plumbing headache

[hurleyshotrods]

hi guys ive got a t1 bug fitted with a 1.9 dg engine,
car was bought as an unfinished project, engine was allready installed and plumbed in,
after getting everything else done and finally getting to use the car a few weeks ago its seems to run hot,
now ive spoken to a few people and got some good info and found that not all the water outlet feeds are connected to the return flow to the radiator.
i dont have a thermostate or overflow tank or header tank, its running twin carbs so theres no pipes for the manifold.

whati do have is, feed from top hose on rad to water pump. feed from bottom of waterpump to right hand head,
the feed to the bleeder ring is blocked off by a blanking plate, and also found the 2 feeds at the front of the engine are feeding to each other so theres not a proper flow there,
my plan is to connect all the outlet feeds back to the return hose to the rad including the one that should lead to the bleeder ring,

now my headache starts with the radiator itself, according to how mine is set up and how it reads in the haynes book of lies,
the water feed to the waterpump comes from the top hose, (is this correct as i would have thought with gravity etc that the feed to the pump would be best from the bottom hose and return feed to the top hose.) ??
im getting an average temp of 105 as its set up now so once ive sorted out connecting the pipes up as they should be then it should run cooler, as it will have a decent flow,

You need to have proper flow through the front jack feeds and then out of the heads, front and rear.
The standard hoses/fittings have specific sizes to adjust flow in different areas.
I'm guessing you have the later style system as you are running without a thermostat.
The later style has the thermostat at the rear and uses a distribution point to centralise water feeds from/to the engine.
The earlier style is much easier to fit to a T1 as it has the thermostat body by the pump.

Whatever solution you go for it's important to have a header tank or burp tank fitted prior to the water pump feed or you risk air locks.

I run the early style system.
The two front (pulley side) water out's use the stock metal pipes to return to the thermostat.
The two rear pipes are joined with a T piece, then to a heater in the car, then back through a burb tank and finally into the top pump feed.
My radiator is up front and has it's own header tank to aid bleeding.
I struggle to get over 90 degree's in any weather so it's a setup that works well.
