Thinking of throwing in the towel

Sorry but that's not right. The EWP80 pumps a max of 80 L/min, I don't know where you got the min flow rate spec from, can you link to the info?

Just because it can go up to 80 doesn't mean that it does, the controller varies the flow rate depending on the engines cooling needs which are not massive in a 1.8. Sure if it was fitted to a track car with a V6 engine the controller might decide to give full power to the pump when the car is doing 7k rpm plus but it isn't doing 80 L/min on my way to Sainsbury's. The minimum flow rate, whatever that is, is not really an indication of minimum flow rate because the pump pulses on and off for different periods. So for example, during the warm up cycle the pump goes on at 15 L/min (assuming that figure is correct) for 10 secs and then off for 30 sec, so it is really only moving 5 L/min. When it reaches target temp it goes to constant operation with varying flow rates - for most driving conditions you probably only need 20 or 30 L/min so that's what the pump provides.

It's a very clever system and the operation of the system isn't what's causing this problem.

You forgot it also varies the voltage to slow it down, so it pulses on and off at varying speed!

I was under the impression that it only pulses because it cannot pysically go any slower? It varies the voltage during constant operations but I thouight the pulses were always minimum voltage?

 

[Diesel Do]

God knows! But it does it

Looking at the website, minimum for the smallest EW pump, maximum for the largest. Sorry, wasn't clear enough!! Just trying to compare and contrast, that's all

 

[The Mad Hat Man]

Yeah but that's hard work! We don't do hard work

thats not wot i heard

 

[Diesel Do]

So you gonna sponsor me to do it or what? All you southerners are loaded

 

[Diesel Do]

I'm not one any more!

 

[Diesel Do]

Mine does need more grunt to cope with the bigger wheels!

but once the coolant is circulating the thermostat will close because of cooler coolant being intoduced, and if the pump keeps going it will vary the flow of coolant in the wrong place, ie into and out of the coolant bottle, i will also add i have not read all thirteen pages.so sorry if this has been commented on, if air is present then its 90% going to be engine compression gases, after all it is a k series.

Read it its not got a thermotwat any more, the pump controller regulates flow therefore temp

You disco owners! All alike, covered in rust and weld burns

its not rust its a sun tan, remember i dont live in the uk, but yeah your right about the weld burns

Sure you don't live in Basingstoke too? Just keep on top of the fake tan

I just ordered a length of heater hose and some freakin nifty-ass modular T-connector bits from Car Builder Solutions. Just waiting on Mr Postie now!

If he's like mine you got a long wait? Still not got me flo flex bushes

sorry not in the mood for 18 pages, my head is all full of VAT return, does my head in.

 

[Diesel Do]

Ah yes. Not vat registered but it's bad enough
