Re: water boiling from reservoir
rad cap /thread lol
usually when coolant boils out into the reservoir it's because there isnt enough pressure from the radiator cap to keep the boiling point of the coolant raised.
Its physics ;p
water boils at 100 deg. C at sea level, increase altitude (lower pressure) and water boils at a lower temperature, decrease altitude (increase pressure) and the boiling point goes up.
The rad cap recreates this effect.
If the rad cap doesnt fix it, try using a lower temp thermostat, also if your fan quit, check the fuse and fan relay and use an ohm meter on the fan to see if it is going to kick the bucket, if so, buy a new one.
Hope that helps.
