car still running with temp gauge at 'N'.still no mayo in oil,but fan only cuts in when temp right up.took off heater pipes yesterday& flushed loads of s**t out but still no joy!changed thermostat,& flushed rad already.changed gauge sender twice.does anybody know if ford used different senders for different 1800 zetecs as i dont have faith in my local dealer(ask for parts for fiesta rs1800 they say "rs turbo?"

fools. i need to sort asap as idont want to f**k the head if its not gauge.

i dont really get what you wrote but from what you say it seem normal?? :-?

by **Sunil_FiestaRS_16V** on Mon Apr 14, 2003 9:04 am

the fan on my rs cuts in just above the "o" i think. if ur worried about overheating take ur themostat out all together and run ur fan on constant then i doubt it will over heat.

by **unknown_user** on Mon Apr 14, 2003 11:36 am

they all do it mate Si and rs1800 and 2L fiestas well mine did! if thats any help i was worried about it at one time! fan only come on in traffic normally!

by **chumkila** on Mon Apr 14, 2003 11:37 am

yea sounds about right.

by **unknown_user** on Mon Apr 14, 2003 11:41 am

just wait for steam then get worried?

by **chumkila** on Mon Apr 14, 2003 12:29 pm

by **and.RS1800** on Mon Apr 14, 2003 5:06 pm

yes but the needle sits up this high all the time.fan cuts in fine but gauge doesnt go down again.didnt do this before sender packed in.needle used to sit on top of 'M'!

by **chumkila** on Mon Apr 14, 2003 5:09 pm

ahh now i understand.

by **and.RS1800** on Mon Apr 14, 2003 5:18 pm

thats why i wondered if they used more than one type of sender for zetecs because the parts/service staff at my local dealers seem so vague about any parts i buy.

by **chumkila** on Mon Apr 14, 2003 5:24 pm

there are lots pf peeps on here with microcat CD's, i'm sure they could clear this question up.... just gota wait til they see this post.

by **and.RS1800** on Mon Apr 14, 2003 5:34 pm

also car didnt seem to run quite as well after cam belt change.didnt seem to have same kick up the arse at 3500 -4500revs.if yer man didnt get cam timing spot on could this have caused over heating & buggerd me head gasket?

by **chumkila** on Mon Apr 14, 2003 5:35 pm

yea cam timing is VERY important and must be spot on.

by **FezzR** on Mon Apr 14, 2003 5:42 pm

doesnt the fan and the guage have different sender unit?

by **and.RS1800** on Mon Apr 14, 2003 5:44 pm

baxtered mobile mechanic.done it on my drive in the dark!couldnt get ford main dealer to do it as i dont get home fromwork in time to sort it and girlfriend wont drive it!

by **chumkila** on Mon Apr 14, 2003 5:45 pm

mate dont mean to sound bad but no bloomin MOBILE-anything is ever gona touch my car! :oooh:

by **and.RS1800** on Mon Apr 14, 2003 5:52 pm

yes fan sender is in rad.but what i was hoping it was just wrong temp gauge sender ,which would mean every thing else is fine.if not sender is it bad airlock?havetried every thing to bleed out any air by loosening all the hoses etc.only 4.5 -5 litres of coolant would go back in.haynes say 7.is this due to coolant which hasnt drained from block?

by **and.RS1800** on Mon Apr 14, 2003 9:55 pm

mobile man wasnt some chancer with a van & some tools,he was proper vehicle technician.franchiesed to green flag

.didnt really hav much choice as i say girlfriend wouldnt drop car off any where & iddont usually get home from work till after six.anyway i know people whove worked for main daelers like godfrey davis & perrys &they have not carried out certain service jobs which the customer is being charged for!!i had bad experiance with my old jag,where it whent to specialists for major service & i needed raer suspension rebuild,so did it my self,half the things they said needed doing were fine

they never even greased it.then had the cheeck to argue & ask if i knew what i was doing!anyone else had bad experiances of specialists/tuners?

cam timing has a very big effect on running temps mate

by **Mav Singh** on Tue Apr 15, 2003 12:29 am

how will i be able to keep the fan running constantly on my Si?

by **Sunil_FiestaRS_16V** on Tue Apr 15, 2003 9:32 am

Mav Singh :how will i be able to keep the fan running constantly on my Si?

unplug the fan plug and bridge the two connecions with a piece of wire

by **bcracknell** on Tue Apr 15, 2003 10:33 am

what is the optimum runnins temperature for an engine then? I know the thermostat doesn;t open until 88degrees so presumably about 90 degrees on a run would be ok?

what about oil temps?

by **Mav Singh** on Tue Apr 15, 2003 12:56 pm

where is the fan plug located?

by **Mav Singh** on Tue Apr 15, 2003 5:32 pm

also if this plug thing is bridged will the fan stay on even when the car is switched off?

by **Charliep** on Tue Apr 15, 2003 5:52 pm

nope, bridged my FRST cos after the T3 conversion it allways got hot under the bonnet, now it never climes above the r on the dial. found that after the letter r it never ran well so was the best thing for it

by **and.RS1800** on Tue Apr 15, 2003 10:00 pm

if it is cam timing & head been buggered how would i stand regarding recompense from mr green flag?also,how much to to get it checked? methinks about nearly the same as labour to do cam belt in first place?if it was out wouldnt it run very rough and not rev very well?she'll still redline through the gears.

by **sexy-aRSe** on Wed Apr 16, 2003 11:05 am

Mine always runs up to N then fan kicks in i was on a paranoya when i got it that i was gonna cook it!

So i got a switch put in my car so i flick my fan on myself

by **Mav Singh** on Wed Apr 16, 2003 12:28 pm

yea my dumb si plays the scary game with me all the time the temp needle goes up to the N and then the fan kicks in untill the needle drops to the O. was wondering if someone could post me a guide on how to fiddle around with the fan to either make it stay on all the time or to make the fan kick in earlier like when the temp gets to the O insted of the N?

ur fan has a switch in the rad which switched to on at a certain temp u can either bi pass this (put a switch onit or bridge the connections so its on all the time) or u can get a switch which "opens" at an earlier temp. u can also change ur thermostat for one that kicks in at a lower temp.

just a note though zetec engines can run really hot so it is usuall for it to kick in above the "O" and just below the "N"

by **and.RS1800** on Wed Apr 16, 2003 10:59 pm

yeah,but mine warms up then needle climbs steadily up to the 'N' & stays there,fan on or not!!

by **Mav Singh** on Tue Jun 28, 2016 8:43 am

is it possible to upgrade the rad in these cars? would like cooler running on my si. if its nailed in 3rd gear the temp does climb up but doesnt overheat. scary though.

or would just getting a new rad to replace my original 21 year old one make any difference?

by **Mav Singh** on Fri Jul 22, 2016 3:31 pm

got a new rad and makes no difference to how the temperature responds, got a lower opening fan switch which does kick the fan in a little bit sooner so that will have to do.
