more cooling question

[F_T_F]

so after replacing the HG and having a fun ol' time with a bad water pump, thermostat and radiator cap, i have yet another problem; i am loosing radiator fluid but i have no puddles i can jsut smell it after driving for a while and every couple of days i have to add more fluid. the smell is comming from around the turbo area, by the water outlet housing

did you fix your problem? If not you should get a cooling pressure tester and see if you loose any pressure.

I had the same problem and found out the Tstat housing wasthe culprit. It is a little warped so I put a little silicone silant and all is good now

Check your coolant lines to the turbo...might be a good idea to replace the hoses if they are old. There's also a small 90 deg hose under the waterneck to the hard line around the block.

I would pressure test it like mentioned above and pinpoint the source of the problem. Oh yeah, it would be a good idea to replace any old coolant hoses .

Mine did the same. Smelled like coolant but would never puddle up while sitting.
Turns out (like jdub said) the coolant lines to the turbo would seep coolant at the ends.

I'm betting turbo coolant lines as well. You can't see it as easily because it instantly burns off the exhaust manifold as it drips.

You should see it if one of the turbo coolant lines ruptures with a hot motor...it's pretty spectacular.
