I am looking to put stop leak into my jetta, and can sort of see the radiator, but am unable to find the radiator cap. It seems as though I am going to have to take off the whole front of the car to get to it...is this true? Please help - I am having no luck on online forums!

So do I put the stop leak into the overflow resevoir - or is this another plastic tank you are talking about?

doesnt have one, fill from header tank or disconnect top hose, drain some coolant and re-fill. may have issues with heating system

Your other respondents are quite correct. There is no radiator cap on that car per se. Access is entirely through the overflow tank unless, as one respondent noted, you remove the upper radiator hose.
As far as using stop leak goes, you certainly can use it, and if you are concerned that it may clog up your heater cores you can remove and plug the hoses to them while you are allowing the stop leak to do its work so that it is not circulated in the heater cores. Then, if the leak subsides, you can drain the system after a few days, reconnect the heater hoses and refill the system with a fresh antifreeze and water mix.
However, one thing to note here is that not only does your Jetta radiator not have a radiator cap, it also has plastic rather than metal reservoirs on the ends of the radiator itself. Most of the Golf, Jetta and old Rabbit radiators I have seen that developed leaks did so because the reservoirs cracked at the seam between the radiator core and the reservoir. With that kind of failure, the likelihood that the stop leak will work is considerably diminished.as the seam will continue to flex and reopen the gap due to vibration when you drive the car.
Jetta radiators are not terribly expensive, especially if you buy them from a third party vendor or a junk yard, and are not very difficult to change either. If it were me, and I was sure it was the radiator, I would probably just replace it.

It is on the plastic surge tank under the hoof. It is not on the radiator itself

it should be near the radiator. or somewhere else. actually, there might not be one. often time VW will omit the radiator cap. I think it has something to do with Hitler's legacy.
