Default coolant leak '04 TS

at first it looked like it was coming from the block, looks more like where the lower hose connects to the block - that connection also looks like the thermostat housing

gonna pull it later today, would be nice to know what im getting into beforehand

pics or manuals appreciated

last coolant change was 2 months/5k ago - system was flushed with 50/50 water and vinegar for a few min, then rinsed 3x

refilled with peak global and subaru conditioner

to me the recent coolant flush and change is incidental and the leak is likely due to the colder weather, associated heat cycles, and 90k mi

started leaking yesterday, its a steady drip and leaves a big puddle... arrrrrrrrg

the thermostat housing seems an unlikely place to spring a leak

can anyone confirm the lower radiator hose on a N/A 2.5 goes to the thermostat??

It's possible you could a leaking water pump seal.

Yeah, water pump is right above it. I'd get it pressure tested and see where the water comes out.

Default my subie is bleeding!

didnt try working on it in the dark..

leak is much worse today, have topped it off 2x now - about half a gallon each time

agre, sounds like it needs a new water pump - 90k replace the timing belt with it?

Yes,

Also replace the thermostat and timing belt tensioner.

Duncan, think the flush and use of non-subaru coolant helped the seal fail?

Highly doubt it.

As mentioned, if you pull the pump to change it, might as well do belts (AC, PS & Timing) and timing belt tensioner as they all have to come off to do the water pump.

Getting it pressure tested first is a good idea so you know first. It could be a cracked thermostat housing, water pump shaft seal, water pump O-ring/gasket, or even a HG leak.

As to replacement water pumps, I use brand new Bosch pumps with great success and very inexpensive compared to OEM. Do a new thermostat as well.

Default estimate

$450 parts, $550 labor for water pump, belt, tensioner, thermostat, gaskets

ouch, a bit higher than expected, and absolutely cant pay for that now

would be nice if i could replace only the pump and defer the rest, from what i can tell, thats not a good idea

looks like ill be riding my bike a lot until i can afford all the parts

you shouldn't need a new tensioner, did they quote that before even looking at it? get a quote somewhere else.

Default Paul Bros. Subaru, Herndon, VA

They did the pressure test while i waited, determined the water pump failed and gave me a reasonable quote of $550 just to replace the pump, another $100 to have the timing belt replaced

Much to their credit, although very busy, they did eval while i waited and in under 30 min and didnt try to rape me for extra parts...

i purchased a water pump, belt, thermostat and gaskets from them for around $200

havent changed a timing belt on a subie since the late 80's

Default fixed

6 hrs to replace the water pump and timing belt!

compressing the tensioner proved to be the greatest challenge.

thanks to jonniebravo for allowing me to work in his garage (and did much of the work himself!)
