Hodge's new 4.2

[bsteveo]

PS: I'm a fan of the VDO gauges, super easy to ready, accurate, relatively cheap by comparison and easy on the eyes of a night time.

I'm really keen on these, finding them for around $280-290 for egt and boost set with all required hookups.

Why not use those billet senders and fit it to the bottom hose,
that will give you a more accurate reading IMO

Just another place for something to go wrong/ leak I reckon. The less joins and clamps the better....

Yeah they are nice, they're Rods *rocket55* . If I didn't have my redarc vdo would have been the go.

John Bennett says thats the best postion for the thermostat as well.
John Bennett designed the cooling system for all the V8 supercars
as well as most modern Aust built cars,
There is nothing this guy does not know about cooling systems
If it leaks you've done it wrong IMO.
A complete cooling system from him would be $400 for a hi-flow
water pump , he removes the tin pressed fan and replaces it with a bronze impellor
Die grinds any area cavitation could occur. He had systems to suit the petrol & Diesel
Patrols. sadly retired now, wish he was still working he is a one in a million type of guy
FYI megstexture has one in his top hose and had it in for years now without any problems

I'm afraid I have to disagree with the temp sensor in the bottom hose of a TD42.
If the thermostat sticks closed, you'll have little to no coolant circulating through the radiator and the bottom hose will have a low temp reading while the coolant coming from the head could be then boiling.
The current location of the TD42 temp sensors is in the path of the coolant coming from the head so it reads the hottest possible before it goes through the radiator.

Here some data , too bad no one has heard of him outside Vic

you throw away what you know about water cooled engines this guy it the Ducks nuts on all things water cooled
A lot of modern engines have adopted the thermostat in the lower hose from John's findings

[Hodge]

Bottom hose is straight out of radiator which would be "cooled" coolant. I mean logically if the coolant coming OUT of the radiator is hot enough for the thermo to open, imagine how hot the coolant is coming out of the block ?
On a TD42 that would just be asking for trouble IMO.

I was just looking at mine and i have studs on the lower housing...

[threedogs]

All I can say is John wrote the bible for water cooled engines.
Its a shame no one has heard of him
Its about taking the hot spots away from the head and concentrating the heat around all cyclinders.
but enough on that it too hard to explain
