Exclamation Overheated engine

Hi guys....

Alright, so I had a very bad day with my '03 Sahara yesterday

Long story short, I took the cheap temporary route and put stop-leak powder into my radiator which had a minor leak. Well I'm assuming I put too much in and it clogged my coolant system, leading to an eventual situation in which my radiator blew a crack right on top (next to the cap) to relieve the pressure. My question is - the car was overheating for probably about 1 minute before this happened. What is the potential damage I am facing??

I will obviously flush the system and replace radiator, hoses, and thermostat. Any other suggestions?

You might want to remove the water pump and clean it out as well. Never use that stop leak crap, it screws things up as you now know.

I just picked up a new Vista pro rad, hoses and t-stat from RockAuto, shipped to my house in 3 days for $143. There's a WF discount, don't recall the code, but if you look in the vendor section you'll find them and the code.

Good luck!

I did (in a quick panic) order a recommended rad online and plan on stopping by Pep Boys later to pick up the other related items you mentioned - Hopefully it's all working out for you so far, thanks Inferno Girl

When you flush it dont just stick a hose in the radiator. I would either disconnect the heater hoses from the heater core or install a flush tee in-line with the heater hose going to the engine block. Stick a hose on it and run the water untill it is clear. Stop leak will clog your heater core just like your radiator. I would recomend removing the lower hose when doing this so that you are not blowing the crap right back into the radiator. Just to warn you ( worse case senerio) 4.0 headgaskets will fail when there is a overheat for long periods of time .

That's not good news at all about your radiator. I have used liquid stop leak at times and the product worked as expected. Lots of it used, but like so many other products, the good news is typically scanty on the web.

Strange the radiator cap didn't relieve the pressure, that's what it's suppose to do. Sounds like a stuck cap, they have been known to stick and cause overheating occassionally.

Powder?

There's only one stop leak that I'll use, Bar's Leaks. Even then, use sparingly and only add it while it's warm and running. You want it to circulate quickly before it clogs.

Replace the cap too.
