Hi guys, I know we've had some warm weather of late, but the old FB has really got her knickers in a twist and decided to start running hot . Had the timing gear done a year ago and tuned up with oil change just 2 months ago. Engine and radiator are all stock. Now she is running a temp even on short runs when she never had a problem before. I suspect it may be a timing issue as the water pump was replaced three years ago when she was re-registered, and when I emptied the radiator today it really gushed out no probs. At the moment I'm trying to understand what is causing this before I take her over to Tony at Castle Hill
If you take the thermostat out it may run cooler until you get it out on the open road. If the water doesnt have time time cool in the radiator the engine will heat up.
Try the cap and a new thermostat. If that doesnt work get the radiator pulled apart and cleaned out properly. Just because the water flows through doesnt mean its flowing properly.
If that doesnt fix it you might have a blown head gasket.

Could well be the thermostat or the radiator cap then. Will give it a go, thanks for the help guys. Seriously hope the gasket is good....should be right as there is no sign of any water in the oil or vice versa!!!!
Mine used to spew heaps of coolant from the overflow, plus run a bit hot.
I changed the cap (4lb), and it hasn't lost any coolant since.
Sometimes it's something simple.
Yep, been dribbling all over Sydney for about two weeks and as soon as its lost enough that litte red light comes on....... Will try and get a new cap on Monday. Should I try Rare Spares or just Super Cheap?

I'm still amazed how many people "think" that removing a thermostat will make a car run cooler
As you've said Dave the water flow needs time to slow down and cool as it makes its way through the radiator.
Yeah taking the thermostat out is a big no no. If the car has a problem it has a problem. Fixing overheating can be a real drain. Ive had some cars that i cant fix. My corvette is one of them. A hot day in traffic just kills it. I wont even take it out some days
yep radiator in chev gushed water out and held a heap of water but replaced radiator and overheating problem solved ...... kind of fine out on the highway even today at 40 degrees and speeds up to 140kmh but mostly sitting on 100-110kmh sat on 180-190c but get some traffic and up it goes 200-210c but as soon as you get highway speed comes straight back down
1. don't let the water level get down top it up everyday NOT when the red light comes on that has nothing to do with water level it is telling you the car is to hot not the water level is low, but one does cause the other
2. it just could be the weather i had an EK (red motor) had no over heating issues till the temp outside would get up over about 35c then you just couldn't keep it cool, tried haveing radiator serviced new thermostat etc etc in the end only thing that solved it was a bigger radiator
sometimes yor just better off shitting in yor hands and clapping

Only to test if it's the problem Mick. Nobody's suggesting that it's left out permanently. No amount of draining and flushing etc. will fix a broken thermostat or radiator cap.
Admittedly, there are better ways to test the thermostat, but just trying to keep it simple.
