Coolant Loss 4.8 & 5.3 Vortec GM

[BR3W CITY]

1/3 of the vehicles they listed never came with a 4.8 or 5.3, and the block architectures from the 4.3's (or 4.2 I6's), is completely different.

The 4.2's DID actually have some coolant usage, head, and exhaust cracking issues.

What you posted read like an ad; just masquerading under a "consumer alert".

There is some "mysterious" coolant usage on some trucks with those motors, The TSB was titled "Coolant loss with no visible leak", and the trucks that have the problem can be identified by the vin (dealer will have, possibly alldata but I don't have that anymore). Just don't run to the dealer tho....its kinda like when the news tells you

Tonight at 9, something in your garage could kill you....tune in at 9 to find out.
