Ej soob cooling tip

[russ]

Mate has a tip for getting the air out of the cooling system on the soobs.......

pull the plug off the heater hose outlet that is on the water pump, push on a hose that is long enough to up to the top of the engine, push a funnel into the hose, fill the funnel quickly with water and keep it full while the water is working it's way into the cooling system, when the water stops leaving the funnel, then get someone to hold the funnel full of water, then you rip off the hose at the water pump, jamb your finger into the hole, then jamb on the plug again.

rekins he tried this way 3...4 times, worked every time.

Good luck................. :hug:

Are you talking the ej series Russ?

sure am

Ok Russ, I just can't seem to remember a plug on the heater hose. RAF and other ej-series engine users say that you must have the heater hoses connected to get hot water to the thermostat. Mostly they join that outlet to the one under the manifold to circulate the water past the active side of the thermostat, otherwise they boil pretty well staight away.

I am interested in what you are saying happens.

[russ]

I can't claim the idea...........was brian M idea...........he got the shits with allans ej so he experimented.

Can see em both with the bleedin gyro ina ditch, one wheel right up tryin to get that bleedin air out of the system. Was a long drawn out event.........lotsa cursing going on.
Then when the water was drained later on for another mod, brian said noway was he going through that pain again............cya

Yea.....forgot, brian said sumin about that water outlet / inlet........whatever, was the lowest point in the engine, so it pushed the air higher and higher up the engine as the water entered into the system.

[Aussie_Paul]

No offence meant Russ but you have this habit of going off half cocked without any real info. Have a look at your similar thread on the US forum.

This could lead people to make real mistakes based on your half info. As I said, no offence meant.

Aussie Paul. :wave:

[russ]

No probs..........shyte, if i'm wrong........Oops

am checking to be sure. [ BTW........we are talking about the filling point here, to stop the air lock probs ]

Yes Russ. It is just that when you said to take the plug off the heater hose pipe that says to me that the heater circuit is not in operation. THIS WILL FRY the ej series of engines.

I am just trying to save someone from making a mistake.

It is funny how some engines give airlock problems and others don't. The one I am running at the moment is easy. Just fill it up, and then top it up after the first flight.

I believe the car maintenance manual says to fill the system up, run the engine at 2000 revs for 5 mins, let it cool for 30 mins and then top it up and the jobs done. My radiator guy says that he has more problems replacing coolant in Sooobs than all the other makes put together.

I have found in my worshop a lot of cars that will not fill easy so i drill a 4mm hole in the thermostat plate this helps no end (some still give a bit of trouble )
Hope this helps

[russ]

Yea, that helps as well.......the holes thing......

Rob P filled his new ej today useing same system [ heater hose opening ] worked a treat.

he then decided to route that heater hose to the bottom of the radiator.

Now to that bit about cooking the ej's if the heater outlet is blanked off.........................i am near certain my ej, rusty's ej, brian m's ej are all blanked off at the pump............am checking to be sure. Standby.

[russ]

Yip..........all engines have that heater outlet blanked. No heating probs at all.

Ok.........going with your theory........that, "that" water must be in the loop. In the car it goes to the heater assy, fine...........but when the heater is turned OFF....."that" water is goin nowhere, it's been shutoff to flow around.

Sortof blows your theory.........or sumin is weird here :confused:

and that half cocked bit............be me 357 half cocked up ya left nostril :pistoles:

Ok Russ, it definately appears you are smarter than I. :yes: I may have made a fool of myself, AGAIN!!!!

Although I still stand behind my statement you are always going off half cocked.

In the car the water is not stopped from flowing when the heater is turned off. They just stop the air going through the core, not like the old days Russ. :peace:

[russ]

Hey PB...........what have you found out re this hose thing.

Some say no go...........then i know of 4....5 machines going perfectly...........blanked.

get sniffin..............

[Dewie]

All cooling systems have a water bypass, THEY MUST!!!. Other wise the water in the engine does not circulate when the thermostat is closed which will cause localised over heating in the motor on warm up.
Water by pass is either done by an internal port (rare), a small by pass hose from the water pump to the thermostat housing below the thermostat, or a heater circuit which does not have a tap.

Russ/Paul,
Air rises in fluid, it don't sink. Watch your beer, the next time you are having one. Any time you have a high point in a cooling sys, you WILL have trapped air. The smart money is always on dynamic bleeding. The rad cap should be the highest point in the whole system, and every other "high point in the system should be plumbed to just below the cap, usually into a small pot arrangement. Any time you have the coolant directed downward, you have potential for trapped air. Early 25's were very prone to head cracking because "improvements" in the casting allowed air to be trapped. It wasn't found until after the servicing at dealers when the coolant was repalced. Later models addressed the issue, but unless dynamic bleeding principles are followed, you risk overheating from trapped air in any engine.

And like Dewie said. There must be some form of bypass for the thermostat. Otherwise, the stat won't open until after everything else is well and trully cooked. Russ will probably find that his men have drilled a hole in the stat to allow warm coolant to reach the thermostat so it can open.
FWIW
Cheers

I havent had any cooling problems in my 2.2 and the reason why? well, Tim did the set up and guess what, the radiator cap is the highest part of the system.

Well said FW.
