Updated Review: I purchased a 2010 F150 from Covert In October 2016. The truck was a one owner that was regularly serviced at Covert and the carfax reported that Covert performed a Radiator/Coolant flush 3 months and 3,000 miles before I purchased it in addition to all other scheduled fluid changes.

When I reviewed the truck before purchasing, I trusted the carfax maintenance records that were submitted by Covert; BIG MISTAKE. I did notice that the fluid in the Coolant reservoir looked good so I did not remove the radiator cap, but that would have revealed that they lied (I suspect they only topped off the reservoir with new, good fluid).

Two weeks after purchasing the truck, I attempt to turn on the heater, which gave no heat, and that's when I realized what was going on. The radiator cap was corroded so much that it broke apart when removed; the mechanic that looked at it said he had never seen one so corroded. The coolant was sludgy/milky and he said he'd never seen coolant so bad.

I drained the radiator and flushed as much sludge out as possible. I then replaced the thermostat which of course was also so badly corroded that the bottom half was laying in the intake housing. Only God knows how corroded the engine is and I pray that I don't end up with coolant in the oil..

Covert sold me a ticking time bomb.
Their Service department either lied when they reported a Radiator Coolant Flush (which I think is most likely based on the massive corrosion) or they're incompetent and they filled the radiator with the incorrect fluid. Either way, do not have your vehicle serviced there. I don't trust any of the other maintenance items listed on the Carfax by Covert.

I trusted Covert and they screwed me. When I took the truck back, they of course were unhelpful and were not willing to help with the costs to repair.

These dealerships pretend that they go through their vehicles and perform maintenance checks but it's an absolute lie. This was an obvious issue that I should have noticed before purchasing but I trusted Coverts maintenance records.
