Hi

I just got my car fitted with a brand new EF radiator and EF twin thermo fans. but i want to drain the water out of the radiator and refill with coolant, but when i went under the car the drain plug wasn't in the same place as the old EA radiator, Where has it gone!!!! Grrr.Other than that I am very pleased with this modifacation i can really notice the extra power gained by taking the old clutch fan and so quiet, all you can hear now is the engine revs. If anyone can help it would be very much appreiciated.

thanks

Peter

Hey

The drain plug is under the radiator on the drivers side. I find it easier to take the thermos out and take the bottom hose off the radiator.

Cheers

Hi

Thanks for the quick reply, I checked again the hole is on the drivers side but there was no drain plug Hmmmmm .I was going to do it that way, but I wanted to make sure that i got all the water out of the system, as i am using a premixed coolant (Castrol Radi-Cool). Would I get all the water out this way?

hey just wondering did you do the conversion your self or did you pay someone to do it for you, if some one else done it can i ask how much you paid for the conversion and how long it took???

Well I did it by taking the bottom radiator hose off, not sure if i got all the water out, because when I refilled it with coolant I could only put in 10 to 11 litres, anyway we will see how it goes.

EA_GHIA_2NV: Yeah I got my mechcanic to install it for me
Parts cost :
EF radiator Brand new = $296.00,I was quoted by Ford for an EA radiator $487.00
EF Twin Thermo Fans Second hand = $160 .00
New Bottom Radiator hose $23.15
Auto electrician to hook it all up = $120.00
Labour = $180.00
All up $779.15, there other things that weren't included like coolant which I added myself and a new header tank which just finished installing

In reguards to time (this is going to be a long story, if you don't want to read this skip this part) it all started back in early november last year when i went my mechanic for a service i told him that i wasn't happy with radiator as it was over heating alot, there were no leaks or cracked pipes, so we narrowed it down to either the radiator, faluty thermostat or the water pump impellors being rusted out. so he tells me that he converted this ED to the EF radiator and thermo fan set up and best thing for the car he quoted about $400 - $600 to do the job, i told him i was a bit tight for cash at the moment so i told to book it in for about 3 weeks time he said no proms it give me a chance to order the parts in. Now its about the second week of december i bring the car in, do you think he got the parts in, take a guess, anyway he final get the part in 18th or 19th so he says no worries i ll have it ready one hundred percent before christmas. i give him a ring on the monday before christmas to see how hes going with everything, he says that the electrician took off on holidays on friday and he didn't tell him so he didn't change the radiator over. Not happy jan :(any way he said he flush the radiator out and shouldn't give me to much of a problem. Take off on boxing day out to Coonabarabran which is 200km west of Tammworth it should be a 6 hour trip which turned out to be 16 hours because of over heating, I noticed water hissing out from the bottom pipe under the header tank, it was lossing about 4 litres of water every 45mins of driving, i though this could be the answer to all my problem so i go to the ford in town and they said there was a small crack in the bottom of the header tank water was escaping because of the pressure (now i m getting typing cramp) so i told them install a new they had courier one in from Dubbo, all up it took 2 days (because it was between christmas and new years) and $245 (out of my buget for going down to the nats). Then i starting thinking if there was too much pressure build up a pipe or something else could blow up, so made the decision to put the old header tank back on and take the thermostat out at least that way i knew i could make it back to sydney. I drove all night it still took 11 hours ( I don't recomend driving at night it is very dangerous. jan 5 take car back to the mechanic tell him the story of what happen, he said ill get fix for you. jan 17 pick the car up. I don't want to sound like i am knocking my mechanic, he is really very good and i would recomend him to anyone, it just he is a one man operation and i reckon he does a really good job of it. I just reinstalled the new and very expensive header tank and refilled with coolant

If you made it this far i recon if source and have all the parts and tool that you need, if you have a bit knowledge of taking cars apart and you know a reliable auto electrican you should be able to knock this conversion over in a week end, it just takes time fine tuning the thermo switch to it optimal performance which is the tricky bit.


