water line air bleed, and hole in thermostat

[S0LJAH]

hey guys am running my water line from the back of my head

its going horizontal round the back of the head then under the inlet manifold then to the factory thermohousing which im mounting off the front of the inlet manifold below the throttle body and then up to the top radiator hose

have heard some poeple take about air bleeds

do i need one in the back of the water pipe?due to the fact it will drop down to go under the manifold
the rad cap will still be the highest point of the system

also anyone done the drill a small hole in the thermostat trick to allow a bit of flow through it so the water in the pipe circulates allowing warm water from the head top reach the thermosatat easier and open it rather than waiting for the water in the line to heat up, by which stage the water in the head would be way too hot

thatsa good idea

holes isnt for the air being trapped is to do with the water not heating up in the line well enough but if the hole will help with air trapped in that it will help the air flow through ill give it a try should kill t2o birds with one stone then

Water conducts heat pretty well. Between conduction and convection the warmth will make to to the thermostat without much delay.

ok ive heard of people having problems where the water in the head is boiling before the thermostat opens as it hasnt conducted the heat well enough

only going by what ive heard

my thermo housing is right up the front under the inlet manifold/throttle body (still using rear exit so pipe runs along/under side of manifold)

you just find the highest point where air can collect in your system and bleed off the air, use the heater hose at the firewall , just pull the hose off a little bit until you have coolant come out and purge the air out. ( turn your heater on full heat)
boiling coolant in the head is an extreme condition that souldnt really happen if you keep the coolant system under pressure ( meaning radiater cap)
run the engine with the cap off until the thermostate opens , you will have a little coolant come out and then notice coolant drop in the radiater, that will tell you the thermostat opened, then top off the fluid and put the cap on

He's not talking about bleeding the system, but having a small bit of flow to the thermostat.

If you're so worried about it drill a hole in the thermostat. They usually have a hole in them with a little floaty thing for just this purpose.

with a little floaty thing for just this purpose.

"floaty thing' ??????????????

last time I saw a 'floaty thing' , I had to make three trips to the ' free clinic'

somethin to do with african mokey virus

its a technical term.
