disappearing coolant
disappearing coolant I have a weird problem. My car never shows any sign of leaking coolant, but sometime when I open the radiator cap it's a little low. When I check the coolant dip stick it read completely dry even after I fill the radiator. Why?

your overflow tank is an "active" tank. Do not fill the radiator through the cap. Always fill the resevoir tank. When it gets hot it puts the excessive coolant into the overflow tank, when it cools, it sucks it back into the radiator. When cold, your radiator may "look" low, but will soon fill up once it gets hot. The other option is so pressurize the cooling system, and look for a leak, if no leak is present, you are burning it through the heads. our intakes are dry and do not have coolant running though it. most likely if you are burning it, you should not have to add coolant very often. if you are adding often, then you have a leak, check your waterpump and hoses.

I had a leak on mine about a year ago. Turned out to be the lines that run coolant through the TB. I did the TB coolant bypass and I didn't notice a small crack in the rubber tubing, which led to coolant dripping out little by little until it was eventually empty. Check all your lines that coolant runs through first for cracks, that should be your first step.
Get a new radiator cap and see if that fixes the issue. Usually will.
But if you do decide to do a radiator pressure check......make sure you remove all 8 spark plugs first. If it is your gasket thats leaking, you may fill a cylinder with coolant during the test, then when you start the engine you could hydralock it and then you might have to buy a new engine.
