Still got bizarre overheating problem PLEASE HELP

[tylerma]

well naturally when you turn the heater on it brings down the operating temp of any normal running car

after all it is all linked

but when i had a split in my rad it was doing some strange things

[Dan318-is]

maybe its worth replacing rad first then considering its a piece of piss compared to heater matrix pipes

[tylerma]

you could do
its just a suggestion after all

dont want you sparking me out at the Ace
if i am wrong

[Dan318-is]

lol i wont do mate

thing is winter being heren all i can livce with it

i drove to ace n back with heating on an it was warm an didnt flinch

an i did 120 past a honda lol

[tylerma]

cool
well maybe a few of the gang can look round it when you get to the Ace

a few heads under the bonnet might spot something

just out of curiosity how far does the needle go over into the red when you dont have the heater on

Mine had the same problem, so to find out what was the problem I joined the two pipes going in and out of the cooling system inside the cabin (pipes the go inside the cabin to the heater matrix that is). And voila, I discovered that the overheating problem disapeared...
To access the heater matrix all you have to do is strip the middle console and you can see the heater matrix pipes. Then decide where is the problem !
I hope this helps, it helped me !

[Dan318-is]

strip the console

think thats a weekday job

cheers mate

[JOSEMI]

Just a last tip - bleed the cooling system after you join the two pipes in case there is air in it...

[Dan318-is]

how hard are they to get to mate?

You probably released the airlock in the process. Would probably have had the same result if you just connected the heater pipes up again.

[JOSEMI]

In my 320 they can be seen as soon as you take the middle section out on the left side, the pipes are of a white-brownish colour (probably produced by the hot water circulating in them). In my case they were cracked and flooding the cabin ! i bought them second hand in perfect state in ebay, although they shouldn't be 2 expensive in the stealers...

Something I've thought of that could do with repeating here.
Many years ago there was a recall for E30 cooling ststem pressure caps.
The problem was they became faulty and over pressureised the system, causing all sorts of leaks.
Remove your pressure cap, and check the centre disc right at the bottom is yellow, not black. If your's hasn't been changed then get yourself down to your dealer with your VIN, and you should get one FOC.

[JOSEMI]

good one, will do - E30's overheating can be hell if not taken care of
cheers mate !

[Dan318-is]

im guna check that in a minute

but replacing that aint guna fix my problem no?

[JOSEMI]

I would say that if any of the pipes fo the system is already leaking then no

[Dan318-is]

thought not

il try n get them wednesday n do it unless it rains then

i need some bits from the stealers n e way

il let ya no mate

if it aint them what could it be?

[JOSEMI]

Dop you mean the pipes or the rubber caps ?

[Dan318-is]

il get both from the stealers but i mite have a new cap already, i remember it being yellow, or is that just me imagining?

could a dodgy radiater cause this to happen also?

[JOSEMI]

The problem in mine did originally start with a blown rad... air got in and the overheated water then blew the matrix heater... a nightmare of a week... check that yours is not leaking anywhere.
Also check that water reservoir in your car with regularity, water is a must to keep the engine cool

[Dan318-is]

i check it like 5 times a day when i use it mate

got a litre n half spare in the boot - extra weight tho

il try matrix pipes first on wednesday i htink

thanks for your help everyone
