coolant leak

Hi all,

I noticed a slight leak of what looks like anti freeze/coolant. Dripping from somewhere under roughlyu where the radiator is, difficult to see because dark and rainy.

I checked the header tank and it looks OK, so not a major leak.

I have however also noticed (and it might just be me being paranoid) a slight downturn in power and pull when acceleratring.

I am wondering if it might be something to do with the turbo or intercooler.

I have a rad muff fitted but it does not cover in front of the interccoler mini radiator, I plan to remove that tomorrow.

can anyone offer any advice on what I might check?

I confess to knowing a big fat zero about turbos, and I dont even know what the intercooler mini radiator is for or what it has in it.

Help please>?

The intercooler cools the air from the turbo before it goes in the motor and has nothing to do with cooling the engine its self. Check the rad,hose,[top and bottom] water pump.

It'll be a case of checking the rad under favourable conditions to see if you have a leak of some kind, until then it's guess work. If it is a problem with the rad, it won't effect power though, so that'll be a seperate issue.

The Intercooler ( the small rad ) is designed to cool the air from the turbo before it reaches the cylinders, cooler air = better response = better mpg and a happier engine.

The air comes from the vent on your NS wing > Airfilter > Turbo > Intercooler > Inlet manifold > Engine.

Can you elaborate on the loss of power more?

The 19J which was the before the 200Tdi ( which you have ) had no intercooler and suffered problems,not just to do with no intercooler, but it was a contributing factor.

thanks for the replies, found a leak on the radiator, will try to sela with radweld, or failing that change the rad - so that is a separate problem

regarding the power loss, i am not sure if it is just me but it just doesnt quite feel like it has the pull it used to, although I can hit 65-70 without any probs

I would just liek to know for my own benefit if there is any way I can tell if the turbo is working properly as it is an area I dont really understand

Many thanks in anticipation
