Question about Subaru Legacy

1 Answer

I have 1995 Subaru legacy GT with the 2 litre Boxer 2-stage twin turbo engine. My garage said my car needs a 'knock sensor'. I have a second non-running car the same and I want to get the knock sensor off this one to save cash. My garage mechanic said I need to remove the 'inter-cooler' (2nd radiator on top of engine block beneath bonnet air scoop?) to reach it - but how do i get this thing off??? Thanks!!!

    Thanks, Are the main bolts the ones I can see from the top or are there any hidden? Just seems to be spring clips on the hoses and a screw up clip on the main big central hose about 4 inches long. I'll

    get back on it asap and let you know how I get on!

Hi! There are hoses that attaches to the intercooler radiator. Usually it has only metal fittings that can be loosen by using a screwdriver. Remove those hoses and remove the bolts that attaches the turbo intercooler. By then you can have access to the sensor. Repeat in reverse order on putting up things together again. Hope this helps and have a good one!

Engine knocking on my Subaru legacy 2 litre twin turbo. Knocks all the time, but worse when revving! Any ideas what this could be??? Thx

By your description it sounds like a rod or crank bearing has gone bad. This is a VERY serious issue and you should have it looked at immediately by a good mechanic. If either of these is the issue, the repair is expensive and time consuming, just so you know in advance. But if it is not addressed, it will result in the destruction of the lower half of your engine. There is no good way to predict when, either, but it is not likely to last more than a few hundred miles.

Hi, I have a '95 2L Legacy Boxer 2 stage twin Turbo. When i'm driving and the engines reving at ot just above 2000 rpm I'm getting a dip in power for a moment before it picks up again. I haven't noticed...

the 1st thing that needs to be done here is to find what fault code is turning on the check engine light, this information is absolutely crucial to making an accurate diagnosis of this problem, guessing is not an option as each part that could cause this is very hard to replace and very expensive, so get the the engine control system tested, this is what is called OBD 1 electronic engine control and requires a Subaru scanner to read code.

Yes they will bolt in. Make sure you have the sensors matched. You might have to do some playing with the computer to make it all work properly. Good luck and have a great day.

Fault code 45- how do i repair it?

The code 45 in a later model is for the AWD control module causing harsh shifts. On a 2000 model the warranty per recall is 8 years and 100,000 miles. For your model you can try calling a dealer about recalls.

Sudden loss of power when travelling for a few seconds,

The spark plugs for your vehicle are located 2 on each side of the engine. They are a little difficult to get to because they are right by the frame. Follow the plug wires from the coil and you should have no problem finding them. Hope this helps Good luck.
