I've just ordered 7L of waterless coolant as i've nearly finished my rebuild. The coolant system has been dry for around 7 months so hopefully i wont need the flushing agent.

My question is, do i still need to run a swirl pot as there will be no pressure in the system from having no boiling water. Spec is stage 3+

 

Personally I'd not use it at all. It makes the car run hotter than it would on normal coolant.

 

I still have the swirl pot on my Escort Cosworth & have no problems with the waterless coolant fella

 

Cheers matey.

Was trying to get away without fitting the swirl pot as i've got a 4WD header tank with no inlet for the top of the switl pot

 

I use Evans waterless coolent too. Excellent stuff. I have the swirl pot just because it was there before.
