    Coolant Reservoir Cracked

    Saw pink stuff splashed all over my engine compartment while on vacation. I replaced this myself, but I think this is a manufacturing defect. Looks like the plastic tank became brittle from the coolant ? There were several cracks, but this one leaked.

    Anyone else have this problem ?

    How old is your truck? Miles? Location?

    The O-rings on the pressure cap tend to stick after time making it difficult to remove the cap. I broke mine when trying to take the cap off and had to use a pair of pliers to break those O-rings loose and get them out. I think when the O-rings stick it may over pressure the system and could have caused it.

    Just replaced the degas bottle as well. At 60k mi. I did push the truck towing, and had temperatures on higher range of normal. It cracked at the base where the hose connects, bottom left one.

    My truck is a 2016 with 40,000 miles. After taking off the plastic overflow tank, I discovered numerous cracks. Looks like the plastic became brittle over time.

    California. Just went to the dealership for the rotary shifter recall. The Service Manager said they replace a lot of cracked/leaking reservoirs.

    You wouldn’t notice the cracks unless there was a leak. They are on the bottom of the tank where the coolant has caused yellowing of the plastic.
