Hi.

I have this oily stain front of the radiator....dunno what is the problem, there seems to be some metal pipes there attached to radiator...they could be the ones leaking?

Anyone got an idea? Please see picture.

Thanks

that seems to be the aircon unit

others will advise you more detail I'm sure

are the power steering ( long ) cooler pipes at the rear of the radiator weeping through ?

Thanks.

Thats more likely. I was worried it might be the transmission lines.

Is the power steering fluid cooled at the rad?

I went again and had a look, all i can see is some pipes connected to aircon compressor.

But surely if they leak my aircon shoud be dead by now.and its working fine???

Had a look at the U shaped PAS steering lines In front of rad and they are not leaking

a mechanic dropped a little oil or summat when servicing her or maybe some sad body fluids of a now long gone huge insect !

I did clean the area before using loads of brake cleaner only to find out that the leak has returned, Its coming from the pipes that are clamped  on rad and going to the aircon dryer.

I would say it's aircon lubricant oil

OMG looking at the engine compartment today, such a rare occurrence, of course the pas cooler pipes are in front of the aircon unit

I think its the aircon dryer pipes where they join a union block , i suppose some o.ring there has failed
