Is my radiator screwed?
Hey guys, I've posted this on Audizine with not much luck, my car has been out of commission now for a while now because I can't figure this out, can you guys please help me!
Thanks guys.
This all happened after I did my timing belt.
My car is leaking coolant, not sure if i forgot a hose, or if my radiator is bad. Let me know what you guys think it is. Thanks guys.
Here is the general idea of the leak

Here is the leak with the bumper off so you can see it better

It's unlikely your radiator is screwed if it wasn't screwed before the TB job. I guess anything is possible and you poked the radiator with a screwdriver or something, but I say it's unlikely.
Far more likely is you have a leaking connector...either at the top of the radiator or bottom...did you replace the O-rings on the connectors? Same with the O-rings on the temp sensor if you replaced it while you were doing the TB job. Check all your quick-disconnect coolant fittings.
One other thing, on my 2K4.2 when I was doing the coolant transfer pipe Bufkin Engineering billet aluminum replacement I ended up with a leak from the upper radiator hose where the hose from the expansion tank gozinta the upper radiator hose. The ****-ant OEM spring clamp wasn't tight enough...had to go with a worm drive clamp.
Soooo, check all your spring clamps...

Which connectors are we talking about? I thought there were only 2. I think the coolant leak is coming from the bottom right and I don't thing anything plugs in there. Do you have any pics for reference? Thanks mate

What is your engine and year ? V6 2.8, 3.0, 2.8 V8 4.2, 1.9TDI, 2.5 TDI, 1.8T ?
On the right side (standing in front of the car) at least on my car 2.8 below is a screw that is used to drain the coolant from the radiator, check that area and see if the screw is lose or broken
on the one of the photos looks like it shows is leaking from that area ..
other possibility it is cracked radiator, looking again at one of the photos maybe I might be wrong but what fluid do you use , water, or coolant fluid ?
if you are in colder climate and used water it is possible that if you didn't drive your car for some period of time, the water froze and expended damaging the radiator , again this is my assumption since you post very little about your car and where you live , we are just guessing here ...
if you find that there are no leaking pipes, and the screw is tight, then you need to replace radiator
