which engine does yours have?
on machines, all, fix noise first. noise means , i'm going to blow up
or die, or fly apart, or cause you damage or the engine collateral damage, (damage can be unlimited)

my wildest guess, I'm blind see and deaf, is the water pump is getting ready to blow up. Self destruction as all do, if ran to infinity.

the fan must turn on at all overheats or it is bad, or its trip sensor is bad or its own relay is bad or the wires, end to end this path are bad.
some cars have 3 fans, 2 on rad rear and 1 on AC,
my comment is RAD FAN(s).

asking for help to blind people on the net./ why not get hands on help, you in YUKON? ask a neighbor, to look or friend or son or some with machine experience,
doing it wrong can be very expensive. why risk that.?
or get hurt.
see here for vast overheating reasons, and works for all cars.
(no electric pumps)
http://www.fixkick.com/overheating.html


on newer cars the PCM controls all fans, under ALL conditions via RELAYs.
the varies by year, model , country and engine options.
what country is this car.?
cabrio
or
Cabriolet (missing let?)
cabribe? mexican?
a gen 3:!
Third generation (A3/Typ 1H, 1993-2001)
the Mk3 Golf Cabrio received a Mk4-style facelift for the late 1999 model and was continued until 2002.
here is the list, what engine?

SOURCE: overheating problem

looks like you have done everything but the problem with your car is that the cylider head gasket has gone have a look at the dipstick or remove the oil filler cap if it looks like mayo then 100% head gasket has failed you said no water on the floor so it must have gone into engine only way this can happen is head gasket failing, if you have put lot of water in to the cooling system then your sump will be full of oil water mix.

let us know your findings so we can help you more if you need it

SOURCE: VW Golf 2.0 is overheating after replacing thermostat.

there is a strong possibility that the impellers on the waterpump are broken!!!!. they are made out of plastic and are notorious for breaking. ck this first have seen it countless times. make sure new waterpump has metal impellers.

SOURCE: My VW Cabrio is overheating after 1-2 miles.


Run the engine and look at the header tank , is there lots of air bubbles coming back out of the water if is then the head gasket may have split and that is down to either a can of Radweld or a strip down repair

If the radiator is not uniformly hot them I would go for that as your problem

Normal operation is that the engine starts the thermostat is closed , engine block heats up and opens water starts to circulate around the block

So to check that you need to fill the radiator with cold water run it for a few minutes check the bottom hose it should be cold

The stat opens and the bottom hose should get hot as the water from the block is pumped into the radiator for cooling.

The radiator should get hot all over and the cooling fan should kick in when the sensor hits the over limit stop.

If that does not happen then get someone to remove the stat altogether (It is only there to get the engine block warm quickly in cold regions )

In which case the bottom hose should go from cold to warm to hot

SOURCE: Loud engine knocking on 2001 Ford Focus

Sounds to me like a very common problem has occured to your neighbor. If this is a SOHC engine, one of the valve seats in the number 4 cylinder has fallen out. I'm sure it has damaged the head and the piston. Stop trying to run it or you might blow a hole in the cylinder wall or break a rod or both.

hi, have you changed the coolant thermostat. you can check this by taking out the thermostat boil it in an old pot and if it OPENS it is o.k.. or bleed the system of coolant take the highest coolant pipe off WHEN COLD and lower it down if flowing then the coolant pump is working. the radiator could be blocked. the engine coolant pump fins can corode (this can warm the coolant too), need to check if coolant is ciculating. the coolant dies after 3 years. gerry

Cadillac dhs 2001 over heating


The most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.The hose goes in to the engine to a crossover and comes out the other side to near the thermostat housing,the blockage may be there.

Vw golf 2001. coolant system not working


Your most probable cause for this is because your water valve needs replacement or repairing. Not all cars have a water valve that brings the heated coolant into the heater core unit.

Essentially, the heated coolant is brought from the engine block directly, into a mini radiator that has a fan to blow heated air into your vehicles cabin.

If that valve were clogged, or the switch itself to open up the water valve that blocks the coolant from going into the heater core unit, then you wont be able to get heat from the vents.

ALSO, another reason why your car might also be overheating as well, is you need to check your coolant levels as well to make sure it is fully filled up, if it is, then your thermostat might also need replacement.

good luck with your problem.

Overheating Polo


this sounds like a thermostat fault, but also could be the sensor switch to the radiator but is more likely the thermostat, it should be located at the front top of engine, follow the top water hose to the engine and you will find the thermostat housing, also just a heads up, these had a problem when first made, according to the known fixes and problems with VW's the hoses corroded inside and started loosing water, this could be wise to get the system presure checked to...hope this helps

Dont know where thermostat goes. engine overheating, coolsnt not cycling.


The thermostat is bolted into the bottom of the water pump, the lower radiator hose connects to a cover that holds the thermostat to the water pump.

the thermostat can be difficult to get at because the AC and power steering pump are all bolted on top of the water pump,

Your problem may not be a bad thermostat.
I would also check:

1) water pump, some of the vw pumps are poorly made & tend to go bad.

2) fans belts, it can be tricky to get the right tension on these belts due to a badly designed tensioner system on the power steering & water pump belt.

3) hoses, radiator, coolant tank,. the radiators and coolant tank tend to leak when they get old, the plastic cracks or the rubber seals go bad.
Also check the electrical system controlling the engine cooling fans. there are sensors and relays that can go bad.
I have owned 8 vw's most of the major problems with these cars was due to electical problems.

4) Engine problems such as a blown head gaskets, or ignition timing problems can cause overheating. luckily VW engines usually don't have these problems, unlike other companies 4 cylinder engines (the Dodge Neons for example)

It will probably be your thermostat that is jammed open , try fitting a new one , the thermostat is located in the housing on the side of the engine usually just above the gearbox , trace the top radiator hose to the engine and you should be able to find where the thermostat is ,
