gents,
new wrench here. bear with me please.
i just pressure tested my radiator with a snap on loaner from a local toyota tech.
as i recall instructions were heater to ON position, verify the heater control valve is fully to the left/DS (i double checked it). and then 17 PSI and see if it holds.
i’m used to motorcycle tires and i didn’t get much pressure on it but before i continued i checked the gauge it appeared to be up at 80 PSI so i stopped. quickly. i see now i was at kilopascals which is roughly 12 PSI which held fine.
two questions.
1. i had to /file/ some of the vertical edge surface of the cap off (seems fine since it seals at the interior) but it was still a super, super tight fit so i am a bit sketched about doing it again since i don’t want to bust the flange. i don’t know why the flange on my radiator is so damn tight. but i’m wondering if i need to retest. in which case i will probably take a little more off the flange.
2. i had a whole lotta coolant spurt out of the adapter when i pulled the pressure tester off of it. it /appears/ to have come out of the overflow reservoir. what is going on here? do i need to let it sit 20 minutes to let it flow back to the reservoir? should i have a pressure release on the gauge (doh!)?
someone mind clarifying the physics for me so i know how to do it properly next time?
honestly i was so focused on being gentle with that flange i didn’t quite catch what was what.
THANKS
jon
