EA running a bit hot

I have a turboed EA falcon now it runs at a temp of about 85 to 90 degrees when driving but when she stops at traffic lights and its warm out side it creaps up past the 115 degree point it would probable keep going if the lights did not turn green

I thought it might have been the airconditioner radiator as it was bashed almost flat on the back (didnt work anyway pipe was cracked before i got it) there is also an intercooler aswell but I wouldnt think this would cause the prob

Any ideas?

Re: EA running a bit hot

Howdy Skara. Have you checked the usual customers such as:

1. Clutch fan
2. Thermostat
3. Leaves and crud between condensor and radiator.

Also, if the fins on the back of your condensor (air conditioner radiator) are squashed flat, then maybe it is impeding air flow too much when you are stationary.

Another thought may be to just take it out alltogether and dissconnect the airconditioning system. hehehe...less weight, less power being sucked, can only be good The only thing would be if you had an auto, in which case you would have to install a tranny cooler.

Re: EA running a bit hot

I have already removed the condensor as it was bashed in at the back the thermostate is new less then 5000KM (spos it wont hurt to replace) and what do you htink about a flex fan instead of the clutch fans or would I be better leaving it as is. I also have the piping for a oil cooler I might reconect it when I can get a radiator for it.

Hey bro sounds like your having the same prob as me, remove the clutch fan and put in some el thermos, run through a thermo switch, adjust thermo switch to correct temp so fans switch on. if that fails, get the radiator flushed.

Re: EA running a bit hot

I have a few good clutch fans if you wanted to try swapping one as a cheap option...

Re: EA running a bit hot

if you're confident with this sort of thing take the radiator out. the side tanks are plastic, and are held on with two clips. get them off and you'll be looking down the radiator lines. you'll probably find the radiator side tanks are filled with a sandy type substance, this is actually coolant that has broken down. you can have a crack at rodding it with the dipstick (its the perfect size!), but be very careful as its easy to poke a hole. just rod the ones that are slightly blocked and leave the really bad ones.

Re: EA running a bit hot

Actually on a lot of the EAs my understanding is it's casting sand, certainly looks like it to me This I believe as most of the blocks on the 3.9s seem to have decks which are not straight - from factory!

Re: EA running a bit hot

i think the straightness of the deck might be more to do with 'seasoning' of the block, more than an actual machining issue - repeated heating and cooling of the block causes all the little stresses that are cast into the block when it is cast makes the block move and deform slightly - this is actually a good thing, it kind of 'relaxes' the block, so when you give it a slight machine and a rebuild to turbo the crap out of it all your carefully measured clearances are more accurate.

there is actually a machine that does this 'seasoning' i think it uses sound waves or vibrations or something.
