2006 wrx overheats going slow but not at speed

I don't think there's any reason to suspect a head gasket right off the bat like that. The first thing that comes to mind is the electric cooling fans. They are on the car specifically to keep it ...

High-mileage transmission with no known oil changes. Safe to change fluid now?

If this were my vehicle, I would change the transmission fluid and filter. There is a baseless school of thought, more like an "old wives tale" that you will just cause damage by changing ...

1997 Subaru WRX STI Type R - Strange and occasional turbo lag

Too long for comment, but I suspect wastegate linkage or door not closing fully due to distortion from heat (it's really hot around there). You could try and get it hot enough to duplicate the ...

2006 wrx overheats going slow but not at speed

Cools at speed, but not at slow vehicle speed. Definitely an engine cooling fan issue. It's either the fan itself or the sending units that tell the fan when to come on. Best bet is to pick up a ...

Intermittent ticking noise in 2015 Subaru WRX

Given that the issue vanishes "immediately" upon pressing the clutch, I would guess that the problem lies somewhere in the transmission or its linkages. The already mentioned throwout bearing is a ...

2002 WRX Impreza overheats despite cooling system overhaul

The cooling fan and water pump are usual suspects that you did not mention yet. A bad water pump will overheat an engine really quickly because there is insufficient coolant flow, a broken cooling fan ...

Is there a standard for how much oil should be added after replacing the high-pressure hose and accumulator/drier?

Checking the pg. 28 of service manual suggests that you don't need to add any oil for replacing the dryer itself - just the 1ml for the replacing the hose: Replacement parts Amount of oil ...

RPM shoots up at full throttle Slipping Clutch?

When you get your foot off the clutch, there is(or rather said there should be) a fixed connection between your engine and your wheels. If you see a rise in rpm without the car accelerating, there is ...

Steering wheel sometimes centered, sometimes not?

One of the bearings at the top of the struts may be worn. This could be causing the coil spring to rotate slightly under hard cornering. This could then cause a slight pulling in one direction, ...

How do I replace the side mirror glass in a 2004 WRX?

The mirror glass is fixed by adhesive pads, which usually come with the replacement glass. Use a heat gun on the old mirror glass to soften the glue, and gently pull it out. Wear gloves, in case of ...

02 WRX loss of power/boost

I would guess you have a boost leak. Have the car smoke tested to check for leaks in the intake system (bring it to a shop that knows Subarus, there's a lot of nuance to look for). If it's been ...

2005 Subaru Impreza WRX P1446 Fuel Tank Sensor Control Valve Circuit Low

"Circuit Low" immediately sounds like a voltage problem. I would begin by checking continuity with a multimeter from the sensor to your ecm (engine control module) and finding what voltages ...

Subaru Forester XT overheating

It seems to me the system is running as it should. The only thing you could do is to have the tune changed to start the fans sooner (at a lower temp). As soon as the fans start, the temp goes down ... ...

Strange liquid sloshing noise from gearbox / transmission

Took the car in for service, and @SteveRacer was right. It was the air con - they did a full flush and recharge (it was the 120,000 mile service so it was about time anyway) and the problem has ...

Loss of coolant issue

The coolant must be going somewhere. If you don't see any external leaks, the leak must be an internal leak. Head gasket would be the usual suspect here. Perhaps the leak is so small that you just don'...

Intermittent ticking noise in 2015 Subaru WRX

Why is oil on my throttle body hose?

I'll start off by saying that this may not be an answer, but rather a methodology for diagnosis. On that Subaru, the turbo should be to the right hand side of the engine. You have oil pick up and ...
