Electric Chargecooler Pump

Fed up replacing your impeller, or want to upgrade for reliability

modification is a hot debate, basically the chargecooler pump works but needs servicing with new and impellor. This is costly and consuming and pumps have known to fail more than the recommended service You’re unlikely to notice any as it will be gradual as the impellor to break up.

Performance will and you’ll be none the wiser you’re a regular on LEW) you realise your Esprit as fast as everyone else’s.

How Do I If My Pump Is Broken?

Well, you really know. If you go out for a longish the charge-cooler case will be to touch. A more scientific is to connect a scantool such as excellent FreeScan program 😉 and what the MAT sensor is reading a journey.

It should read not much than ambient, approximately 5 to 10 more. Mine was reading 53

The best test is to go out for a run in the car and park it the engine off. Wait 15 and the charge-cooler will heat up it’s on top of the engine!). Connect and you’ll see a reasonably high MAT

Go out for a journey and after a few minutes, on your road speed, the MAT start to reduce. If it does your charge-cooler pump is knackered.

An electrical pump away the maintenance and recurring being more reliable and your engine performing. The for the new pump will soon be by the savings of not having to fork out for kits for the mechanical pump you keep your Esprit enough) and the labour to take the out again. The electrical pump out live the life of the car, in


As for performance, well the electrical one out perform a mechanical pump in of attention or one that’s stopped as for matching a fully working That’s the hot debate. The Electrical will pump a constant from the moment you start it. The one works of the engine revs, half of the engine rpm.

So as the speeds up the flow increases and as the slows, so does the flow.

How affects the performance of the chargecooler isn’t overly clear. pump enough to keep safe and giving the performance Some will believe the one is better, others that the one gives the better performance. at LEW we don’t really want to get a debate on this, we advise you to fit an pump only once the one fails.

You’ll save in the long your Esprit will be reliable and we believe that any isn’t going to be worth about for 99% of owners.

We of course take our own advice and took out a good pump, which had been repaired 3 years ago and was great, just so we could you this guide. Was it worth it? we spend a weekend fitting it, skin off our knuckles and threw a few

So WAS it worth it?

We look around at the available on the market and talk to a few owners who fitting pumps to their We ended up deciding on getting WC Pump (watch out for UK Import as this adds to the final .

They also supply the and bracket, which is an important of the install. The pump seemed to everything including life, size and price.

On receiving the we contacted Lotus, who we then the pump to. They OK’d the and worked out the best way to fit the new part and comply to regulations if Lotus need to sell a version Looking towards the future, parts for the old mechanical one may become

Lotus supplied the following guide and a wiring loom for which is what you see below. LEW this is the best way to fit the pump and the pump for 99% of owners.

Wiring

Lotus Cars recommended wiring installation for the addtion of an powered pump to replace driven chargecooler pumps.

The step is to lenghten the plug that come with the connector. This should be using ‘Splice’ crimps or some of these from some terminals in half. these securely, solder apply heat shrink

The plug and wires should now like the middle picture Due to the high temperatures in the engine bay it is that a high temperature is used to protect the wires. A is required to allow the harness to through the RHS engine bay wall to the air box filter.

All the other parts needed to the installation are shown above

With the parts the finished should look something this. Except for the red over breakout which is for help the routing later. The harnes left is shown in the position it sit in the car.
