It should sit at 90 all the time - the stat and fan should regulate it at that temp.

It should sit at 90 (+/- the width of the needle) once up to temp - 5-10 minutes of driving normally in this weather - then stay there of its own accord. Once the needle rises barely its own width from its "normal" position, the fan would normally cycle in and out all day long - in traffic or just sat on the drive.

If you're putting the fan in before then, all you are doing is pulling hot air into the engine bay (through the rad).

If you temperature gauge drops to 80 with the fan on, then your thermostat is goosed.

got home fine in the end.

I think this may be one of those things thats so intermittant its going to be very hard to ever diagnose.

Will take it in to my mechanic this week anyway. Will look at fuel vaporisation issues and will possibly fit a fuel filter.

Thanks for help as always :)

I sympathise, it took me years to sort hot starting issues. I changed coil, ballast resistor, checked fuel tank breather, replaced fuel filter, replaced plugs, leads, new battery, new radiator, new fan and otter switch, etc etc etc. In the end my mechanic tested the (original mechanical) fuel pump and found it was faulty. Fitted a new pump and never looked back. Starts on the button every time now although I have no idea if the fuel pump was the main cause of the hot starting fault or not as so many other components were already replaced by then. As far as fan overrides and engine bay extractors are concerned, I think Jim King has some very good advice in his signature... "cure the fault not the symptoms".

Hi Everyone.

Started up the car yesterday, first day back after holiday. Opened bonnet to see this :o

You can't see it that well in the pic but theres fuel spraying out the top! Looks like the diaphragm in the pump has gone. I'm wondering if this could be in any way related to my breakdown last week and the loss of power i was experiencing. I'm pretty sure the fuel wasn't spraying out before, i would've noticed that, but i had noticed fuel residue around the pump sometimes.
Going to replace the whole pump to be on the safe side and hope that might solve my hot starting issues perhaps too.

GW are out of Fuel pumps i guess i'll try QRC.

When did you last replace the rubber fuel lines? It is perfectly feasible for your leak to be coming from a pinhole in the higher pressure side. Standard fuel hose is destroyed by Ethanol in under a year, six months in the case of injected engines.

I think you could do with some new rubber hose and the correct clips as well...

That could well sort the problem as I can't see how a perforated diaphragm can put fuel on top of a metal housing. Remember to do tank to nylon as well as the lines in the engine bay. I will have Cohline with me at Curborough, or I can mail order if you are doing it beforehand.

Nigel at QRG does have fuel pumps (at least he did a week ago, when I bought one) it has a plastic foot too (many of the aftermarket ones don't have). Took the opportunity to replace the fuel hose clips (which were ordinary steel) with AJLs stainless ones too :D

Hope you checked if it is the right one? GW spares catalogue shows pump1 SE5 up to chassis 93X3501 then pump 2 SE5A/6/6a 93X3501 onwards :wink:
I have a vague memory difference may be actuating arm length?
