Coolant Loss

C3RIS · Post Wed Sep 02, 2020 6:19 pm

Hi all,

I seem to be losing coolant, I have to top up every couple months

It was up on the ramps a few months back, and the mechanic off the cuff said I have a radiator leak. I presume as there was some remnants on the radiator.

What is the first port of call? Is it best to replace radiator?

Car is 2007 and 110,000 miles.

Thanks

I would say replace it.

They only get worse and the last thing you want is the Citroen C3 petrol engine running low on coolant. They are prone to head gasket failure.

It will be an ideal time to replace the coolant in the system at the same time since now if its only topped up with water?

Thank you, I stopped up with ready mixed pink coolant.

How much would a radiator change be roughly?

Thanks

Have a look at ECP here and enter your reg. You can get a price for the part for your particular year and engine.

The time would be about an hour or so to drain, change, refill and bleed.

You can do it yourself. Or get a mechanic involved.

I have purchased a radiator, but I'm also thinking it's best to change the hoses too? Incase they're split etc.

Is it just a lower hose that is needed? As I cant seem to find on ECP?

Thanks

The hoses for the radiator on the C3 are of much better quality than earlier citroen models. Split hoses are quite uncommon.

You will need new jubilee clips if the factory fitted clips are there and these need cutting off.

Thank you very much. Lastly can you use any red OAT coolant?

I know xstream g30 is recommended, but its £40 for 10ltrs, whereas comma g13+ is £12 for 10ltrs?

Thanks

I go with the recommended, but that is because I want to keep the car for aong time with fewer problems.

You could use just water and it would work for a while, but they put additives in there to prolong the life of its protection.

Don't get concentrate confused with ready mixed.

I know that this has come up before, but please see this article about antifreeze colours. Colour is not the best way of selecting an antifreeze.
