My vmount with no AST is a pain to bleed. I use the funnel (really its a must have), and let the car idle for 20 minutes or so with the funnel 1/2 full. Then I let the car cool for 4-5 hours with the funnel still attached. The coolant gets more dense as it cools and more air bubbles come out during this process. Also, most of the coolant will drain back from the funnel durring this cool down avoiding air pockets forming as it cools. Squeezing the radiator hoses now and then during cool down helps out as well.

Good to know. Does the Ast make it easier to bleed?

Im also going to get a set of the defi gauges so I can report more accurate temps, Ill keep everyone posted. Obviously Water temp is one, what are the other two most important gauges? I have a boost gauge already.

If you get a PowerFC with commander, you can see all the cars sensors accurately instead of having separate gauges.

Oh, well then there you go, I have been waiting to install my vmount before I send this off to Rotary performance to get a map put on it.



Thanks for the advice, I knew it had sensor readings I just didnt know how accurate they were.

I highly recommend a Datalogit. If nothing else, it will allow you to load your own maps, and save them after its tuned.

"Just before the vmount my overflow tank was barfing coolant and overheating". You had the problem before the v mount. That is not the problem. Your coolant seals are going. You can run them for a while but it will get worse. Eventually you will need a rebuild.

I think it was my ast hoses. They would take coolant in but wouldn't pull it back to the engine.

I pressure tested my system today. From the ast cap it held 15lbs, no leaks, bubbles or drops in pressure.

Does the ast prevent testing from the coolant fill cap?

Glad you figured it out!
Bleeding the systems can be a pain if you dont own a coolant vacume chamber filling system. They are very pricey but pays for its self for a rotary shop.

im having somewhat the same issue with bleeding my system as of last night i spent near an hour trying to bleed all air out of the system. what im havin issues with is really just getting all the air out. it seems everytime the thermostat opens the coolant is boiling to the point where it just spits it all out. keep in mind i have no ast,overflow just the radiator and main filler cap. any suggestions?
