How do I fit my capillary type temperature gauge? |
|
This type of instrument is mechanical (part number is prefixed TG of TL) and therefore does not return to zero when the ignition is switched off. The gauge and the temperature sensing bulb are permanently connected by a flexible metal capillary tube. The whole system is liquid -filled. DO NOT try to separate the gauge or bulb from the capillary The bulb should be fitted into such a position that it is fully immersed in coolant or oil. The tubing should then be securely cleated to some part of the engine, approximately 3" - 4" from the bulb. Bends must not be less than 1" radius. The tubing should then be run down the engine toward the bulkhead, and be securely cleated every 4" - 6". From the last cleated point on the engine to where the tubing passes through the bulkhead, there should be arranged 3 or 4 coils of not less than 2" diameter. From the bulkhead to the gauge, it is not necessary to insert any more coils unless there is an excess of tubing.
