Coolant Leak Issue, Need Help

If it only leaks while it is parked/cold, the most common thing is the water pump. Its the most often mis-diagnosed problem with chevy small-blocks.
Hundreds of lower rad hoses i sold. I would always offer the water pump,but customer is always right.

If its a leak other than water pump,a 15 radiator pressure tester will help.
Or a 45 dollar kit like this one. image.jpgOk,$46.95 in canadian pesos...
