87 pickup losing coolant
I have an 87 4X4 with 163k on it. I bought it 3 years ago, and replaced the radiator. I have recently flushed the cooling system, replaced the t stat, and coolant. In the last few days I noticed the heater not working as well as before. The PO had alot of stop leak in the system due to the bad radiator I replaced when I bought the truck.
I'm wondering if the stop leak was stopping a head gasket leak as well? I'm losing about a pint of coolant a day give or take how much I drive. The truck doesn't run hot, and the gauge never gets half way between c and h. IS the head gasket going or is the heater core clogged or leaking? I looked under the pass floor mat and it's wet, but I don't think it's coolant.
Any ideas on this would be greatly appreciated..

That's a big negative, no coolant on the ground ever. I'm suspecting the head gasket is starting to go. I'll check the heater lines tomorrow, but I never smell coolant in the cab. The WP is behind the radiator on my rig I'll look for any leaks as well. It's just weird though the truck doesn't get hot,,,, Yet

The low heat could be a clog in the heater core (gets hot but then flow is restricted, cooling it down) or your t-stat might be rated for too high of temperature. Did you use a 180 or 195 degree t-stat?
Also, you won't notice coolant on the ground unless you water pump has already failed (which it hasn't). Mine is going currently, you'll just notice coolant residue seeping out from the bottom of the timing cover on the front of the engine block. Look from below and you'll notice it if it is leaking.
