I am attempting to drain the engine coolant but the petcock isn’t budging. Does anyone have any suggestions on how to loosen? It’s plastic so I want to be cautious and not break it. I found that you can get a socket for it but I don’t know which one would fit. Thanks! Suze
The first time it will be tight. You could buy a replacement just in case or at least have one available at the time.
A pair of pliers or adjustable wrench can help. Don't clamp hard, just snug on the flat part, carefully turn (counter clockwise).
Use something like this, put the "wing" of the drain cock in the slot and turn it. Additionally, using a 1/4 inch hex driver ratchet handle will help to turn the bit. Georgina must have "man hands" to be able to turn a drain cock that has been stuck in place for years without being moved by hand. Especially, since reaching the stopcock will force you to bend your wrist and fingers into awkward angles where you can't get any torque applied to turn anything. Posted via the PriusChat mobile app.
Thank you all for responding! I really appreciate the suggestions. I tried again after posting and was able to loosen from a different position underneath using my right hand instead of left. It’s probably a girly strength issue lol Thanks again!
I drained to replace along with inverter coolant. Have taken out intake manifold to clean along with EGR pipe and cooler. I also replaced pcv valve while I had manifold out. This thread EGR cooler cleaning-Prius V 2016 | PriusChat helped me get out the cooler when I thought of giving up.
I also drained and replaced the ICE coolant while doing the EGR circuit cleaning as well. Now it will be on a 50K cycle of coolant replacement and EGR cleaning since the coolant change interval after the factory coolant is replaced is 50K. This is due to the fact that some of the original coolant remained in the heater core and hoses, so subsequent coolant drain and fills are on shorter intervals. Posted via the PriusChat mobile app.
No sell it before it puts you in the poor house. All gas $$$ will be lost when the car craps out on you.......and it will...............
Hey I've got a pair of vise-grip style oil filter pliers I keep in a drawer in the kitchen, primarily for breaking loose the lids on spaghetti sauce jars...
My sister with arthritis recommended this handy jar opener. It is very easy to use and lightweight, but gives you leverage on the most stubborn caps/lids. 4000+ positive reviews. Posted via the PriusChat mobile app.
Here's another picture of how it looks opening a jar of spaghetti sauce lol. Posted via the PriusChat mobile app.
