My cooling system

Let me get some feed back on this. I took my gas tank out, built some custom brackets, and moved it up near the dash. Then I found a radiator that fit over the hole left by the gas tank. It's lying over that hole, with two fans over it, pushing air. The coolant lines run up before the front axle and connect to the rad. Soldered the filler neck shut, added an air bleed. I have the tire well cut out and I'm trying to put a sort of inconspicuos scoop up front to channel air under the hood. I'm gonna make some sort of air dam after the rad so air isn't blowing through the dash. Think I'll have enough airflow? BTW subaru EJ22 out back.

Re: My cooling system

this is interesting to see. i put mine in the wheel well and made some shrouds, ducting the air from the bottom front of the wheel well

Re: My cooling system

Your rad looks plenty big .

Do you add water in the rear with the engine ?

You may have to make some duct work for tooling
down the highway.

It does look good the way it is now.

The rad in my Super Vert sits upright,slightly higher than
the engine,just behind where the Super beatle grille
used to be.

Keep us posted as to water temps....

Re: My cooling system

The spare tire space up front has been cut out, and plenty of air comes in. I need to build some sort of firewall after the rdiator to keep air from coming through the dash.

So far, water temps have not been an issue. of course, it hasn't been hot outside yet, but driving on the interstate rarely brings the temp even close to 180. It generally hangs out at less than 160. A minute before getting off of the interstate, I'll turn the fans on, the temp might go up to 180-200 when you kill the airflow like that. it drops fairly rapidly, though.

I fill it at the back, it has a vanagon pressure tank back there. Yes, it takes a while.

Re: My cooling system

this may sound like a stupid question, but how does the water flow in thsi sort of setup? in a traditional radiator setup (standing vertically) as hot water rises, the water is pumped from the engine into the top of the radiator, and as it cools and more hot water comes, it is forced down to the bottom of the radiator then back into the cooling system, guaranteeign that only the coolest water available makes it back to the engine. how does this work when your radiator has no top or bottom?!?

Re: My cooling system

Water is forced into the cooling tubes, no matter it's position. So as long as there is airflow, I don't think it's an issue.

85 degrees the other day. Was on the interstate going 80 for half an hour, turned fans on 1/4 mile before exit, and stopped and sat in traffic. Temp never went over 195. Works for me!
