It will cost $1500 - $2000 to replace the timing belt, water pump, head gasket, and front crank seals.What other long-term problems does this car typically have?l am trying to decide between repairing the car or trading it in on something else.

You should be good for another 100k miles. The timing belt absolutely must be replaced soon or you will be facing replacing the entire engine if it happens to break.

Typically it is a good idea to replace the water pump after 100k - might as well do it while the timing belt is off.

Unless you know the head gasket and seals are bad, you might wish to hold off on those for a while.

First of all, where do you live? These prices are WAY too high. Is your head gasket bad? The timing belt can wait until 125K-130K..no problem. To answer your question, head gaskets are the ONLY things that go bad on these cars. If you change those...the car will last forever! Do not throw the baby out with the bathwater. Contact me if you have more questions.

If you do the work that you describe, you should be good for another 70000+ miles. The car does not really have any specific or unique problems. Another issue that may arise is replacing the catalytic converter. That can be a bit costly. Doing or not doing the work should be based on how long you think you would like to keep this vehicle. Given some of the programs available on new, l would consider researching a purchase before you decide to do the work.

first off, timing belt, water pump and front main seal should cost around $500. make sure this is the case for the price quote you are getting.

why is the HG being changed? its not a wear item that needs to be replace. you only replace it if its been breached because of overheating, etc

lastly, 2.5L non turbo subaru engines are very inexpensive. you should consider repacing the entire motor rather than paying $1000-$1500 for a head gasket replacement.
