When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.

===

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BEKIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostatmy car is running hot have new water pump i`ve - 2_bing.gif open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may bepartially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do ahydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

Coolant leak


It is possible that the housing for the water pump has corroded and the new(hopefully) gasket is unable to seal off properly. Water pumps have a bleed hole underneath before the bearing so that in the event of the seal leaking the water will run out and not affect the bearing. May be the housing was not cleaned properly and a piece of old gasket is preventing the new gasket for fitting properly. If you have doubts that he did the job go back and front him to get the job done properly. Remember that in future the replaced part is yours and you have rights in law to take the old part home with you to prove it was changed.

lean motors run hot so check for air leaks including brake booster hose. check ignition timing for too far advanced . Check that the thermostat has the correct opening temp setting or is even the correct type for the vehicle. check that the bottom radiator hose dosen\'t suck in on revs restricting the water flow.It it\'s an auto check that the gears are operating correctly especially if there is an o/drive facility.Replace the lead giving you pain

Ihave a 99 vw passat 1.8 ,replaced head timing belt,gear,and cover,new water pump,thermostat,and overheats very quickly.it has 2 fans,1 electric the other is driven by beltsand is with fan clutch,clut


First, Ronald is an IDIOT! DO NOT power wash the engine EVER! If the engine is really hot and you spray ice cold water on it can crack the head instantly! Also, everyone knows' water and electricity don't mix! the ignition control module is $300. A little water on that and its gone!
If your car is overheating, you may need a water pump! The one you got, may have been bad! The rule is, as soon as a car overheats, the thermostat MUST be changed! A simple test would be to remove the thermostat and close it back up! A few dollars for the gasket is all you will spend! Try and run the car without it and see if it still gets hot! If it still gets hot, check the water in the radiator or resivor to see if the water is also hot. If its hot then the water pump is working and you need to check the fans! You can run a power wire to the fan to make sure they are working. There are relays for those also! If they are not turning on, that is most likely your problem! I rebuild VW's for a living!

There are several possible causes for it running hot.
  1. Loose drive belt - loose or worn drive belt would slip and cause the water pump to turn slower than it should
  2. Bad bearing in water pump - accompanied by occasional screeching and possible leaking
  3. Bad thermostat - this could be the case if you've used a radiator sealant that could cause the thermostat to stick
  4. Possible bad head gasket - this would produce white smoke from the tailpipe and bubbling of the auto transmission fluid

If it has no thermostat in it then your problem is the water pump or a cracked Cylinder or Blown head gasket. Check your cylinders for water and proper compression. If you have High compression on some but not all cylinders then you have a problem your going to have to fix soon as it will only get worse.

96 nissan altima with ne water pump and thermostat


1. Improper water circulation: Sometimes, eventhough you are sure that you have enough water on your radiator, your car still overheats. It might probably be that the water is cannot circulate properly, which results to improper cooling process. There are several reasons for this which you can discover by yourself. To verify if the water circulates properly, start your engine without the radiator cap. If water circulation is good, you should notice that the water pops smoothly over the top but still retains the amount. Another way to check, detach one of the ends of your radiator hose from your radiator and see if water flows continously over.
If water doesn’t circulates well, check the thermostat if it’s open. It should be open, meaning clean, and the water can pass through it.
If thermostat is clean and still the water doesn’t circulate properly, then you have to check the water pump. That’s probably where the problem is. A little leak on the pump will cause improper flow of water through the radiator system.
If you are sure that the problem is not about water circulation, another thing you can consider is check the engine oil. Very low amount of oil can cause greater friction of the mechanical system of your engine. If it’s not time to change oil yet, you can add over some amount of oil until advisable amount is reached.
While we can’t be always sure about our engine, especially if it’s not new, we should be prepared when it happens. Bringing extra gallon of water in your trunk will surely help.
