Re: Sludge in coolant, high pressure
Get yourself one of these, take thermostat out, disconnect one of the heater hoses and connect this valve in. Connect garden hose, turn on full, when it starts running clear, connect air to it and it will blast crap out. Repeat until you don't get any crap coming out. https://www.supercheapauto.co.nz/p/t...un/573217.html
