Fury Radiator Help

[pigeondave]

I use a raceline water rail with any issues.

Thats good to know.

I was just pointing out to the OP that (as far as i know, and i don't know a lot) the raceline water rail does not have a bypass like the standard thermostat housing, so the water in the engine must heat up and the water in most of the rail before the stat opens in the raceline rail. this can only happen through conduction as the water is not flowing.

The stat is about 2/3 along the rail.

when this stat opens the cold water in the rad gets to the engine and gives a bit of a cold shock to the engine. This all comes about because there is no bypass in the water rail.

As i have stated some people drill an 8mm ish hole in the stat to allow a little flow during warm up.

If the bypass is not needed why is there one on the standard ford item? do they put it there for fun?

I have the standard thermostat housing on the back of the engine with a 90 bend that goes to a metal pipe that goes under the exhausts then a flexi pipe to the rad.

I believe that the raceline and dunnell water rails are used where the engine is so far back that its difficult to use the standard thermostat housing. This would also mean that the coil pack needs moving.

I dont need one on the Fury as the limiting factor of how far back the engine can go is the bellhousing/pedalbox area.

OP tims31

main point to note is in the raceline rail if the stat is closed and you dont have a little hole the water isnt flowing round the engine.
I believe that the dunnell one has a bypass.

Then again if the raceline one does have a bypass all the above is bolx.

(please note Im a bit of a perfectionist when it comes to the Fury so i am a bit picky)

For utter confusion read this

ive read it twice and still dont get it

Thanks for all that guys.

I will be using the standard housing on the back of the block, as you say there is enough room on the Fury for that and the coil pack with the bell housing restricting the movement backwards. I have seen some run the large outlet from the thermostat housing over the exhaust manifold but I had the same thought about being higher than the housing and having possible air lock problems. I guess running it under the manifold and off to the top hose on the raidator it will be then.

Thanks for the input.

The way to run a RACELINE water rail , is firstly (as you've said)cut off the little valve sphere then drill out to 8mm or more . Secondly to use an expansion tank on the bulkhead with it's level at the highest water point within the engine . Remove the pressure cap from the thermo on the water rail and fit to the expansion tank then fit a standard non pressure cap to the thermo. Mine's run that way for over ten years. FORD's reason for the bypass is for engine efficiency hence the 5/8ths outlet to rad' . SIMPLE's
