hi to answer ur questions if i drive say 30 min it still stays at the 1 notch mark now if i try to take cap off there is pressure the top heater hose doesnt get tight that u cant squeeze it like my other vehicles i have had in the past. it seems hot and the heater blows hot air that i can tell but then again its only like 14 degrees out
now what i did find is if i drove for a bit like shopping stays at the first notch now i got the the store spend 15 min there or less then i come back i turn key on and the temperature reading goes right to almost H then i start up van and then it slowly goes back down to the first notch once the engine is running its been doing that now so what does that mean
