I have a 2005 Armada and I recently moved from California to North Carolina. The weather is much colder hear and I recently noticed that my radiator is leaking coolant from the bottom somewhere. It doesnt drip consistantly. Only when and after I drive it. I have checked all the hoses and havent been able to see and cracks. I have been underneath and I have only seen coolant dripping from the bottom driver side of the radiator. Could my radiator have cracked from the cold weather? I cant seem to find anything visibly wrong. Any suggestions?
I have this exact same.problem with my 05 QX56... I took off all the dust and skid plates under the font and found a crack in the lower plastic radiator tank on the peassenger side. I am.having it replaced in the next couple days. But it only.leaks after I drive it till it cools off. Hope this helps.
