For those 2Fifty owners who need to fit new senders for water temp, I did mine today. It was very easy. Locating the spare plug was the first task. It's quite obvious when you get underneath and look under the exhaust manifold from the front.
I found that I was able to unscrew the plug, and keep my finger in the hole until I screwed in the sensor. I only lost a 1/4 cup of coolant
.
Just be aware the plug and the new sensor are different sizes so make sure you have both size spanners with you before you unscrew it.
Then I found a way of making sure the cable does not go anywhere near the hot exhaust, so I routed it through some old rigid plastic tubing I had lying around.
All good.
Then I tested a few of my electrical connections, including the fuel gauge. I remember when I removed the old fuel gauge back in October it was reading just under 1/4 full. The new gauge is reading 1/2 full, so either I've gained some fuel, or something's not quite right.
I have fitted the resistor.......
