WD69 - Checking Coolant Regulator and Replacing it if Necessary (Workshop Campaign)
Vehicle Type:
911 GT3 (991)
Model Year:
2014
Concerns:
Coolant regulator
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a
possibility that coolant regulators that do not meet the required specifications may have been
installed on the affected vehicles over a limited period of time.
As a result, the coolant temperature might increase to above the permitted temperature range after the
engine has been running under load for just a short time.
Action
Required:
Check the function of the coolant regulator and replace it if necessary before vehicle delivery to the
customer.
Affected
Vehicles:
The VIN(s) can be checked by using PIWIS Vehicle Information link to verify if the campaign affects the
vehicle. This campaign is scope specific to the VIN! Failure to verify in PIWIS may result in an improper
repair. This campaign currently affects 173 vehicles in North America.
Parts Info:
NOTE: Parts must be ordered via a PTEC/PAV after inspection and determination that
replacement of the coolant regulator is actually required.
Tools:
•
There are no parts required for checking the coolant regulator (Scope 1).
•
Parts required for replacing the coolant regulator (Scope 2):

Attachment "A": Work Procedure
Checking function of coolant regulator
Work
Procedure:
Information
The function of the coolant regulator is checked by determining whether the coolant pipes in the front and
rear end area heat up after a certain coolant temperature is reached.
•
The section to be checked at the front of the vehicle is behind the air vane, directly in front of the
radiator inlet (supply) at the front left in direction of travel.
Body front section, left

The section to be checked at the rear of the vehicle is after the radiator outlet (return) at the
left-hand side of the engine compartment at the same height as the longitudinal member.

Technical Information
Before starting the engine, position an exhaust extraction system behind the vehicle’s exhaust pipes and
switch it on.
4
Start the engine and leave it running at idle speed
until a coolant temperature of 140° F (60° C) is
reached.
The coolant temperature can be read from the
coolant temperature gauge in the instrument cluster
 Coolant temperature 140° F (60° C).
Coolant temperature 140° F (60° C)
CAUTION
Hot components
•
Risk of burns

Wear personal protective gear.
Information
If the coolant regulator is working properly, it will still be closed at a coolant temperature of approx. 140°
F (60° C). The coolant pipes at the front and rear of the vehicle have not yet heated up above the ambient
temperature at this time.

Once a coolant temperature of 194° F (90° C) is
reached, the large cooling system will be opened.
Information
As an alternative to checking the temperature by touching
the coolant pipes, a temperature probe can also be used.
When using a temperature probe, the ambient
temperature directly at the cold coolant pipes is measured
during the first measurement and shown in the display.
After opening the large cooling system, a significant
Coolant temperature > 194° F (90° C)
increase in temperature of approx. 68° F (20° C) at the
front coolant pipe is shown in the display. Subsequent activation of the radiator fan indicates that the
coolant regulator is working properly.
6
Check whether the coolant pipes at the front and rear of the vehicle heat up above the ambient
temperature.
If the coolant pipes at the front and rear do not heat up because the coolant regulator is closed
and the coolant temperature increases to 221° F (105° C), stop the engine immediately.
Information
The coolant regulator must be replaced in the following situations:
•
Coolant temperature increases to 221° F (105° C).
•
Coolant pipes at the front/rear left do not heat up above the ambient temperature.
•
Coolant regulator remains closed.
•
Coolant leaks out of the reservoir.
•
The message "Engine temperature too high" is displayed in the instrument cluster.
The coolant regulator must not be replaced in the following situations:
•
Immediately after reaching a coolant temperature of 194° F (90° C), the coolant regulator opens and
the coolant temperature drops to below 194° F (90° C).
•
The large cooling system is active and the coolant pipes at the front/rear left heat up.
7
Stop the engine.
8
If the results of the previous check indicate that the coolant regulator must be replaced, replace
the coolant regulator as described in the Workshop Manual  Workshop Manual '195819
Removing and installing coolant regulator'.
