The clasp pliers for hoses
A brand-new heat exchanger (available at dealerships for Volkswagen, Audi, Seat, or Skoda)
A kit for refrigerant funnels
New coolant (specific to your vehicle model)
First Step: Safety-First
Before beginning any work, ensure that your vehicle is situated on level ground and that the engine is completely cool. Gloves and protective eyewear are required, as you will be handling coolant.

(2) Remove the coolant


Identify the coolant discharge plug or valve located on the radiator of your vehicle. Carefully open the drain while positioning the drain pan underneath in order to extract the coolant. Be sure to dispose of the used coolant in accordance with the correct procedures.

Access the heat exchanger in Step 3.


There may be instances where accessing the heat exchanger requires the removal of interior ornamentation or panels. Consult the service manual for your vehicle model for specific instructions.

Step 4: Hose Disconnection

Identify the hoses connected to the heat exchanger and release and remove them using the hose clamp pliers. Anticipate the possibility of residual refrigerant escaping.

Remove the old heat exchanger in Step 5.


Remove the old heat exchanger’s mounting brackets by unbolting them. Remove it with caution from the vehicle.

Install the new heat exchanger in Step 6.


Install the newly installed heat exchanger and fasten it using the provided mounting fasteners. Reattach the hoses, ensuring that the hose connectors are used to secure them.

Step 7: Coolant Refill


Refill the coolant system with the proper coolant for your vehicle using the coolant funnel kit. Follow the manufacturer’s instructions regarding the correct coolant composition and quantity for your vehicle.

Eighth Step: Bleed the Air


Fuel the engine and allow it to operate while the heater is engaged. This will assist in the evacuation of any air pockets present in the system. Monitor the level of coolant and replenish it as necessary.

Step 9: Conduct a heat test


After the level of coolant has stabilised, inspect the cabin heater. Warm air should begin to enter the interior, signifying that the heat exchanger obstruction has been cleared.

So, looking back to the good old days,

. Then the modern driver knows nothing about car heating problems. As an old but active garage owner, I can go back in time to when certain cars were equipped with a blanket.

Yes, a blanket was provided to put over our laps, keeping us warm. Heaters were very finicky and fragile, often failing to work at all. Especially in cold winters. My first job as an apprentice mechanic brought me into contact with the first British Leyland minis.

These little cars were also freezing cold, with very ineffective heater systems that often failed the driver. Thankfully, things have changed a style including the addition of air conditioning to most car models these days.
