where is the heater block on a 2004 saturn vue?
The heater cor was replaced but it is still not getting warm
I have a 1992 Olds with the 3800 engine; the block heater is almost inaccessible. The engine is sideways and the block heater is in the frost plug location just over the frame at the back. Suggestion: unless it is leaking just take the frost plug out in the front of the engine and install the block heater there where it is accessible. Duane
The engine coolant level is low or needs to be flushed, and replaced.
replace your heater hoses going into and out of the heater core. One of them is probably split.
Inside engine compartment passenger side at firewall
If it has a block heater it will be installed on the passenger side of the engine , in place of one of the freeze plugs ( core plug , expansion plug etc )
Possible air lock in the heating pipes. Common after changing thermostat. look for a bleed screw on the heating pipes between the engine and interior, or loosen one of the heater pipes., after engine has warmed up. Run engine to dislodge trapped air.
The obvious answer would be that its not getting fuel. Have the fuel filters been changed?
There are hoses in the engine compartment that go to the heater core. You can remove the intake and out going hoses from the heater core. You have to either block off these hoses or connect them together, depending on the make of the vehicle.
It connects to a heater hose behind the engine.
How do you bleed the heater after changing coolant in a 1992 4runner
