Hi All,
         several problems on the new 3.2 heres another .  No coolant loss as yet . Temp gauge runs at 100 /105    

gets to 105 & 1 fan kicks in & brings it down to 95  until it creeps up to 105 again & fan operates again .  This is stationary. 

when driving it is a steady 100.  Difficult to know if its running hotter than normal as car is new to me .  However  cabin

heating will not heat up ,even turning right up to HI   does nothing .  Other end of the scale to LO   the A/C compressor

does not kick in & is not spinning.

Maybe just wants a gas up  . . . but wont do that until I can get the hot side working  first .

Going for a complete coolant system flush including heater matrix & see what occurs 

Lastly  . . . under the header tank there are 2 "heater " pipes going to some sort of electric pump  . . whats is this & should

you be able to feel it is running?  any advice & heads up greatfully received      TIA     Al

EDIT:  forgot to mention one heater pipe is hot as far as the bulkhead  the other seems much cooler almost cold even

Sounds like the matrix is blocked.  give it a good flush try taking the pipes off the matrix and pushing hose directly into it and see if any crud comes out, as for the compressor have you got the eco button on.

As 1 pipe is hot & other cold  . . . matrix blockage seems favorite         ECO  button   is off when trying 

not sure the matrix blockage would cause a reading of 100 +  on the temp gauge though

Won't be able to get on it until next weekend though  . . . working this weekend

Spalling is not my best subject

If the matrix is blocked to that extent it's a good bet the radiator is probably pretty gummed up too, and the thermostat could easily be stuck half closed..

Worth flushing the whole system with something extreme, maybe, if the temperatures don't come under control? Filling the rad (not attached to the engine) with something like Fernox has been mentioned before I believe, then leaving it overnight and back flushing..

Sounds a lot like mine when the radiator and heater was full of oily goop, though, so if you're lucky a thorough flushing might cure it.

Any sign of oil or a stop leek agent in the heeder tank?

if your doing a flush why not change the thermostat aswell,best doing it in the summer than in winter.

the little pump under the expansion tank is the aux water pump, it pumps warm water into the matrix when stopped if you press the off button,runs for about 5 mins. (winter pack)

aircon.. eco button off dials to LO engine running, if compressor no spinny, then not worky. would need regas and pressure check

[biggriffin]

also check vac pipe to hbv.

Mine started overheating a few years ago, but was fine after I flushed the matrix which was clogged solid with crud!

Was thinking the same?, previous Oil Cooler failure. 

Give it a good flush, I would do this this with the Engine running, lower Rad Tap half open so it dribbles out rather than pissing out, hose pipe feed into the Header Tank, when you have the flow balanced rev the Engine to around 2000 rpm now and then with heater on hot and fans blowing untill the (or if) the heater kicks in while flushing, but keep a good eye on the Temp Guage, not too hot as we all know Cold water and over Hot engines dont mix.

no Nothing Chris,  checked all that before I brought it.  Car does not seem to be excessivley hot  . . . just showing 100 on the gauge .  coolant looks a weak mix  though only slightly pink .

Will do a complete coolant flush & maybe disconnect rad  & try to get a flushing agent into it overnight. Car is not required to be in use so no worries about time it takes.

Can anyone tell me what the small electrical pump "thingy" with 2 heater size hoses going to it , does?  and should you be able to feel it running at all?

Sorry forgot to say this is directly below the header tank

Hi Al.

Welcome to the world of 3.2 and hope you enjoy ownership as much as I am with my new Elite.

The small electrical pump under the coolant reservoir id for the "winter pack" and is designed to push the warming coolant through the matrix quicker on start up allowing for a quicker warmer cabin.It also allows coolant to be pumped around matrix when and after stopping engine so again cabin stay/keeps warm.Not too sure how efficient it is as havent needed to use mine in the winter months much yet.

When I first got mine the temp gauge would barely move off the bottom stop so first job was the thermostat which has cured mine.In your position I would ,as advised by others ,give the entire system a very thorough flush,even remove radiator and fill with descaler,as its not much of a job taking the radiator out.It will also give you a good chance to clean out the fins of both the main radiator and a/c rad too as they get blocked with flies/debris etc.

If you are in no hurry to get car mobile I would also replace the thermostat/housing and give the fan thermoswitches a good test to ensure they are functioning correctly as there is lots that can cause hot running /or the inability to bring temp down correctly.

Once I had done a thorough refurb on mine the temp gauge now sits dead center and has never gone higher even on the hottest days this year so far.From cold she gets up to temp in just a few miles ,so mine was cured just with a simple process of elimination.

Good luck with it
