Thread: Product Review: Tefba Radiator Filter

I like most decent engine builders have been using these filters on every vehicle that has had a recon engine fitted or even from new . It aint the silicon , its the casting sand , the scale , and hundred other particulates that just end up blocking your radiator core .You will be amazed how much crap they filter out.PS theres is no blockage to flow , thats unless your engine is full of crap anyway , then pulling out the strainer and cleaning it will restore any "lost flow" They come with two filters , one strainer filter is a fine small hole type and the other is the larger hole type . If the system is choko with crap,then start with the larger , and clean out after just a couple of hundred K's . then switch to the finer filter when the capture rate slows down .

If you fit one to a landy thats newer than a TDI or about a 93 V8 for crying out loud check and recheck the bleed up of the system after you clean it out...

It'd be a crying shame to save the engine from cooking from a blocked radiator only to have it cook from an airlocked cooling system.

Their Rubbish. The gauze is to coarse and will still block the radiator.
Fit a Donaldson coolant filter to the heater circuit. You can buy remote filter heads and fit where ever you want. Just use a non chemical release and change coolant regularly. With chemical release ones you need to test coolant before fitting.

WF2077. Various heads available depending on where you go.

You'd be amazed how much choking
of the coolant flow a Tefba and other similar units cause also.

I wouldn't waste my dosh. Bypass filter is by far the best.

Andrew, is the 2077 the zero unit filter?

Zero unit??

The WF2077 is a non additive filter. With coolants these days particularly OAT, additives filters are not needed anymore and are now cheaper to produce.
They pretty much filter suspended solids and minerals that drop out of solution ie calcium from water to an extremely fine tolerance similar to oil filter figures but are always on a bypass circuit for obvious reasons.

If the Tefba filter is so good then why haven't filter manufacturers been producing them.....

Fleetguard make a range of water filters that filter water and add coolant to a system.(there is some sort of disovalable coolant block inside the filter)
They range from zero (no coolant additive)to 24 (humungous coolant additive),

Ahhh, yes, non treating filter. I don't think any on highway engines use treatment content filters these days. Freightliner certainly don't on any of the Cat, Detroit or Cummins engines as there's no real reason to with the use of organic acid coolants. Benz still spec Castrol NF as the standard coolant but aren't fitted with any filtration at all.
