    What do you mean by saying the coolant guage is all over the place. If you mean it shows hot then normal to back hot again, it is likely you have air in the coolant system and when the air lock gets to the pump then the pump can't move it.

If you refilled coolant in rad and didn't leave cap off & run it for a while with heat (not defrost) on inside vehicle, you probably have an airlock.
Let it run until rad fan comes on, & off, 2 or 3 times, and top up rad as needed 1"or 2" from top while it's running. Keep an eye on temperature gauge, that it doesn't overheat, and if it does start climbing too high, shut it off & let it cool down, and retry. If you need to do thermostat, we need to know exactly what engine you have. If you need to get it going fast, just bleed it as described and you may be alright for now. Where is this leak & how bad is it?

2004 subaru outback, heating system acting up


Thermostat Stuck on warm up & or you have
a possible head gasket failure & I would suspect
a loss of coolant.

If that is the case, you have a ruined exhaust converter &
O2 sensors as well & a $5,000 plus repair bill coming

Heater not working,engine smells hot,temp gauge stays in blue zone


A. Do you have a Coolant Leak causing the smell? What is the Radiator Coolant Fluid Level? Have you been adding alot of Fluid?
OR
B. Replace the Thermostat. The Thermostat is stuck closed.

Either one A. or B. causing the:
1. Engine to overheat, because there is not enough fluid or the thermostat is stuck closed not allowing fluid to circulate.
2. Heat is not working because the heated (hot coolant) is not travelling to the heater core.

Would the heater control valve malfunctioning make the engine overheat blowing hot air out the heater one moment,then not blowing the hot air, temp gage spikes 225 plus. The motor takes awhile to heat up...


Heater control valve malfunction will not cause engine to overheat unless coolant is leaking externally...Overheating going down the road can be the result of a few different things...Partly clogged radiator...Insufficient air flow due to possible fan problem...External coolant leak...Make sure fans are operting properly and have cooling system pressure tested for leaks...Gaining and losing heat on the inside of the vehicle usually means system is low on coolant but you must find out where coolant is going

Overheating, low fuel efficiency, fuel smell in cabin


Sounds like coolant ports in the engine block is gunked up. Did you maybe notice the coolant ports when you changed the head gaskets? And, or, change the radiator cap,if you haven't already done so, I've seen them heat up over that too.

OVERHEATING


This could be a multitude of things:

Stuck closed thermostat.

Cooling fan not coming on.

Clogged radiator.

Low on coolant.

Water pump failing/leaking.

Head gasket blown, leaking exhaust into antifreeze.

Clogged catalytic converter.

Thermostat: If the Van heats up, then feel the upper radiator hose. If it's cold, then your thermostat is closed. Replace thermostat.

Coolant: If low, simply fill with distilled water and coolant. Low levels will let engine over heat.

Radiator: If there are cold-to-the-touch spots on the radiator after it should be warmed up, then a clogged is probably occuring. Have radiator flushed.

Head Gasket: If you smell exhaust fumes in your coolant reservois tank, then you got a blown head gasket.

Cat Converter: Only can be tested if off the car. Or you could try a non-contact thermometer. These are also good to testing cold spot on radiator or if thermostats are open.

Cooling fan: If mechanical it'll be spinning. If electrical, it should come on automatically with the A/C, or when it gets hot.

Water pump: Will be leaking from the front if it needs replaced. On a van, it's a tough job.

Good luck!

02 Alero not overheating, no heat


When you say not leaking antifreeze has your coolant level gone down at all? and is it that you have seen no leaks where you park it? What worries me is you can smell it when warming up, have you felt the interior floors to see if damp and do you get any condensation if put blower onto screen, if so then heater matrix is leaking if not could be down to headgasket and/or cylinder head leak.

Ford Escort -1998 low temperature gage


Replace the thermostat, if that does not cure the issue you have a slight head gasket leak. I am a retired Ford dealer tech and this is what I have found causes this issue.
