All these offers of cheap radiators for you mate......

...reckon they should bring out a program called...

'Everybody Loves Radders'



P.S. Glad to see it wasnt just me who thought about the swelling radiator due to too much pressure...but RSNissan seems to have squashed that possibility by stating that they have a habit of leaking there.......

 

strap it ala r5gtt intercoolers

 

Headgaskets gone! Fitted another radiator this morning, didnt even get 2 minutes away from my house and the rad went pop!

 

 

sorry to hear that buddy, do you have to buy another RAD now?

 

unlucky mate, i was gonna say that the pic of the rad youposted looks like its pressureised ie h/g gone

 

I hate to say it........ but

I did tell you so


Hope you get it sorted soon mate

 

Radders, how much has this thing cost you in repairs etc


just hope it is sorted for once & for all!

 

oh oh spaghettio

still stick at it keep it get it sorted then it will be fine

 

Dont even wanna think about it at the mo... Im just eyeing up a noose and the banister rail

 

I think we should use this thread to highlight the fact that the car owning grass isn't always greener on the other side .

 

My sides Mike, They hurt, They really do...

 

Chin up, at least it's not a Skyline, as the "tax" on those is even more than "Cossie-tax" .

 

that's great news Rad, could have ben something a LOT worse, a gasket is only a service item really....it's just a shame they aresuch an arse to change.

it'll be sorted soon i'm sure

 

Not that bad really mate , just a pain in the arse as everyone say's.

Get it sorted and you can break the box

 

didnt you say the compression test you did the otehr day was fine though?

 

Shit luck Rad!

Take it the HG has gone causing pressure to build in the water system and POP!

Shame it was a new rad! I would be sneaky and try and return it saying 'Look at this hole, i want another one!' LOL ...

 

I think he has done that already

 

Ah well Rad, as ive said before that was the first thing i said to you when you rang and told me the pump had failed.

Relieving in a way though i'm sure, gaskets are cheap as chips the standard ones are good for quite high power

And at least now you have quite a good knowledge of whats good on the car and hopefully now have some faith

 

.....yeah the gauges work well!!!!

 

do i detect a spot of sarcasm

 

all these other failures are just "warm up acts" for the main event of the gearbox shitting itself once you get it running right

 

Are you sure its the headgasket?

Have you checked the radiator cap? It should release the pressure into the expansion tank well before theres enough there to make the rad go bang

 

Cap was fine mate...

 

Might be worth doing a leak down test.

 

well at least you have found the problem.

get it fixed then book it on the track before it breacks again.

 

Break it whilst you can and then buy a reliable car like a






































FORD

 

is it fixed yet?

 

Taking the piss?!

 

I agree!!!

Although the headgasket may well be gone, the releif valve in the radiator cap should have pissed out all the excess pressure!

 

Oh I thought you meant fucked in general.. but yeah it did.. the header tank was full...

 

not been on the computer since this afternoon, and knowing what an industrious chap you are, i thought you would have had it done in a matter of tea breaks and would now be hooning it around the streets of uxbridge upsetting the local oldies

 

Na fuck that

Had to wait around to get the glass anyhow

 

the header tank will still be full, but the reason your radiator has blown is because the cooling system is being pumped full of exhaust gases, thus pressurising it excessively and blowing the radiator.

There is a pressure releif valve built into the cap which gets rid of this excess pressure (gasses, not water), so the system will not over pressurise itself. If the releif valve has failed, the excess gasses cannot escape, so the system will build up a lot of pressure, and eventually blow the weakest part, i.i. the radiator.

Have you ran it on tickover with the cap off to see if you have bubbles coming up through?

 

Surely the cap can't tell the difference between 20psi of water and 20psi of air, so it will open and allow either to escape.

The overflow bottle isn't sealed, there's a vent on the side of it which would allow excess water/air out (assuming it isn't entering faster than it can leave if there's that much of it)

 

The size hole needed to allow gas to escape is larger than to allow water to escape, so it doenst work quite like that.

 

don't forget that the gas is lighter than the water, so the gas will rise to the surface and escape, not the water.

 

Does the pressure relief on this have one of those very long and extremely thin pipes like most Nissans do by any chance?

 

What do you mean? There's a long thinish pipe from the rad cap area to the overflow tank, if that's what you mean.
