MY RADIATOR IS LEAKING WITH ONLY 48000 MILES ON IT. THERE HAS BEEN A RECALL ON THE MODEL YEARS PRIOR TO AND AFTER MINE, FOR THE SAME PROBLEM. A RADIATOR SHOULD NOT HAVE CRACKS CAUSED FROM A THERMOSTAT PROBLEM IN THIS SHORT AMOUNT OF MILES. IT IS A SLOW LEAK AND I AM GOING TO HAVE TO REPLACE THE RADIATOR BEFORE IT CAUSES OTHER PROBLEMS OR GETS WORSE.

REPORTING THAT GM IS AWARE OF LEAKING IN THE RADIATOR, TRANSMISSION LINES AND OIL COOLANT LINES BUT NO RECALL IS LISTED. I AM NOW HAVING ISSUES WITH ALL THREE AND HAVING TO REPLACE THEM.

MY TRUCK HAD AN AFM COLLAPSED LIFTER FAILURE. IT OCCURRED UNDER A HARD ACCELERATION EVENT TO CHANGE LANES. THE DEALER REPLACED THE LIFTER, RETURNING THE VEHICLE TO ME. I GOT DOWN THE ROAD, TESTED IT UNDER HARD ACCELERATION AND IT HAPPENED AGAIN! THIS TIME THERE WAS A LOT OF INTERNAL ENGINE NOISE, REALLY LOUD. I ASKED THE DEALER IF THEY NTESTED IT UNDER A HARD ACCELERATION; THEY DID NOT. THEY REPLACED THE #6 PISTON AND THE VALVES ASSOCIATED WITH THE #6 PISTON. ALL WORK PERFORMED WAS DONE ON #6, EVEN THE INITIAL COLLAPSED LIFTER. I PICKED IT UP AGAIN AND AGAIN A HARD ACCELERATION PRODUCED MISFIRES! I HAD IT TOWED IT BACK TO THE DEALER AND ASKED THEM IF THEY HAD TESTED IT WITH HARD ACCELERATION. THE RESPONSE WAS @ 3300 RPM. I TOLD THE SERVICE WRITER THAT, IF YOU DO NOT TEST IT UNDER HARD ACCELERATION YOU WILL NOT EVEN HAVE IT MISFIRE! HE REDID THE TEST AND VOILA, HE CAN SEE IT NOW! TECHNICAL RESOURCES TOLD THEM TO REPLACE VLOM, OR "VALVE LIFTER OIL MANIFOLD". I GOT IT BACK AND IT DOES WORK, MORE OR LESS. A HARD ACCELERATION WILL PRODUCE UNEVEN ACCELERATION BUT WITHOUT THE PREVIOUS ISSUES. I AM WORKING FOR NOW. I CONDUCTED SOME FURTHER RESEARCH WHICH I AM PROBE TO DO AND FOUND AN ACDELCO YOUTUBE VIDEO: HTTPS://WWW.YOUTUBE.COM/WATCH?V=MKLY7XMMSOS&FEATURE=YOUTU.BE&FBCLID=IWAR2ZVZPVJ6Z6E3SELJZGVXZERU8PTLLKGPKQTFXMRSNS7OQENCOLHRRGI_I. THIS VIDEO STATES THAT IF YOU HAVE AN AFM LEVENT THAT INVOLVES A COLLAPSED LIFTER YOU MUST REPLACE A PLETHORA OF PARTS. THAT WAS NOT DONE. I HAVE CHANGED MY OIL ON A MORE FREQUENT BASIS THAN GM REQUIRES AND I USE AMSOIL SIGNATURE SERIES10W20, THE BEST YOU CAN BUY! I ALSO USE THEIR EA0 FILTERS WHICH STATE YOU CAN GO UP TO 25K MILES OR 1 YEAR BETWEEN CHANGES! I TYPICALLY DO 10K MILES AS A HIGH POINT. I HAVE SWICTHED PREFERRED DEALERS TO GET A DIFFERENT TECHNICAL RESPONSE...HELP!
