I replaced my radiator and hoses around three years ago. It was O.K. since. Then last week I checked the coolant/antifreeze level from the radiator and the reservoir. I was surprised to see the coolant is a little low from the radiator, but not bad and the coolant in the reservoir is almost empty. I refilled coolant to the maximum level. I checked again this morning. The coolant/antifreeze is again a little low at the top of the radiator and almost empty in the reservoir. I looked around the radiator and hoses, but I didn't see any leak. I changed my water pump last year. Do you have any idea how to track the source of leak?
look around for white crust from the antifreeze, when the car is cold squeeze the radiator hoses you could have a crack. I had a crack on an old car no signs of a leak then i started squeezing the hoses and found the crack it was leaking from.
Thanks. I just found a pool of coolant on the top of the transmission. It must be leaking from the hoses over there. I will check tonight after I come back home.
A few years ago, same thing happened, but I didn't know where it was leaking because I couldn't actually see the leakage. Later I discovered that it was leaking from under the clamp of bypass hose. When I removed the clamp to change the hose, there was a crack at the end of the hose right where the clamp was. The coolant was dripping from there.
Thanks. I checked this evening to find out what's wrong. I removed air cleaner for better access. I found a couple of leaves stuck inside the air cleaner. That's a bonus. The suspected leaking area is near the thermostat housing. I squeezed the hoses, but I didn't see any leakage. I drained coolant and removed clamps. I found out that one of the clamp screws are a little loose. Also the inside lining is beginning to detach. These hoses and clamps are not OEM. They are only three years old. I think I need to replace with OEM parts.
