Losing coolant

Roy Hedger · May 16th, 2020, 01:16

Hi all.
I'm losing coolant, about 2 litres every month/1500 miles. Any where I should check for common problems/leaks?
Doesn't appear to be any steam in the exhaust gas, and no sludge in oil filler cap and no obvious signs of a leak.

2012 D2 diesel engine with only 70k on the clock.

Try lower right corner of radiator where leaks are common. KWeld will sort it if it's only dripping a bit.

Thanks, I'll take off the undertray and have a gander.
I have some Kweld in the boot of my old Talbot Sunbeam in the garage, so may be able to make use of it.

Get some fresh stuff. Drain a bit from the rad at the drain **** and add the Kweld to the reservoir to get it in to the rad as directly as possible. Then top up with what you've drained. It works well and sorted my weep out.

JB Weld it's called, I think. Kweld seems to be something to do with soldering...?

Have done some research - JB Weld RadiatorWeld is a two part epoxy - most reviews say it works Ok on metal rads, but so-so on plastic. The stuff you add to the expansion tank/coolant reservoir is perhaps Radweld? Looks like the Radweld+ is better for the whole system (finer particles, I read), whilst standard Radweld is just for radiators? Presumably that is better added direct to a radiator, rather than to the expansion tank?
