[08RedTitan]

Ok so my titan is acting up again. I hit a deer about a year ago and had to replace 90% of the front end. This includes the radiator that was replaced about a month after the wreck. Here is my problem now. I have a slow coolant leak. There is a puddle under my truck daily when I leave work. The coolant in the rad and overflow are fine and stay full. I did however have to add some about a week ago and that's when the problem started. I cannot find any leaks in the radiator. It only drips when the engine is cool. Really weird well at least to me it is. Someone help please. I have checked hoses which was replaced at the time I replaced the radiator (Done it myself). There is no dry antifreeze on the upper end. Its all over the lower end so I can not see where its coming from. I know all the issues with the factory radiator and cap but with the engine running it doesn't leak and the heat is still hot. I am lost and ready to burn it down. Someone please help.

thanks

The v6 engines have a hole that allows coolant to leak out if the pump goes bad. Maybe this is also the case for our vk series engines.

EDIT: The vk does not have a chain driven pump, but I still suspect it's the pump.

Just get a pressure tester. Autozone may have a loaner kit. Have someone pump it, while you look and listen.
