What is a good coolant?
When I change out my coolant hoses I will need to replace the lost coolant. What is the right/best brand coolant to top off the level with? How would I bleed air from the system or will the surge tank take care of this for me?

i'm sure there are different opinions regarding which brand works...i usually get the 50/50 premixed coolant.
to bleed the system, you open your radiator cap, and then use a funnel to pour in coolant from that end. watch the bubbles flow out, repeat until no more bubbles appear.

50/50 Prestone will do you just fine. If you want to save a couple bucks use concentrate and distilled water. Make sure you get the mixture right so you don't freeze though. Better too much anti-freeze than too little. Use some water wetter too if you want. It helps from what I've read/heard.

Just be aware that part of the reason people use some coolant is for corrosion prevention so you may have to change that water out every 6-12 months. Water Wetter has some corrosion prevention in it's mixture and does indeed increase the amount of heat transfer that is possible between the fluid and the radiator core for increased efficiency.

what the heck are you thinking putting in pure distilled water???
even in hot weather states like cali, hardcore guys STILL add water wetter to their distilled water for corrosion resistance..... you think distilled water is good for storing cars in the nj winter? lol

I ran pure distilled water with 2 bottles of water wetter in a new radiator. I ran MUCH cooler with no issues... except I couldn't do the throttle reset since my ECT never went above 185 even when I drove it like I stole it.
Untill monday. It hit horribly freezing temps here (single digits during the day) and when I went for lunch.. I watched my ECTs climb.. 170...180...190...200....210...230....240... SHUTOFF! Scary..
Turns out the water that was in there froze inside the radiator. It had a bit of residual coolant left in the lines from when i replaced the radiator, but far from enough to avoid freezing.
(Yes, I know I should have drained and filled with proper antifreeze.. but I was too lazy after ripping apart a bunch of other stuff)
It's now actually running 50/50 with no problems. Radiator wasn't cracked, all coolant lines are dry.. whew.

yeah he's totally ignorant about why people run mostly water.... for cooling properties with some sacrifice on corrosion resistance in VERY hot conditions... this guys not even driving it in NJ winter but has 100% water HAHAHA

the amsoil stuff which uses propylene glycol is safe for you as a human too. normal antifreeze is made with ethylene glycol which is toxic, propylene glycol on the other hand is a key staple for many liquid medical products (syrups etc) certainly safe for you and your kids.
"best coolant" for racing is distilled water with water wetter.
best coolant for everyday driving especially in cold weather climates is probably a 50/50 mix. all antifreezes are essentially the same, they use ethylene glycol and a colorant and varying amounts of water (premix stuff). trust me i worked for a company that made the colorant for prestone antifreeze and it was no big secret. all these ingredients run the company pennies per gallon and they charge you $5 for it. go figure.
the amsoil stuff is different in that it uses propylene glycol which is "food safe". if that matters to you then go for that, if not buy what's discounted.
