If it's leaking again from the pipe then try some blue goo, i take it you used a new o-ring???

You dont have to remove the water pump to replace the oring. All you have to do is undo the 19mm bell housing bolt around 3 turns. There is a clamp held there, or if it have been relplaced before there probabaly inst one there anymore. (most people dont put them back). Then undo the 13mm bolt to the by pass hose directly under the exhaust manifold at about cylinder2 (sometimes there are two bolts, the other at around cylinder 5). Then get a large pry par and leaver on the bell housing where you undid the bolt and leaver back the bypass pipe. You only have to leaver it back about 50mm. Then replace your oring and put a bit of sealant around the oring and put it back in (careful not to pinch the oring on the housing pushing it back in). HINT: have car cold and radiator cap on, then you will only loose about 1/2 litre coolant, if you undo radiator cap you loose the whol lot!!
Hope this helps!
I'm a ford tech and have done about 300 of them this way!



if had a leak like that and payed someone to fix it, i'd be a bit p****d off if the coolent wasn't replaced. i'd also be p****d if some half a*** fool put sealer all over the seal.

i've done hundreds of them and none of them needed sealer on the o ring.
if the pipe is rusted, it needs replacing anyway.

Did you put oil/silicone on the o-ring before install?

I take it all the pipes are bolted securely back to the engine as well?
