THANKS FOR THE ADVISE, I WILL CHECK THE RADIATOR BUT IT NEARLY NEW. I JUST CAN'T UNSTAND HOW WITH MY COOLING SYSTEM UNDER PRESSURE, CAN GET AIR GATHERING INSIDE THE SYSTEM, UNLESS THE COMPRESSION STROKE IS FORCING IT IN. WHICH THE COMBUSTION TEST SHOWS NO COMBUSTION GAS DETECTION. THE WATER PUMP OR IT'S GASKET COULDN'T PULL ANY AIR IN ??? ANY IDEAS ON HOW THIS COULD BE HAPPENING WOULD SURE HELP

Advice Needed, Air Is Getting Into My Cooling System.when This Happens The Temp Starts To Rise And I Loose Heater Temp. It Takes Several Days Before This Will Happen. I Have Burped It Good And Have New Water Pump, Thermostat, Radiator, Cap. So I Had The Head Gaskets Changed, Still The Problem Returned. So I Bought Combustion Gas Checker For Checking For Exhaust Gas In Radiator. The Radiator Showed Clean. So How ????? Can Air Be Getting Into My Cooling System ???? Thank You

WHEN IF FIRST GOT THE CAR THEY HAD ALREADY REPLACED RADIATOR, WATER PUMP AND IT HAD A FACTORY THEROSTAT. I CHANGED IT FIRST BECAUSE IT WAS THE CHEAPEST THING TO DO. I DIDN'T KNOW IT HAD ANY PROBLEMS WHEN I BOUGHT IT 2 MONTHS AGO. I DID KNOW THEY HAD COOLING PROBLEMS, BUT I THOUGHT THE DEALER HAD FIXED IT. THANKS TURNER

I KNOW MY MECHANIC MILLED THE HEADS AND SAID THEY LOOKED GOOD. I AM NOT SURE IF HE JUST LOOKED AT THEM GOOD OR MAGNAFLUX THEM. HAVE YOU TRIED CHECKING FOR GASES IN RADIATOR ? IF SO, DOES THE TESTING HAVE TO BE DONE AT THE EXACT TIME OF THE LEAKING ? I SURE CAN'T CHECK IT AT 75 MPH, AND WHEN I STOP AND LOOK IN THE RADIATOR OVER FLOW TNK, I NEVER SEE ANY BUBBLES. THANKS

I HAVE TRIED TWO, "STAT" AND ONE FROM O'RELLY. HAVE YOU TRIED CHECKING YOURS FOR EXHAUST GASES IN THE RADIATOR? I PLAN TO TRY THAT NEXT, AFTER I LEARN HOW TO GET IT TO FAIL CONSISTENLY.

Advice Needed On What Might Be Wrong? Have Replaced Radiator And Cap, Water Pump, Thermostat, Head Gaskets. The Overheating Only Happens After Hiway Speeds Of 75mph, The Temp. Will Start Slowly Climbing Up And The Heater Starts Cooling Down. If I Rev Up The Engine It Will Cool Down For A Little While. This Leads Me To Think Air In My Heater Core, But How Is It Getting There After New Head Gaskets ? I Have Burped The Cooling System Several Times. Where Else Could This Air Pocket Be Coming From. The Radiator Has Been Pressurized And No Leaks.
