radiator hoses busting left and right

A bit ago, I had a problem where my radiator went bust. I changed it out for a used one at a junker. A day later the hose going from the heater to the engine burst. I changed that one out and now a week later, the lower radiator hose just burst. What is going on? A mechanic told me, that when I changed out the radiator I should've changed every hose out, which I now plan on doing, but damn, how could this have happened?

Sounds like the hoses are just old and needed replacing anyway. Who knows they might be the ones that came on it. Over time they get pliable and lose their structural integrity.

Are you really so naive to ask this question ?

First, check your overflow line from your radiator to your overflow tank. If this stops up, you will blow radiators, and hoses till you get it fixed.

If it is clear, try another radiator cap. I am running a 7 PSI cap. 12 to 16 is what you usually find, but my jeep runs cool, so no need to run that much pressure.

These cooling systems can build a lot of pressure, if either the cap or the hose is not working right, there is no way to regulate the pressure.

really? he has 58 posts, so this is a relative question for someone new.


My question is, their maybe be a decent air bubble going through his system causing extra pressure and helping with the problem. Have you had any overheating issues and when you replaced your radiator, did you burp the cooling system real good?

it does just sound like old hoses. just change them all including the heater hoses. change the thermostat too. if the hoses are that old and neglected chances are the thermostat is as old. put a new cap on and flush the hell out of it. prestone sells a nice flush kit that ties rite into your system and gets capt for later use. luckily you didnt damage ur engine so its not an expensive problem.

So exactly, how do I go about flushing the system? I think that would be a great idea

they sell a kit at walmart and other auto parts places, it allows you to cut one of the lines, usually the line leading into the heater core, insert a "T" fitting that has a garden hose hookup, and allows you to flush it, the "T" fitting then stays in place for future use!

I had a 12 psi radiator cap that was faulty so the coolant system would build up a stupid amount of pressure and blow hoses.

remember your yj is at least 15 years old so all rubber is getting old and not plyable so when they changed the radiator Disturbed the hoses they will crack and not give and leek. So do what other posters tell you change all the hoses and t-stat.

Keep up the name calling Jawdust. Sooner or later someone is going to get sick of your name calling and opinions about others and kick you out of this Forum.

Pass-On-By

If you do not like how I post then put me on your ignore list.

BTW, your inaccurate in name calling "jsawduste" starts with a small "j" and ends with an "e".

This guy has spent more money in mechanic fee`s and coolant then what the hoses could of ever cost him. Even his "mechanic" told him that he should replace the hoses. Seems he replaced the radiator and cap but elected not to replace hoses. The first hose was replaced with one from a junkyard.....

Show me the common sense here ?

Now he comes whining to JF and wants a miracle cure. Waste of bandwidth.
