The car was fine the temp never got over 180 i was racing and then park the car. i saw fluid leaking found out it was a bad cap. put a new cap and thermostat in and now the car is getting over 230 the fan wont come on unless the ac is on

Hi there, it sounds like you have a couple of things possibly, with an attempt to fix by a part replacement, and a good choice for a guess in the thermostat, and in most cases probably would have fixed it. But not your car right?The next step then I think would be to thoroughly inspect your cooling system, grab a Flashlight and check all fittings/clamps-tighten if loose, check hose's and radiator (if radiator is plastic it could have a hairline crack) check with car running and with it off, while running and in Park, remember to put on your emergency brake. Check reservoir cap, the cooling systems operate under pressure, and the cap on reservoir is important for system to operate correctly. If you have just been adding water and not coolant, your engine will heat up quicker, coolant serves as a lubricant for cooling system and engine block and as a system fluid needed for engine to operate to specs. Check coolant if any, if not add some immediately, get the already diluted type. Keep an eye on your temp guage when driving, if temp begins to rise, turn your car heat on high, and you should see your temp guage go down.If you are going through fluid you more than likely have a leak.If waterpump is leaking, it will need replaced immediately. waterpump leaking, in most cases you will notice a small puddle of water under center of engine area

when cold is radiator full? then remove cap start engine and see if the fluid is moving turn heater on full blast
if not moving thermostat is closed or water pump is shot
check stat put in can of water with temp gauge to see if it will open at 180 or what ever temp you jeep calls for no open cheap fix replace pump good? take belt off pum and see if shaft is loose
or leaking best to replace now then on the road

Remove the thermostat and place it in a some sort of container that you can use to boil water. heat the water and watch the temp (you will need a cooking thermometer to monitor the water temp.)
The thermostat should have a number stamped on it which is the temp it is supposed to open, most likely it will be 190, might be 180. watch the thermostat as the water temp approaches 180 and up.....you want to see when it opens. If it is bad it will probably open late (above 190) or the opening will be small and not allowing the water to flow as it should.
The simplest solution is just to buy a new thermostat and gasket. They should cost about $15

Depends in the mileage since the transmission was last serviced. It sounds like low pressure from the pump. It could be just a filter. You did not say where the leaking seal is, but a leaking seal will not fix itself.

New thermostat, installed, saw, new coolant made a little mess filling reservoir, (normal) checked fan fuse for some reason, and condenser fan fuse (xxx ?:), and temp guage, is slightly lower on gauge (than normal?) (disconnected xxxx? quit? a bit? to get to thermosta?.t no dash warning lights have a feeling I popped a relay.

Answer:

ok, you did a coolant service with STAT,

and it failed.

tell us what works right and wrong, symptoms only.

over heating? parked, (fan never comes on)? as it hits 225F?

under heating? ( fan stuck on , up North can cause huge cold engine)

dash gauge stuck low. (thermostat wrong heat range 180f is best. see FSM for spec. on this temp. spec..

Dash guage varies.? oddly (air in system)?

Dash gauge too high.? (Stat put in upside-down or bleed hole (jiggle) not UP side. higher side of mount , trapping air.)

Does something wrong happen only driving?

leaks?

does cap on rad hold 12-14psi pressure, hot.?

if car has fan belts, are they tight? (for sure water pump does)

can you see the fluid circulate? with the cap of(radiator cap) see if the fluid moves around.
does it overheats? give me more info

Look at the area where you park. Is there any fluid under the car that is not oily but rather is slick and has a sweet smell - yes, you wil have to stick your finger in it to see. If you find this type of fluid, you have a leak from somewhere in the engine compartment. Judge by the amount of fluid whether this is a major and potential calamity. (Lots of antifreeze could mean a bad hose or a bad water pump.)

Once you've checked for leaks, check the plastic reservoir that holds the radiator coolant overflow - is there anything in it? If you found alot of fluid on the ground, odds are that the reservoir will be low. If it is much below the fill line, add some water and coolant (50/50 mix) until it is back to the fill line.and check it for awhile to see if it needs more after you have driven for a bit (keep the coolant with you in the car just in case.) When the engine is cold, and as you are checking the reservoir, remove the radiator cap by pushing down on it a bit and turning it in the direction shown on the cap itself. Look into the radiator with a flashlight to see where the fluid level is. If it is more than 2 inches from the top, add a bit of coolant/water but not up to the top. Replace the cap firmly and add coolant/water to the reservoir cold level mark.
If that all looks fine, you may have a bad water pump, a plugged radiator, a week cooling fan or a bad thermostat.

Good luck.

make sure the engine is fully warmed up (check the temp gauge and feel the top hose from the radiator to the engine) that hose should be HOT and it you should NOT be able to calopse it-it should feel hard. If you do not have a leak under these conditions, you probably just have an overfull surge tank and it 'puked' out some fluid. If you top radiator hose is NOT hard after the engine is fully warmed up, you have something wrong-it could be as simple as a radiator cap that is not sealing properly, or a leaky hose, an intake manifold leak, or an internal leak in the engine (don't rule out a leaking radiator, it has end tanks that can and do leak).

It could be a number of places. I assume you mean that the coolant is leaking. You need to get it pressure tested to find the leak if it is not "dripping" where you can see it.

ok here we go and you aren't going to believe it...
I replaced the thermostat step one

I noticed that I had a small leak at the engine side of upper hose fixed that by taking it off and cleaning it and putting the hose back on Step two

then while refilling the reservoir with coolant i found that the hose that was supposed to be in the fluid was curled up on top and not sticking down in the fluid where it should be.
played with the hose until i got it to fall down in the reservoir where it should be Step 3

I started the car with the radiator cap off and let it run until it got to normal operating temp. and keep filling the radiator with fluid until the level stayed constant. Then put the cap back on and test drove. Everything worked fine haven't had that much heat in awhile and it kept blowing hot even when i stopped and let it idle for ten min.during test drive. Checked reservoir when I got home and had to add a small amount of coolant but not much.

I really think that the hose in the reservoir not being in the right place and pulling air into the system instead of coolant is the real culprit of this drama, but i replaced the thermostat to be safe.
