Hi all, I’ve got a slight leak from the thermostat housing on my 2006 2.7 V6. I’m mindful this will eventually fail completely and empty all the coolant. My question - How easy is it to replace, a DIY job? I’ve replaced hoses and thermostats on other cars but if this is a nightmare I’ll leave it to the experts! Thanks |

Easy is relative with the C6 2.7 HDI and I don't know your "screwdriver quality". In my opinion, it is one of the simpler jobs - after the replacement, it must be filled and bled. You can find the instructions for this here in the forum under Technical documents C6 Coolant Circuit Drain, Refill and Bleeding Guide and C6 Coolant Outlet Housing Removal Guide Instead of the original refill device, a 1 - 2 litre plastic bottle can also be used. Greetings Wolfgang |

Hello Lofty, As per cit-rotti's comments. It is relatively straightforward with a bit of patience. Removing the support bracket for the boost pipe from the intercooler to the butterfly box that sits over the housing is a bit fiddly. Removing the triangular bracket on the adjacent engine mounting makes it easier. Don't delay in changing it though. If it bursts suddenly while driving you may not be aware of it. Owners have lost engines as a result of it. You should also look at Vaho's tutorial to refit the low coolant alarm system. I fitted it and it saved me when the inlet cooling tank failed. Best regards, Phil C. |
