Coolant Leak Checks and Misc Tasks

TLDR

• Checked for Coolant Leak
• Redid fuel calibration on the left side
• Made a tool to install inspection hatches

Coolant leak

First thing this morning, I checked the level of coolant both on the overflow tank and the expansion tank. Both levels held through the weekend.

Next check: run the engine warm and let it cool down, then check if the level changes significantly.

Fuel Calibration

I wasn’t happy about the fuel calibration that I did a few weeks ago, especially on the left tank. During last calibration, I read the resistor’s voltages for every 2 gallons of added fuel. But I wasn’t happy about the readings as some of them were way too close.

Since I had to drain the fuel for W&B anyway, I took this opportunity to redo the fuel calibration on the left tank.

Same process as last time: 2-3 gals added to the tank in increments, and read/record the voltage readings on G3X. With experience from last time, the calibration this time went smoothly.

Inspection Hatch Install Tool

I removed all inspection hatches and re-installed them to check for smoothness. When installing the last one, my fingers were really worn out. I needed to build a tool to help me open/close inspection hatches.

I just a piece of scrap metal to make a U shaped handle, and drilled 2x4mm holes matching the distance of holes on the inspection doors. Then I pulled two rivets through the holes, but I ensured the rivets where only partially pulled, ie, the stem were not broken off from the rivets.

Then I tested turning the inspection hatches by inserting the rivet stems into the tiny holes on the inspection hatches. They turned much more easily. This tool is going into my baggage compartment’s tool box permanently.
