there isnt one after 1996
Flushing sometimes frees up mineral deposits that then clog up your heater core. My mechanic told me to never flush a Toyota as the heater core was low in the engine. That is, only drain and fill when doing a coolant change to prevent dislodging the deposits.
probably the heater core is clogged
you probably need to flush the coolant system. GM claims that the coolant is good for a ridiculous number of miles, but it is not so. The coolant breaks down and forms large clumps which will clog up the heater core. You may need to flush several times to get it all out.
Drain and properly dispose (recycle) the old coolant. Put one bottle of Radiator Flush(from am auto parts store)in the radiator and refill with water. Run the car a idle(leave the heater ON to flush the heater core)for approx. 5 minutes. Drain and properly dispose of the flush liquid. Refill radiator with 50/50 mix of coolant and water or all premixed coolant.
go to the auto store and buy some prestone flush. instructions are on the back. basically you drain your radiator, pour in the flush, refill the system with water, run the engine with the heater on high for about 15 minutes, then drain the system again, refill it with 50/50 coolant.
the 2000 celica gts does it in 6.6
Your 2000 Toyota Celica has a chain and not a belt. The chain requires no maintenance.
Dex coolant is very popular in newer vehicles. Dex coolant is good for 50,000 miles or 5 years which ever comes first.
2000 Toyota Celica have timing chains.
yes
Drain plug is called a pepcock. it is located at the bottom of the tank part of the radiator. To fully flush a radiator, you need to buy a flush kit. You can get it at any auto store. instructions are in the package.
