Hi all....
I'm having a weird coolant problem with my Mom's Elantra. I believe it's a 96 model.
Over the past few weeks she had noticed the car overheating. I didn't have much time to work on the car so I just kept filling up the reservoir and the rad with fresh liquid until such time that I was able to spend some time on the problem.
So I got into it last night. I briefly pressurized the system to about
30 PSI (probably too much) and found a small leak on the output of the thermostat. I fixed it by replacing the original hose clamp with a garden hose clamp, thightened it and the leak was gone.So I topped up the rad and the reservoir with water and off I went for a test drive. The outside temp was about 70 degs at the time. Within about 5 minutes of driving, the temperature gauge sat in the center of the scale. Another 5 or 10 minutes went by and both rad fans came on (stopped to doublecheck), which I found weird since my Saturn doesn't do that unless it's hot out and I'm stuck in stop and go traffic. The needle sat pretty much in the center except for a couple of occassions when it went a little higher, but then dropped again.
When I got home, I let the car cool down and noticed it was missing about a quart of water. Oil appears to be fine, there is no coolant smell in the car when running the heater, and the car doesn't blow white smoke.
Pressurized the system again but could not find any evidence of a leak anywhere.
One thing that I have noticed (not sure if related to the above problem) was that the engine ran a little rough when stopped. The SES light in on constantly except for a couple of times it would flash when stopped at a light. Again, I'm not sure if it is related.
I will be getting a scan tool to check for errors in the next couple of nights but until then I'm confused as to where the coolant might have gone.
Any ideas I should look into would be greatly appreciated.
Thanks Alex
