evening all,
i put some antifreeze in my fd two days ago, and the water temp went up to 98c never done it befor seems to be since i put the antifreeze in, it usualy stays at 85c - 86c, just a bit woried to be fair, only had the car 3 weeks,is 98c a normal thing? cheers ian.
hi ian, that does seem a bit strange, mine stays at 85-86, what coolant did u use and did u mix with distilled water, remember they aint normal cars lol nick.
hi nick, i put 1/3 of a 1 litre bottle of carplan blue star antifreeze in, no water, i didnt realise you have to put distilled water in,also i didnt mix it oops is that bad? cheers for the reply ian.
puting distilled water in does nothing ;) the reason for this is, as soon as it goes through the iron plates it becomes the same as tap water..... so save the cost & just put tap water in ;)
Could be a slight air lock..... try taking the water pipe off the back of the inlet manifold & see if it needs bleeding, & for the quantity you have put in you don\'t need to worry about the mix as there will be plenty of water in the system to dilute it.

new to rotarys myself jono, was told to mix by guy i bought it off, cheers tho ;)
how long u had the rex for dj?
oh i see cheers jono, il have a look afta , iv had the car 3 weeks nick, so mutch to learn bout these lol, how long u had yours?
hi ian, took the plunge 5 weeks ago and didnt really do my homework as i shud av, bought with my heart definately not my head as she monsters petrol, fortunately i\'ve bought a good 1 with a recent full rebuild with large streetport with sensible and safe mods to go with it, good job its my weekend car, must be a nightmare as a daily, what spec u got, cheers.
Running water temp at 98c is way high i believe for water seals...
if i ever reach 100 i stop immediatleyto recover the temps.
You prob have an air lock of some form if this only started happening when playing with coolant.
98 is fine in some conditions. What were you doing at the time? Sitting in traffic? Caning it? On track etc?
You\'d be surprised the temps that you will reach. I\'ve frequently hit over than and not driven away with my car in bits ;)
Think the terminal death temp is something like 125c..... when you turn off the engine after a run..... go back & flick on the ignition so the temp reads & you will be looking at a rather scairy 110c or something similar!! It\'s suprising how hot these things can get without dieing!!

Remember kids, it\'s not boiling at 100 degrees C... ;)
On my stock Rex with stock rad I never see more than 90 even in traffic
its a 94 type r fd3s in white nick,19inch crome rims bodykit ect it had a difrent engine put in by me mate, runin big single turbo however oil seals seem to be goin ,i knew about this wen i bought it payed £3500, get crimbo out the way and il sort that out,i drive it every day lucky i only live 3 miles from work lol,as for the coolant it does it if iv been driveing ova 25 mins, if im sat in trafic it goes up then if steady driveing will come down a cupple of degrees, il bleed the system tomrow and change the water is there anythin i should know? still a newbee to rotarys,il have a look what it says cupple of mins after shut off more paranoia lol,
had a look at it today and found that the fans wasnt workin wen i turned the ignition on,they are constantly on in mine for some reason,also the car head unit sometimes doesnt come on, wile i was haveing a look earlier the alarm went off because i forgot to put the car in valet mode, wen i locked the car then opened it again the fans were workin and the stereo came on , are they linked in some way or what could it be im baffled to be fair, help needed im not to good at electrics :-( ian
Also remember that coolant will not cool as effectively as water.
The order of cooling effectiveness is;
1. Pure coolant
2. Coolant + Water
3. Water (but it will freeze and oxidise)
4. Water and Water Wetter (or similar)
So dumping a chunk of pure coolant in, not as the right mix, will increase your temp slightly although I\'d say not as much as you\'ve seen.

Im not sure why it doesnt increase the effective cooling....
But what it does do is increase the boiling point. And unlike the freezing point, where you need to go to a 70:30 mix to achieve maximum protection against freezing....for boiling it is 100:0
As ever the answer lies in science.
You are incorrect in your assertion of a 100:0 mix however.
As concentrations of coolant/antifreeze or more particularly ethylene glycol rise, so the freezing point lowers, and the boiling point rises. Pressuring the system (eg via a 15psi pressure cap) will raise the boiling point a further 25o or so.

My stock one got up to 100oC if I was sitting in traffic in summer but the fans kicked it down to around 90 again.
After getting the PFC it never gets past 90 and averaged 82-83.
Now got the Feed FMIC and rad fitted and it\'s now around 78.
all sorted now guys, the car has ben wired so that the fans are on all the time and its been conected through the power that goes to the stereo,the wirein wasnt very good realy, so riped all the old wires out and put new ones in, not conecting them to the stereo though lol, all working fine and staying at 85c now,im still going to do a coolant change just for piece of mind, next job new turbo ,:Hammerouch, thanx for the help:cheers
You want to go careful that you have the correct gauge of wire here as the fans do draw quite a large current!
that was the problem befor, someone put a fuse in the circut that wasnt up to the job melted everywhere, iv put twice the thickness of wire in and a rockford fosgate fusebox in seems to be fine now what u think atomic?
Without seeing the wire, it is difficult to comment.....lol
25 Amp wire is approx 2.5mm thick. Now according to the book, the standard fans draw 13.6 Amps at max....now what it doesn\'t state is that each or both....I would assume that it is each as our fans draw close to 30Amps at max draw. The largest draw will be at the beginning...and then it will calm down a little....so if your wire is 2.5mm thick or thicker.....then jobs a good-un
That said, this doesn\'t include the stereo...what current does that draw??
Personally I would have it on different spurs, and with a fuse in line
i think jobs a gud1 in that cace pal, i used some wire that i got from work its about 3mm thick realy heavy duty and well insulated,the fuse i used is off my old rockford setup looks nice and tidy now, carnt see any other bits that have been changed fingers crossed lol,
as for the stereo that is wired up on its original wires so nothing changed there:Thumbs-up
i, its all top fun ian, dont get me wrong there a top car and fast but you carnt help but worry bout the darn things, ther again i think all powerfull cars are abit the same specially when you start pushin up the power, fingers crossed youll have no major issues, cachya nick.
