Can I isolate a leaking radiator?
If work is being done to your system to correct the leak, then you’ll need to isolate the radiator. To do this, turn the valve clockwise as far as it will go. Once both valves are closed, the radiator is completely isolated and any repair work can begin.

Radiator repair costs aren’t terribly high in the grand scheme of things, so expect to pay between $100 and $500 or an average of $350. Simple fixes such as bleeding a radiator only cost around $100, but a complete pipe repair in a hard-to-reach area could hike up the cost.

However, if this doesn’t solve the problem and the leak persists, you can perform the following bit of maintenance –
How do you spring a leak in a radiator?
The two places you can spring a leak will either be the radiator panels themselves or the radiator valves at the end of the radiator.