geezz it 11 o clock
hope that helps

I did it my self with the help of my bro who is an electritian. It was a bloody neat job you couldent even see the wiring ar switch


A POINT I AM GOING TO STRESS, is that instead of using a blade fuse on the thermos use a self resetting switch instead, and hook a piezo buzzer up inside the car so you know if it does trip . I had the fuse blow once and i didnt notice until it was too late. the excess pressure blew my overflow tank apart. head gasket was fine though luckily



Overall a very good cheap conversion, probably only cost me $ 200 all up... and get the EL thermos if your going to do it, much easier

Do a search on the Forums.
Theres a guy here who makes a wiring loom specifically for this purpose.
I have changed mine to a twin thermo jobbie & havent looked back since..

NZ said:
How many people run the standard thermostat when they put thermo's on EA- ED?
Nope not I
As i recall the last to use drain plugs were the ED's as a mate with an EF took his radiator out to get it fixed & it didnt have a drain on it at all.

It was interesting, I was talking with a friend of mine who was heavily involved in the development of EA - AU falcons about a set of fans I have recenly bought to put in my car. His first words were 'We'll have to do some ducting work so your car won't be prone to overheat'. Natuarally I was slightly confused.

Basically they did a lot of testing on EA - ED with the use of thermo fans and what they concluded was that these cars were prone to overheat with twin thermo fans over the clutch fan setup. I couldnt really understand it at first untill he explained some of the problems.

Basically the front bar of the EA - ED isnt really a good design for forcing air into the cooing system. Put an EA and an EF side by side and look at the profile of the bars and its quite evident where the air flow at the front of the cars will be. Because the EA - ED bar goes under itself the air flow tends to go under or over.

At highway speeds the difference between the fans beomes one of the main reasons why they went with the clutch fan setup. Your typical clutch fan spins quite substantially and draws a fair bit of air through the cooling system when your belting along. Enough to keep things under control. Plant it, the car heats up and eventually the clutch fan locks up and spins a hell of a lot faster. No problems there.

With a couple of thermo fans they will be sitting idle and actually creating a resistance in the system. They do spin from the airflow that will be there, but largely very little happened when they put these cars in the wind tunnels. What effectivly hapened was that the cars had already begun to over heat before things kicked into action.

With the front of the EF bumper air is naturally going to be forced therough the cooling system as there is substansial opening and also the front profile has quite a sharp edge design. There is also some ducting in the front of the EF to pull tha air flow up to the top end of the radiator as well.

I've noticed some people have mentioned their cars have run hotter at highway speeds with thermo fans on and their fix was to run a colder thermostat. It seems like its a patch up fix as in effect whats really going to happen is theres going to be a higher flow of water to keep the engine at the right operating temp. Setting the thermos fans to start at a lower tempreture sort of defeats the purpose of having them. The fans should not have to turn on during normal driving at highway speed. If they are cycling in and out at highway speeds then thats evidence that if they were set to the appropriate tempreture then overheating would occur.

They aren't so much of a problem on the V8's as the guard under the car extends further back and somehow helps create a vacuum - I forget the reason why it des this now, and with the added space behind the radiator from having the shorter motordoes a lot to help as well.

Don't get me wrong I'm all for thermo fans but after doing a bit of research its something I'd be a bit careful of.

Well NZ my car runs cooler at 110 even when I accelerate then around town, thermos have never come on at 110, in fact if they are on it cools enough for them to turn off and this is even on very hot days.

I have changed my front bar if you have a look at my pics (http://www.fordgallery.com/showgall...hat=allfields&name=dellboy999&when=&whenterm=) and maybe that is helping the problem, also I have don't have that bit of plastic that is supposed to hang down or whatever under the car, so maybe thats a way to make it work better I dont know.

mmmmm Interesting points about the front bar between ed-ef onwards, I have not noticed on mine any sort of heating problem however since it is still pretty new im watching it like a hawk so some perculieralities may pop up, if they do I will inform everybody.
