I developed a leak on my backhoe yesterday. oil coming from under the radiator. i took the front guard off, cleaned years of dirt/grime out. started it up and i have a small line that goes up to the small cooler that looks to have a pinhole in it. the line where its leaking is in the bottom. i think if i remember they make some sort of a clamp device you can put around those line but i don't remember what they're called. if anyone else knows the name of it i would appreciate it and also if you have another way to fix it without removing the whole line which with my disabilities i may not be able to do. old vet needing some help. thanks for reading.
