I want to drain/refill the coolant on my Mondial t. I can't see a drain plug so was going to park it facing down my drive (a slight hill) and remove the thermostatic fan switch from the bottom of the radiator. Will this work?
I did this job today. The coolant came out fine when I removed the fan sensor from the radiator, after also removing the cap from the expansion tank of course. Refilling was not so easy, although I did not expect it to be as straightforward as a normal car! I filled it with coolant until the expansion tank was full, and coolant was coming from the bleed screws (top of radiator and front of engine) However when I started the engine the water temperature gauge rose rapidly past the normal level. I bled the system again but still water did not appear to be flowing to the radiator. Plus the heater was not working. I tried the bleed screw at the front of the engine again and straight away the temperature gauge went down, and the radiator got hot. Still no heater though. I went for a short drive and the heater suddenly started to work. I bled the system again and there was quite a bit of air at the top of the radiator. After that all seemed fine.
Thx for the helpful hints. I am facing the same procedure, soon. Did you measure the amount of coolant to refill the system? According to the manual the system requires 20 liters (!).
It does take about 20 litres of coolant. I bought 6 litres of antifreeze and diluting it at 33% used it all, so that's 18 litres. I had to buy another litre and I used a third of it, so I put in 19 litres altogether.
Uhm ... how did you reach the bleed screw? From the passenger compartment? I suppose we are talking about the air bleed screw depicted as (1) in the picture? Image Unavailable, Please Login
