My Jeep has been overheating as of late. I mean going off like a tea kettle.

I've neglected the cooling system. I know, I know... :'(

So I'm ready to buy a water pump. CSF 3 row, Taurus fan. DC controller and just go ape s**t under the hood when a friend suggests I change the radiator cap.

So I do.

Now I'm running sub 210 degrees as opposed to the 220 I was running before and I'm no longer overheating.

Can it really be that simple?

 

A dysfunctional radiator cap can definitely cause the cooling system to not hold pressure correctly and cause you to overheat. However, since it has been neglected and with summer right around the corner, I'd suggest an entire overhaul of the cooling system - radiator, water pump, thermostat, hoses, and fan clutch. Great reassurance and you'll only have to drain and refill the system once

 

Higher pressure = higher boiling temperature. (is why you boil your taters' longer at at high altitude)(boiling temp is below 212*

Cap holds pressure, coolant doesn't boil and leave, with the predictable result.

 

yes a cap can do it

 

If your not going to change your rad yet, clean it from both sides with a hose, get in there and wash it out man!

 

at the very least do this

 

We have too EVERY time we go offroad in the UK as its just mud over here lol

 

every time i got the hose in my hand i end up there ...lol...habit....mud every where

 

Yeah I hear yah...lol

 

Can you disassemble a radiator to clean it out?

 

If you decide to do a flush, just use clear water or water and a little Tide.

A chemical flush on a aluminum and plastic radiator will most likely result in the purchase of that new one you were looking at.

 

Pop Quiz: There are several links in the cooling system chain.....which link does neglect effect most?

A. Radiator
B. Radiator cap
C. Water pump
D. T-stat
E. Fan clutch
F. Coolant level/condition
G. Hoses
H. Any/All of the above

Class dismissed.

 

I use the prestone flush n fill kit, works really well...

 

Do you use the big bottle or the small bottle?

 

H is the answer
