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.

Coolant leaking regularly but no evidence. Heating system has deteriorated...difficult to decondense. any ideas?


The MK4 VW's has a nasty habit of coolant (Glycol) buildup where it's leaking. It won't show on the floor but very noticeable where ever it's leaks if you know what to look for. As mentioned, checking your head gasket would have a high percentage causing your problem.

If it were a head gasket problem, steam would come out of your exhaust vaporized from the hot metal parts. If you don't have that, you can either check your oil for brown gooey consistency or the same goo in your coolant reservoir.

VW uses an after run auxiliary pump to keep the coolant circulating inside the hot engine block after shut down. This prevents the breakdown of the coolant from cooking itself from the hot engine block. With the use of an after run pump, circulation of coolant in the system after shut down happens and can last as long as 10 mins. Liquid coolant in a hot state leaking out will solidify as soon as air cools it down.

Coolant leak in VW Golf mark 5 1.9 TDi auto DSG


There is, however, an air outlet into the driver's foot area. If the heater core is leaking, the air coming through the heater core will carry the droplets into the entire air ducting system. The driver's foot area may be the closest outlet. If it smells like coolant, you need to replace the heater core regardless of where in the cabin the coolant is coming out.

There is a small vacuum pipe from the EGR solenoid that was disconnected, by reconnecting this pipe the problems (that I have had ever since I had a new head some 30,000 miles ago from a VW main dealer) have gone away.

Little plume of white smoke coming from engine when idling only. Runs great and not overheating. Really bad smell coming through vents with AC on


A little white smoke is OK from 0-15 minutes of start up.

After warm up the condensation inside the exhaust pipe AND under the hood should be purged.

How many mile is on the engine?

A well care for engine should not have to worry about leaky (pin hole leak) head gasket until 120,000 miles.

The other sources of coolant leak is the freeze plugs.

DO NOT WAIT! Take 15-20 minutes out of your schedule and see where is it leaking on the idle.

it can be at


heater hoses
water pump
freeze plugs
and head gasket


I would start monitoring the coolant consumption by making the coolant reservoir tank.

Keep tab on oil level.

====

The common A/C air vent odor are

coolant leak (even pin hole leak) on the heater core.

KEEP CHECKING the center to passenger floor carpet for wetness and smell of coolant.

and/or

mold in side the air tube vent.
there is cleaner spray you can buy to keep the mold.

1986 VW Golf heater blows cold air


The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.
if the car is not overheating, the thermostat is working fine.... replace or flush the heater core multiple times to try and eliminate sediment build-up.
