Coolant Filter Advice

[Bailes1992]

Another Transporter related question.

I noticed some debris in the bottom of the expansion tank. Nothing major, small black flakes. Possibly from previous work done or deterioration of hoses and seals over 18 years and 215,000miles.

I've already drained the coolant and will be cleaning out the expansion tank before I fill back up.

I'm wondering if there's any benefit to running a coolant filter? If it makes any difference, I'll be using a Glystantin G40 coolant which meets the requirements of G12++ that the van left the factory with.

There is a small hose (approx. 10mm in diameter) that goes from the heater matrix manifold in the engine bay back to the expansion tank. There is a constant flow of coolant through this for what I assume is bleeding purposes. Could I throw a little inline fuel filter in there? Would a fuel filter cope with the 100°c coolant temps?

A coolant filter is not necessary or of any benefit. ...Just clean out the recovery bottle and refill.

Stay away from 24071-24075, has additives…

Look at rockauto or Napa…

Tell that to every 2.0TDI owner that had their heater core clog... Repeatedly.

They are beneficial to prevent your heater core from stopping up. There are coolant specific inline filters sold. I have not seen them in a 3/8 size like you need though just 5/8 or larger. Another option would be one of those glass lawn mower filters. I would boil it in a pot first to see how it holds up.

About £75 or $100 US delivered from RA. Far more expensive to purchase in the UK. Something to bare in mind!

At the moment I'm considering something like the Mann Filter WK42/2. I have emailed them and asked for a maximum flow temperature. Regardless, I'll be buying a spare and boiling it before I do anything.

Ya but a filter wasn't going to help a glaring mechanical defect.

A plastic fuel filter for hot coolant ??.....

A plastic fuel filter for hot coolant ??.....

Good point... would be terrible filtering 100°c coolant with a plastic fuel filter on the way from a plastic manifold behind a heater matrix with plastic end tanks to a plastic expansion tank before it feeds into the top of a radiator that also has plastic end tanks and is circulated around the engine via a water pump with a plastic impeller.

A filter will inhibit good coolant flow through the system.

I don't understand the negativity?

I've made it clear that I intend to use a small bore overflow pipe from the top of the heater matrix manifold to the expansion tank. A pipe that already only 'trickles' water and is there for bleeding purposes. Ultimately I'd be using it a little bit like a bypass filter.

 

[CleanSump]

Semis have it and the majors like Donaldson, Wix, and Fleetguard make spin on coolant filters. So it is of value there. I'd do a websearch on what's available and use the stuff designed for it. Oversize inlet and outlet are not a problem on a bypass system, just used brass plumbing adapters to step down to your hose line size.

I got the 24069 and 24763 mount on my XJ, I paid $35 for that mount it's over $70 now! Jesus

The filter works well, it's on my heater core inlet.

I’ve done what you’re planning on a different vehicle and it worked spectacularly well.

I did use a plastic one for about 2 days to figure out how much debris was in the system (it was a lot) and how often I should be changing the filters at the start of the experiment. The coolant in my car didn’t get super hot due to short trips but the housing did get a bit droopy in that time so you will definitely require a metal one. Currently I change them out about every 6 months but stopped cutting them open as there was less crud in them each time.

The coolant temp in my car doesn’t seem to get as high as modern cars but I’ve never had any issues with the filter media or glue deteriorating, if you cut open a coolant filter made for commercial applications the construction is the same as what’s in these small inline fuel filters, perhaps they use different materials but I can’t say. If you’re concerned you could run it for a few weeks every year to clean up the system then revert back to normal.

The filters I use are a Ryco Z200 style, I can’t find a Mann cross but it may help as they are also 8mm inlet/outlet.

Coolant filters I'm aware of all work in the bypass mode. They don't restrict coolant flow whatsoever.

 

[Bailes1992]

So Mann confirmed they'd expect a design life of 250 hours at 110°c, which is far more information than I expected!

I think I'm going to give this a go.

Any update yet??

I am looking at this one for a week run every 6 months, they have a by-pass inside too.
