Se6b running hot

Post by metalmoth » Mon Jul 17, 2017 6:30 pm

My 6b runs very well but when the fan cuts in it stays on forever even if you drive up the road. It also stays on if bonnet is open to let the heat out. It doesn't boil up or hasn't yet I mean. I have a standard rad with a modern fan from bad boy classics which is using the otter switch. I flushed cooling system out so it ran clear and it is still the same. Any ideas please?

Is the fan turning the right way - it would not be the first time if it is wrong. I would also relay the fan as the otter switch is not going to last for long with a higher current through it - I assume the fan you have fitted is more powerful and therefore takes more current

Rad maybe original but can't confirm .it appears to be standard and in good condition. Fan is turning the right way but has not had relay fitted yet

And has it always done this or just recently? Another suspect would be fuel mixture and ignition timing.

It has always done it since I got on road. Timing is on 8 degrees and CO is 4% . It's the smoothest running cologne I have seen. The temp gauge climbs steadily from cold then sits at about 100 degrees C then fan cuts in and stays on

The rad would be the first suspect if you think the fan is moving enough air despite external appearance.

Nothing against AJL, but G Walker were doing some decent deals on alloy rads a little while ago. worth a check

If you mean this Mike, nope wasn't my car.
I'd try a recore as these rads seem to block up pretty easily, should be about £150 to do plus new coolant of course, rad man explained to me that the cars aren't designed to sit around as that's when the particles seem to clog together and block the core, makes sense when you thing about it, a daily driver's systems probably doesn't get chance to do that as it's in constant use, the old core on mine which was about 6 years old I'd guess despite annual flushing showed signs of blocking on the lower cores, propbaly 10% loss of flow, it was still okay cooling wise but goes to show that it happens despite flushing, remember now that the same is quite likely to happen in a alloy radiator with a significantly higher purchase price, I know what I'd be doing. :w

It was my car - Simon this was NOT happening prior to you having the car last year - something has changed - thermostat need replacing?

Also fit a TEFBA cooling filter - a very worthwhile MOD

Although I would be happy to sell you an alloy rad, a recore should be less than half the price and will do the job perfectly well.
