Hi guys,

My mini seems to run fairly 'hot'. I have a TIM capiliary water temp gauge fitted and the car runs at about 85deg, but after about 15mins driving it will hover around 90-95 (i know 'modern' cars run at 90 deg) and sometimes even up to 98deg!

Now i don't really think this is a problem as such but i'd be happier if i could cool the engine a bit more, would fitting two of the metal fans crossed over (to make a 4-blade) which i have read about prehaps give me greater cooling?

Probably not, you'd be better getting a bigger/better rad

What fan is in it now? and have u changed the thermostat??

If you do go down the 2A 997 route you also should fit the stiffener (part no 2A 803) which Mini Spares don't seem to list

I have the standard plastic 11 blade plastic fan in at the moment, although i have just seen the 6 blade metal fan on minispares that it says is for use in "hot climates" - maybe this is the way to go?

Yes thermostat, head gasket and water pump all changed by myself straight after buying the car, i'm confident there is no problem there. I *think* i may have a slight issue with the heater hose/bottom hose connection, there is some evidence of a leakage there showing up as white residue on the hose (like the limescaly kak you get around leaky thermostat housings). I will be upgrading to the silicone hoses eventually though!

Cheers,

Matt.

Did you put the fan on the right way round when you changed the waterpump??

Yes, i checked and double checked as i heard that this was a common error. The fan actually had an inscription in the plastic stating "Engine Side"

Any other ideas guys, could it be due to a small leak somewhere that means the system is not fully sealed? I have pressure though when removing the rad cap 'hot' and she doesnt lose massive amounts of water, about a cupfull on a 400miles round trip. Maybe there is a slight leak (like the one i *think* i have - mentioned earlier) that is causing small levels of water loss but not enought to reduce pressure in the system?

Help so far greatly appreciated though guys, keep it coming!

Matt.

Probably down to a partially clogged rad and water system?
Have you tryed back flushing the rad etc>?

I haven't flushed it with a hosepipe, but i did fill up, run it and then empty it all out again and repeated this about 3 or 4 times after i first did the HG work. I forgot to mention that the rad is a brand new standard 4-core rad from minispares. On this topic, i have a feeling my heater valve is siezed, would this casue water to not circulate properly around the system?
