If u have issues with heatting may be this will help.
1- If the carpet under
the heater core is damp, or if antifreeze vapor or steam is coming
through the vents, the heater core is leaking.Remove it and install a new unit (most radiator shops will not repair a leaking heater core.
1 - If the air coming out of the heater vents isn't hot, the problem could stem from any of the following causes:
- The thermostat is stuck open, previnting the engine
coolant from warming enough to carry heat to the heater core. Replace
- There is a blockage in the system, Preventing the
flow of coolant through heater core. Feel both heater hoses the
firewall. They should be hot.if one of them is cold, there is an
obstruction in one of the hoses or in the heater core,or the heater
control valve is shut. Detach the hoses and back flush the heater core
with a water hose. If the heater core is clear but circulation is
impeded, remove the two hoses and flush them out with a water hose.
- If flushing fails to remove the blockage from the heater core, the coremust replaced.
