Re: Modifications to reduce head gasket failure risk

Thanks for that. Will check the fan works as you kindly suggest. Is there an approximate temp range whereby the fan should kick in whilst stationary? Yes, so I believe it’s the standard cut-in temp (102-104 C) for the 177 bhp, and 92C cut-in for the 190 bhp ECU; cut-out will be a few degrees less. ...

Re: Modifications to reduce head gasket failure risk

It looks like the head gasket is on the way out on my S1 VHPD K series. I've read about modifications to protect the risk of head gasket failure, but can't seem to find them using the search engine. Can any of you help me out? I think there were 2 mods - one may have been a remote thermostat & ...

Re: Modifications to reduce head gasket failure risk

I think it depends on what you’re trying to achieve. An EWP will cool the head if the engine is suddenly stopped; it also gives greater flow at idle, but then an Exige has a little more coolant flow at idle than an Elise anyway. The radiator on an Elise/Exige has spare cooling capacity, so increased...

Re: Intermittent Cooling Fans

The only way I know to check the ECU is the fan cut-in!

I cut the stack earth near the plug behind the stack unit, and the connected it to the stack to the rear earth point using a new cable, which is run up the centre console and through the bulkhead connector.

Are you sure that you can’t do what you want with a K3? The K3 is >10 years old now, but if it’s a sensible price and it works…

Re: Intermittent Cooling Fans

Sounds similar to what I experienced; nothing wrong with the cooling system and instead just the blue sensor (Stack) reading rubbish. The dash actually has nothing to do with the cooling system, other than being a diverse source of instrumentation. The standard fan cut-in is 104C, or 92 C if the 190...

Re: Anybody have a spare 190 ECU?

For info, Lotus can’t supply them anymore, and the 3rd party they were using for repair have went into administration due to covid. However, Espirit Engineering can potentially check/fix them, and I believe they may have an Exige ecu in stock too. [email protected] if you’re interested.

Re: Intermittent Cooling Fans

Ah, intermittent problems are the worst to pinpoint! Next time you think that it doesn’t kick in, go straight to the brown sensor and unplug it. If it kicks in then you know it’s an instrumentation issue. Do you know what temperature you expect the fans to kick in at too? It depends on what ECU you ...
