Or it's a fill tank like this.

Ok.. thanks! I have the fill tank. Guess I was expecting an actual cap right on the radiator as in a production car with the fill tank being just for overflow.
Is there a radiator drain valve? Do you use a mix of water/antifreeze in the radiator, plain water or water with water cooling additive i.e 'water wetter' ?

If you have a drain valve it will be at the bottom corner of your radiator. You should use a 50/50 mix of water and AF and a lot of also use Water Wetter. Do a quick search on "burping" your system as air bubbles can be a problem.

Anti-freeze and DISTILLED water. I use a 50/50 mix. Do NOT use plain tap water.

I use the pre-mixed 50/50 Anti-Freeze. I would be hesitant to use tap water in my Cobra. In fact, we don't even like to drink it.

Pre-mix is a huge rip off. You are paying high bucks for water. Get a good 100% antifreeze and a couple gallons of distilled water at the super-market.

I know, but I justify it by convincing myself that I'm saving the gas by avoiding a trip to the supermarket.
