Well I'm getting in closer but just noticed some coolant on the fins of the radiator?
Just bought this P10 Stepvan last winter and I have been fixing it up.
I do have it running and driving around the parking lot but I never noticed this fluid sitting on the fins of the radiator?
Is this the original radiator? I am stunned if it is but I looked up Harrison radiators and they seemed to be the original equipment?
Do u all think that bars radiator stop leak would be good for this problem? Or am I looking at a radiator repair/replace?
