So I recently changed the timing belt, water pump, and all that jazz, also pulled the motor to replace the oil pan.

Now I have a coolant leak, I can't seem to locate the source.

First I found out one of my heater hoses had a tiny hole in it, so I made new one, now that area seems to be leak free.

But it's still leaking coolant.

This is where its dripping from, the boot on the transmission that holds the clutch slave cylinder:



which is weird, cause I'm positive there isn't supposed to be coolant there. I check the hose in the back of the block, that doesn't seem to be leaking, can't seem to figure this out. Could it actually be leaking out of that boot? that's the only area that seems to be affected by this.

Oh and it's not like a drip drip leak, its more like the motor is pissing out the coolant.

 

Ok its not the boot.

Had my dad pour in water while I check to see where its coming from, somewhere back of the block, but all teh hoses are dry, ahhh

 

If all hoses are dry and okay, and it's coming from the back of the engine...head gasket? Freeze plug?

 

I really doubt it's the head gasket, it's only leaking from that one spot.

I didn't think of the plug, thanks for the idea, I'm going to go check that.

 

Check the hoses that feed the oil cooler.

If the leak started after you did the pump, are you sure it's not the pump?

 

Only leaking from the back, wouldn't it leak near the pump?

I'm waiting for all the water to dry to to check again.

 

Dreded water plug. Or outlet gasket.

 

Yes, but if it started leaking right after a pump job, kinda seems fishy does it not?

Maybe it's running to the back, idk?

 

I'm with Flounder on this, but I've been thinking for an hour on it, and have no clue how this could happen as it would require the water to quite literally go uphill.

 

Fixed it.

Feel retarded, turns out the bottom bolt was loose, which was super hard to get to haha.

Thanks for all the help.

 

Bottom bolt for the rear outlet?

 

Yeah. Not sure when I loosened it tho, especially since its all the way in the back. Hopefully it didn't do it by itself. haha

 

EDIT: Wrong thread.

 

Sorry for bumping an old thread, but I have the same exact problem, and didnt want to make a new thread lol.. So which rear outlet are you speaking off? Maybe I can fix it the same way as you did

 

look where heater hoses are going to the back of head. you have a leak there.

 

ugh that is one tight fit. Any tips on how to make the job easier?

 

remove the engine. It takes roughly 40 minutes.

 

lol..thx for the tip
