HELP!!! My car went into a garage because it was overheating and building up pressure in the water bottle. The garage said it was the head gasket, they replaced this, had the head skimmed, but it still has the same problem ie: overheating and building up pressure. The mechanic has told me a valve has broken and corroded in one of the hoses, which is causes the overheating. The garage say there is a one way valve in the hose going from the thermostat housing to the heater exchange and this is what has broken lose! This caused the overheating which caused the head gasket to break. Has anyone heard of a hose that has a valve in it? It all sounds a bit far fetched to me and the garage still have my car, are refusing to give it to me until I pay for the work they have done, fair enough, but they haven't yet fixed the problem. :(

Ive not heard of that happening. Heater control valves do get stuck, but dont normally cause the engine to overheat.

I do know of garages changing head gaskets when the only problem was the expansion tank cap not holding the pressure. This includes my Father in Law who had a garage replace his only to find it was still over heating.

Garages often do a pressure test on the cooling system. When that comes up clear, they assume that it is a head gasket without testing the cap. If the cap is not holding pressure the coolant boils at a lower temperature, it doesnt circulate and you get the problems you are experiencing.

Other issues could be a thermostat that is stuck closed, blocked rad, collapsed hose on exit from rad to water pump or water pump siezed or broken.

I would just try changing the expansion tank cap just in case it is that.

have changed the thermostat and cap. I was wondering if anyone has heard of there being a one way valve in the hose that goes from the thermostat housing to the heater exchange. The garage said this breaking away and getting jammed in the hose caused the damage to the head gasket.

Sounds like a load of shoemakers to me. :)

Petrol or diesel??

I have a haynes manual I could check for you.

When the engine is cold give the hose a squeeze with your fingers along it's entire length. If there is anything like a valve inside it you will be able to feel it.
I know many many years ago some manufacturers used thermostats that were located inside hoses, not sure if this practice still exists though.

You could also pop into ford and ask for a price on a spare part, give them the description the garage gave you of the item and see if it is stocked! They also have very good exploded diagrams of your engine which you could use to identify the parts existence (or not).

Other question is why would you need a one way valve anyway??
mcbutler
Another relevant point.

I would not expect an overheating engine to be the cause of a failed head gasket unless you had reached critical temp and seizure of the engine had occured.
These gaskets operate continually at temperatures far exceeding those of an overheated engine. The inside edges of the gasket are in direct contact with the burning pressurised fuel at temperatures around 1200 deg C plus

Thank you for the advice, my car is petrol 2001 ford focus estate zetec engine. I think I have found a garage full of cowboys :( I rang the ford dealers they said it doesn't say whether the hose I need has a valve in it, I did have my doubts because why would you need a one way valve when the water only gets pumped round one way!!! I am stuck now because they won't let me have my car until I pay them and I don't want to pay them because they haven't fixed the problem. :(
Stoney871
If they haven't correctly diagnosed or fixed the problem they can't expect to be paid any more than for the time and parts already done, strange they only did work that can't be reversed or removed, if you weren't happy with an installed part you could make them take it back off again but obviously they can't stick metal back on the head and a gasket is nothing.
Send in the indians i say (trading standards)
anthzm
have contacted Trading Standards they have logged a report and taken the garages contact details, so if there have been any other complaints i'm sure it will get looked in to. :) The garage said to give them until Monday to fix the problem, so I guess I just have to wait. :(
mcbutler
I would give AA or RAC a call to, are you a member of either?

I have flicked through haynes, no mention of anything like it in there either.

Keep us posted Anthea, be interesting to hear the result, also we all want to know if they are cowboys so we can avoid them.

I am pretty sure they cannot withhold a car worth thousands against a repair that is worth a few hundred.

Might be an idea for this site, a black list of dodgy garages..
Stoney871
Sounds like the sort of place that tells you that the air in your tyres needs changing and your indicator fluid is low.
Robbing gets.
anthzm
will see what Monday brings!!! my car should be fixed... apparently!!!
I am a member of the RAC. Thats a good idea to ring them.
Once I get my car back and hopefully fixed, I will name and shame them.
mcbutler
Any news Anthea?
jeebowhite
has they magically fixed the valve yet? I say ask them for a quote (as stoney said) to change the air in the tyres, see what they say... maybe, after you have got your car...
anthzm
well I eventually got my car back yesterday, they rang at 2.40pm to say it was ready, I finally drove away from there at 4.45pm.
The garage quoted me £530, but when I went to collect the car it had gone up another £100. Me and my husband refused to pay because when one of their mechanics took it for a test drive at our request because they hadn't actually taken it for a test drive,
The so called pipe that has the one way valve in it? looks like a new pipe and you can feel something solid about 3 inches long in the end nearest to the thermostat housing, so i'd hate to imagine what they have done!!!
The car was running worse than when it went in. They also said the clutch was slipping, there was nothing wrong with it when it went in.
Anyway the boss of the garage got quite verbally abusive and the police had to be involved as the situation was getting a bit heated.
We ended up having to pay, but only had to pay the original price of £530 and driving away with a car I can't rely on, as I don't know what they have done to it!!!
I have learnt my lesson and in future will pay the extra money and go to a proper Ford garage. :(

ps, Thank you to everyone for all the advice. :)

They used to be a really good garage, but have recently been taken over by new management, who aren't nice. The boss is manipulative, dishonest and a conman.

