I have a 2003 H2 and noticed coolant on the driver side floor, where is that coming from, I don't appear to have a leak up front but obviously I do.

 

most likly a heater core issue ,,are you getting any slim on the front windows ?if yes its a heater core problem .,,,mike

 

nothing is wet anywhere, no slime on the windows or windshield, nothing dripping underneath, nothing seems wet under the hood. It may sound stupid, but we noticed this when the heated seats where used, may have nothing to do with it, but its for sure anti freeze on the floor of the drivers side. nothing above that leaked down.

 

Spoke to soon I think you are 100% right, thanks

 

Not sure how common it is but it may be the water pump weep hole, which came unsealed or needs a gasket replaced etc.

It can be kinda confusing to find out if it is it since it probably leaks at random

 

Has anyone ever heard of getting your oil filter changed and sometimes they bump the heat coil and that can cause it to start leaking.

 

There is no way that an oil change will cause a heater core to leak. I think it's just a coincidence.

 

heater core and the a/c evaporator ,both are just small radiators
are located under the dash ,if the fluid is green its antifreeze.and the core will have to be replaced .some times the drain line on the evaporator will glog and you will get clear water on the pass side floor .from running the a/c , then you would clean the drain line out hope this helps mike
