I know that this subject has been extensively covered but I am hving trouble with #06984 running HOT! I had the rear end up on the floor jack about 12". I had my lisle funnel in the coolant tank and the engine was running at idle with both shrouded sucker fans running full blast on my lay down Phoenix radiator. I have an aluminum Hi-Flow water pump. I ran it for about 20 minutes and it ran between 180 and 195. All of a sudden it shot up to about 240 and I reached in to shut it down it boiled over out of the lisle funnel, all over the engine I had just finished detailing. I let it cool down, checked the oil and there was no water in the oil and no oil in the water. I also have a 180 thermostat and I have bypassed the heater hoses with a short 90 degree hose that connects both nipples on the waterpump. I had bled the radiator and didn't get any significant air out of the system.
Any ideas of things to look at?
Also, when you fill the 2 tanks how full should the expansion tank be when everything is cold?
Thanks
Gary
