What is the purpose of the Temperature Gauge Calibration Kit?

This kit is designed to correct errant temperature gauge readings in your Vanagon, often occurring after installing new temperature senders or aluminum thermostat housings. Its goal is to ensure your gauge reads accurately by using the radiator fan thermo-switch as a calibration basis, rather than simply forcing the gauge to read lower.

Do I need to buy this if I'm already getting the GoWesty Aluminum Thermostat Housing Kit?

No, you do not need to order this separately if you are purchasing the GoWesty Aluminum Thermostat Housing Kit, as the calibration kit is already included in that bundle.

What parts do I need to have installed for this kit to work correctly?

To ensure accurate calibration, it is important that your Vanagon has the correct part numbers for both the thermo-switch (251-959-481K) and the thermostat (025-121-113F).

Can I use this kit to fix a Vanagon that is actually running too hot?

No. It is very important that your entire cooling system is in proper working order before using this kit. You should make any necessary repairs first if you are in doubt, as this kit is for gauge accuracy and not for fixing an engine that is physically overheating.
