Overheating problem...Too hot too quick!

[Interceptor'85]

I recently had my car serviced for overheating and now im finding the fans are kicking in way to late, and the engines getting too hot too quick, even after a short driving time.

any idea how I can adjust the thermos to turn on at a lower engine temp and keep her running cooler?

Cheers

what is the temp guage saying?
and when are the fans coming on?

[AUII_Forte]

My fans come on really late as well. I don't think I've ever heard them on high.

Before I flushed the cooling system and changed the thermostat the temp used to get pretty high in traffic with the AC on and the fans always stayed on low, I'm begining to wonder if there is yet another problem with the bloody thing!

[EFFalcon]

mines the same.
the 2nd fan kicks in @ 3/4 of the guage
drops it to 1/2 in no time... but i would like it to come on earlier.

[AUII_Forte]

Mine has been over 3/4 I think, but the fans have still stayed on low.

ever since i replaced some of them baby heater hoses, mine gets really cold wen idling, its brilliant!

you could do what us ea-ed guys do with thermo fans.. get one of the davies craig thermo switches (or similar) and rewire the fans up to that. that way you can adjust them to come on at whatever temperature you want.

for around 60odd? to

That would be great, to have adjustability.

She's sits between 1/2 and 3/4 and after a while of driving (say 30mins) she starts gradually creeping to the max line.

On the way home from the cruise on saturday, on the eastern freeway, I gunned it a bit up to 100kmh (not long at all) then I could see the gauge gradually get higher until she was beeping at me!

This didnt happen before the service... stupid new oak ford :

[neb]

what sensor do ef/el's use to turn on the thermo fans... maybe that sensor is stuffed?

the fans actually do make a big difference... one of my fans stuffed up on sunday so i just unplugged the wiring for it, but i unplugged the other fan as well first by accident and hooked it back up but didn't realise i had hooked it up backwards... so i only had one fan hooked up blowing air the wrong way lol. it got very hot fairly quickly, swapped the wiring around and went back down to a nice temperature.

The EF's use the one sensor, so the computer and guage are getting the same signal.
I wouldnt drive the car if its getting up to the max line, what did they do to the car to fix the overhaeting?

[Umineko]

I have a DL Ltd and it seldom rises above about 1/8th of the gauge regardless of road conditions or speed, Last week to my horror it actually crept up to 1/4 while I was sitting in the usual crappy Melbourne peak hour standstill. after reading the posts here I don't feel so bad. after spending last weekend changing front bearings/ pads and rotors as well as the vacuum booster I wasn't really looking forward to a weekend of stripping down the cooling system. I was led to believe that the Fairlane/Ltd was more prone to cooling issues than the Falcon owing to the increased weight and more restricted cooling air flow from the front, any truth to this ?

the V8's are better then the 6's when it comes to heat

[neb]

anything over 1/2 way on the guage seems a bit too high to me? mine sits at around 1/4 in normal, doesn't really move.

Here's what i had done...

- Replaced Head gasket
- Au housing water outlet
- Ea thermostat seal
- Ef kit engine gasket upper
- Au cylinder head bolts
- V pin tubular guide
- Ea O ring timing chain
- EL thermostat housing

its not going to the max line all the time, just after lengthy trips. they just turn on too late. didnt happen before this recent fix up.

Geez I hate new oak ford...they tried to steal my tickford snorkel!!! came back to me with a stock snorkel, and they "couldn't find it" when I blasted them about it.

Did the temp stay constant before the head got done?
The radiator could be a little blocked, and by the time the fans kick in they just cant bring the temperature down?

the heat is still there its just that its not in the engine, its trapped in the bay making all the wiring looms hard and brittle, melting your plastic alarm sirens.

Yep ;) You certainly notice when you pop the bonnet on my car after a drive.

Yeah the temp was constant, ran very nicely.

[megsy]

mines a eb2 whith all standard and when i bought it i had to flush the cooling system (more than once) and fix the pump before i could get the system to stay cool, now it doesnt even rise into the normal part, even if i gun it. also it still has the standard fan.

I forgot to mention that two distinct coolant puddles show up on the ground directly under the thermo fans.

I'm guessing some hoses have detatched or got holes in them or something.

What could this mean?

Could mean that you sort of answered your own question? :S

[Damo]

So why did you actually get the head gasket and all this work done ? You state in your first post it was due to overheating issues, yet later on you say temp was constant 'ran very nicely'. I'm a bit confused. Also why did they put EA parts in your car. lol:S

With the coolant puddle it's probably you bottom raiater hose, which goes to the coolant overflow bottle. Take it back to wherever you got the work done and tell them whats wrong. Hopefully they'll fix it for ya.

[mik]

the middle of the gauge is generally about 185 farenheight(85 cel) i think on a 20 celcius day about half way or just under is about normal i think maybe a tad more with air con running if it got to 3/4 temp i would think about getting it checked out sooner than later.

Ok before i got work done it ran fine, but the thermo housing had a dodgy patch up i didnt know about...I ran the car hard and blew than dodgy patchup off, to reveal a hole. It OVERHEATED. Took it to get fixed and turns out more needed work.

Now after the "fix" about 30mins driving she heats up too much, and what ive only just found to be the hose problem.

They've put EA bits in my car because they're dodgy f**kwits and Im so sick of complaining to new oak ford about these problems. Hopefully the morons down at new oak ford will fix things this time. I know they've been sneaky with a few people, like my good mate K-man.

Hope that clears the story up for ya Damo ;)

BTW

Is an EA thermostat seal and an EA timing chain O ring suited for an EF?

Or is this something else I have to blast them about??? :

I had the same problem with mine it seams when your head gasket gose and ti ti replaced you also need to check your radiator as it will be blocked ( as mine was 40% blocked but was not leaking) i think that would be your problem....



o i own a 98EL futura saphire

fans wont cool your car at 100km/h.

fans are there to cool your car when stationary.

if its overheating with wind blowing through the radiator at 100km/h, the radiator is blocked!
