Been having a few problems with the cooling system and to cut a long story short.


Fan relays stopped working the car ran hot around 110c (No Stop Light)

Matrix went pop replaced with new unit and then the matrix pipes broke getting them off replaced with decent
secondhand pipes.

Bled the system x 5 and Snapped the thermostat bleed screw undoing it the system still kept losing all the
coolant within a couple days.

Replaced the old rad with a new Nissens alloy rad with a new lower pipe to match.

Coolant seems to stay now but the 6 sat unused for a day then 2 days but there was still enough pressure to lose a small cup worth of coolant when I took the rad cap off each time.

Bled the system couple more times.

Once its bled all seems ok but after its been used and then sat for a while then started again with a few revs I can here water rushing back into the matrix cant remember is this normal ?


Is there any reason apart from Head gasket on its way out for pressure staying in the cooling system ?


If the system is overfilled with the cap put back on will it just loose the extra coolant through the overflow pipe on its own ?


Cheers for any help !

Just seen your in kent. Where you from?

Where bout you live then Arron and what you got ?

I've been thinking HG but just want to rule out every thing else first.

Im from maidstone. Here's my china.


What you got matey?

Your problem does sound head gaskety indeed. And if left could blow alsorts. Will pay you too get the car sniff and compression tested.

Then... drag yourself to a kent meet

You could meet loads of us. Its good social seen umongst the kent lads as most are based in maidstone or medway.
Heres some of us.

You'll be looking at around £500 all in i reckon. And yeah, the head will need a skim for sure and pressure test too. All of which should be included in the price.

Shame to break somthing so nice. Put the money in to it now and it should be reliable for more years to come!

I agree. Get the gasket done if it is that and the car will probly be fine. What other stuff has gone wrong with it?
Looks lovely by the way. Suprised iv not seen it about.

Well got the sniff test done theres no hydrocarbons in the coolant thank god ....

Hopefully there was just to much coolant in the system even though I did drain to half way down the expansion take maybe needed to settle down and further draining.
Will see over the next week if the matrix blows cold again hopefully it could of been slightly over filled.

If not I'll get a compression test done.

Fair enough. Compression test should be done anyhow really. Did the garage say what might cause the system to stay pressurised? Did they bleed the coolent at all? Good start though.

Now... Get that car out!

sounds like the head gasket to me too. When mine went it was blowing inbetween the cylinders and also into the coolant system so whenever i ran the car it produced a huge amount of pressure into the coolant system.

When the car was switched off the pressure was then pushing coolant back into the cylinder causing a missfire on start up because one of the cylinders had moisture in there. This cleared after a few revs and the moisture was burnt off.

Before I got the headgasket fixed - when id stop the car i used to slowly release the radiator cap to release the pressure build up and that stopped the missfire.

from what ive heard there is only a certain amount of times you can skim the head - apparently theres a mark on the head to indicate the maximum you can remove, dunno if this is correct or not

I suppose it could well be doing what your saying but theres no misfire at the moment so unless the coolants not making its way back into the bores, did you have any trouble starting it ?

Sounds good google says only half an hour away from home I'm used to the journey work that way near Headcorn.

Going to put my bleed method up and bleed it again this weekend see how it goes next week first.

you go a name and number might give him a bell ?

Went out for a meal for my bros 21st Newnham court you know it ?

Well my headgasket was in a dire state and didnt show any of these symptoms. Only pressure in the coolant system.
