Where to connect heater hoses on 134 engine

markct · Oct 20, 2016

As I'm working on installing a cab I got
wondering where did heater hoses get
connected to the engine generally, I see
no ports like a automotive engine. My
thought was to add an 8n thermostat in
the hose and remove the original one
then tap into the side of the thermostat
housing for one feed then return to
lower radiator hose with a T

Without drilling any new holes in your engine block, I think what you proposed is your best option. You could source your hot water supply from the temperature gauge hole, but then you'd lose your gauge. You can't tee it there either, unless you plan to circulate hot water through your heater core all summer long.

let me look at my 660. It was bought from up north and had hoses on it that I didn't use/need for heat.

let me see if I left them or removed them.

Thanks, and it seems the Ford 134 uses a different thermostat bolt pattern than anything else ford, all the Ford truck engines and even the Ford from a Hobart welder I have here all use 3" bolt spacing yet the 134 seems to be 2 3/4

Front of head to block drain

I'm struggling to see where exactly that top line is ported. It looks like it goes straight into the cylinder head just before the thermostat. If so, I fail to see how that arrangement count circulate any water, since both ports would be on the pressure side of the water pump.

Good point bern, I thought about tapping the head there but was nervous! Maybe I will

When I got my 660 it was there and t-d together with a stop valve in between. Block drain is the connection on block..

Ps, I scraped around, on my 941 & its head has a plugged port up there as well. Couldn't see on my 850 due to the loader frame.

Given that one port is on the head, and one on the block, any flow restrictions between will allow for water to flow the a less restricted heater core.

Bern · Oct 21, 2016

Hmmmm...I'm not sure about that. If there is any difference in pressure, it won't be much, and you certainly would not have very much flow through a heater core.

souNdguy · Oct 21, 2016

I bet with those slotted ports blocked as the new he's gaskets are doing, the flow leaving the he's may be more restricted than originally designed

The biggest restriction in a cooling system is a closed thermostat. This would balance out the pressures in the block and head.

Take a look at any heater core plumbing in any car or truck. One goes to the pressure side (cylinder head), the other goes to the suction side (water pump inlet). I still don't see how your idea would work.

If you can find a propane powered tractor in a scrapyard, they have extra ports on the upper neck and pump to connect heater sized hoses.

markct · Oct 22, 2016

Yes and you would want heat before the thermostat opens of course, that's why if I get too nervous about tapping my head I plan to remove the original thermostat and add one in the hose then tap the gooseneck

n Soundguy tractor's connections: perhaps for an electric block heater?

Tapping the gn, will still put you aft of the thermostat

markct · Oct 23, 2016

Not if I remove the original thermostat and replace it with an 8n thermostat in the hose

souNdguy · Oct 24, 2016

maybee.. dunno. when I got it, it was t's together and has a scre in cutoff. I left it that way in case I might ever think up a
future use for it.. never did.

You could tap in to the block drain or for hotter water use the port in the head then return it back to a tee in the bottom radiator hose.