Omg thats disgusting, I know the garage and they are shocking, intact I'm on my way to do my Cbt which is round the corner from there. Utterly disgusting that you had to call the police, I would not recommend going to Ford however I have a good mechanic in twickenham and a good mechanic.in staines if you want their details they Probs won't charge for having a look over it.
jeebowhite
Good Idea, get it checked over by someone mutually trusted so that you know what is happening. Sorry you had to get the police involved, its a crying shame when things like this happen.
anthzm
I wish I found this forum before I took my car to the garage, would have saved a lot of aggro :(
If you can recommend a mechanic I would be grateful, as recommended mechanics, builders etc is normally the best road to go down.
Z3 MON
I have done mechanics and do know the focus engine fairly well.(my brother still has ours) if you want I can take a look??? I pm'd u the two bloke I use for the work I can't do on mine so u can give them a ring ??

If you want me to have a look pm me

I thought I would post an update on my car situation. Since getting my car back it has been running really sluggish and when you go to pull away the car would hardly move, it would then kangaroo jump down the road before getting a sudden surge of power and suddenly it would go.

Yesterday I was driving it and the engine management light came on, so I decided it was time to take it to a proper recommended garage. They put it on a diagnostic machine and it turned out I had an old ignition coil on it, which was blue and from a car of the same model as mine, but a lot older. It looks like Bedfont MOT Centre took my one off and replaced it with a dud one. The one they took off was replaced by the same garage about a year ago!!!
Stoney871
Very fishy if you ask me.
I'd confront them over it and threaten them with Trading Standards.
Take the old unit with you and advise them to insert it somewhere unpleasant.
Pauly
hope you paid by credit card then any subsequent issues they should have fixed would be covered by consumer credit !

Hi

Fistly I would talk to the trading standards again...i would also defo look at smalls claim court...they will see it in your favour no questions asked...small claims dont like hooky garages.

Like someone else mentioned whenever a car is overheating you must always start at the easy things ie Pressure cap...I teach Audi/VW apprentices and paramount in my job to create a decent technician is to get them to start simple....creates cracking customer satisfaction and right first time fixes

i also seen nobody mentioned the old ford cookie of an "airlock"...especially when the head has just been change...normally garages will fit a head gasket and top up water fit cap and leave it....when you should keep the rad cap off till the stat opens and the fan cuts in...you will normally see the water drop as its getting rid of the air in the system, top up with coolant and airlock gone....garages play sneaky moves changing a part to make out something was at fault..when it wasnt.

This advice is for anyone taking a car to a garage and I will use this as thread as a cracking example...if they ring you to tell you that the head gasket needs changing then tell them to stop work as you want to visit the garage for them to show you where the headgasket has gone...and if they say the head needs skimming ask for a full explanation why...the head should be warped for it to need skimming a straight edge would confirm this. put it across the head surface any gaps it needs a skim....alot of garages use this technique to make more money....then I suppose you got stitched with stretch bolts for the cylinder head...these can be used once more after being removed so if your mileage is on 50k and the head has never been off before then the head bolts can be used one more time with no worries.

Like mentioned trading standards..Small claims....and if my memory serves me correct if they do a repair that doesnt fix the problem then they should refit the old parts if this is not possible ie head skim/gasket all you need to pay for is the price of the skim and the gasket not the labour...their mis diagnosis is at fault not you....Mr/Mrs Layman

Hope this helps

Thank you everyone, but for me it is to late this garage have well and truly mucked up my car. Even now the engine sounds as if it wants to stall, when my lights are on the engine runs rougher and when I rev the car my headlights flicker :(
Whatever the garage did I don't think I will trust my car again to travel distances :(
I have rung Trading Standards again, they logged the further complaint, incase there have been other negative issues against this garage.
As for the small claims court I would love to take them to court, but unfortunately finances will not allow that at the moment.
I feel sorry for anyone else that has the misfortune to go to this garage and I wish there was a way to warn people!!!
DO NOT EVER USE BEDFONT MOT CENTRE...
