Mechanical Water Temp Gauge

[motormayhem]

Does anyone have issues with their temp gauges in the heat? I cant believe that it isn't effected by the 200* air in the engine bay and running 6" from the exhaust manifolds. Just trying to decide if I want to pay up for an electric one vs a mechanical one.

The only issue I have with my cheap mechanical temp gauge is that it sticks at the bottom sometimes if i haven't driven the truck for a few days. So it wont read anything for a while. And I've tried to tap the gauge but that doesn't help. But I would rather have an electric gauge.
