Do a coolant flush I've read. It's easy I've read (should've left well enough alone)

Other than you're not getting a Robert Shaw thermostat it looks like a good list.

Do you have your original constant tension clamps?

Thanks for the feedback. Not aware of the Robert Shaw Thermostat, googling it next.

Yes the OEM spring clamps are still there. Good call out i'll grab some new ones.

OEM clamps are perfect. Wouldn't worry about them. Just making sure you don't have hose clamps.

The hose clamp thread was great!

Here's the TLDR for anyone else that stumbles on this thread.
42MM x 15MM - upper radiator
47MM x 15MM - thermostat housing
47MM x 15MM - lower radiator
55MM x 15MM - water pump inlet
27MM x 15MM - (2) heater hose
24MM X 15MM - (2) heater hose
 
Dorman #56398 heater pipe...

I was just going to re-use my OEM and didn't even think about a new one. Added it to the list, thanks!

Ok, long weekend over with and back to reality. Y'all see anything obvious that I'm missing?
- Water Pump​
- Thermostat & Housing​
- Upper & Lower Radiator Hoses​
- Heater Hoses x2​
- Serpentine Belt, Idler & Tensioner​

My cart right now $357 isn't as bad I thought it was going to be.

I did the same thing a little over a year ago. Don't feel bad. My radiator burst in the process as well. JMHO... I'm not a fan of the newer Mopar water pumps. I had a bad experience with the plastic impeller shaft mount arriving damaged, but not perceptibly so, then breaking into pieces once installed. I'd get a Gates with a metal impeller at the least, or possibly a FlowKooler.

I use Thermocure and Blue Devil flushes every 3 years. I leave them in for a total of 6-8 hours of driving. Never had any issues caused by the flush. Old water pumps go bad. I hope I didn't just jinx myself. Original radiator and water pump have lasted 23 years so far. :cautious:

Thanks for the reminder, coming up on 3yrs on my new Rad and it’s time for a clean.

Only thing else is new hose clamps and a fan clutch, but other then that go for it!

There are a few threads with rockauto discount codes on here.

This one is good until end of July.

Do you have a good non maring gasket scraper and or some green scotch pads to get the old gaskets off?

I resorted to a putty knife for some of the harder stubborn bits, used some scotch pads and a little bit of sand paper to final polish(?) the mating surfaces.

Sorry for the late update. I tackled this on July 22nd. I replaced the water pump, all hoses, thermostat housing, thermostat, radiator cap, belt, tensioner & idler pulley. I thought about the fan clutch but ended up keeping the old one for now.

I did end up pulling the radiator which made the task very tolerable. Only had one challenge, one of the locating nipples had sheared from the tensioner and was stuck in the block. Also apparently the tensioner was broken for who knows how long. Took me 4 hours'ish start to finish. I didn't feel like it took that long but it did, I thought was done so much quicker than I actually was, guess I was having fun???

How long has this been this way I wonder?

I was on the struggle bus for a bit on this little but of joy. But vice grips and a hammer were persuasive.

Started around 9:30 and was finished before 2pm. Also the garage was a little warm by the time I closed the hood, and the sun hadn't even got to that side of the house yet. Ugh.

All buttoned up and shake down run to the beach went without issue. Also... whens the last time you flew a kite??? Was gifted this Shark kite and not gonna lie, it was fun!
