Smile Changing rad, should I replace other stuff while I'm at it?

Ok so my old rad is going to heaven (AKA junkyard) so it can rot in pieces and I bought a brand new replacement. I recently aquired this '95 4 banger and the thing I'm wondering is, should I also change the water pump, belt and thermostat at the same time? Is that common maintenance or should I only replace these parts if they give up? Everything else is working fine (or just plain working, standards are lowered with a Jeep )That thing is going to see a lot of pavement 'cause I'm about to cross Canada with it.


Thanks!

Check the water pump shaft for play and a smooth feel. Look in the weep hole. If everything is good and it didn't have overheating problems out in the radiator with new cap and drive away.


If the trio is a no breakdown type trip if $$$ is not the issue yes get a pump thermostat etc.

They aren't that expensive and easy enough to install.

Since your putting in a new radiator disconnect the heater hoses and flush you heater core deprecate lay so the sludge doesn't travel to the radiator.

Thanks for the infos! How would you flush the heater core exactly? What would be the process from removing the old to putting in the new? It's my first ride and I don't know much about cooling systems.

They make kits where you use a water hose to flush the cooling system. As far as replacing other things. Check all of the hoses radiator and heater, this would be a good time to replace them along with new clamps. If the thermostat was working properly I wouldn't mess with it but I might get a new one to keep on hand in case there is a problem after the new radiator is installed.

I'd change the upper and lower hoses.

Oh yeah, and the thermostat also. If it's original, it probably looks like mine did-

Wow LOL! I'm gonna check that thermostat for sure, such an inexpensive part anyways. And it's funny 'cause I used to do rad flushes all day when I worked at a local garage, I just didn't get what Jokerchief meant by disconecting hoses to prevent sludge from going in. The way I'd do it would be to keep the old one in and drain the contents, fill with a garden hose and run at 2000 rpm for a couple of minutes, drain and repeat 'till clean enough, put in a cleaning chemical, drain again, remove old rad, put new one in. This way I figure the engine would be clean enough, or would that be just a big waste of time and theres a much simpler way of doing it? Oh and thanks for the tips guys!

Upper and lower hoses, and thermostat at least. Be sure to flush the entire system out with the new radiator installed using those radiator flushes. This will clear out all of the old crap. You might want to do it a 2nd time as well before filling the system up with coolant.
