Cooling System Rebuild Checklist

I will be rebuilding my cooling system and wanted to see if there was anything I am missing or if anyone has feedback on the parts I am purchasing. Most parts will be bought on RockAuto

1994 192,000 miles

Fan Clutch
Hayden 2625
I was going to go with a ZJ but I’m not sure if I want to deal with the added noise

Serpentine Belt
Gates K060975

Thermostat
RobertShaw 330 Hi Flo balanced sleeve 195°

Thermostat Housing
Gates CO34741 or Hesco HFTH 4
Depends if I decide to put my temp gauge sensor on housing or heater hose. Might just reuse the stock one.

Thermostat Gasket
Fel-Pro 35024
RTV or no?

Water Pump
Gates 42004
Current water pump still works so I may just keep this as a spare. Haven’t decided yet.

Water Pump Inlet Tube
Motorad CH5920

Water Pump Gasket
Fel-Pro 35582 or 35629
I actually don’t know which is the correct one. Anyone know?

Radiator
Spectra Premium CU1193 or CSF 1 Row
Will probably go Spectra

Radiator Hoses
Upper: Gates 21616
Lower: Gates 21615
Heater: Gates 28491 5/8 Inner Diameter x 6ft

Radiator Cap
Gates 31516 16lb with safety release

Coolant
Prestone 50/50
Theres like 300 different options for this. Not exactly sure which one I should go with

Coolant Flush
Prestone rad flush or thermocure
I dont know how bad the cooling system is so I may wait till I do an initial flush to decide if I need to use either of these.

Has anyone cleaned their coolant reservoir? Mine is very dirty above the fluid. I cant imagine thats a great sign for my cooling system lol

Any feedback, advice, criticisms is appreciated

CSF 1 Row, CSF 2 Row, Spectra radiator for light to light driving and road tripping in South Florida?

Need to replace my rad, seen these 3 pop up the most. Is the CSF2 row really worth $140 more than the other two?

Is the 43% thicker core of the CSF 1 row actually better than the spectra? They are the same price.

Mostly street driven in South Florida but will be occasionally used for road tripping.

New coolant temp gauge reading 175-180° & tons of heat coming from trans tunnel

Hello, I just got new gauges installed and I see that my new to me 94 XJ temps are around 170-180° while driving (photo shown while car is off)

Could this be because a previous owner put in a lower temp Tstat or more likely the mounting of the sensors? I know this is well below optimal operating temps.

I also wanted to mention that I have a ton of heat coming from my transmission tunnel. I recently lined it with some Siless 80mil but it’s still pumping out so much heat. From what I can tell a previous owner did install an upgraded trans cooler (pic 4) but it is still looped into the coolant rad not its own loop. I also cant tell if the rad that is in there is stock or not if anyone may know.

Oil pressure is around 20 warm idle and 50 driving around which I think is pretty good?

Redoing window trim

I have the typical peeling window trim and was looking for some feedback on what I plan on doing.

So I will take them off and strip them with paint stripper

Prime with Rust-oleum Stops Rust Automotive Primer

Paint with SEM Ultra Black Matte

Should I sand it as well?

KSuspension Injector alternatives?

I was going to buy the 4 hole injectors from Ksuspension for my 94 (EV1) but they are on backorder. I looked into precision auto injectors but they are significantly more expensive.

Anyone recommend any other 4 hole injectors?

Anyone have inside info on when they wont be back ordered? I just started looking into them so i dont know how long its been like that for.

Yet another Vapor Lock question

Hey, my 94 runs fine in my usual stop and go traffic, running around town errands, commute. After maybe an hour of driving and turning it off at various different places when I go to start it has a very rough idle and shuts off. I then turn it back on and after maybe 20 seconds of rough idle it seems to be just fine again. After this hour the interior also gets insanely hot. I had my laptop on the back floor and when I went to pick it up I couldn’t even touch it without a glove. I figure it’s probably because of how hot the engine bay gets which may be causing vapor lock on the restart. Can anyone confirm?

I was looking at the DEI injector heat shield but I noticed it says 97-01 anyone know of a kit that works for 94s?

Towed for the first time this week to pick up my new to me 94 Jeep XJ

25 Laramie SO Hurricane 3.55 gears

~3400 lb car and 1900lb trailer

Towed great, I took it pretty slow 65MPH empty trailer and 55-60MPH loaded. Started at 40PSI with the empty trailer but halfway through the 6 hour drive I lowered to 37 because it was so bouncy and stayed at 37 when loaded.

Funny enough I got the same or better miles per gallon (14.7-15) that I do in my day to day driving which to be fair is all light to light city driving.

Trailer is a rented 18ft Timpte 10Klb drop deck

Best place to but high quality prescription sunglasses lenses

Hello, I recently lost my sunglasses and purchased some new frames to replace them. I was going to take them to costco but they don’t take sunglasses.

My previous sunglasses were done at lense crafters but they are far too expensive.

I am looking for an online retailer that I can have make high quality lenses for my Ray Ban sunglasses. Lens Direct has good prices but I am unsure if they are any good.

Ray-bans lenses or Costco Lenses

I have to replace my sunglasses because I lost them. Lens crafters has a sale going on right now and purchasing through them would be $140 for the frames and $247 for the prescription. Alternatively I can go to costco and get my prescription there for what I assume would be maybe $100 less? Is it worth it to go with lens crafters or should I go with Costco

Just bought Adams Graphene Spray Advanced. What is your process of applying?

Hello, I have watched the video that Adams made about it but I have seen so much mixed responses to the proper prep and application of this product that I am unsure what the best process is.

I was planning on washing and drying, clay mitt with adams detail spray, wash and dry, and then applying the graphene spray. I live in South Florida, I was planning on doing all of this outside in the sun or maybe in the evening.

Is this an okay process? Do I have to clay mitt?
