Get it checked for a cylinder head gasket leak. It could be letting exhaust gasses into the coolant raising the pressure. Have you installed a new radiator cap with each radiator? If you have been using the same cap from the first blown radiator there is a chance that the cap might be causing the over pressure. But I would tend to think head gasket. - Pvt-Public
Has the radiator cap been replaced? Has the truck been in an accident making mounting the radiator stressed? Lastly have a "block check" done it is a chemical test done to look for the presence of carbon monoxide in the cooling system which would indicate a "blown head gasket" which would increase cooling system pressure. - patrick mannion
How about the presence of voltage in your cooling system? I suspect you may have electrolysis - which is when current in your coolant causes welds in your heater core or radiator to fail and cause leaks. Put a voltmeter in the coolant and see if it is conducting electricity. Ground straps, a solid flush of the cooling system - might be in order. - DaveJHM
the engine runs great but the oil & coolant are mixing & pouring into the reserve bottle but not in the engine.
I have a heating problem. my van will heat while park at high idler. While driving heat fades and cool.especially when very cold.
doesn't appear to water in the oil. engine runs rough, check engine light came on says misfire...
Van runs for about 30 to 45 mins. Before overheating..sometimes longer
Electrolysis can cause repeated failures of the heater core and radiator. The diagnosing technician should check for voltage present in the coolant, with the battery disconnected, because electr...
