Hey everyone! Trying to get some ideas of where to start. On Sunday I began to start smelling antifreeze through the air vents, passenger side floor board is dry/not showing signs of a leaking heater core . Windows aren't fogging up either when the heat is running, and I'm smelling a burning coolant type of smell coming from the passenger side of the truck near the front. I can't pinpoint where its coming from, nor can I see any visible leaks.
To top of it off, the engine won't go past 160 deg and seems to hold there. Any ideas? The water pump, hoses and thermostat were replaced a few months ago. I had a defective Delco thermostat and threw a motor rad one in place at the time the pump was changed out. I should mention the top radiator hose is warm, but not hot either. Any ideas? I was thinking maybe the thermostat is stuck open, the motor rad one supposedly stays in the open position (supposedly at the 180 deg mark).
UPDATE: So I was outside trying to see if I could spot a leak, and this broke when I went to move it...well there goes all the coolant to boot. Looks like it leads from the thermostat housing to the firewall.
