Question about 1994 Toyota Previa
The van overheats after driving about 5 miles but water is not leaking anywhere until it starts overflowing.

- Check the radiator cap for proper sealing.
- Blow air from outside and inside of the radiator to clean the fine dust accumulated in the feathers and fins.
- Check the radiator for clogged inside. Clean the radiator after disassembling it.
- Check the water pump belt for looseness or wear.
- Check the thermostat valve.
- Check the cylinder head gasket or re-torque the cylinder head bolts.

Ok first check the water pump and if that is ok sounds like the head gasket blown, look for water in the oi, thisl will be like a milky colour

The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.
