right lads tryed geting my car started and worked left it running for a bit 15mins ish and it went rite up to half way, header tank was boiling, steam cumming from the header tank cap and the water pipes from the rad was hot !!!

so turned it off not wanting to do more damage and i could hear bubbling cumming from around the rad and when i could feel the rad top pipe leading to the theromstat it was bubbling still seems to have air in it would this be right ???

also my fan didnt kick in should it have kicked in be4 and would the fan not cummin in before half way effect the water that much it would boil ??

 

sounds like the water aint circulating around your engine

 

how could i sort that ??

what could i check ??? any blocking points ?

 

The fan should cut in just after half way.
to bleed the system i leave the cap off, and take the small hose ontop of the thermoustat housing off till water spurts out.

Does your thermoustat open?
is your fan switch working?
bridge the fan with a small piece of wire between the 2 connectors on the plug (fan side) when the temp guage gets to around half way and see if it cools it down. that's if the fan doesnt come on.
is the header tank camp making a sufficient seal, as the system will not cool if their is no pressure.

Is their anti freeze in the system? i think a 60/40 mix of anti freeze is right.
is your rad hot all over, bottom/top? might need a flush? did your old headgasket go or did you just replace it when fitting the stg2? head?

All i can think of mate.

 

cheers mate plenty to check there

rad seems very hot top less warm near bottom,new thermostate when the head went back on new fan switch too, the caps on tight and i still get steam pushing out from it when i turn it off gets worse as i turn it off bubbes and steams

i put a decent amount of coolent in the water too also if i keep letting it heat up will i do damage as im checking for things

 

try pumping the top pipe then the bottom to make a flow,

ie,top squeeze as you let go ,squeeze the bottom,and so on,

could be an air lock,stopping the flow!

mind you ,the impellar on your pump could be away,check the flow first,just a warm engine or even cool will get it flowing,

pump and squeeze,incedently,wots gone on before this happened?

 

i replaced the head gasket because of this problem and bout a new head and didnt fink id have the same problem again did it before but the fan was on constant and still did it when i got the car fan was hooked up to runn from ignition i had it rewired to the fan switch to work which it did but hasnt kicked in when running it the last 2 times just over half way



if the fan doesnt kick in would the water boil ??

only last 10mins before it does

 

ill try pumping the pipes mite have to use a cloth or summing it gets well hot lol

 

defo sounds like an air block,as the air gets hotter,it expands and pushes the water out with gusto,hence the bubbles(just call me bubbles darling!),

get the air out and it should pump around ok.

 

nice one geeza ill av a goo


read ur thread mate underneath looks pukka

 

 

hooked the fan up to constante was ok held a good mid temp and the water was boiling but didnt make the header tank steam went for a lil blip round the block temp went down


i got pretty happy bout that smiling to myself then turned it off

it went nuts and boiled rite up making the header tank steam and hiss ??

now only doing it when i turn it off ????? strange old thing cars lol

 

i get a feeling theirs more then one problem if your fans in all the time specially in this weather it should never get upto halfway so get the fan problem sorted be it a fan switch or some wiring fault as you will end up blowing a relay then meting your fusebox then fookin up your loom if you have bled it and changed thermostat and you are sure their are no leaks then id say water pump could be fooked change that and take it from their

 

take of the small pipe that goes to the header tank and rev the car rite up, water should piss out of this pipe, if not youve got a blockage (rusty rad? or the water pump has failed

 

lol started my engine after 20 plus attemtps and it pissed out when i reved it lol

ive pumped the system
new therostate and new wiring to all fan points as the origanal wiring had been pulled to bits


rad seems ok warm
all over

it pissed out on just tickover too



is the top pipe from the header tank a over flow pipe mine seems to heat up meaning there water going tho it ??


lol i thought i was getting close lol


ps cheers for all ya help and advice guys

 

that means your pump is fine, id take the pipe that comes of the thermostat housing of and the bottom hose of the rad and reverse flus the engine with a hase pipe, do the same with rad until it runs clear.

then fill her up and take her for a spin. if your fans old it mite not be efficient enough. also have you put the multi plug on the fan in the wrong way round causing it to turn the wrong way????

were exactly does the water piss out from, ? (with the cap on) i managed to crack my header tank (by putting cols water in it when it was hot)

this means the system has lost pressure and the car over heats (ive just got a new one from ford Ł24) also try a replacement header tank cap from halford Ł4) this should give the system its pressure back.

check your tank and see if the water is pissing out side of tank.

 

that small pipe comes from the swirl pot (they have one as standerd) when holding revs, water should flow out consistently.

its a breather pipe. not overflow

 

would the fact turning my fans in side the car make any difference as there not even hot just warm when engines overheating

 

when my car starts getting really hot, i turn on my heater fans and its drops the coolant temps (and roasts my balls lol) it sounds like youve got a blockage or air lock on the internal heater side.

 

Deffo got an air lock in there you need to bleed it through

 

lol and now it ant starting at all just turning over

 

Drain the whole system imo, bottom hose off the rad, hose off the thermoustat housing, let it all drain oot and start from scratch.

Makesure the fan is going the right way, and when re-filling take the hose off the top of the thermoustat housing, the thin one and the air will escape that way.
when it's nearing fullness. . start the car up, level might drop a little so top up to max, leave cap off till it starts to get warm (oh and watch for water coming out the thermoustat housing where you took the hose off) put the cap back on, and wait for the fan to come on.

if that doesnt help then go to your local newsagents, buy pack of matches and 1 bottle of lighter fluid

Is the thermoustat fitted the correct way round?

 

yep thermostates sound and the right way round



the lighter fluid and matches is lookin good

 

think you should just sell it and buy a new one

 

DEFO!!! im thinking get a runnabout for few months save up and get a solid sound one

 

good thinking mate dont be wasting money when theirs no need its hard to realise when to stop spending money on a car i used to have a gti 6 as my first car i regret putting so much money into it but if i had took my time finding a mint one in the first place i owuldnt of had to

 

lol very ture mate

 

so air lock it is then!
