Bleeding cooling system...do not overfill...

[Ricky Bobby]

OMG all my radio guys advertise Dinovite every day on the radio ( you can imagine what station I listen to on Sirius) - D-I-N-O-V-I-T-E.com (woof)

Its funny how their bodies bounce back and amazing - Chad had to do 5 rounds of chemo spaced 3 weeks apart for each back about 4 months ago after his radiation was done on his Grade 3 tumor site, the chemo rounds were for any potential cells remaining that could metastasize. He actually got some black freckles under his white coat which I thought was hair loss, but his hair is thicker than ever, he just has some "freckles" - I'm going to put up a recent pic - but he is doing great, and as sad as it sounds, its wonderful news that we only have to do radiation this time and we can be done. The chemo really tired him out and made him extremely picky of an eater. 2 weeks after he was done though, back to 2 mile walks a day.

If you overfill the pressure will build to either lift the 2bar (29psi) cap or burst / break something. An older system will typically have a part failure before the cap lifts. Many install a 1.2bar (17psi) cap. Better to slightly under fill than overfill.
A 50/50 glycol mix at 1.2bar has a boiling point of 270F. A 50/50 glycol mix at 2 bar is about 295F ( couldn’t find the exact number so used the estimate of 3F/psi from 280F@24psi)

Where would one buy a 1.2bar cap that fits our reservoir?

So I guess I'll fill it up and then siphon some out so the level gage reads right. I believe I did that last time I had to fill it up. I don't want replace the ET just because of overfilling. Thank you.

I’ve been using an e30 1.4 bar cap for 5 years now. I feel way safer with it. The only retarded car in the world with a hose / expansion tank / radiator / valley pan exploding 2 bar cap.

Cool, thanks for the pointer! Got it from dealer for only $17.
