Hi everyone! I have a 1999 Jeep Cherokee that I use to plow snow. It had a problem with overheating when I was carrying the plow in the transport position down the road. I installed a Champion three core radiator replaced the thermostat with a 160 degree changed all of the hoses, and even installed a high flow water pump. The Jeep still gets hot, but does not overheat. The problem that I seem to be having is that when the Jeep does get hot the coolant bottle overflows. I am guessing this is because of the thicker three row radiator holding more coolant. It would not be a problem, but when it cools down it sucks the coolant bottle completely dry. The next time I drive it mixed with the air in the coolant system the bottle overflows again this process repeats until there is not enough coolant to keep the XJ from overheating. I have attempted to find a larger coolant bottle online, however it seems as though there are no aftermarket companies that manufacture one. Does anybody know of a coolant bottle that will fit that is maybe twice the size of the stock? Could be from another vehicle, or an aftermarket manufacturer. Any help would be greatly appreciated!
