I've got a 98 4Runner, 105,000 miles, 4 cyl., 5 speed. My coolant is disappearing! I have to fill my reservoir every couple of weeks. There is no evidence of a leak. My oil looks good. Temperature gauge reads normal. Any ideas?

Thanks in advance,

I had a 4-banger 89 Camry with a small cylinder head gasket leak. So small in fact that the coolant evaporated when it hit the hot engine. No leaks on the ground, or on the motor, etc. I could, however, smell it from time to time.

One bottle of StopLeak cured it for about 25,000 miles.

Just an idea
