I'm in the process of installing a right-angle fitting into the blanking plate of my cylinder head. The idea being to get the same effect as fitting the rare ST blanking plate with outlet (i.e. equalised cylinder head temp).<br>
<br>
Can anyone tell me how the plumbing goes from this fitting into the cooling system?<br>

workshop manual shows the correct setup I'm sure theres one on the net somewhere.................

<p></p><i></i>

Take a look on rimmers web site it's shown on the TR7 cooling system. I followed it when doing mine it's quite simple.

Ok, just had a look at Rimmers - found the following pics<br>
<br>
<!--EZCODE IMAGE START--><img src="http://www.rimmerbros.co.uk/tr7/images/22b.gif" style="border:0;"/><!--EZCODE IMAGE END--><br>
this one shows the adaptor plate at the rear of the head<br>
<br>
<br>
<!--EZCODE IMAGE START--><img src="http://www.rimmerbros.co.uk/tr7/images/24c.gif" style="border:0;"/><!--EZCODE IMAGE END--><br>
this one is heater assembly<br>
<br>
<br>
<!--EZCODE IMAGE START--><img src="http://www.rimmerbros.co.uk/tr7/images/25.gif" style="border:0;"/><!--EZCODE IMAGE END--><br>
this one is heater hoses<br>
<br>
so does the hose from the adaptor plate go into the heater matrix? then what? I must be missing something (haven't had any coffee yet <!--EZCODE EMOTICON START :x --><img src=http://www.ezboard.com/intl/aenglish/im ... s/sick.gif ALT=":x"><!--EZCODE EMOTICON END--> )<br>

The hose does indeed go from the cylinder head to the heater matrix the other heater outlet then goes to a t piece that connects to the inlet manifold and the water pump cover. It certainly makes my heater very hot but turning on the interior heater in severe traffic does help cool things down well.<br>
<br>
I used a brass fuel supply t piece this replaces the old heater h piece and as its brass no corrosion.

Thanks alan (?),<br>

I can see how this sucks the hot coolant out of the back of the head straight into the heater matrix (hence hot heater) and from the Heater into the water pump. When the heater is on cold and thus 'shut off' form the circuit, presumably the hot coolant exits the head via the manifold and gets sucked straight into water pump via T piece. Do I f'low correctly and does it make much diff the the overall running temp of the cooling system

I was reading my factory manual last night (as you do) all about the heater actually and to my understanding it seemed that the coolant was always flowing through the heater matrix, but you only felt hot air when you opened the appropriate flap...<br>
<br>
Of course that goes against the instruction to "turn heater controls to hot" when draining the cooling system...<br>
<br>
Think i might read that bit again... <!--EZCODE EMOTICON START : --><img src=http://www.ezboard.com/intl/aenglish/im ... ohwell.gif ALT=":"><!--EZCODE EMOTICON END--> <br>

There's a valve that shuts off the water flow thorugh the heater matrix when the control lever is set to cold.

<p></p><i></i>

any sprint owner has ever turned of the flow thru the heater!<!--EZCODE EMOTICON START :) --><img src=http://www.ezboard.com/intl/aenglish/im ... /smile.gif ALT=":)"><!--EZCODE EMOTICON END-->

<p></p><i></i>

Yup i picked up on the water valve on my second read through.<br>
<br>
I've had a thought about this mod - now i believe alan's setup looks like this:<br>
(<!--EZCODE FONT START--><span style="color:red;">T-piece</span><!--EZCODE FONT END-->)<br>
<br>
Heater<br>
| |<br>
| \__ Head<br>
|<br>
<!--EZCODE FONT START--><span style="color:red;">|-</span><!--EZCODE FONT END-->.<br>
| |<br>
| |<br>
WP Manifold<br>
<br>
with H piece removed so water only flows from rear of head when heater water valve is open.<br>
What i thought would improve upon this is:<br>
(<!--EZCODE FONT START--><span style="color:red;">T-piece</span><!--EZCODE FONT END-->, <!--EZCODE FONT START--><span style="color:blue;">H-piece</span><!--EZCODE FONT END-->)<br>
<br>
Heater<br>
| |<br>
| <!--EZCODE FONT START--><span style="color:red;">|--</span><!--EZCODE FONT END-->-- Head<br>
<!--EZCODE FONT START--><span style="color:blue;">|-|</span><!--EZCODE FONT END--><br>
| | <br>
| |<br>
WP Manifold<br>
<br>
So that water can always flow from the back of the head whether heater water valve is open or not??<br>
<br>
What do people think?<br>

Turn a heater to cold in a Sprint, nahh, Sprint owners too smart, if you've paid for the heater, you might as well use it <!--EZCODE EMOTICON START ;) --><img src=http://www.ezboard.com/intl/aenglish/im ... s/wink.gif ALT=";)"><!--EZCODE EMOTICON END-->

Theoretically, the T Piece & H Piece would allow the hot water to exit the head in two places, the rear of the head and the manifold. Dunno how one works out the dynamics of coolant flow, so perhaps one doesn't. I'm tempted to try some experiments through the summer. Creative diagram, nice one <!--EZCODE EMOTICON START ;) --><img src=http://www.ezboard.com/intl/aenglish/im ... s/wink.gif ALT=";)"><!--EZCODE EMOTICON END-->

Ok, well i guess i'll designate myself guinea pig for this one - keep you posted...<br>
