Was slowly losing coolant. Definite pink sludge at weep hole of water pump, replaced it. Bled air out, drove great for almost two hundred miles then coolant reservoir empty. Thought it was air pocket, filled reservoir, about another one hundred plus miles found it empty again. Pressure tested, not losing pressure, not able to see any wet areas. But did see crust at top of radiator along where plastic and aluminum meet. Replaced radiator and cap (Denso). Drove round trip today of ninety miles and two hours, coolant reservoir almost empty again.
No evidence of oil in coolant or vice versa. No white smoke.
have the same problem?
