|Cole Noah||Installed the temp unit, gauge reads at zero on a cold start instead of 110!|
|05-23-2013 12:29 AM|
A little update, gauge is still showing it to be running hot, but I can touch every part of the engine, not for long but I can touch everything without getting burnt, the gauge is still showing up at about 110 when I turn the ignition after a whole night of not running it.
The main hose from the radiator is hot, but it doesn't appear to be under pressure?
I got my thermostat but I'm waiting to get the new radiator to install it.

Bought a new radiator, it's on the way. Thermostat should be here soon.
Next I'm going to buy the temp sending unit
I'm ready to find this problem and fix it!

My 90 YJ did just the opposite it was blowing pressure in the Crankcase and blowing oil out, and had very low compression for a long time so I started building a Stroker a little at a time, then it blew the head gasket to to coolant side and ran HOT, so I changed the Head gasket and all was well except very low Oil Pressure, so I keep buying parts and having work on ported heads and regrind Crankshaft, all's left is the Block work, then changed the Carb. wow it run great! and then the oil sending unit starts leaking, Changed it, LOL oil pressure is great! Oh well! I guess my engine is good after all, now that I'm all most done with the new engine.
Some times we seam to change all the wrong parts trying to get to what's really wrong.
Have Your Coolant cheeked for gas in it!

I'm not 100% on your engine but that is what my 4 cylinder S10 was doing.

V belt is a thin belt. the pullies have a deep V groove in them. A Serpentine belt is a wide flat belt. The pullies are wide and have a few groves cut into them.
V Belt style pully
Serpentine style pully

If you start your Jeep, warm it up fully, and can remove the radiator cap without losing any fluid, you have a leak somewhere.
When your engine warms up, the coolant/water mix expands and forms pressure in the cooling system, if three is no pressure, the excess coolant mix is going somewhere, it doesn't just magically not happen.
Try pressure testing your cooling system and look for any leaks, no matter how small.

|roadyrob||v belt is standard rotation, reverse is serpentine.|

|theYeti||Alright buddy. Make sure you know for sure f you need the reverse fan clutch. If its supposed to be regular then it will run even hotter, make sure you get the right one. On my 90 is was a regular not reverse|

As far as I know I'm not over heating, not showing many signs.
I've bought a new radiator, radiator cap, and a thermostat. Now I guess I'm going to buy temp sending unit.

|banks316||Does it act like its over heating? Steam pouring out ect? YJ guages havnt been known for there accuracy. I replaced my temp unit after i broke my old one trying to remove the intake. Before I did i was running 210 on the nose. Now my gauge reads the same as your second pic. But shows no indication of overheating.|

|banks316||Temp sending unit? Its located on the back of the head driver side|
|05-18-2013 11:04 AM|
So I got in it this morning to drive around a bit, and as soon as I turn the key over for the radio and electronics to get power the temp gauge says this
Now that is a completely cold engine, which sat in the garage all night with the good up, an it's registering at like 108
So, I went for a drive and after it finally settle this is where the gauge was staying,
But it would also go back down to 210 sometimes, although that was rare.

|Cole Noah||Installed the new fan clutch. Still seems to be over heating|
|05-17-2013 08:38 PM|
|Cole Noah||Bought a new fan clutch, it's the only kind they had in stock at advance, it's a reverse fan clutch, they would have had to order a standard? Is this the right one?|

|Cole Noah||There is resistance! But not much at all, just enough to where If i push it hard, it wont spin by iitself.|
|05-17-2013 06:33 PM|
How hard would it be to replace the fan clutch?
I've seen them for about 50$ on morris 4x4
|05-17-2013 06:27 PM|
|roadyrob||check your fan clutch. drive it till its hot, shut it off and try to turn the fan. should be very hard to turn if the clutch is working. also, I assume you have a shroud, running without one will cause it to overheat.|
|05-17-2013 04:27 PM|
Seems to run hotter when the heat is on. The heat works, real good.
Need advice quickly this is my daily driver! Lol

|Cole Noah||Got a new cap today at the auto parts store, nothing changed|
|05-17-2013 01:09 PM|
Could it be my radiator cap? No matter how hot it is I can take it off, it seems like there's no pressure in it at all! I found out the water is moving, it started to bubble after I let it warm up.
I payed more attention to the gauge and it is sitting at about 240 give or take how I drive it
It's not losing fluid or water from what I can tell
The pump doesn't appear to be leaking.
|05-17-2013 11:29 AM|
Clutch fan didnt seem to have much tension, if any at all
|05-17-2013 11:25 AM|
Yesterday it was running almost on the red line! I added water to it and today it's running at the notch that's right after 210 which I guess is 250?
It's a i6 4.2 258
|05-17-2013 09:40 AM|
|frayedknot||When you increase in speed it increases the air flow through the radiator, usually an engine running hot at slow or stop speeds indicates a bad fan clutch. Turn it by hand there should be moderate tension from the clutch. Are you losing water? With the radiator cap off at idle and warmed up you should see the moving water through the radiator. Remove the cap before it gets hot!!! That will tell you if the water pump or flow of water is obstructed or impaired.|
