There is a coolant bleeder valve in front of the cylinder head. This things plays hide and seek with me when i am looking through the spare parts catalouges and drawings. Anybody can point at it?

...and it doesn't take much to cinch it down- you don't have to torque it with the power of Hercules. Think light touch.

just had to throw that in there.

Hidden at the intake manifold. Thank you sir!

Yes, allways handthight or really with the small 1/4" torque wrench by the book. The conical sealing on these bleeder nipples dont need much force for a 100% perfect seal. Same for breake bleeders.
Many hobby mechanics dont get it and wrench them down gorilla style. Back then when i have serviced motorcyles of friends i sometimes had a hard time with theses brake bleeder nipples.

yeah, I learned this about 30 years ago on my first car...2 hours of frustration later, I was schooled on the virtues of the torque wrench

As a hobby mechanic, i use my torque wrenches extensivly, for almost everything. Its a hobby, take your time and do it right.

Every time i service brakes, i remove the bleeders completly and clean it with a brass brush. I coat the thread with anti size paste and thread it back in. When i am finished with changing the brake fluid, i try to get rid of the brake fluid left in the bleeder. As brake fuid attracts moisture, it can cause corrosin. I simply grab a spray can of my favourite penetrating oil and spray it down in the bore of the nipple with the long, thin plastic straw nozzle. Place a rag over it. Brake fluid gets flushed out and is replaced with oil. Done. Dont forget the rubber cap. Never had problems with the brake bleeders again. They open effortless 2 years later when i service the brakes again.

2 Minutes extra work, well invested....

Yeah, bolts which are not solid, like banjo bolts --- it's not a good idea not honk down on them when tightening.

I mean, it'll hold pressure just being finger tight, you obviously don't need any ugga duggas.

Anybody knows the thread size and length of this bolt?
