To fix a leak on a radiator hose of a VW Golf MK3 GTI, first ensure the engine is cool and relieve any pressure in the cooling system. Locate the leak and inspect the hose for cracks or loose connections. If the hose is damaged, replace it with a new one, securing it with hose clamps. If the leak is minor, you can use a hose repair tape or a temporary sealant, but a full replacement is recommended for long-term reliability.
The thermostat for this car is located in the water pump housing from the lower radiator hose.
You can find the thermostat in your VW on the front of the engine. You can follow the bottom radiator hose directly to the thermostat housing.
Coolant is drained from the system by disconnecting the lower radiator hose. There is no drain plug as such. SD

not an expert but might be good start for you. Follow the hose which leads from the bottom of the radiator to the engine. There should be a a plastic manifold fitting thing. That's the thermostat housing.

Yes, it is a Golf but VW stopped calling it the "VW Golf... GTI". Just as VW didn't call the R32 a Golf (although it is based on the VW Golf and has the same shape and many common components).
The thermostat is located on the front right side of the car. It is underneath where the lower radiator hose is attached to the engine.
Doesn't make sense. You can get an MK5 GTI golf. MK5 is the 5th generation of VK Golf. GTI is simply one of the models.
