2007 Toyota Sienna Q&A
2007 Toyota Sienna Question: Toyota claims slow leak rear head gasket seal. Coolant . Pressure test ?
I have been to 2 Toyota service centers. Both indicate upper rear seal slow leak coolant. Neither mentioned pressure testing the system to determine the extent of the problem. Considering the estimated cost of the repair , I can't understand this. What should I do ? Tks PDV - pdv
most times is very visable were headgasket is leaking due to water stains at head gasket. im sure they are correct - globalhelper
