Subaru Turbo GL 10 quit on the road

[idosubaru]

Old gen you line the marks up 180 degrees off. You can install one belt, rotate, install second belt or just install one side with timing mark pointing up at 12 noon and the other side at 6am pointing down and no need to rotate.

(Newer subarus aren’t like that just for reference.)

 

Best to replace all the pulleys and tensioners. You can also use a needle fitting and squirt a little grease under the face seal if the pulleys, that’s the only failure mode. The bearings don’t fail they run out of grease and then overheat and fail. Keep them full of grease and they last forever.

 

The water pumps do fail sometimes, that Long arm sticking out for the pulley exaggerates lateral forces and wear in the shaft/seal,bearings.

 

People often get the distributor timing off installing it as you’ve done if you have more issues check that

 

Thise Turbo engines don’t handle age, overheating or poor maintenance well. Headgaskets are likely leaking or the heads are cracked. If you drop the exhaust manifold you can find cracks or leaks.

 

Occasionally the intake manifold gasket can leak which causes coolant to seep into the intake manifold and use coolant. But consider yourself lucky if that’s all it is at this point.

 

If the engine wasn’t abused - meaning overheated or run low on oil - they respond well to a good reseal and can be reliable drivers. But turbos have a lot more failure and maintenance points to get there.

 

Get the FSM, it’s way more helpful. We had a free copy loaded digitally on subaruxt.com if it’s still available but I think it may not be.
