Removing radiator to the rear

[terrybullwon]

Its a race car so no heater box.

Rail goes to the rear and thermostat is the return

[my2000apb]

do you have the old heater holes in teh head plugged or looped?

[terrybullwon]

heater holes?

[my2000apb]

heater holes?

yeah whatever you call the two coolant inlet/outlets on the back of cylinder head

[terrybullwon]

This is the question, do i join from the thermo stat housing or not?

[terrybullwon]

You really mean on the cylinder head? The core plug on the head should be in your only left with the hole in the Block.

Well its done.

But from speaking to atleast 6 different people there are many ways to do it.

i've seen a different one as the aux pump flows coolant in the opposite direction?

can leave the thermostat in but drill a small hole through it like 6mm dia, then test it so see how it behaves, ive had a few audis with the thermostat stuck open and fuel consumption is ***** and they never really get up to temperature. i have an electric water pump wired up to my vems rad fan output, and the rear fans are contolled by a normal thermostatic switch with a manual overide. i had one of those davis craig thermostatic contollers but they dont seem to be great so never bothered fitting it

you need to run a small diameter pipe from the top of your rad to the expansion bottle, prob as well to run a small one from your thermostat housing aswell as these are the areas most likely to be air locked, also makes bleeding a lot easier
