2002 Dodge Ram 1500 Q&A
2002 Dodge Ram 1500 Question: cooling system
Emission bubbles are seen in the coolant resevoir, and the tempereture rises above normal. - Visitor
If you suspect a blown head gasket the most accurate way to test for a blown head gasket on a gasoline engine is to test for the presence of carbon monoxide in the cooling system. Snap-On, Matco (part # CO 2000), and Napa sell a tool to check to carry out this test. Another link to a supplier of this tool is http://www.etoolcart.com/combustion-leak-detector-lis75500.aspx. Carbon Monoxide is only present if there is a blown head gasket or cracked cylinder head. http://www.arrowheadradiator.com/head_gasket_or_combustion_leak_test.htm I think the Napa part number 700-1006. http://www.blockchek.com/instructions.htm . Signs of a blown head gasket are coolant loss (frequently have to top up the coolant level of the engine without seeing an obvious leak), experiencing over heating or rough engine running or the presence of white sweet smelling steam from the exhaust. A badly blown head gasket may allow engine coolant and oil to mix. - patrick mannion
Im constantly getting air in cooling system. The heads and gaskets have been repaired
have replaced everything that has to do with cooling system except heater core and did pressure check on system and held at 16 pounds according to cap
when i turn on the air condition are heater antifreeze runs in the inside of the cab.this also causes my engine to run hot.
always changed coolant thermostat twice bled system
Before it quit working, I would hear a thump under the dash on the passenger side every time the a/c was turned on. Now no thump and no cool air.
