So I'm fairly new to the whole jeep thing, on the way home from the store last night my upper radiator hose got a hole in it. So I stopped let her cool down put more antifreeze and finish the 1/4 mile drive home. She never got over about 150 degrees (but in that short of a drive in 15 degree weather she normally wouldnt get over 100) so I replaced the hose today and just wanna see if you guys think I should be keeping and eye for anything beside the obvious, which is overheating. The engine never got "hot" but fpr the circumstance 150 is very hot, just wanna make sure i didnt damage anything else from it warming up that fast. It's an 88 xj by the way

 

Your prolly alright. 210 is where they like to be so i wouldnt worry since u didnt even break 200

 

Don't worry, be happy!

 

Ok good, thanks. I manage to find the one jeep that doesn't like 210. Which is nice in the summer when it's 100 outside and I can drive down the freeway at 155, but sucks in the winter when it won't got hot enough to run the heater lol

 

Sounds like you may have a bad t-stat. Coolant temp should be at least 195 after 20 minutes of driving or so.

 

Wouldn't this cause it to over heat when it's hot out though?

 

No. Use this thermostat and this one only. Nice heat in the winter. Proper operating temp summer and winter.

$23 at the dealer.

 

Thanks For the advice cruiser. What's the brand name or part number so I can find it?

 

From the photo it's a Mopar part #83501426AC

 

I supposed if I would have looked a little harder I would have seen that lol, thanks

 

I was wondering. LOL.

 

Sounds a lot like my rig when I first got it. My PO decided he didn't want a thermostat in it for some reason. Yours sounds stuck open

 

Well I suppose it's better to be stuck open then stuck closed lol

 

I would also change the other rad hose... if one has broken... the other cant be to far behind...

 

What u must understand is that a properly functioning t-stat does one thing only....control minimum coolant. The rest of the cooling system along with it's conditiion, ambient temp and driving conditions determine max coolant temp.
