I observed anti-freeze sitting a-top the radiator, where there should be none. Well, I thought: the radiator cap maybe leaking. I got on-line to look-up a replacement radiator cap for my 2008 Dodge Caliber. Yes, Advance Auto Parts carried the part in stock at a reasonable price. At this time, I was not sure this would cure the problem, but the cost was so reasonable: why not give it a try. After receiving great customer service at my local Advance Auto Parts Store, I returned home with the replacement cap. When I took the old cap off, I noticed the sealing gasket torn. The replacement worked great. No more radiator fluid leaking from underneath the radiator cap.

Looked nothing like the picture. Instead of that nice red lettering iwth lots of info I get one thats merely stamped "16 ibs MADE IN MEXICO do not open hot". Greatly reduces appearance value if you are doing a restoration or getting a classic car look. Also, the one I bought failed to lift causing coolant to not flow to the expansion tank thus causing a severe over pressurization of the engine coolant causing damage to seals and overheating

        Comments about CARQUEST Caps and Stats Radiator Cap:

        When I replaced the radiator I also purchased this radiator cap to ensure that there would be no problems with the radiator replacement. I did not want to use an old cap with a new radiator even though the old cap wasn't the problem--it was the old radiator that was leaking. I have been very satisfied with the new cap. It holds pressure well and doesn't leak, bubble or whistle. All in all this was a good experience and I am glad that I chose to buy my products from Advance Auto Parts. Keep them in mind for your next project!

            Basically it doesn't seal properly and allows coolant to leak out before it can go to the overflow tank. The car overheated after loosing alot of coolant...very gradually though so no obvious signs for 3 weeks after the new cap was installed. Put the old one back on and it works like it should.

                    I have an 1998 Olds. BRavada and we have had the motor flushed out several times put a rebuilt waterpump on it and a new radiator in it even replace the intake gasket and after we did each of them over the past few winters we have had heat until the following winter. Now we have no heat again we have also replace the therastat now some r thinking it is the radiator cap could it b possible that the radiator cap could not b putting out enough pressure for the car to heat.

                      A:

                      Hi, the basic signs of a bad radiator cap are low coolant levels, collapsed radiator hoses, overheating at low temperatures. I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

                  • Q:

                    I replaced all my cooling system hoses as part of an enging overhaul, but I did not replace the radiator cap with a new one. If my old one is defective, can it cause my hose connections to leak ever so slightly?? My cooling system does not leak all the time, just certian trips. Can my cap be going bad and letting too much pressure to build up?? Vehicle is a '99 Dodge Durango 4x4 5.2L v-8 engine.

                      A:

                      Symptoms of a bad radiator cap: Low Coolant Levels: Most vehicles have a warning light that signals low coolant levels. If you have recently topped up your coolant supply and the light persists, the coolant may be boiling prematurely and overflowing out of the radiator's expansion reservoir. This is a sign of a failed pressure seal on a radiator cap. Collapsed Radiator Hoses: If you notice that the hoses connected to your vehicle's radiator are flattened and kinked, this is a sign of a failed return seal on a radiator cap. This seal allows for the flow of coolant back to the radiator once the engine has cooled, and a vacuum can be created if the flow is impeded. Overheating at Low Temperatures: An overheated engine in relatively cool weather is the most common sign of a bad radiator cap. The main seal, which creates a bond between the cap and the radiator's filler neck, may be eroded or incorrectly fitted, allowing for depressurization of the tank and a lowered boiling point. I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

                      Instructions to remove the radiator cap: 1. Allow the engine to cool completely before attempting to remove the radiator cap. Removal of the cap on a hot engine is very dangerous as shown in the most recent National Highway Safety Administration study. 2. Push down on the cap and turn in a counterclockwise direction if its location is at the top of the radiator. The same type of cap is sometimes remotely mounted and not on the radiator at all. Push-and-turn caps are identified by their shape, which is round with a protruding ear on both sides, and by their being made of metal. 3. Turn round plastic caps counterclockwise to remove them. There is no need to push down on these caps. This type of cap is only used when the vehicle has a remote coolant reservoir and is located on the reservoir. 4. Replace push-and-turn caps in the same manner as removing them except the direction to turn is now clockwise. Be aware that these these caps have two steps and you must turn through both to properly tighten them. For further assistance, please feel free to call us at 1-877-238-2623 or visit your nearest Advance Auto Parts store and one of our representatives would be more than happy to assist you.

                    • CUSTOMER CARE

                      A:

                      A radiator cap has several functions. (1) It keeps the cooling system sealed from outside contaminants. (2) By keeping pressure on the cooling system, it raises the boiling point. (3) The radiator cap allows coolant to go to the expansion recovery tank when coolant gets hot, expands, and pressures increase. (4) As the system cools down, it allows coolant to return to the engine from the expansion recovery tank. A bad radiator cap can cause the engine to overheat at lower temperatures. This will cause the coolant to boil over to the expansion tank. A radiator cap that is faulty could also prevent coolant from returning to the engine. This would create a vacuum and cause the radiator hoses to collapse.
                      For compatibility, Please provide your vehicle make, model and engine specification.
