To flush a Toyota Previa radiator, first drain the antifreeze in the radiator into a bucket. This is done by turning the valve at the bottom of the radiator. Close the valve and add a radiator flush product purchased at an automotive parts store. Follow the directions on the bottle of flush. This usually means running the vehicle for a certain amount of time and then draining the radiator again.
the reason it wont circulate is cuz u radiator is clogged or plugged flush it or buy a new one
To flush the cooling system of a 1992 Toyota Previa, start by ensuring the engine is cool and then remove the radiator cap. Drain the old coolant by opening the drain valve at the bottom of the radiator and allowing the fluid to flow out. Next, fill the radiator with a mixture of water and a cooling system flush solution, run the engine until it reaches operating temperature, and then let it cool before draining again. Finally, refill the system with fresh coolant, ensuring to bleed any air out of the system by running the engine with the radiator cap off until the thermostat opens.

Toyota Previa was created in 1990.
To flush the radiator in a 1989 Toyota Cressida, first ensure the engine is cool and then remove the radiator cap. Drain the old coolant by opening the drain valve at the bottom of the radiator and allowing it to flow into a container. Next, fill the radiator with a mixture of water and a radiator flush product, running the engine for about 10-15 minutes with the heater on to circulate the solution. Finally, drain the flush solution, rinse with clean water, and refill with the appropriate coolant mixture.
Thermostat could be stuck shut. Or the water pump could be failing.
