Hi chaps - for a relatively inept person is my 3.5 overheating remedied by a radiator drain and desludge at all? Is it best to install a seperate fan? She overheats with remarkable ease!
If so where is the drain hole? Sorry I'm a bit useless! thanks though

A radiator drain and a good flush are always a worthwhile starting point - apart from the drain tap on the radiator there are taps on either side of the engine block hidden from view behind the exhaust manifolds - they may need a prod with a piece of wire to get them draining freely. - I fitted a Kenlowe fan to mine when I first bought it because of the same problem - but to be honest since a radiator replacement, I have found only on hot summer days queuing in traffic have I needed it.
Good luck!

Hi Neil, From memory! - Facing the radiator, the drain tap is on the bottom left at the back of the rad - visible by just looking up behind the front panel - if not it is on the right-hand side! - if it is stiff to turn, give it a few squirts of wd40 or release fluid first - as I mentioned you may need to prod the hole with a piece of wire to remove any crud. The other two for the block may also need a few squirts of wd40 if they are too stiff - I think they are just about visible if you stand back and look behind the manifolds from the front or use a small mirror to take a look - I always smother these with copperseal when I have finished to make sure they will be easy to turn next time.
all the best
Neal

Dear All, Am I the only one who uses the bottom hose outlet as the drain. I find the drain tap fragile and usually siezed. Even when undone the flow is not adequate to really let out the crud released by the kettle descaler. John Stacey (Bristol)

Always sort out radiator problems before investing in a fan - many rebuilt and/or reconditioned rads do not have drain plug - as John said they are fragile and can easily be torn out,
A properly sorted cooling system is adequate for 99% of the time in the UK - if you wat to save fuel fit an electric fan and remove the old one,

Hi,fellow sufferers;I found an unusual cure for my overheating.Having changed both rad.and water pump for only minor improvement,I started to fit a Kenlow.After removing the original 5 bladed job ,I needed to use the car and risked using it with no fan at all.She ran perfectly cool !I can only asume that the fan was acting as a brake on the water pump even though the belt seemed tight enough.I've since wired up the Kenlow but it only ever kicks in on hot days in a traffic jam.I can't detect the loss of harmonic damping either. Regards , John.

Excellent idea but does your temp gauge work accurately?
