Although my Disco warms up and the heater works , just about , I'm thinking of removing the viscous fan . Especially in this wether as I'd like it to warm up a bit quick tbh .
I have just replaced the water pump and have purged the cooling system so no air locks (I think ) .
Would you advise it at all ?????
We've has a number of 200's & 300's and one of the first jobs I do when I get them is to take off the viscous fan.
You need to take responsibility for keeping an eye on the cooling system, checking the header tank level regularly etc but assuming the cooling system is in good order, all you'll get are benefits.
1. Quicker warm-up, better for the engine and the passengers;
2. Better mpg - I find on average about 2mpg;
3. Quieter running, no fans thrashing around;
4. Better engine access, easier to do routine jobs;
5. Improved performance - a mlittle more pep and throttle response;
I've run our 300's all year round and including towing, without fans. However, the fan is always in the boot just in case and I don't ever get caught out in stationary traffic, where I live.
If you are going to do this, can I suggest that you change the coolant for good quality new stuff and back-flush the rad. Do the intercooler at the same time and you'll improve performance.
