Water in KIA Carnival (Australia) keeps overheating and building up pressure in overflow bottle, then squirting out. Could this be Thermostat problems? If so where in engine is it situated and how hard is...


G'day Noel,
Yes it could be the themostat. It is located inside a little housing at the top front of the engine. Replacement is straight forward. Remove any cowls or covers obstructing your view of the top radiator hose where it attaches to the engine. Drain the coolant from the system by undoing the bottom radiator hose. You may want to catch this fluid for later use. Remove the top radiator hose. Undo the three bolts holding the thermostat housing and gently tap if free with a screwdriver handle. Clean and inspect the housing for corrosion damage. Fit new themostat and refit the housing using a new gasket. Note: make sure you put the themostat back the same way it came out. Tighten housing bolts, replace radiator top and bottom hoses and fill with coolant. Do not fit radiator cap at this point. Start and run engine until you feel hot water arrive in the top of the radiator and all air has been dispelled. Shut off the engine and top up the radiator coolant. Do this again after it has cooled down and before attempting any long trips check it again. Do not open the radiator cap when the engine is hot. Also have a read of this article...http://motorsm.com/complaints/update/display.asp?aid=2621

How to replace themostat


It is located on the right side of the engine if you are looking under the hood. Follow the black radiator hose on the right all the way up to the engine and there is the thermostat housing. You will need a 10mm socket to remove three bolts and the housing and thermostat will come right off. Make sure when installing the new one that you have the spring side of the thermostat inside the engine. It will now work if installed backwards. The new thermo should come with a black o-ring or gasket-make sure to replace. This job takes about 30min.

How do i change thermostadt on jeep cherokee


  1. Follow your upper raidator hose untill you find the themostat housing which is the ending point for the hose.
  2. Remove the two bolts that hold the housing (you may have to loosen the belt to get to one of the bolts).
  3. Remove housing and replace themostat and gasket ( remove any excess gasket that may have been left over ).
THE DETAILED PROCEDURE IS GIVEN BELOW
  1. Open draincock on the radiator to drain the coolant from your Jeep Grand Cherokee. This draincock is located on the lower right side facing the rear of your Cherokee.
  2. Use a sealable container and reuse the coolant if it is relatively new and clean.
  3. Follow the upper radiator hose to the point where it meets the thermostat housing. The thermosat is located inside the housing.
  4. Use a clamp tool or vise-grip pliers to loosen the clamp holding the hose to the housing. Work the end of the radiator hose free of the thermostat housing.
  5. Remove two bolts holding on the thermostat housing cover. Pull off the cover.
  6. Take note of the position of the old thermostat. Remove and install the new thermostat in exactly the same position.
  7. Scrape off residue of the old thermostat gasket from the inside of the thermostat housing cover using a razor blade. Avoid getting any debris inside the thermostat housing.
  8. Install the new gasket. Reattach the thermostat housing cover and radiator hose. Start your Jeep and run the heater on high. Allow the engine to warm up. Check for leaks.
