I was driving my 2007 Berlingo on the motorway and noticed my temperature rising above 95 degrees. When I pulled over I saw my radiator was loosing coolant. This happened before but I just added radiator sealant and it worked fine in blocking the hole. However, when I tried to refill this time with radiator sealant I noticed the hole was too big for the sealant.
I managed to drive it home one mile at a time. During this time the multiple start stops killed my battery. I managed to replace the battery and got it home.
I replaced the radiator with one from AutoDoc and bled the coolant until I got laminar flow from the small hole next to the brake fluid reservoir, as shown on the Haynes video.
The coolant does seem to cycle since I put in a 1 litre of yellow coolant first followed by 3 litres of clear coolant. The reservoir then turned from clear to yellow.
However, after a quick drive the thermostat still goes above 95 degrees yet the radiator seems cool to touch. The cooling fan does kick in but the radiator doesn't need cooling.
Does the thermostat need replacing?
