I removed the cylinder heads and had them cleaned, rebuilt and shaved. After reinstalling everything, I find that the engine will not turn over. It was running prior to the repairs. I believe I might not have aligned the valves correctly. So my question is how to I get the timing gears realigned?

My dealer is telling me that at 105k, the timing belt needs to be replaced. They said that when they replace the belt, they replace the belt and the tensioner but that is all. I have a mechanic who will replace the belt cheaper than the dealer but he says that I should also replace the water pump. The dealer when I asked said that the water pump on subarus is usually good and it's mostly on GMs that the water pump needs replacing then. Who is right here?

Thanks!

Hello,

Well, here is how I do it.

If the timing belt needs replacing and the Water Pump is run by it, I won't do the job unless I replace the water pump. There is no sense in doing one and then possibly having to pay the same labor again to have the other done with a few of months.

This is how I look at the water pump and replacing the timing belt. The timing belt has stretched over the years and mileage, which in turn reduces the stress and tension on the old water pump. So, when new belt is put on it will create more stress and tension on the old water pump which will cause it to fail within about 6 months or less.

So, I feel the dealer is trying to make some extra money by only doing the belt and hoping within the next couple months or so you will need to water pump done.

Also I would make sure that all timing components that can be replaced are.

We had the timing belt replaced at 55000 miles while having warranty work done on our car. When should the timing belt be replaced again on our 2003 Subaru Forester? We are at 110000 miles. It was replaced at 55000 miles.

Was it dealer oem belt? Supposed to be every 100k or 100 months. You are told to inspect it at shorter periods so you could have it inspected? That engine is severely damaged when belt breaks. I would change it sooner than later.

Car stopped functioning and was frozen a 2,000 RPMs. All warning lights came on and it will not restart. I am hoping that based on the video provided, someone might be able to let me know if it sounds like the timing belt may have called it quits. Had some overheating issues with it last week as well (maybe a water pump failure?). The car broke down right around the corner from home and would be a long tow to get it to a mechanic. Trying to determine if it would be worth it to get it brought in to town, or if I am likely to just get news that the car is scrap at this point.

Depending on what engine this is, it sounds like it is a timing belt. If you have a single overhead cam (SOHC) engine this is a non interference engine and if the timing belt broke then the engine will just spin over and not start.

However, if this is a dual overhead cam engine then it would have locked up if the timing belt broke. So if it is turning over then it is not the timing belt.

Here is a guide that will help with an engine that is not starting:

Also, here is a guide that will help with a timing belt repair.

FYI - I am only showing a DOHC engine for the Forester so I suspect you have anther issue then the timing belt. Based on this, let's run through the guide above and this one as well to figure out what we have and do not in order to get the engine to start. This will help you check for codes.

How urgent is it to replace the camshaft drive belt (which I assume is the "timing belt") at 105,000 miles. If I must do it, should I also have the water pump replaced? The car runs ok.

It is critical to change it, you don't want to let it stretch too much as it will cause the engine to loose power and will potentially break causing severe engine damage in most cases. I recommend buying replacement kit from non-Subaru dealers if u can't afford to pay over $600 for the OEM parts, not the mention the labor. I bought the kit from E Bay at CNS Auto Parts for around $200. The kit includes all pulleys and the tensor pulley which must be changed along with the belt, I highly recommend it, and if u have never changed the water pump then yes change it too.

The front pulley should fall off it sits in the gear with a locating pin only, with the bold off it should just pull off by hand, of a worst a gentle pry with a lever.
