lower rad hose temp during winter
Ive been trying to determine my problem of my heater only blowing 100 degree air. Ive replaced the heater core and all the flaps are working correctly. The control valve is working too. One thing i noticed is after 30 minutes of driving in 20 degree temperatures the lower radiator hose was still about 50 degrees. Is this normal for this time of year? Because it kind of had me suspecting the water pump not circulating well after noticing that. The motor is running at 180F as tested by a heat gun at the thermostat housing and ive put 2 different ones in it.
A few days ago i spent half an hour bleeding the system with the front raised up and got it to blow a litter hotter but not as hot as it should be. There shouldnt be any air bubbles i would think.
