Hey all,
I'm losing some coolant somewhere on my 1999 Mazda B2500 at the rate of about 1/4" in the reservoir per week. I'm not sure where, it's not leaving any sort of drops or puddle underneath. I also crawled underneath the truck and it's completely dry, no trace of an external leak. I've been checking the oil religiously for any sign of a bad head gasket, no snot-like consistency or graying of the oil.
I'm going to replace the radiator cap tomorrow, maybe it's not getting a sufficient seal and is letting some steam/vapor out? Not too sure, but for $8 it's worth replacing. Maybe a pinhole leak in a hose? I'm going to replace the hoses here soon. I was thinking maybe water pump or something, but again, it's completely dry underneath. Also, I don't suspect the heater core, as the carpet inside is totally dry, no sign of a leak.
I'm just trying to figure out where this coolant is going. I hate not knowing where it's ending up.
Thanks in advance.
