That is NOT safe, way too hot. Your fans are broken probably.

Laptop cooling fan running at very high speed


Try loading and using a program called speedfan to control your fan speed if that is appropriate. This can also show you your CPU temperature (if you can figure it out). Core Temp can show you temperature of modern CPUs, amongst others.
Otherwise try cleaning you CPU of dust - search the internet as to how to this safely.

Water leaking out of overflow from heater core.


If coolant is leaking from the heater core into the interior or through a weep hole out of the car your heater core has sprung a leak.
Most vehicles have easily accessible heater cores, only requiring removal of a panel under the dash or hood to gain access. On the '97 Skylark it's accessible under the dash.
  • Disconnect the negative battery cable.
  • Drain and recycle the engine coolant.
  • Raise and safely support the front of the vehicle.
  • Detach the drain tube, then disconnect the heater hoses from the core tubes.
  • Carefully lower the vehicle.
  • Remove the console if equipped.
  • Unfasten and remove the sound insulators, console extensions and/or steering column filler, as required.
  • Remove the floor or console outlet ductwork and hoses.
  • Remove the heater core access cover.
  • Unfasten the heater core mounting clamps/bolts, then extract the heater core from the vehicle.


To install:
  • Install the heater core, then secure using the clamps/bolts.
  • Fasten the heater core cover.
  • Connect the outlet hoses and ducts.
  • Install the sound insulators, console extensions and/or steering column filler.
  • Raise and safely support the vehicle.
  • Install the drain tube and connect the heater hoses to the core tubes.
  • Carefully lower the vehicle.
  • Connect the negative battery cable.
  • Fill cooling system and check for leaks. Start the engine and allow to come to normal operating temperature. Recheck for leaks and check coolant level. Add if necessary.

I put a brand new heater core, radiator, water pump an thermastat but it still takes forever to blow heat out an then it doesn't get that hot.. what's the problem? my vehicle is a 1995 jeep wrangler 2.5 4...


Could be the heater bypass valve is stuck or the heater core is blocked.
I'd check the heater core first.You may have trapped air in the cooling system or the heater core may be partially plugged up. Engine coolant is delivered to the heater core through two heater hoses. With the engine idling at normal operating temperature, set the temperature control knob in the full hot position, the mode control switch knob in the floor heat position, and the blower motor switch knob in the highest speed position. Using a test thermometer, check the temperature of the air being discharged at the HVAC housing floor outlets.
Temperature Reference
Ambient Air Temperature 15.5° C (60° F) 21.1° C (70° F) 26.6° C (80° F) 32.2° C (90° F)
Minimum Air Temperature at Floor Outlet 52.2° C (126° F) 56.1° C (133° F) 59.4° C (139° F) 62.2° C (144° F)
If the floor outlet air temperature is too low, Both of the heater hoses should be hot to the touch. The coolant return heater hose should be slightly cooler than the coolant supply heater hose. If the return hose is much cooler than the supply hose, locate and repair the engine coolant flow obstruction in the cooling system.
OBSTRUCTED COOLANT FLOW
Possible locations or causes of obstructed coolant flow: Pinched or kinked heater hoses. Improper heater hose routing. Plugged heater hoses or supply and return ports at the cooling system connections. A plugged heater core. If proper coolant flow through the cooling system is verified, and heater outlet air temperature is still low, a mechanical problem may exist.
MECHANICAL PROBLEMS
Possible locations or causes of insufficient heat: An obstructed cowl air intake. Obstructed heater system outlets. A blend door not functioning properly.
TEMPERATURE CONTROL
If the heater outlet air temperature cannot be adjusted with the temperature control knob on the A/C Heater control panel, the following could require service: The A/C Heater control. The blend door actuator.
The blend door. Improper engine coolant temperature

Heater hose broken


Bypass - no, it would be like a short for the cooling system, a sure way to overheat the engine. But you can just close it completely by adding another valve on the hose and closing it.

Can not find heater control valve 2000 expedition


what year? for 2000, there are no control valves. It mixes a/c air with heater core air to blend the right temp.

SECTION 412-02: Heating and Ventilation 2000 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION Heating/Defrosting The heating and defrosting system has the following features:
  • Controls the temperature and, during A/C operation, reduces the relative humidity of the air inside the vehicle.
  • Delivers heated or cooled air to maintain the vehicle interior temperature and comfort level.
  • Controls the A/C blower motor speed.
  • Cooling or heating can be adjusted to maintain the desired temperature.
  • Uses a reheat method to provide conditioned air to the passenger compartment.
  • The blower motor draws outside air through the A/C recirculating air duct, except for MAX A/C cooling, when recirculated air is used.
  • All airflow from the blower motor passes through the A/C evaporator core.
  • The temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature.
  • The temperature blending is controlled by the temperature blend door, which regulates the amount of air that flows through and around the heater core, where it is then mixed and distributed.
