Looks like I've got 2 small coolant leaks that I need help with fixing.
I've got a small leak dripping out of the bottom of my heater bypass valve. Shouldn't be a big deal to replace. When I replace it will I need to replace the 4 clamps on the hoses that attach to it at the same time?
The second I need help finding. It's a small leak and it's intermittent. I saw coolant dripping off the bottom radiator hose and assumed the hose was worn out and replaced it. Turns out it didn't fix the leak and after further investigation I saw coolant running down too the hose from above it. At this point I'm thinking it's coming form the bottom of the water pump but I want to know for sure before I go and replace it. It's hard to see up in there. The hose was only 15 bucks and I needed to flush the radiator anyway so that's not big deal, but I don't want to spend the time and money to replace the water pump just to find out it's something else again. What else could it be?
I think I remember the previous owner telling me that he had replaced the water pump at some point already and I wouldn't think that it would go bad so fast since it's only at 102k miles.
The engine did get a bit hot last week which was when I realized I had a leak. I discovered the coolant was low by at least a gallon and I was also low on oil. Shame on me.
The engine got to about 230-240 for probably less than 15 minutes before I realized it was running hot. Maybe a water pump gasket failed because of this?
What do you guys think?
What else could be leaking besides the water pump?
Is this coolant coming from the weep holes on the pump telling me the pumps' barrings are going?
When I replace my heater bypass value do I need to replace all 4 hose clamps too?
