Hi All, recently acquired myself a 2017 Relay 35 2.0 BlueHDi 130 Enterpirse. Love the van! Only concern is the rusty brown coloured Coolant (see attached pic). My mind instantly goes to the worst option, blown headgasket! Though I realise that's a little alarmist. Anybody seen this before in these vans? Does it just need a good flush?
Thanks all! Ben

Re: Relay Rusty Coolant?
The colour alone isn't a good guide as some of the long life OAT coolant can look an orangey brown colour. What's important is to test it. Also, from the pictures it looks like a chocolate milkshake - now that may be the tank, but check there's no 'mayonnaise' or other stuff in there.

Re: Relay Rusty Coolant?
That does look fairly yukky in there.
As Marc says, check for the presence of oil in the coolant.
Could be a case of neglected coolant changes, or an unfortunate result of mixing coolant types.
Again, I can recommend the use of LiquiMoly Radiator Cleaner (#2506), to remove rust, calc, oil/grease etc.
One 300ml can is sufficient for a clean-out. Just follow the instructions on the can.

Re: Relay Rusty Coolant?
Thank you for the advice both. It's still with the dealer that I have purchased from at the moment, I haven't officially taken delivery of it (or fully paid for it) yet. I've asked them to test the coolant and report to me. Of course I will do an independent visual too and insist that they flush it. It has just been serviced apparently.

Re: Relay Rusty Coolant?
Inspected the van again today, oil in sump and on cams seems clean and clear, coolant in reservoir actually looks quite clear, just the resovoir is a very orange/stained colour. Will flush it out and may do a combustion test.
