Hi Shane,

Check the radiator coolant level again.
Check if the fans are working.
Check the radiator cap.
Check the thermostat.

I recently got my a/c charged and have been using it for about a week. Today I drove around, with a/c on about 25-35 miles. It is a hot day, about 98 degrees not including heat index. When I got home I heard a hissing under the hood and antifreeze on the ground. I opened the hood and saw the antifreeze was coming from the overflow cap/hose. I turned the ignition, without turning car on, to check the temp and it was normal, not overheating. What could be the problem?

Hi CrazyB131313,

Check if the cooling fans are working with AC turned ON.

Next to check would be the radiator cap. Look out for worn seals.

I have a serious problem here. im hoping it isnt as bad as it looks but im no expert.

When the engine gets hot the car overheats. I have replace the thermostat and radiator only to find the coolant leaking really really bad from behind the engine.

THe leak is located about a foot down from the Oil Cap on the backside of the engine on the drivers side. Here is a picture that i took from a video i took from it. Here is the youtube video link as well of the leak. Any Help would be appreciated.

Hi emhsdude,

The video did not show very clearly where the leak is coming from. If you get under the vehicle, yu should be able to see where the leak is coming from.

At that area, possible leakagesa are from :
1. Water pump.
2. Water passage leading to water pump from thermostat.
3. Heater bypass hose.

My mother in laws 1994 Honda accord is leaking coolant rapidly from the back side of the engine on the passenger side. It is really hard to tell from top and below where the leak originates from, engine compartment is so cramped. Any suggestions? Waterpump or coreplug?

There are a couple of thoughts. The Idle Air Control valve on the engine has some smaller hoses that could have failed and could be leaking. It is possible that the water pump is failing. That fluid leak should tend to be located on the side or rear around the belts. You might have to lift the car or put on ramps to look from underneath the vehicle to see if the source of the leak is a hose on the back side of the vehicle.

My car started overheating, I replaced the thermostat about a year ago. Today I replaced the radiator and it is still doing it. The guage gets to half way after about 2 miles. When I stop white smoke(steam) that smells like anti-freeze comes out.

Hi firemann247,

You have a possible fault with the head gasket.

Does the coolant level in radiator goes down?
Have a pressure test done to confirm if the head gasket is good.

How much should I expect to pay to replace the bypass hose? Also, there's another oil leak, but I do not know where it's coming from, but it is in the same vicinity as the hose.

Doing a hose depending on where the hose is located, will determine how long it will take to do, where is the hose located? (Vacinity)

Back in October 09 water pump went out and engine overheated. Got water pump fixed, but when first start up afterwards seems to be a slight miss in engine. Other day noticed no coolant in radiator. Mechanic put about 1 gal of coolant in and did pressure test, but said no loss of pressure but did not know where fluid went. I saw no leakage puddles or such either beforehand. No white smoke in exhaust, oil looks fine. Few days later noticed coolant on top of radiator by cap. Next day top radiator hose blew out. Replaced it and cap. Now heat gage flucuates up high and back down again over and over, but not in red zone and again notice coolant puddle on top of radiator by cap. Seems like a lot of pressure in radiator. Also, top hose is hot after driving so seems thermostat is opening ok? Any suggestions on what to do next?

Hi teddyjoe,

High possibility you have a bad head gasket.

There are test kis available at your local parts store for testing the presence of carbon in the cooling system. Get it done.

When overheating occurs for this engine, it somtimes takes a few months for the gasket fault to become full blown as the gasket is the steel tye and does not warp easily.

Is the car not running quite as well as it used to? Does it seem not to have the power that it had? I am guessing that you are burning water. This is probably a head gasket problem and if not it is a head crack or warpage.

Some auto repair shops will inspect the head for warpage and cracking. They can usually plane the head and do all of this for about $80. Cost of a head gasket is minimal and you are back in business. I know there is some work in getting the head off. It takes me about and hour and 1/2 to do so.

You may want to get your mechanic to do a compression test or a leak down test to pin point your probem with your car losing coolant. Are you seeing any white smoke while you are driving the car. If so Bruce is right that either you have a blown head gasket or a damage cylinder head.

My engine has a coolant leak coming from the backside of the lower timing belt cover-just to the inside of the cover on the engine. There appears to be a small circle hole that the coolant is coming from. What is this hole and why is coolant leaking from it? What should I do?

I would like to know more about the engine, but I would wager that it is a 2.2L 4 cylinder. If that is the case I would say that the water pump is going out. That is located under the timing covers. When you replace it take the time to do the timing belt too. I even take the opportunity to replace the oil pump as well. That is optional.

I had the timing belt replaced within the last 10,000 miles and supposedly the water pump also. Is there any way to diagnose other than having the engine all opened up. Will this require a mechanic to do the job all over again at the same cost?

If the work was done that recently, there should be a warranty on the parts. The only other possible cause of a coolant leak in that area is because of head gasket leak.
