Tips for getting air out of Intercooler/Heat Exchanger?

[NatJoo]

Installed a Roush/VMP system a few weeks back, but not getting any flow of coolant through the heat exchanger. I can feel the pump running but the tank is super still so do not think anything is flowing. Any tips for troubleshooting this. Assuming an air pocket somewhere. Have removed the top hose and blown into the tank and it pushes coolant out. I'm a bit stumped unless the pump is running but bad. Brand new pump.

Not sure what this is, but is a hose crimped/pinched/too small? Not sure why you'd run coolant through it, either. Even on a hot day, the ambient temperature should be way less than coolant.

Have you tried squeezing the hoses while the pump is running?
Lifting the fill point can also help.
Placing the system under vacuum is another option.
Also, parking the car “nose up” may help.
Finally, it’s been suggested that taking the car for a drive can actually help. I’m guessing the movement of the liquid may force some of the air pockets out.

Thanks for the posts. Found a video and had a bit of a duh moment. On the 2015+ the pump mounts with the feed on the bottom facing up. Fix is to unbolt it and let it dangle and the air pocket works itself out as the bubble wants to rise.

This video help me.



On the tvs blowers the heat exchanger is a separate coolant system than engine coolant. Temps run much cooler.

Is something cooling that coolant? Otherwise, it's still ambient temp.

The heat exchanger in front of the radiator?

But that's still ambient temp. There is no "wind chill".

Yea it doesn’t go below ambient.

Why would you expect it to go below ambient?
I’m not sure that I follow

All those will get you is fast ambient temp.

Then what's the point of all the extra plumbing? Just run the blower through an inter-cooler. For all that, I'd want the blower's coolant chilled. A Ram owner I know ran the turbo output through an ice chest under the hood. Even on a toasty Florida summer day, his air temp was probably < 70. Also went through a fair bit of ice, I think.

Because some people want to drive their cars around....? Ice tanks primarily are only really for track use, a heat exchanger is used for street cars.

Are you familiar with how a TVS blower is mounted? It is inches between the intercooler and intake ports on the heads. Intercooler sits in the valley between the heads...is cooled by the heat exchanger at the front of the car. It can be debated if the fans are beneficial, but the system needs liquid cooling. Ice boxes are fine for drag racing but not going to do anything meaningful on a street car.
