Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

SOURCE: Aloha,have 98 base mustang, overheating after many replacements

Do the radiator fans come on? Turn on the A/C which should start the fans automatically. Does that stop the overheating? Replace the temperature sensor if engine heat doesn't turn on the fans (A/C off). The water pump can be checked by removing the thermostat and lowering the water level in the radiator until the tubes are exposed at the top. With the engine cold, start it and watch for water being pumped into the radiator (it should be a fair quantity), which points to an effective water pump. Shut off the engine, replace the thermostat, and refill with coolant.

Replace the thermostat. It will be fine after that. I know thats what everyone says anytime there is an overheating problem but in this case with the way the system works and it has been working fine up to this point, it's gonna be the thermostat.

SOURCE: engine overheating

The coolant flush on radiator doesn't do any good. Since you have changed all the key components and still gotten overheated, then the root cause of the problem is the radiator. It got clogged up in small tubes blocking coolant flow. No matter how good the water pump is working but the radiator got clogged up, coolant is not circulating therefore the heat from the engine can't be dissipated to the radiator. Replace your radiator, don't even think about rebuild it. It has been used for 11 years. Make sure to have the correct coolant/water ratio to keep radiator life for years. Good luck.

We changed thermostat sensor and thermostat, still over heating. What could it be?


overheating has many symptoms, not just green on the ground
do tell?


temp gauge lies its buns off... use a real tool called a thermometer to see real temps. we use a IR pyro gun to see it and not GET burnt.

gauges is telling truth, so......................


a bad rad cap, or bad thermostat are common fails.
test one: (dead cold engine) never hot.
radiator tank filler cap off , you look down there, is the level really low?
(forget the silly side expansion tank for now)
if found low , then fill it and burp it. no air allowed there
running 50% antifreeze now? no?, that its WRONG.
the tool is $2, test it. (Prestone sells it)
the coolant is all rusty color, (ill not comment ) try service.

  1. Green on the ground,? for passengers feet.
  2. Water exploding from overfill side tank? ( oil in RAD or Milky engine oil) (same milk in transmission pan?)Exploding gases, on cold start is bad head gasket or warped head or cracked head/block, or just simple overheating, The Rad leak down test and the exhaust test (green/blue ) tests solve this riddle easy.
  3. Steam rising from hood or Radcap, or hose to Cap and recovery tank. Over heating or leaks.
  4. Dash gauge pegged. (or WILD GAUGE swings "air pockets below thermostat") or gauge bad. sender bad.
  5. Motor pinging and loss of power. (do not allow pinging, it will wreck the engine)
  6. Pistons landing on ground? (just joking....)
  7. A/C dies?, does it?, due to A/C engine overheat switch ,tripping off. a 235 ?F (spec) see FSM. A/C means Air conditioner clutch dead.
  8. Does the engine over heat , if left idling a long time (30min-1hr). or only at stop signs or red lights? (clutch fan not activating , check it, this way.)
  9. Does it only over heat while moving ? ( a bad pump, or Rad)
  10. Overheats, only on hills? (bad RAD)
  11. Only overheats pulling heavy loads ? (inside, full of bricks, or pulling a 1000 trailer ? ONLY?
  12. Never overheats moving fast on flat ground. (so the RAD fan is dead, no mater if stock or hacked in electric fan, it's DEAD)
  13. Do you have carbon or oil floating around in the Rad, filler CAP neck top tank ? yes?, that is bad head gasket or worse cracked block/head. Do the Exhaust test.
  14. Overheats under all conditions, Catastrophic overheat. ( can be bad pump (rotor gone) or RAD or system is packed up)
  15. Seems to overheat , even at first start , in 1min or less I have gases shooting into the overfill tank, that is a bad head gasket (mostly a warped head, at least)
  16. Antifreeze (and water) in the pans, Engine or Transmission.
  17. The RAD fan is DEAD ( just because a mechanical RAD fan coasts, don't mean it WORKS RIGHT.) See the clutch tests below. if electric fan , there is a test in the FSM covers this 100% the fan must come on over heated,.
  18. my electric fan , starts to run idling engine long time at 225F. It kicks on, some cars have 2 fan and staged, come on trip points.
  19. RTM read the manual the FSM>
  20. there is more im sure, cant think of them all now.

