Coolant burping procedure question

[not a gt]

Hey guys, need some clarification: ok, top off reservoir and cap, open crossover, fill, start car, thermostat opens shut off and fill and install plug. 1 hour later, remove plug, top off, leave plug out, 3-5 hours later, top off, plug and drive. Next day remove plug and top off. Now my question: Says if you have to add more than a couple ounces, do another heat cycle. Does this mean plug and drive again or when you pull plug to add, do that part again where you run the car till thermostat opens with funnel in for air to escape? Thanks

You do NOT need to drive it to heat cycle it. Just let it idle, I'd let it go 10-15 degrees past opening temp to make sure it opens completely and has some time to push fluid. The idea with the funnel is to keep coolant in there so it can fill and burp at the same time while it's running

Larry you need by my uview coolant tester
Will never have to burp coolant system again

Oh ok, so do the cycle, install plug snug, after hour, remove top off. Should I leave the plug out for the 3-5 hours like sheet says when cool or top off and put plug in. Then next day just put funnel in and do again??? I just did it and only went to 172, guess will go higher, as well can see if fan comes on..that was another issue, tab was broken off connector on top fan plug so I spliced in a new one, think it was braking connection, around town yesterday hit 222, then dropped, here's to hoping

[ASH302]

that is a good find. man I'm looking forward to hearing you say everything is good.
BUT..... there is always something

an intermittent fan would sure explain some things...

maybe Im not following how youre burping it...

if you have a funnel that will fit in the fill port and you can leave the funnel with a bunch of coolant in it while the car runs then theres no need to shut it down. Once the thermostat opens it should push air out of the funnel and then coolant will drop in, if the funnel goes dry add some more to it.

I didnt have a funnel that worked that well so I would top off from the crossover tube (do NOT open the over flow res from here out!), put the plug back in the crossover tube, run car to operating temp (210 or so for me with stock thermostat). Id shut it down and let it cool for an hour or twp then open the plug and top off if needed. If it needs fluid repeat burping process. In the 2 motor swaps I did I think it took each car 3-4 burps and they were done

I am using that Reische burp procedure..what I did I filled resrvoir and capped, filled crossover till about inch in funnel, started the car and kept level even in funnel, once T opens, fluid rose in funnel with big air bubbles, when I hit 172, I shut off, removed funnel, topped off at xover, put plug in snug, wait an hour, uncap xover, refill.. now the sketchy part, THEY say 3-5 hours later, install plug after topping off again if needed and drive the car. I have a good tight funnel, so what I was going to do was top off after cool down, install plug, then do the crank up and funnel fill again tomorrow.

Oh, so with your method you don't see air bubbles coming out, just letting them pass thru the system?? How does the air actually then get out of the system if just running with plug in??

What happens is when thermostat opens, yea level drops in the funnel, but as it heats up and expands starts coming back out funnel, you have to shut it down for level to drop back into crossover or it will just boil over out the funnel..man seems so simple reading it, but little bit more to it.

[DSG2003Mach1]

when running it up to temp with the plug in place the water in the cross over will drop down into the system and the air will collect in the crossover. Just open the plug and pour in more coolant. Worked for me anyway

[not a gt]

Ok cool, I think I got it figured out. I ran it with the funnel up to 188 and started to rise with small tiny air bubbles, shut it off and it dropped..topped off and put in plug. Now...Kurgan said he has my low speed fan come on at 175 and hi speed at 182. When my temp on Aeroforce hit 188, fan came on and I think at hi speed. At 179 it cut off. I read somewhere there is a seperate fuse some where on drivers side for lo speed fan, supposedly sitting all by itself, is this true??? I think though that is the problem...no low speed. Also, when I turn a/c on. fan doesn't come on immediately, sat there and after about 30 seconds fan came on, not sure if that is normal, thought fan came on as soon as you turned on A/C. Not sure why all this is going on now, NEVER had any fan issues prior to this motor swap.


I read this


The device on the fan shroud contains a ballast resistor and fusible link. The link will open if the resistor overheats, and resets when it cools, however if either component burns out the fan will not run in low speed. This component is not shown on the wiring diagram as it is considered part of the fan assembly.

I have one of these in a fan I have that a blade broke off...should I try popping that in??

If you look in this wiring diagram, it shows a 30 Amp auxilary fuse for the Low speed, any idea where it is at (BTW this thread post is from owner of 04 Mach).

http://www.paladinmicro.com/document...ngFan4.62V.pdf

You can look at the top, the battery junction box has the 50 A fuse, this 30 A one is located in an auxilary fuse box for the LOW speed...any ideas where this is??

[not a gt]

Ok, I found out the 30 A fuse is in a box on the passenger side forward of the strut tower, confirmed it is for low speed only, going out to barn to confirm.

