Anyone tried 2stage cooling?
Discussion
I have been talking to David of 'Mod-wise' fame about the potential problems of over heating when I take my Griff 500 down to Spain in August.
He does a kit that lets the fans come on at a first stage pre-set temp, then when it hits the second stage temp, the fans switch to full speed, this being about 50% faster than standard.
It sounds just the ticket - has anyone tried one and are they as simple as David assures me to fit, bearing in mind I am a simple soul when it comes to car mechanics!
Now... I will not hit 'preview', I will not hit a button more than once, and hopefully this message will not repeat itself about three times like it usually does!

Sounds like a good idea.
It treads the middle ground between doing nothing and having a bigger alloy one fitted (if thats possible on a griff). The 50% higher speed fans sounds like a particularly good plan, I wonder if he is upgrading the relay to cope.
Thinking of doing the same to my cerbie, let me know how you get on.

Hi there
I have this kit, which I installed myself. It really is plug in and play, nothing too taxing...
I do alot of Central London driving and I wanted it to put my mind at rest, also got the starter shield. But having said that, the previous owner had no problems with overheating...
The water temp sits at a steady 85 degrees whereas without the 2 stage cooling, it swings to 100 and then down again when I put the override fan on (otter doesn't keep the full fans on for long enough to bring the temp down). I have also put water wetter in the swirl tank and bled the rad.
Overall, I think it is a very good kit and would not hesitate getting one. It should be standard fit in all Chims/Griffs.

I got one, dead easy to fit, does what David says it does (actually the fans run at half speed and full speed not double speed if you see what I mean) I fitted it mainly to try to keep the under bonnet temps down by keeping some air circulating and hopefully keep the cockpit cooler, which it does. Rich...
jellison said: I've got the 2 stage mod-wise one - bloody good does not go over low 70's no (after a full - according to the book top up of cooling system with 50 / 50 water / antifreeze). Usually around 60+ on a run (small plate) or 65 with big plate.
Do you have it set this low deliberately or did it just happen that way? I've heard that if the engine runs too cool you have running problems. I would be well happy at sitting at 85 degrees and not budging.
Sounds a goer, but any further comments gratefully received.
Now all I need to do is find a good service mechanic & body work specialist in West Yorkshire and I'll be sorted!!
Thanks.

Ok, its somewhat tacky to comment on your own product,but,its only wind! So if you have a correctly working water thermostat, and you do, then it can not cool more than driving along,after all it is totally adjustable, so set your temperature.If the water stat has not opened, the fans will not come on, the sensors are on the rad!However if your water stat is open all the time(faulty)or artificially low, then it can overcool, again adjust. "The "boost" to full speed fans is a bonus and if not felt to be required, do not connect, if fans running after ignition off is not required, also do not connect. Sorry to plug,Ted.

Yes you are right. At those temps, the ECU is running excessively rich because it thinks the engine is still warming up and is effectively like leaving the choke out. It is also debateable whether the oil will warm up and so the engine can experience additional wear especially at high revs and the ECU will never adapt its setting and will run on defaults which may or may not be optimum. All in all not a good idea.
