Leaking coolant possibilties

Featured Replies

I replaced the gasket and silconed it with water pump sealer along with the tube that goes into it, and my cars still leaking coolant. Its dripping down onto the exhaust, its just a drip....drip.... and it turns into a decent puddle in a few minutes. i cant figure it out, the weep hole on the top is bone dry and the pump has no play in the shaft. Im pretty sure i got the gasket on perfect. Any hoses in that area that could leak slow like that

uhg seriously, i got the surface as clean as possible, and put the silicone sealer stuff on the places it looked iffy if it would seal right. Did that screw me over? Can the water pump go out without taking the timing belt and stuff out??

Have you checked other stuff? Heater core hoses, intake gaskets, etc?

 

For the record I install all my water pumps with RTV only. I don't use a gasket because I almost always get used pumps due to the vast ocean of soobs I have to pull them from (I always seem to find the car that *just* had one replaced before it was wrecked). Thus I never have the gaskets handy.

im looking, im not seeing any hoses, do the manifold gasket leak externally also? i may check that out, like can it drip down to the exhaust? its right on the center, a little off to the drivers side abit, not centerd.

how is the coolant getting from the pump to the exhaust, i'm confused the exhaust goes out the back the pump is in the front are you sure it isn't a hose, do ea82's have that steel inputline with the oring that seals it?

There are holes in each head near the spark plug where water (or coolant) can drain away. These holes drain right near the exhaust....

you know the front exhaust manifold/pipe? It runs right under the timing belts and all that

 

Yes it has that steel input line, i smothed it in that gasket RTV stuff to make sure it sealed, wich from what i can tell it is. What are these holes ur talkin about?? Like freeze plugs?

yes but the pump is in front not on top, am i missing somthing?

 

edit: oh i'm tired night thanks for the lesson

yea and the exhaust is in the front, right under it, and the coolant is dripping down the block from somewhere onto the exhaust pipe that runs in front of the oil pan

No - there are holes cast right into the heads - right near each of the spark plugs to drain water away from the plugs. They go all the way through the head from top to bottom.

why would they drain coolant tho? Im going to tighten the water pump bolts a little more, i went fairly light on all the bolts, afraid to squish the gasket. but im not gonna wrench on them and snap the bolts, lol, thad be stupid

i under stand that there are holes cast into the heads, prospeeder answerd my question i don't have any turbo experance i forgot the uppipe goes infront of the engine under the oil pump

yea but still, if you know any odd coolant hoses, or places coolant can just drip drip drip down lemmie know, so i can check em tomarrow. Other than whats been listed

Because the coolant runs TROUGH the manifold - so if you have bad manifold gaskets, they can drain into the plug areas, and down through the drain holes directly onto the exhaust.

 

There's also a few throttle body coolant hoses in front of the manifold that could be leaking. They provide coolant to the throttle body to warm it.

oh arlight, thanks, ill check that out, make sure those manifold gaskets arnt leaking. And any of those hoses. Im really hoping its anything BUT the water pump, lol

intake gaskets not leaking. I stareted it and the fan blew a bunch of coolant out and then it stopped, im not even losing coolant from what i can tell. could it be coolant in little areas getting nocked out when i start the motor and dripping down? cause alot of coolant went everywhere when i took the water pump off to do the seal. Im still looking like crazy for leak spots, but im finding nothing

uh if your fan is throwing coolant have you checked your radiator? it's becoming suspect in my book

  • Author

I checked the radiator, no coolant coming out of it. I got a new water pump for 30 bucks. And then a hose under the intake manifold decided to spring a pinhole leak and spray coolant everywhere. LOL gosh you people arnt kidding when you say Subarus always leak somthing

Not *always*, but 20 years takes it's toll for sure. If you reseal them properly with quality gaskets and such they last a long time before they start leaking again.