That pyro gun allows me to test any RAD easy , ask.
ok , i check all rad tube top and bottom and bingo find any tube clogged fast. if all are equally clogged.(partial) i cant find that.
that is caused by zero service, so...and there are signs for that too.

Overheating


Boiling over, of just running Hot? If running hot, leave the rad cap off, let the engine come up to operating temperature. Put a probe into the rad, check the temperature. If temp is ok. I would lean toward a failing temp sending unit.
Check restriction in the rad, make sure it isn't plugged.
Is there loss of power? maybe the exhaust system is restricted.
Hope this helps.

How to change thermostat on 2000 caravan


Follow top rad hose to the housing remove two bolts on housing that the hose attaches to after removing rad hose on engine side, pop housing off and change thermostat. Once changed reverse procedure start vehicle with cap off filling antifreeze watching your temp guage and wait for the fans to come on to work air locks out of system. Once fans have cycled and level has dropped you should have good heat and be able to cap your rad. DONE! Be careful not to get burned!

Engine keeps overheating


I'd start with replacing thermostat (that's the most common fault) Other possibilities; waterpump,leaky hose, radiator cap (not holding pressure), fan belt broken. I'd inspect for belt & leaks - if good replace thermostat.

No heat or air barely enough to keep front windshield defrosted


If engine temp is not at normal, change thermostat. If it is, check for trapped air in system.
with cold engine, loosen radiator cap & stART ENGINE, RUN TILL UPPER HOSE GETS HOT (meaning thermostat has opened), then see if air burps out of cap. Shut off engine and keep rad full as engine cools down.thighten cap & keep reservoir full.

Did upper hose get hot?

Radiator blew at seam replaced radiator and cap, every thing systematic fan and all. now engine light came on engine and radiator hot to touch


Did you run engine from cold, and add coolant as needed, with HEATER ON, when you were re-filling the system after replacing rad? If not, do so, and leave cap off until rad fan comes on & off 2 or 3 times, then put cap back on & try it.

Vehicle needs to purge all the air form the radiator. Jeep Grand


Start vehicle when cold. remove rad cap, start engine & put heater on (not defrost) and let it run for a while & top up rad as coolant goes down, to about an inch or 2 from top of rad. If you have electric rad fans, watch temperature gauge and around normal operating temperature or slightly above, they should come on for a minute or 2 then shut off. If not electric fans, just watch in top of rad for increased flow through rad, indicating thermostat has opened & coolant is circulating. Rev engine slightly every once in a while for 5 or 10 seconds just to help increase flow etc to help assist bleeding air out faster. Watch for increased flow in rad, 2 or 3 times at least, or listen for fan to go on & off 2 or 3 times before putting rad cap back on. As your doing this, keep topping up rad if it needs it. Make sure rad cap on all the way, check coolant return bottle level & add to mark if required, and you should be good to go. One of the things people forget to do the most, is to turn heater on while doing this, and that is usually what causes a lot of airlocks in the system, so don't forget that step.

2002 pt cruiser overheating was told i need a new raditor and thermostat for 1 grand sounds fishy


Flush rad & change coolant & thermostat. Check operation of rad fan, & make sure it is coming on when engine reaches normal operating temperature. Be sure to bleed air out good when refilling rad/cooling system. Start engine & turn heater on when refilling & let rad fan come on & off at least 2 or 3 times before putting cap back on rad, and refill rad as needed as you do this. then fill return bottle to proper level & see what happens.

Car over heating when stopped in traffic but not when movin


Hi. the first test will be to open the hood and inspect the cooling fans. check to see if the fans are activating in intervals during the running cycle. if you don't see any fan rotation at all, this will confirm cooling fan failure and you will need to replace the fans or fan relay. Now, if the fans are running and the car is continuing to run hot when stopped, i would move to the next inspection point. the next problem spot will be a faulty water pump or faulty thermostat


If these two devices are malfunction in any way, it will cause the symptoms you are experiencing. at this point. the first thing is to make sure those fans are actually working.


Please rate and have a great day:)