Found it, it was in that big box hooked to the fender in front of strut, wonder if I may have to go to Ford for this



Using my ninja skills and cross referencing, the Ford Part # is F6HT-14526-LA
At littlefuse it is the MXB series

http://www.littelfuse.com/~/media/au..._breakers2.pdf

[not a gt]

Well, after 2 dealers found the fuse, look how ragged package is and notice the date, guess they don't go bad often



STILL no Low fan, I called Mr Kurgan about how the one speed I do have is 188 on, 179 off with a 170 thermostat, car getting hot..stays at around 188-190 and I did one 3,4,5 pull and temp went to 212 !!! I wonder if that airdam extension I put on needs to come off???



I figured this would HELP get more airflow, could it be making it worse?? Temp here was 70, I have a well flushed, well burped cooling system with a 50/50 coolant mix, bottle Lucas Super coolant..why so hot?? Does the Miezere Electric water pump need to come off?? Seems the faster I go the higher the coolant temp is ..212 ?!? What makes it worse is I am new to the Eaton world so I don't know what IS normal?????

[not a gt]

Next up gonna make sure the $60 T stat didn't get ruined from all the oil since the upper hose is soft, hard, soft, very inconsistent. Already have 50/50 mix so if I pull T stat gonna add just water and Redline. I am so tired of this I have never had any coolant issues with the car. Anyone running just high fan speed set lower and hell with low speed??

[DSG2003Mach1]

after hit 212 on that pull how fast did it come back down? 212 isnt that high. The stock fan turn on temps are 208 and 218 or something like that

while we all want to keep the cars cooler I wouldnt consider it an actual problem if you can do a 3 gear pull and thats all it got to.

i dont have any input on increasing the size of that lower air ****. I believe the ones I saw on modular fords also went further out to the sides. The other thing you can do is try to **** up the right in front of the radiator better to help force the air through the radiator. Thats also why the terminators have those vents in the hood, to help pull air through the cooling systems

you may want to go on modular fords and svtp and do some searches in the terminator sections on cooling threads and such.

[not a gt]

The issue is the sweet coolant smell I get after hitting 212 (and the fact it is a 170 T stat) and the fact temp will be 188 and the upper hose will be soft, also this morning I pull xover plug...great, right at the top, nice and green. I run car, come home, let it cool, pull plug, no coolant, stuck funnel back in and went to burp again, got some air bubbles, but now water starts rising in funnel where I have to get turkey baster out, just doesn't do the same thing each time.I shut off at 181, level dropped, filled and when I filled it was clear water at top of crossover, no green coolant(this morning it was pure green), plus though crossover will be empty, coolant reservoir ready to overflow. I just ordered another 170 T stat, I got a feeling either defective or all the oil that went thru it didn't do it any favors. Why would coolant keep going straight to reservoir? Really weird what is going on, will keep at it, should be enough coolant that when I pull T stat housing, will fill with water and some more Lucas super coolant...we have a good enough temp should be ok with all 50/50 mix in block and elsewhere, seems like I lose about gallon when I drain out housing will save some from reservoir, tired of buying new coolant to run for 10 miles.

[ASH302]

have you checked to see if any of the other 03/04 Cobra's are having this problem?

It must be a flow issue and leaning towards T stat. At 188 degrees, top and bottom radiator hoses soft (like I can squeeze together upper hose soft). I pulled crossover plug and with electric water pump I could see good flow thru the crossover with key on. I can't believe there is THAT much air to impede flow that much. Kurgan sent another tune with fan change..no low speed just high, on at 179-180, off at 172. New T stat shipped today. Also got in the Billet crossover plug, thanks for link ASH, nice piece and I already painted it

Off topic a bit, but the billet crossover plug does the provision for the temp sensor need to be plugged if you won't be using it?

Yes you would need to plug it if not using it

[not a gt]

Update: Ok, verified coolant flow is out crossover to radiator. I left reservoir closed and took out crossover plug, with the car off, key on, and water pump running, flow was decent, but about every 15 seconds would suddenly overflow out plug. I noticed a very slight hissing noise at expansion tank, so I first put crossover plug back in, then I wrapped the crap out of threads (aluminum tank) with teflon tape, and put on a new cap. I then removed the thin overflow tube and put a good clamp on it. I then opened reservoir cap and it overflowed, as well as electric water pump was spinning, it would overflow out the reservoir. I turn the key off and fluid level in crossover drops back to normal. I still have small bubbles coming up out of crossover, so for peace of mind, gonna change T stat, make sure all hose clamps tight, then reburp and say hell with it and go with the flow lol.

That is the plug in it, it came with one, I installed it with some red loc-tite.

Thanks, I was looking to get one of these, as I'm due for a coolant change, and doubt the original will survive being removed again.

This is the reason I bought this plug was to run my temp sensor from it to my gauge. I was researching and researching where guys were mounting their sending unit sensor and when I came across this, I was sold. Also I has the nice spot for tightening down and taking off, where you do not have to worry like the stock one.

im going to have to do this when I install the sending unit in it.
