Default Timing Belt/Radiator/Water Pump/Heater

Car: 2003 Kia Rio

Previous Problems: Timing belt broke and caused $1,500.00 in repairs. The "head" had to be remachined, valves and cylinders needed to be replaced or repaired. I drove the car for a week. Then the radiator cracked. This cost $400 to replace. While replacing the radiator the mechanic showed me that my water pump was making a noise most likely to the "ball bearings" going bad, so I had that replaced. This cost another $400.00.

Current Problem: I just got my car back yesterday. While driving home I had the air conditioner on and it seemed that the temperature gauge on my dashboard was going up. I couldn't really tell 'cause it’s a short ride home. (I turned it on just to see if my car would still idle low with it on, after all these repairs.) Today however it was cold in the morning so on the way to work I was waiting for the temperature gauge to go up to the middle so I could turn the heater on. After going 26 miles at 65-70 mph it didn't budge but a tiny bit. I thought it was kind of moving, so just to see if my engine was hot I turned on the heater. It blew cold air and my temperature gauge started going back down. (Not that it had far to go down.) When I got to work, I opened the hood to check to see if the engine was hot. It was hot but really didn't seem too hot. I could touch the radiator with my bare hand and it was warm.

I called the mechanic shop and they said it could be the heater core. What I want to know is if this problem could have stemmed from incorrect repairs. If you can't tell I know nothing of auto mechanics. Yet, I have found out that in some way these items are all closely related. (That sounds stupid I know.) Also, is this something that I could change out myself? If it is not changed will my car stop working and fall apart? Is it the thermostat? Is the thermostat something I can change?

Help me please!

Welcome to the forum.

It sure does sound like a thermostat problem.

Without the thermostat installed it cannot reach normal operating temperature , and the fact that you noticed a slight drop in temperature when turning on the heater would confirm that the heater core is in order.

You mention the the temp went up with the AC on - this could be that the belt is not correctly tensioned and slipping with the AC on, but could also be due to other reasons as well.

I would start by getting the thermostat changed.

The thermostat ensures that the engine reaches operating temp as soon as possible and maintains this temperature because there is significantly more engine wear while the temperature is low.

BTW. The fact that the mechanic did not replace the water pump when doing the head and timing belt is a bad sign - the water pump itself is cheap, but the labor cost is high, but would have made no difference to the labor cost if done when the timing belt was done.

For service info register (free) with KiaTechInfo and click on 'Shop' on the left, and for elect schematics click on 'ETM'.

Quality and not quantity counts.

I agree with ron1004, sounds like the thermostat is stuck open thus the coolant is in constant circulation. Here is a link for service manual that will help you with changing the thermostat:

http://www.kia-forums.com/do-yoursel...e-manuals.html

Drain the radiator, remove thermostat housing, make sure there is not any gasket on the engine block or thermostat housing, install new thermostat with vent on top, gasket and thermostat housing, close radiator drain and refill radiator. Run the engine to normal operating temperature with the radiator cap off and heater conrol and fan set to high to let any air out of system, checking coolant level. Once you feel air is out of system install radiator cap. Make sure reserve tank coolant level is at max. Check coolant level after a couple engine warm up and shut off cycles.

Any questions do not be afraid to ask, we are here to help.

IMHO look for a different repair shop.

Good Luck

Thanks a great deal guys. I have one more question. I went to the mechanic last night. He said it could have been an air pocket still stuck in the lines and this could have caused the problem. I think to be safe, I'm just going to change the thermostat.

You don't know how much help this has been.

Okay, so you remember that I took my car to the mechanic and they said that the last problem I was experiencing was just "bubble" in the thermostat. Well, my car has been running rather rough for a day and again takes a very long time to heat up to normal. (According to the gauge.) Well, the mechanic that works for our company looked at it today and said that it blew a head gasket, which has already been repaired once.

I am wondering if all of this is because the shop that I have been taking it to, isn't doing a good enough job or if they have been making mistakes. Is it something that just happens or is it my fault?

I really appreciate the help for you guys as I know nothing of automotive mechanics.

In your first post you stated that the head was remachined, valves and cylinders needed to be replaced or repaired. I gather that there was a piston or piston's replaced. Was the engine block and head magnifluxed for cracks?? Was your work place mechanic able to do a clyinder leak down test to determine which clyinder it is? Are There any DTC codes set? How many miles do you have on the repairs for the broken timing belt?
When the radiator cracked did the engine overheat? Are you losing coolant now?

It is easy to point fingers but I am leaning towards a repair default. Just my opinion.
