Heatng Problem! I replaced the timing belt of my car. I also replaced the water pump. Once done, I started the car and it runs perfect. The problem I made was to break the electric pin for the temp sensor. So I fitted a brand new sensor. Now I find my Kia heaing up. The temp guage is always at the 3/4 point. The guage drops at time but fluctuates in the 3/4 level. What could be my problem??

Yes, it is an interference engine. Serious damage has occurred.. sorry!.

Check fuel pressure, injectors and ECU.

Disconnect the battery, locate the idler bracket that adjust the tension on the belt. Loosen the bracket and unhook the belt off of the Idler bracket(no need to remove belt unless in the way) Remove water pump when car is cooled down. Loosen bolts that hold the water pump on and remove pump. Put new one on and reverse process. Replace your antifreeze/ water. Start car for thirty seconds. Stop car, look for leaks and top off antifreeze. Done deal.

Depends upon the source of the water leak. Common places to leak are at hose connections, the radiator core, the heater core, or the water pump. Once you have identified the source of the leak, repair or replace parts as needed. If you have a 6-clyinder model, the water pump is located behind the timing cover, driven by the timing belt. Many owners believe that the repair shop is trying to rip them off when thy recommend water pump replacement at timing belt replacement time and opt not to do it since the pump is working. Unfortunately, the new timing belt will cause a different wear pattern on the pump shaft and almost unfailingly, the pump will leak within a few weeks or months after the timing belt is done. Many shop now refuse to replace the timing belt without water pump replacement for this reason, or will make the owner sign a waiver of responsibility if they refuse the additional service/cost.

You had better check the timing belt again, you may have done something wrong and it skipped teeth.

It is common practice to replace the water pump when replacing the water pump also. If the timing belt has recently been replaced than it would not be necessary to replace it again. If the belt is original than it makes perfect sense to replace it when the water pump is replaced as the timing belt will need to be removed in order to replace the water pump. There is no additional labor coast just the additional parts cost of the timing belt.

When it is done you shouldn't have to worry about it for the next 100,000 miles or so.

If you don't replace it when you have the water pump replaced than down the road when the timing belt is due for service you will have to pay for all the labor costs again to replace the water pump.

well that is how I always sell a timing belt job also. The water pump is driven by the timing belt and it is very labor intensive to replace. I always replace the water pump also because you have to remove the timing belt to replace. I have had people refuse the water pump, and have to spend the same labor dollars a few months later when the pump went out. Even if not leaking it is always good insurance to replace the pump with the timing belt but is not a must just good idea.

The water pump on the 92 Laser is easily replaced. You just need to untension the the belt driving the bump. Once you have done that all you need to do is undo the bolts and take the pump into your local auto parts dealer. Now that you have the pump install it and retension the belt.

U actually have to remove alternator belt and powersteering/a/c belts, then remove timing belt cover, remove timing belt adjuster, and slide timing belt off top pulley, making sure you mark it before removing it, so as to put it back in same position. Next, unbolt 2 bolts at bottom of water pump (this is a bit fiddly, but doable, then, undo water pump, replace with new water pump, being sure to use gasket cement, aswell as new gasket, which should be supplied with pump, then put it all back together, in reverse order of removal. Fill cooling system, check for leaks, and voila, u have done it :)

Typically any timing belt replacement interval is 60k-75k miles. The book will however tell you 90k. Now it depends on what engine your Avalon came with. The 3.0 is a non interference engine meaning if it does snap, it will not cause any damage to your engine. The 3.5L engine however i dont know if its a interference engine or not but i dont see anywhere where it says it is. As always suggested, change your water pump as well, as it runs off the timing belt. Once i didnt change the water pump and a week later it locked up on me and ruined my perfect new timing belt. Truth be told :) lol

teh resaon he wants to replace your water pump is because it runs off of your timing belt.and if it should fail later down the road after belt replacement.then you will be looking at another big expense having the same job done twice.i would rcomend you do get the waterpump replaced also.as for you other problem im not sure. samboiv
