Default Re: 59AB Cooling System Advice Needed from the Experts (not an overheating issue)

new thermostats may need to check several till you get a pair thats actually close . Curiosity how long since you re-torqued the heads a little added temp may have opened up a slight leak. When you refill leave the bottle empty and fill the rad run up to temp and see how much is in the bottle add a pint and let it cool leave o'night and recheck took 4 goes to stablise mine
