Have small puddles of coolant under front pass. side when parked. 88k miles. on 2004 Land Rover Range Rover

Trying to avoid paying $200 for diagnosis at shop to tell me its a $10 hose. Is this common with this truck to leak and how likely is it that it's the radiator? No crack in reservoir or top hoses visible. Also, will it harm the system if I use K-Seal to stop radiator leak if that's what it is? Thanks for any advice.

The leak could be from many places you will need to run the engine get it hot, switch it off and look for the leak with a flash light and maybe a small mirror. The way an automotive shop would locate the leak is by removing the radiator cap and attaching an adapter that screws on in place of the radiator cap. Something that looks like a bicycle pump with a pressure gauge attached to it is used to "pump up" pressure to simulate pressure generated when the cooling system is at operating temperature, the leak is then found sometimes it is obviously leaking from a coolant hose or cracked housing, failed gasket or water pump, sometimes the engines cooling system needs to be inspected from below or inspected using a mirror and flash light. If the coolant loss is still evasive dye can be added to the cooling system that may indicate the source of the leak. A mysterious coolant loss may even be a sign of a head gasket that is not sealing well. Barsleak or Allumaseal won't seal a bad coolant hose but works well on radiator leaks.
Thank you! Very helpful.
