Hello everybody
this is my first post and I'm looking for help on the correct bleeding procedure for my Multipla 1.9 MJT 88KW (2007)
I changed by myself timng belt and water pump
When it was time to fill the cooling circuit I found only 2 screws on the rad, one on bottom right, the one I used to empty the circuit, and one on top left facing the front of the car.
I made flushing and filling of the circuit with heating closed.
Filling took about 4 Liters of coolant liquid, the handbook says there shoul be 6.6 liters...
Is this difference due to heating circuit closed durin flushing?
The display bars on the control system are 3 at max..

Where is my mistake?
I saw a returning pipe that enters at top of coolant tank and it shows liquid with bubbles.

Is the system auto bleeding or are there other bleeding point along the circuit?
Thanks for your help
Cheers

Pietro

Today I found a metal pipe in fron of the engine with a screw on it for bleeding.
Once opened no air came out..
I travelled for about 25Km and outside there are 13°C. The temperature indicator stood at 1 mark..

Here are the three bleeding points I found.

This morning, after 3 cycles of cooling fan activation, the cooling fluid level didn't change.

I didn't find any purge valve on the circuit going to the heating matrix

Is this circuit autobleeding?
Thanks

Recently swapped engine in my 1.9jtd amd also changed water pump and cambelt, don't remember having to do any bleeding apart from running and topping up as well as letting air out at screw on that metal pipe. Are you sure thermostat has not failed as its very similar to ones used on Alfa diesels and they were prone to going, changed mine on 156jtd and a bit fiddly.

Hello Thanks!
I'll see if the temperature doesn't rise using my car.
Today temperature rised to the point that the fan starded to spin and temperature gauge showed 4 tiks.

I'm a little scared because I flushed the cooling circuit and then I filled it with 4 liters of coolant..
I made the whole process with heater matrix circuit closed.
So is it possble that 2 and half liters have been there inside and didn't run off the circuit?

I think thermostat has gone ..
Today 10 ° C outside and 1 tick on the temperature indicator ...
The heater did not blow very hot air, just "tepid"
Last week I changed timing belt and water pump, together with V belt and idlers
This week thermostat
Next week clutch and flywheel..

This car has put happyness in my life

Are you sure you completely drain ed all the water out of the engine and radiator? If you just removed the water pump or bottom hose its possible only part of the coolant was drained hence less than the quoted capacity to refill it, heater radiator will hold 1/2 litre or so of water. Plenty of guides on how to replace clutch on here.... good luck.

Hello
today I changed the thermostat.
I removed all the coolant by removing the stopper screw from the bottom of the radiator. The heater circuit was opened.
3 liters came out more or less, some coolant went on the floor so it wasn't collected and taken into account.
Then I set the new thermostat and refilled the circuit.
After the complete heating of the engine (cooling fan was running two times) and a long trip around here, 4 liters entered the circuit.
Now the car runs fine, the temperature indicator shows 4 tiks all the time. Before it was between 1 and 2 tiks.
Thermostat is working correctly I felt the engine hot and radiator cool. After a while the radiator became hot too so the thermostat opened the rad circuit.


The clutch kit is on its way to my home.
I'm going to substitute it by a firiend that make this as its job.


I'll look for tutorials here
thanks!
