Re: Frustration with water pump change.

On the Sei MPI is the rad fan controlled by the ECU via the engine temperature sensor?

Re: Frustration with water pump change.

Ive decided to flush out the whole system.
I want to clean out the reservoir so will take that off.
can i put a water hose into the pipe from the reservoir to the rad and turn the engine over and it will circulate back to the small pipe at the top and drain out?.

Re: Frustration with water pump change.

So... Today i whipped off the coolant reservoir, cleaned that up. Flushed the entire system for 1/2hr and added coolant ( red this time ).
Got it up to temperature, bled it all until i could see the red fluid coming out.
Tick over is great, no steam out the exhaust and it seems the overheating is now under control.
BUT.
This car has gave me a final kick in the plums by not reving over 3000.
No EML, took off the positve off the battery for 1/4hr, but still the same.
Read the codes and have 4.
P0300 - Cylinder miss fire Generic
P0135 - O2 sensor circular bank 1 sensor 1
P0340 - Camshaft sensor
P0120 - Throtal/pedal position sensor switch A
Now i cant see that all of these sensors have gone doolally?.
So it maybe 1 that is throwing all the rest out, disconnected the front manifold lambda sensor and when restarted nothing changed and still no EML and didnt rev.
So it might be this one.
I have an MOT for Friday as its already over a week overdue, and although it pains me i might just let the Garage sort it if its not something i have missed.
Any clues guys?.

Thank you for your reply David.
But it would be great if you could elaborate more with your answers.
Just for the less gifted spanner turners, myself included can get a more fuller idea of where and what we should look for.

Re: Frustration with water pump change.

The engine earth is ontop of the gearbox.

My guess is the water might have upset something?

Disconnect the battery for longer and hopefully it'll be ok with a virgin ecu.i don't think 15 mins is long enough. Needs to be a few hours I think.

Was it revving over 3k before it overheated?

Re: Frustration with water pump change.

Thanks purf.
Yeah revs were fine when i gave it a road test after fitting the water pump etc.
I did think the water may have caused the problem?.
I had to do the flush on my MIL drive and washed the drive and underside of the car thoroughly to clean up all the gunk and coolant.
Unplugged and cleaned the crankshaft and front lambda connections after though.
May have a drive up there tomorrow and see if its dried out.

Re: Frustration with water pump change.

Water certainly won't help.

You can never have too much earth, so if in doubt, add additional earths from engine/trans assy to the shell.

Cheers

Re: Frustration with water pump change.

Well i got some good news.
Car passed its MOT yesterday with no advisories.
They were too busy to do a check into the revving issue, so will have a look into it myself.

UPDATE:
Well it appears i may have fixed it.
I remembered i had a box of car stuff in the shed ( we all have that box dont we?).
In it were some sensors i had changed on various Cento's, found a Magneti marelli crank shaft sensor and a Delphi O2 sensor.
Tried the O2 sensor, made no difference.
Then the crank shaft sensor.
BOOOM, up she revs.
Took it out for a drive and no issues.
So i guess what may have happened, is when the reservoir popped the coolant had got in somewhere and fried it?.

Thank you.
Next, errr??
I plan to run it and enjoy it.
All the Cento's i have owned (4 now) have been as a daily driver to keep the miles off the Alfa's
But i do love em and put the same kind of care and attention into them as the expensive ones.
So maybe a clutch if my left calf gives in.

Re: Frustration with water pump change.

Bugger bugger bugger.
While i washed the car today i thought i would check the levels etc.
Expansion tank was almost empty?, so topped it up and turned over the car.
All seemed ok until i could see it was dripping at a fair rate under the car.
Looks like (i haven't investigated further) the new water pump i fitted is leaking.
Question... I guess i can whip it off again and reapply some sealant ?, i know the gasket will be no good to refit.
Has anyone just refitted with sealant?

I thought at 1st i might have over filled it with coolant as i topped up to the max.
Ideas guys?
Are you over-thinking it?

If there's bubbles coming out after a complete pump/coolant change, then it could just be the system is purging itself as it is designed to do.

If it's not overheating on the temperature gauge and the hoses aren't rock hard and no fluid is being ejected from the header tank cap (which will release any pressure over 1.2 or 1.4 BAR, depending which type you have).. then what's the problem?

The bubbles ought to disappear fairly quickly, as all the air is vented out... then Roberto will be your mother's brother...
