Hi, I'm having a problem locating the "petcock" to drain the engine coolant for a 1997 Toyota Tercel. please help.

Hello,

The knock sensor is usually located in the side of your engine block just under the exhaust manifold. If your standing in front of the car (Since Its Front Wheel Drive) It should be almost in the center directly in front of you.


I hope this helps to answer you question. If it does please show your support by clicking the helpful button. Have a great day!

Radiators usually have a valve/petcock located on the engine side of the radiator down at the bottom. Valve turns like a bolt and antifreeze coolant will drain out into your drainpan. Use care as coolant is poison and needs to be disposed of properly. After radiator has drained, retighten petcock and fill to the appropriate level.

Good luck.

Check this VIDEO for removing, cleaning, and reinstalling the EGR valve on my 95 Toyota Tercel.




Hope helps (remember to rate this answer).

Hi,
There are no petcock valve on toyota camry.
What its a plain radiator cap that has a valve in it, pressure can be activated at certain point and the coolant goes through the coolant reservoir.
You mean the radiator drain plug? you would see that plug underneathe that radiator assembly, wing nut type plastic made, can be loosen by hand or a pair of pliers!
Hope that was your looking for!
Thanks for using Fixya!

just remove lower radiator hose,there is a drain though its at the bottom of radiator on drivers side

number 1 cylinder is located closest to fan belts if belts are on left then its the first spark plug from left of engine or vise versa

drain the coolant out completely first, then close the valve at the radiator and refill the radiator(you do this with the engine turned off) make sure that it takes atleast a gallon of coolant and if it does not then yo have a clogged up radiator, replace the radiator before you do any thing else

The spark plugs are where the 4 wires attach at the flat silver/gray area on the engine.
