Checking water in motor and generator

I just use a piece of cardboard and dip it in the tank. I could buy new tanks but, meh.

An good ideae to check ph-nitrites -freeze level with litmus test strips especally if a Diesel.Also turn on cap TIGHT as system is under pressure.An if system has some age try to reach behind plastic container if it is a Freightliner of 1999 vintage an check best you can for cracked small hoses at connection .

ONLY REMOVE THESE CAPS WHEN THE SYSTEMS ARE COLD! Otherwise you could have a big surprise....

On my car with not very accessible and a semi-opaque reservoir, I find it works pretty well to slide a little flashlight up and down the reservoir and note when the glowing of the tank changes from off-white to greenish (or whatever color the antifreeze is). It's not necessary to make out the precise location of the fluid level visually to get a pretty good idea of where the transition is. This obviously works a little better in subdued ambient lighting, and presumably better with a flashlight with a narrow beam/small head (a penlight might work really well).

"becker".....On my Monaco, I made a dip stick out of a 3/8" wooden dowel that I stored in the engine compartment. I measured the exterior of the tank, since the Low and High were marked on the outside and marked the stick. When I needed to check I removed the reservoir cap and used the dipstick.

On the generator, you should be able to see the fluid when you remove the cap.

I remove the radiator cap from each tank overflow container and then look.

Your manual should describe how full each should be.
