Car Forum / Ford / Ford Falcon / March 2004Overheating EB???
Hi, I have a question about why does my EB Falcon like to overheat these days... I have had the head-gasket redone, changed the thermostat and changed the radiator cap. When we get a warm day (mid to high 30's) my temperature gauge will reach right up into the red area. When it is an average temp day (mid 20's) the temperature gauges fluctuates up and down. i.e.. It will go to the top of normal and then suddenly just drop down to the lower part of normal. When it does finally overheat, I remove the radiator cap (with a thick towel over it) and it what coolant is left will violently spurt out. I usually refill it with the cheap $5 coolant, however this time I used Tectaloy 90 Plus at $18 per 5 litres, and it took nearly 10 litres.( http://users.tpg.com.au/brecon/radiatorcoolant.pdf 6.86Mb) I raised the vehicle on a angle when filling, as I understand that this the appropriate way, and even with this more expensive coolant I am still noticing the gauge heading toward the top. More so when stationary or moving slowly. Any ideas??? I am not ready to get a new Falcon yet, as I am in full-time study... : ) Whoops... The URL for the label on the radiator coolant is actually http://users.tpg.com.au/brecon/radiatorcoolantAU.pdf > Hi, I have a question about why does my EB Falcon like to overheat these > days...

Thats sounds like a typical E series Falcon problem, what thermo did you put in? It needs to be a dual acting job and have the jiggle pin. A dual acting thermo has then normal main housing + a disk protruding from the bottom which closes off the bypass pipe at the bottom of the thermo housing when operating temp is reached. If it doesn't have a jiggle pin, you can drill a small hole in the thermo flange, the idea is to allow a small amount of water to slip through. If this is the problem, the symptoms are start up from cold, temp goes into the normal zone then drops, goes back into normal zone (could even go into red) then drops again and so on. As other have mentioned, you may also have other problems such as blocked radiator or stuffed clutch fan.
