used a different car to go get the products to top them up, using both permite (that’s what last owner used) but I wasn’t sure what oil they used. There was 5-30 but there was also 5-40 which recommended using if i was putting 5-30 in it. So I put the 5-40 one in anyways that’s not the point of the story.

The point is afterwards I went to the petrol station to get some fuel and as I was stopped at the lights on my way out white smoke just came out of my exhaust. As soon as the light turned green I took off and parked to see what was going on, and it stopped? But now every time I drive my car and stop at a red light or something it smokes. At first not so much but as I’m sitting there idling it gets worse. It does stop after I’ve stopped like 4 times (for example on my way back from the shops I stopped my car in the driveway to see the smoke and it didn’t smoke at all…its soo weird, suggestions?


White Smoke

White smoke is an indication of a engine coolant being burned in the engine. This can be caused by a blown head gasket or leaking intake manifold gasket.

Blue Smoke

Blue smoke is created by the vehicles engine oil entering a cylinder and being burned along with the Air/Fuel mixture. A small amount of oil leaking into a cylinder will create blue smoke out the tailpipe. Blue smoke is more often and issue in older or higher mileage vehicles.

Sometimes using a thicker oil can help, but in most cases replacing the failed gaskets and seals is the best way to insure the issue is fixed.

Black Smoke

Vehicles before 1996 will sometimes emit black exhaust smoke during the first start up of the day, this is normal as long as it clears up once warm. On vehicles built after 1996 , Black exhaust smoke is not normal. This is an indication that the engine is not burning the fuel efficiently and or the fuel injection system is trying to force to much fuel through the engine.
Possible causes range from a failed O2 Sensor, Injector Stuck open, or failing MAF Sensor. Some times a simple tune up is all that is needed.

1993 Subaru LegacyCan I put some kind of brake fluid sealer to stop it from leaking?


Brake Fluid Sealer

My response is NO. The brake system utilizes extreme pressures to operate. The brake fluid leak needs to be properly repaired in order for the system to function correctly. The basic principle of a brake system is the free movement of fluid through the brake lines. Any kind of brake fluid sealer would ruin the entire system and cause more damage.

How to locate a brake fluid leak

First of all park on a flat clean surface or place clean cardboard under the vehicle.Top off the brake fluid reservoir. Pump the brake pedal a few times while someone looks under the car. Hence you may notice a hissing noise. This is the fluid escaping. Look on the ground and note a puddle. If none are found maybe look at the insides of your tires. Finally this will give you an idea of the location of the leak. In conclusion brake fluid leaks are generally affordable to fix.

2002 Subaru ForesterMy Subaru’s turbo is only active in colder weather. I live in Southern Africa where it rarely gets very cold. This car has been imported from Japan. The highest octane fuel we can get here is 95 octane. Can anybody help me with some idea where to start looking for the problem?


No Recalls or Technical Service Bulletins were found when searching for Turbo related issues.

That is odd since the turbo works off the exhaust system. The Turbocharger may be going out.

Turbo Charger Replacement

Removal & Installation

  1. Before servicing the vehicle.
  2. Disconnect the negative battery cable.
  3. Remove the center exhaust pipe.
  4. Separate the turbocharger joint pipe from the turbocharger.
  5. Disconnect the engine coolant hose from the coolant filler tank.
  6. Loosen the clamp that attaches the turbocharger to the intake duct.
  7. Remove the oil pipe-to-turbocharger bolt and remove the oil pipe from the turbocharger.
  8. Remove the turbocharger bracket and disconnect the oil outlet hose from the pipe.
  9. Remove the turbocharger.

To install:

  1. Installation is the reverse of removal, please note the following torque specs:
    1. Turbocharger-to-intake duct: 2 ft. lbs. (2 Nm).
    2. Oil pipe-to-turbocharger: 11 ft. lbs. (16 Nm).
    3. Joint pipe-to-turbocharger using a new gasket: 22 ft. lbs. (30 Nm).
    4. Turbocharger bracket: 24 ft. lbs. (33 Nm).

1998 Subaru ForesterMy car randomly misses and bogs down and at red lights it sometimes revs up and lurches forward when holding the brake down. I have put a new fuel pump and filter, New alternator, plugs and wires, and a new coil. The transmission sometimes shifts hard but has never slipped or anything. The car has 263k miles.



This sounds like a vacuum leak. Of course if the check engine light is on, the first thing to do would be to pull the engine trouble codes and post them below.

oil consumption 2015 Subaru ForesterDealer replaced engine block after 11 months of failed ‘oil consumption tests’.
At my first 1200 mile oil check, the new block is half a quart low.
Should I be concerned again???


No. But I would definitely keep an eye on it. It is normal for some oil to be consumed or burned during break in  as it gives time for the rings to seat properly. A half quart would bring the oil level to the middle of the safe zone on the dipstick when checking your oil level. It is your responsibility to check your oil level often. So do just that, check it often. If you notice continued loss in large amounts, then be concerned.

Per Subaru 1 Qt per 1K is acceptable(2009)

Porsche this is (typically) 1.5lts per 1000kms

Toyota this is (typically) 1.0lts per 1500kms

“acceptable” means: We aren’t fixing anything unless it is worse than that.

Subaru Outback
In my Subaru Outback I have to remove the tail light fuse each night or it will drain the battery. How can I fix this..

This is the outcome of a problem with the tail lamp relay which is not unusual for the Subaru Outback. The relay gets stuck, even though the key is out, and allows the battery to power the tail lights and parking lights till eventually the battery discharges completely.

Subaru Outback Problems

Complaints of check engine light on, cruise control blinking, and no acceleration.
The car tends to loose power and may occur while driving at highway speeds. The most common fix for this would be to replace the pedal assembly including sensors.
