cooling issues..., fine when driving, spikes when stopped. Options

So, got my conversion finally road worthy and have noticed that while I am driving around, the car stays at around 200 F. when i stop, or let it idle in my garage... the temp slowly climbs and doesnt stop (i shut it off around 230 F). I am assuming this is an issue with my fans.

I am running a front mounted radiator, using 2 push-style fans. A few things that i think may be wrong...

-There is no shroud around the fans... just the shroud that seals the radiator to the front (since they are push fans, they are mounted on the front side of the radiator, in between the radiator and the nose of the car)

- there is about a 1 1/2" gap between the fans and the radiator (this was just the way that ended up working for mounting the fans)

anyways, i am pretty sure that the cooling system is working (no kinked lines, thermostat working, fans do turn on) as indicated by driving and the temp staying cool, there is just something not working when i stop moving. let me know what you guys think.

You could try the the Bong method to get the air out and water in to teh cooling system the Bong is a tall pipe, maybe three feet, of PVC pipe, maybe 2 inches diameter, it is attached to the top of the filler hole via a rubber plumbing sleave with two hose clamps to make a tight seal to teh Bong. the bong can now be filled with coolant, becuase of teh tall sixe of teh bong, it will give the filler head pressure to help force air out.

this works great on a vanagon, which are well known for trapping air no need to jack up the van nor hybrid 914 with the bong.

the bong idea is compliments of the samba.


for my 914 Buick car, before I had the bong, I used a steep, very steep driveway to help get the radiator higher and got the air out, took several trys


give the bong idea a try, cheap and easy to make, and it does work very well on vanagons which have simular probelms with high spots trapping air.


good luck
