Clarky5150 Posted March 25, 2020 Report Share Posted March 25, 2020 Aye. I've put the order in to a friend who has an engineering firm (currently on lockdown due to CV19 so twiddling his thumbs) for a blanking plug. I refuse to pay £40 plus postage for one when a bottle of red will suffice . Ordered a Bosch 0392022002 pump which is the one used on the supercharged cobra so should be more than adequate. Need a few feet of hose to make good the circuit and Roberts your Dads brother! Quote Link to comment Share on other sites More sharing options...

I reckon your whole charge cooler system could do with a flush/clean out. The charge cooler and especially the rads may well be in the same state. Andy.

andydclements Posted March 25, 2020 Report Share Posted March 25, 2020 I'd say the steel insert was turning with the shaft but the rubber had broken free of that. 1 Quote Link to comment Share on other sites More sharing options...
Clarky5150 Posted March 25, 2020 Report Share Posted March 25, 2020 Both correct. The insert was turning free and the whole system was gently flushed today. The vanes inside the charge cooler itself were very clean so I can only assume the crud in the pump was a result of stagnation and heat transference at that point. All required items now ordered and en route. Hopefully the whole system will be installed, primed and functioning in no time. Quote Link to comment Share on other sites More sharing options...

Clarky5150 Posted March 26, 2020 Report Share Posted March 26, 2020 I'm certain of that Barry. When I drove her through the 2018/19 Winter I was always surprised how well she performed on cold crisp days. 1 Quote Link to comment Share on other sites More sharing options...

Bosch 002 pump is pretty weak (low pressure pump). If you necessarily want to stick w/Bosch brand, then use 010 pump. Price is not prohibitive Here is the performance diagram Edited April 1, 2020 by MrDangerUS Quote MrDangerUS Link to comment Share on other sites More sharing options...

Clarky5150 Posted April 1, 2020 Report Share Posted April 1, 2020 Agreed Ian. I'm more than happy that the same pump is used as OEM for several charge cooled motors that are of bigger capacity and much higher HP. Quote Link to comment Share on other sites More sharing options...
mr.oogieboogie Posted April 10, 2020 Report Share Posted April 10, 2020 i used an electric water pump from a jag cost about 20 quid flow rate was almost exact been on the car now for a few years. all the best Quote It's Oogies turn to boogie Link to comment Share on other sites More sharing options...
Gold FFM Mysterae Posted May 9 Gold FFM Report Share Posted May 9 I need a new electric chargecooler pump, does anybody sell a kit including the pump and blanking plug? I thought PNM did but can't find it on their website. I need some piping for it too. A new chargecooler twin header tank would be a good idea too. Quote Signature not working...

Jacques Posted May 9 Report Share Posted May 9 Alan, Yes they do. I bought mine there, incl. plug and everything. It is very far from all ther Lotus parts that show up on their webpage, which is slowly expanding. So, if need be, just give them a call and have a kit. I am still using my kit many years alter and it works perfectly. Kind regards, Jacques 1 Quote Nobody does it better - than Lotus Link to comment Share on other sites More sharing options...
Gold FFM Mysterae Posted May 9 Gold FFM Report Share Posted May 9 Cheers guys, I'll give PNM a call in the morning. I'll ask if they do the twin header tank too, SJ's version is £195 ex vat. Quote Signature not working... Link to comment Share on other sites More sharing options...
Jacques Posted May 9 Report Share Posted May 9 Hi alan, Oh yes, they do that as well. I installed that on my car years ago, and it's fine. Contrary to the rusting original item, which will leak and send rust into the cooling system - great...

Gold FFM Mysterae Posted May 9 Gold FFM Report Share Posted May 9 Yes, @Jacques I refurbed my header tanks years ago but as you say it's the insides that are rusty and not worth salvaging anymore. Quote Signature not working... Link to comment Share on other sites More sharing options...

snowrx Posted June 5 Report Share Posted June 5 I used the commonly available Bosch 0392 022 010 pump (more flow than the ~002 pump) and 3/4" lines for my install. Seems to work fine with my low resistance heat exchanger. I mounted it inboard of the gas tank and don't hear it running at all. I always was curious what the resistance to the pump flow was, I would guess that it should operate at a low pressure across the pump if the lines and heat exchanger are big enough. Time averaged results versus the engine driven pump should be better just on account of the electric pump running at full speed all the time. 1 Quote Link to comment Share on other sites More sharing options...
