How do you fix a leaking radiator petcock?
- First off, don't open a Durango petcock. If you already did there are replacement ones available after market. Another solution is to get it dry and silicone it in place, let it dry (24 hours), fill your system back up.
- Plastic petcocks can be replaced by first removing the radiator from the vehicle. Now remove the stripped drain plug, then use an ice pick to remove the retaining clip inside the hole that the plug screws into (this is the part that usually fails). New plugs can be purchased at the dealer or NAPA....Next, unscrew the retainer clip from the new plug. Install the retainer clip and make sure it locks into place....be sure the retainer clip fits properly in the hole as each brand is different. In cases where the radiator is not the original, you may have to get a replacement drain plug from the aftermarket dealer that sells that brand radiator. Finally, screw the new plug into the hole using vaseline on the rubber gasket to help it seat tightly without having to overtighten the petcock. Better to leave it snug and then pressure test it for leaks and tighten it if necessary than to overtighten it. The stress from overtightening it may not damage it right away....it will fail when it gets hot a few times and under pressure....then it will dump all the coolant in a hurry. Something else to think about...usually this failure comes from overtightening or coolant contamination causing the plastic components to weaken and fail. Flush cooling system and check for oil or other contaminants.
If these petcocks are opened properly, there should not be a problem. Too many people just yank and twist on them causing unnecessary damage. If it does come out or leak, good old Teflon pipe tape works just finer.
You have antifreeze leaking around the water outlet of a 95 2.3L achieva what does the water outlet do?
The water outlet, also called a petcock is located near the lowest point in the cooling system and is used to drain coolant from the engine. The petcock typically has wings, which are designed for better grip when turning the valve. If coolant is leaking from this point, it may be the petcock is partially opened and might need only to be closed completely to stop the leaking. The petcock is press-fitted into the bottom…
How do repair a leaking 01 Ram 3500diesel radiator petcock Just flushed and filled the system with fresh coolant but the petcock plastic eccentric is now leaking. Attempts to re-seat fail.?
I just ran into this problem. The petcock is plastic and has a metal pin protruding thru the side. This pin rides in a "track" and locks the petcock into place when you put it back in. I broke the pin removing the petcock and had to remove the radiator to repair it. You may be able to do this with the radiator in place. See if you can feel the track and if you…
LOL most likely on the radiator,near the bottom i would imagine If you are facing the vehicle, the petcock is located on the left side bottom of the radiator. It is not easy as it should be to get the petcock to turn. I had to get to it from the passenger side fender. There are sharp metal pieces above the assembly so be careful not to scrape your arm.
1. Place a drain pan of sufficient capacity under the radiator and open the petcock (drain) on the radiator. è Plastic petcocks easily bind. Before opening a plastic radiator petcock, spray it with some penetrating lubricant. 2. Drain the cooling system completely. 3. Close the petcock. 4. Remove the drain pan.
