yz 400 coolant loss

2 posts in this topic

I'm new to this site and wanted to know if I could get some help. I have a 98 YZ 400 I enduro race. Earlier this summer I think I overheated it and now I cant keep water in the radiator. I've tried different radiator caps, replaced the seals on the water pump. Has anyone had this problem and what could be the cause? I'm scared I cracked a head or cylinder. The water is not going out through the overflow on the radiator or through the water pump seals. There is no water in the oil either. The bike will lose about half the radiator in about 8 miles. The bike still runs great though. Any ideas would be appreciated.

Thanks

Woody
