hey all, T reg Mondy ST24, 149k on the clock, only had it couple of weeks an so far been perfect!


coming home just now, suddenly noticed that the temp gauge had risen more than normal, an within like 2 minutes it had gone OVER the red and saw a trail of water as i parked up, had a look an it was boiling over! so popped the bonnet and it was bubbling a good'en!!! its now left to cool down an the water bottle is slowly lowering again!?!?!?!?!

am i looking at head gasket? engines been running smooth as anything, no mucj in the oil, level has always been on max (ish) the few times ive checked!

 

have you checked all the water hoses for splits?

joe

 

no not properly, its all too hot at the mo, but what i did notice that was very strange is that it was overflowing from somewhere on the header tank (if thats what its called) but NOT, NOT from the cap???? it looks like it was coming from behind the bottle somewhere, near the rear bracket that holds it to the wing??? have got pics of where abouts if that helps???

 

put pics up mate

 

When the water in the tank was bubbling, it was leaking from just up behind this bracket and not the cap??




oil fine on the dipstick

and the cap

 

i got a 30 sec video of it bubbling away too if needed lol

 

sounds like the header tanks split for a start. check your fan switch this happend to one of my cars and it ended up being the fan switch. if not obviously the usuall test to see if headgasket is ok.

shall i chance filling it back up once its cooled down, an running on tickover an see if the fan kicks in?

 

are you at home our on the side off the road? like s1cab said sounds like header tank has split.

 

yh crawled home as was only 2 min away! and now i think back, i dont remember hearing the fan kick in?? have heard it before, usually when temp gauge is a little before half way, an its quite a distinctive noise???

 

i would dry every thing off and put newspaper down under engain bay fill back up with water and look for drips or and sign off leaking. if none found turn on and wait for fans to come on while looking at temp gauge if not kicking in at usall temp you not theres somet wrong.

joe

 

ok mate thanks will give that a go, its fairly cool now (compared to what it was) shall i put warm water in as the blocks guna still be a bit warm??

and the tanks not split, it looks like a drain hole on the inner of the top of the tank, looks like a overflow thing to save it bursting out the cap???? can show ya on pics if needed but it defo not cracked

 

can anyone tell me where the Fuse for the cooling fan is situated??

 

thats boiling in the vid ! so either headgasket or fan switch. check the fan switch

 

youre just to good for grove garage now!!!!

 

well its ticking over! no leaking, water level staying put, temp gauge slowly on the move but not even quarter of the way yet! done a few vids of sound of engine etc so put them on in a bit!

 

looking at the swelling of the to little pipes going to the headder tank and the fact that you said you was driving along when it over heated i would be tempted to say that there mite be somethink bit more a miss than the fan switch

 

Right............

temp gauge went sky high again, even though the fan kicked in here:



it then within few minutes went to here:


even with the fan still running!!??!!??

what i did notice is that when i put the fan on hottest setting, it only blew out cold air??? and that under the bonnet, the top 2 pipes going into the header tank were extremely hot yet the engine was touchable? water level started to raise slowly, and the radiators also cold????
(see vid)

The Mondeo V6 is reknown for breaking the plastic impellar on the water pump, this could have gone, meaning the water will not circulate around the engine properly. Get the engine checked properly before running it again, the least that could happen is the headgasket going, with the worst being the engine being scrap due to warping. If it is the water pump get a metal one and change the thermostat at the same time, over heating tends to take them out as well. Saying all that though make sure it isn't just a broken auxillary belt as well, could be that simple, fingers crossed for you.

 

position of the Aux belt is where lol! dont know a thing about these engines!

 

Oh and if the airbag light is flashing four times it will be the yellow plug under one of the seats, take them out and clean then connections, then cable tie them back together. Before undoing them disconnect the battery for half and hour to discharge the SRS system.

 

as he says mate

 

On the right hand side of the engine, just a little belt that runs the water pump, not the huge belt that is on the left hand side.

 

I am now sitting in front of monitor, holding in my hand "said belt"


*you da man* lol

 

 

That'll be the problem then, easy fix

 

it was the belt then lol hope no more damage is done then

 

i hope so! whats the correct name for the belt? cant seem to find it online? easy fix for someone not knowing these engines?? ive had rovers for the last few years an done everything you can think of lol but this engines a maze to me lol

 

yup! i hope not too! engine was ticking over fine still when i topped it back up earlier, didnt sound any different to before so fingers crossed its not warped the head or anything!

first thing i have changed when i bought both my V6 mondys, is the water pump to metal impellar, and a brand new water pump belt from ford. mine VERY rarely goes past the N on normal on the temperature gauge.

as for having no mayo on the oil filler cap, header tank cap, and dipstick, they very rarely do when the headgasket goes on the 2.5 V6.

 

nice one thanks peeps, ya all been a great help! off to maidstone in the morning so will track one down on me way an fit it (hopefully) when i get back!!

 

yeah this is what i was worried about as read a few people saying it doesnt always give a sign i.e mayo/sludge!!
luckily when i looked, the belt was just hanging there! think ill replace it an get the waterpump changed asap!!

 

get the water pump from your local partco, tell them you want the metal impellar one, its about £47, and a new water pump belt from ford is about £10, as said, ive bought both either the same day, or the day after, i bought both my V6 mondys. for the sake of £57, and a half hour job, if for nothing else, you have peice of mind.

 

yep, defo worth it! is the water pump easy (ish) to do?? ive done it on a rover 25, that was a B***CH! as had to remove cambelt to do it! lol

 

thermostate or water pump replace these mate done it loads of times defo the prob and get a new fan switch

 

has anyone got a diagram of the actual assembly?? i got the belt but looks to me the tensioner was at fault as the bearings are hanging out lol!! and so far been quoted £80 from ford for a new tensioner???!!!???

 

is there also anothe name for it or anything?? have tried a few different places and when i say "the water pump belt tensioner" they all reply.... "THE WHAT"????? its like talking to a brick wall!!
