Is it possible a radiator service was done at the same time? Subarus are notoriously tricky to "burp" when the coolant is changed and you may have air in your system. You'll want to take it back ASAP to be corrected lest you damage the head gasket or other parts of the engine.

This isn't directly related to your timing belt replacement, I don't think, but it's not unusual to have the cooling system service done at a time similar to the timing belt.

yo, yes it seems like air in the water, burps describe it well, sadly i did the belt myself and replaced the tensioner at the same time. Do you have a method of burping these radiators? cheers andy

I believe Subaru issued a TSB or something on the correct burping procedure to eliminate air from the cooling system. I think it involves slowly filling the radiator with the car on an uphill incline or jacked? My mechanic had access to it through his data subscription service, but I'm sure there's a way a DIY-er can get at that. Someone else might post details?

It's been a few years since I replaced the timing belt on my 1990 Legacy... I had to do the job twice, because I didn't know about the burping problem at first. I drove the car after the first replacement and a few miles later it promptly overheated. I was somehow able to make it back to where I replaced it. Not knowing about the burping problem, I assumed I might have missed something (or had a faulty thermostat) a did the job *again*... everything looked alright. The second time, I did take a very cautious approach to refilling the radiator. I pushed the front of the car up and down while refilling the coolant. This seemed to work as I had no further problems. If I remember correctly, there is a vent valve on the top left hand side of the radiator (on the other side from the refill)... this valve must be opened as it allows air to leave the system more effectively.
