Carlito asked:


I was wondering that if I put a heater in a 10 Gallon tank that has dividers, will the heater heat the whole tank or just the place where the heater is? And also, where can I get a heater for a 10 gallon tank?

I have a 1999 blazer and it is not heating properly. Today i went out driving and came back home and the hoses going to the heater were not even hot. So i assume the heater core is plugged up or not working. Is there any way to unplug it without taking it out? And also how hard will it be to take out and replace if i have to? I am assuming it is behind the dash because the hoses go through the firewall.
