My blazer will sometimes have heat but lately there is no heat, I noticed a small leak around the water pump could that be the problem with my heat or could it be something else?
I open the radiator cap and when the thermostat opens the fluid levels drops as it opens, the reservoir still keeps some in it as well. Need some advice on what to look for so I know what kind of expense I'm in for.
Thank you..

have the coolant system pressure checked for leaks, make sure you have coolant in tanks aswell, it may be lowso itstops heating.
