Most likely the thermostat. The heater bypasses the thermostat. If the thermostat is blocked the only cooling is via the heater matrix. To check start the engine with the heater off and put your hand on the thermostat housing when the thermostat opens you should feel the housing get hot. If it doesn't the thermostat is faulty.

The mechanic should check the engine for the problem that is happening . when an engine overheats , it means that there is a problem in the cooling system.When an engine over heats rapidly there is no function of cooling system in the engine.As usual you have to flash the radiator water and refill it again ,then check the thermostat if worn out or destroyed. if worn out or destroyed replace it.The cooling fins in the radiator must be check also, the heater if it is working it means that there is no problem in the heater .But the heater should be check if its function is good because of the reason that it is affecting the cooling system. the engine should be check most specially the engine oil. Because of some times the cause of the rapid heat in the engine is that if the engine oil is dirty then it will cause the engine to over heat that easy and cause fast engine over heat.There fore you should change the oil of your engine "change engine oil".To prevent engine over heat.

What is the problem with: Frozen weather: 97 Ford Escort overflow boiling, there is coolant/antifreeze in radiator and the car started idling VERY fast when at a stop.


Ouch, Worst case sounds like if bubbling you have a head gasket problem. OR a belt broken, so the water pump is not working, or antifreeze mixture is not correct and is like "slush" instead of fluid and cannot cool properly, boiling somewhere in the engine. Idle change sounds like the broken belt or belts problem. Hopefully that all it is. Check and fix soon.

Check the serpentine belt routing. The water pump may be running backwards. There should be a sticker under the hood with the belt routing diagram

2003 impala heater quits working sometimes and it overheats sometimes


You should have it checked out right away, before the overheating does any damage to the engine. The whole coolant system should be inspected to find the cause. It may be a simple fix, maybe not. Are you adding coolant constantly? Do your radiator fans come on when it starts to overheat?
When it gets too hot, it may be boiling coolant away, and the low coolant level will cause the heater to stop putting out heat.

94 escort LX wagon 1.9L... (180,000k miles). Fan works with diagnose jump (STI to EEC), doesn't work under normal running (near overheat,etc..). Cat Conv going bad ("check engine" light 'smells funny'),...


As your diagnostic flow chart will tell you now you need to test the coolant sensor(3 wires sensor in water jacket screwed into steal pipe near intake manifold) Most likely out of range.If the first part of your pinpoint test had failed then there might be a possibility of and open inside the pcm but since it passed the first test then I don't think they are a related concern.

OVERHEATING


Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
If persistent boil ups/over attention must made in the cylinder head
or gasket area, or possibly water pump?

Engine overheats when heater pipes connected


I think you could be right about there being air trapped in the system.
Or the heater core(radiator) is plugged.
Either way you need a pressurized radiator coolant pump to put the coolant in without air being trapped.
Although,i have seen it done by jacking the vehicle up high enough that the radiator was now higher than the heater core level, and then the coolant was put in.
But this is dangerous to try.

Your coolant system aint heating up like it should. Its your thermostat. You need to change it. its broke. There are four parts to your thermostat. You need to make sure that you get all four parts out. A thermostat costs about five bucks. Its an engine temp. regulator. If its broke your engine wont warm up at all. If it seizes shut, your engine will overheat. Your thermostat is broke. I Have the exact same car that I have been repairing for the last three months.

Replace the thermostat in the engine coolant system - should be near the water pump or in the top hose to the rad. Mist in the heater vents usually means a corroded heater core, that should be replaced. Be sure to use the correct mix of anti-freeze, to keep the boiling point in the cooling system correct. Many who live in the warmer states, thing that plain water is OK, but it is NOT. Antifreeze contains corrosion inhibitors that protect the engine cooling system.
