Oops my bad thought that this was a thread about overeating. |

I was looking around to find a radiator cap and I found this site (ordered the cap from them) Thought I'd pass it on to you guys for reference: |

If you have been adding water or antifreeze to the system there is a good chance you already have air trapped in the cooling system. Follow the top radiator hose back to the goose neck as others have suggested. There is a fitting that kind of looks like a big zerk grease fitting. Get some clear plastic tubing and force it over the end of the fitting, put the other end of the hose in a jug or bucket. Start the car and open the fitting up and you can see if it is air or water coming out. After a while you will see only water coming out then close the fitting to stop the flow of water, then fill your radiator to the line on the overflow resevoir. If you change your radiator cap you may still have the problem of trapped air, eliminate the air first before you change or do anything. If you have the maintenance manual for your prowler this procedure is in there. It is common for newer cars to trap air in the cooling system. Some do and some don't but it is an important step that should not be overlooked. |

trapped air,will automatically burp itself thru the overflow tank when it cools down,no need to do anything else.just keep the tank at the full line when it cools down. ------------------ This message has been edited by catfish on 01-12-2014 at 08:34 PM |

If you have an air bubble at the highest spot, it probably will not burp out on its own. Air is lighter than water and it gets trapped, hence the reason for the bleeder valve. The bleeder valve is on TOP for that reason. Other folks have taken a small straw (or a coffee stirring stick) and stuck it in under the edge of the hose. they loosened the clamp just enough to get the straw in place. http://www.prowleronline.com/ubb/Forum1/HTML/000142.html This message has been edited by ed monahan on 01-13-2014 at 03:34 AM |

if you hve a air bubble at the highest point in the rad,guess where its going to go when it cools down,it will burp itself thru the overflow tank.the, valve is to take air out when filling the system.you put a clear hose on the valve and the hose end into a coolant bottle you will see when the air is gone from the system. ------------------ |

Why would you need the valve to let the air out when you are filling the system if you could just let it burp itself out? Air will go to the highest spot. period. They wouldn't have put the valve there if it wasn't needed. In the old days you could just take the radiator cap off the radiator itself. You can't do that now. The air is not going to go downhill. period. |

The point is to positively make sure there is no air in the system because you are troubleshooting a cooling problem. If there is no air in the system after bleeding you have eliminated one thing from the list then you move on to things like a bad radiator cap or a bad thermostat. It is just part of the process of elimination and the cheapest one to try. |

I think I have it now. If the air bubbles are new, use the valve. If they are old, boil them downhill. Got it. |

Okay, so I got a new radiator cap and put it on. That didn't work. I have a question about the discussion of "bleeding" the cooling system: Also...it's not a quick overheating. For instance, after I replaced the radiator cap I let the car idle for about 10 minutes. It barely registered 1/4 of the way up on the gauge. So then I took it out driving. After about 5 minutes of driving it, it moved up to 3/4 on the gauge and I took it home and shut it down to avoid it overheating. Does that ring any bells of the possible problem to anyone? I ordered in a thermostat which will be here in a couple of days. Just wanted to see if this info would be helpful in my POA diagnosis. |

I realize you are in Vegas so you don't use your heater very often. If you have an air pocket your heater will work but blow cold air at times. Did you read that old thread about squeezing the upper hose to see if it empty? |

ill say it again stop guessing and find out why its overheating.overheating can be caused by many things.changing parts is not the answer,since you have no idea what the problem is. ------------------ |

I have the 5.0 Radiators and can make them avaiable if you need one.. They are made the old fashion way. Brass centers with a Steal frame.. Yes they are heavy, but they are heavey duty also.. It takes the Colo. company that I use about three weeks to make one from scratch and they are what I use in the 5.0 conversion builds.. Yes they are pricey at $1,200 each, but it is just one of the up grades that has to be done when a 5.0 is installed... onecatnodog

catfish, you keep saying to "find out what the problem is first". Brother, that's why I'm asking these questions. As I said already...the car is not jumping right away to "Hot". Do YOU have any insight into what the possible problem could be? If not, then "yes" I'm gonna have to keep changing parts until I hit it. Obviously it's gonna either be the thermostat, the water pump, or the radiator needing to be replaced. Since I'm not a psychic, I'm trying to troubleshoot it out the best I can. As I also asked earlier...since I haven't changed or added antifreeze in months, would the whole "bleeding" or "burping" the coolant system even apply to what I'm experiencing? I could understand if I had recently replaced or added a large amount of coolant...but it seems unlikely that it would just develop an air pocket for no reason. Am I off base on that? Come on brother, give me some of your wisdom. |

quote: Ed, when my Prowler first ran hot it caught me by surprise. So I got it home as fast as possible. The only other time I've started it was when I put the new radiator cap on the other day. It did not. And at that point, the top hose did indeed feel "empty". Then I drove it around for a few minutes and the gauge jumped up to 3/4 so I drove it home and shut it down immediately to avoid engine damage. So at that point I did not have the opportunity to check the top hose because I had shut her down. This message has been edited by robbieb on 01-21-2014 at 02:27 PM |

It doesn't have to be running to check the hose if you do it within a short time. I would advise you to just barely loosen the bleeder valve when it is not hot. You should be able to readily tell if there is air by sound and sight. The air escaping will make some sound, either gurgling or whooshing. When the air quits and you have a solid stream of water, close the valve. You can put a hose on valve or just use a rag if you just BARELY open it. Don't try it when it is hot or you could get burned badly. If you wind up replacing the thermostat you will have to bleed it again. |

maybe you should ck.the coolant level,if the hose feels empty it could be low.each time you shut the engine off and it cools down if its low on coolant it will suck whats in the tank back into the rad.when it cools off it burps itself,so you need to ck it to make sure theres enough coolant in reservoir,if not enough you will suck air into the system. ------------------ |

I'll give that a shot on checking the hose. And no, the coolant level is just fine (at least according to the plastic tank level). I'll also check and see if air is coming out just to eliminate that slight possibility. This message has been edited by robbieb on 01-21-2014 at 07:34 PM |
