Boiling in coolant expansion tank...





Have a feeling that its not necessarily good. I seem to remember hearing from somewhere that its symptomatic of probelms.

Any help appreciated.

This happened to me on my first 1400 RT, (I didnt know much about cars then and opened the lid, didnt know it was pressurised and it sprayed everywhere doh!!) it was my thermostat that was fecked.
 


Hmmm...new thermostat was fitted 16k miles ago...

BTW Colin, what sort of wheels have you got on your Maxi - and how did you get them to fill the arches? Spacers? Mega offset?
 


Mine does it too, and the area around the tank is a rusty colour, it cant be a good thing, i wouldnt mind knowing what it is though.
 


if it was a gasket, i would check the exhaust for vapour, plus for fouling, water for oil and oil for water, but its all the basics. No leaks?

serious bubles? or little teensy ones?

Technomag F1s in Peugeot fitment as well as spacers/hub converters. I wanted 8.5x18 on the back and Renault fitment wasnt available in that size. Also Pug wheels have a low offset. Working out those wheels has been a right pain in the arse!!! Nick G has a Dimma Clio and he is getting the same spacers as mine but thicker and putting Scooby wheels on and they have a very high offset even higher than standard Renault. Spacers is the way to go as long as you get ones that bolt onto the hub and keep your hub centric you should not have a problem. That is what Dimma told me and Nick. Dimma do them for £350, but I am getting the powerflow round the corner from me to do them for £200.
 


The bubbles are fairly big, in comparison with kettle bubbles anyway.

Theres also masses of vapour from the exhaust, but I think thats pretty normal at this time of the year. Theres no water in the oil and vice versa.

I went through all these checks a few weeks ago when my engine spat out a spark plug and I didnt find anything odd then (must have been a loose plug). The idling of the car still goes a bit dicky from time to time, though thats probably an ignition/fuel system fault.

Colin: thanks for that. Im running into some dosh at the end of the summer and am wondering whether to turbo or Maxi my car. At the moment its Maxi thats got my attention, since my car isnt exactly a slouch anyway. But if I get any major engine trouble before then, itll be a turbo for me.

The Maxi looks awesome but if I could afford the High Pressure Turbo it would be that all the way without any doubt.
 


this site really fecks me off at times, yet again i type a detailed responce and go to post and it fails and the posts is lost,

anyway will talk sunday, have a few possible ideas, try removing and refitting the filler cap when stone cold to start with.
 


No water loss, although there was a minor leak from the radiator a while ago (radweld cured that). Cheers guys, will try the ideas this morning.

Lofty - Im probably going to cycle over to yours as my car is shacked up behind two others in our alley/compound at the flat in Bristol! PM me when you have a time.
 


Errr...Pucklechurch? Let me get the map out

...er...no! Im not in that case! I thought Lofty was near to Keynsham for some reason.
 


i can drive out your way no problem, name a convienent place, i was thinking about 11am, yes Pucklechurch is where it all happens!
 


LOL.......

pucklechurce is quite an amusing name.........

and yes, Lofty, you live way too far out from all the action!!!
 


Hey Lofty! Do you think you could make it to Whiteladies Road, near to the BBC? :D

I did a study of the Pucklechurch LETS scheme a few years ago - where people trade their services (like haircuts, homegrown veg, car mechanics, babysitting etc) for credits - and you redeem these credits for other services in return.

Sounds like a big hippy place to me!:D
 


Pucklechurch is alright, agreed with BenR its a bit isolated but most of the time thats nice, byt then again without traffic i can be in the centre in under 15mins,

so yes Ben name a convienent place round whiteladies where you can park a bike.

The barter economy was rife in the tyre place and i like it, but i have seen no evidence of it in pucklechurch itself, must be the inbred yokal hill billies, who i avoid.

starter stalk and anything else ben? i have a complete throttle body and inlet minifold i believe including the idle controll valve, hours of fun, and cheap.

I found radweld to be very unhealthy for your radiator system, can cause clogging and slowing of the water flow to the radiator, hence the fact the water is overheating.

Also check that your cooling fan is cutting in at the correct temprature. Do a full radiator flush just to get the radweld crap out of the system.
 


Lofty: well, erm, Whiteladies Rd is actually where I live! I live on Melrose Place - as you go up Whiteladies, take the left literally just before the old ABC cinema (just after a BP garage on your left).

If you reckon thats OK then Ill give you more details. The postcode is BS8 2NQ (pop it into http://www.multimap.co.ukwww.multimap.co.uk) and I live at the back of no.13.

Just the starter and stalk Im afraid! I already have loads of things to do!

_KDF: the system was flushed and a new header tank fitted about 5k miles ago, when I stuck some radweld in because there was a little leak from the radiator bleed screw. It was enough to go from "max" to "min" on the header tank within 1000 miles. So I guess I just have to live with the downsides to Radweld or get a new rad. The thermostat and other sensors are all pretty new and work OK.
