Installation Instructions for a Calix Motor Heater



This post is by Rudi and Bertil, whom I would like to thank sincerely! Installation was carried out on a VW with a 1Z engine. For newer models, there are also installation kits available (see below).
A Calix motor heater is an electric motor pre-heater, used to provide more comfort during the cold season.
By pre-heating the engine using an outlet, the wear-and-tear associated with cold engine starts is eliminated, and the vehicle's heating system provides immediate warm air.

Helpful Special Tool:

Stable metal rod "A" 8-10mm diameter, approx. 70cm long, very pointed
• Stable metal rod "B" 8-10mm diameter, approx. 70cm long, rounded or flattened at the front
Quick-release screw approx. 6mm diameter, not too short, Torx
• Smaller, angled Torx screwdriver to fit the quick-release screw
Lockable 10 liter container for cooling water
• Stable cord (approx. 1m)
Possibly
• Silicone sealant

Preparation:
Run the engine while the coolant is warm (both radiator hoses should be warm), so that the thermostat valve is open (otherwise, you will need to drain the coolant).
(remove the power steering pump).

Execution:
Lift the vehicle onto a pit or a lift.
Remove engine noise protection.
verschandeln the lower cooling water hose and its surroundings with a damp cloth.
Squeeze the lower coolant hose with pliers and
Push it all the way from the top towards the cooler.
Attention, hot water may be coming!
Place in a container.
Pull the hose from the fitting and drain the coolant (approximately 6.5 liters). In case of
less (2-3 l) comes -> quiet swearing! (see below: Expansion of the servo pump)
Close the container and place it aside.
Re-insert the coolant hose onto the fitting.

Using metal rod "A", create a small hole in the center of the frost stop.

Screw into hole. Since it's somewhere between the exhaust and

Stop the rotation so that you can grasp the edge with pliers.

Expansion of the Servo Pump:

Remove the cover and loosen the two screws of the thermostat housing cover.
Remove the lid and brace yourself for a torrent of water. If there is no
Water surge hits rubber seal (lying loose behind the valve)
Carefully release (now water will come out!) and secure the valve.

Since the fitting usually doesn't clamp tightly enough during assembly,
if the valve does not fall out, the following can be done:

Remove the clamp from the valve body flange
• Remove the plastic sleeves
Insert the valve and seal
• Push the finger through the flange opening and use it to hold the valve in place
Now tighten the housing cover

The assembly is carried out in reverse order, essentially.

Recommended run times for the engine preheater:

- 20°C - 3 Std.
• - 10°C - 2 Std.
- 5°C - 1.5 Std.
• - 0°C - 1 Std.
- 10°C - 1 Std.

The "old" diving immersion heater unfortunately does not fit in the AXR or ATD motor. Also, in various cases
Other turbos with VTG (Variable Turbine Geometry) do not fit the immersion heater on the back of the engine block.
Companies like CALIX or also DEFA (which is distributed in Germany by WAECO) offer solutions for this.

On the pictures, you can clearly see the heater, which is inserted into the water hose at the oil filter flange.
