I have noticed with increasing frequency that my when I am sitting idle in the car that my engine temp rises till it is very near the top of the gauge, at which time the AC cuts off and blows hot air on me. Once I start moving again, everything is fine, which make sense because the air is then running over the radiator. I have also noticed that my fan still runs after I have gotten out of the car, so I don't think it is the fan motor?

Anyway, just curious if anyone else has had a similar problem so I know what to expect?

 

sounds weird as hell. Check that fan out...

 

That happened to my friends Type-S all he did was just rev the engine once and it the temp went down. never was a problem in the long run just one of those annoying things.

 

Your water pump is going out the door. Better get it replaced quick or you will kill your engine.

 

Check your raditor overflow tube!

 

Possible air in the coolant lines

 

My money is still on the water pump. A continual running fan is a sign of failure of a water pump. Touch your upper and lower radiator hose, if they are burning hot, it's the pump.

Air in coolant lines will only spike the temp gauge. Radiator overflow tube? Doesn't tell much about cooling except the level of the coolant available in the reservoir.

 

My car was doing the same thing, overheating while stoped. Took it to the dealer and they found the overflow tube came out of the overflow tank. No more overheating!

 

could also be the thermostat..

 

Top it off with coolant.....voila...fixed!

 

Considering there aren't many cooling parts that fail on this car, it's more likely air in the cooling system. My car did it one time. I topped off the coolant & it hasn't come back.

 

You should try fixing things in the cheapest order.

1. Check out the fluid. Make sure no air in the coolant.
2. Check/replace t-stat, fan switch.
3. If still doing it, replace water pump.

 

Are you still under warranty? Extended warranty? If it is the water pump have them do the timing belt at the same time. Won't cost you anymore except for the cost of the belt.

 

always do cheapest first. My first thought was thermostat, but it could be caused by any of those things.

 

Radiator cap may have gone bad as well, but from the symptoms it doesn't seem likely.

 

thanks for all the input... I am going to top it off with coolant first, and I will probably see tomorrow on my commute if that fixes the problem. If not, I wonder how much a replacement fan motor is? I know one fan works, but I am not sure that both of them do. How much effort is it to replace the thermostat?

Anyone know of an online site where I can order these types of parts?

 

I was wondering if dealer will replace the timing belt and water pump if I have the extended warranty from Acura Care ?

 

also another question, if I replace the timing belt at a local car shop, does it void the extended warranty I have with Acura Care ?

 

If it is the water pump that has failed they will cover it and i'd have them replace the timing belt at the same time. You need to remove the timing belt to remove the water pump.

 

I would suggest replacing the fan switch and t-stat first, before you replace the motor. This install is quite simple.

 

guys....its almost certainly the belts slipping or coolant low .....my wifes accord was doing this exact thing ..added about .5 gallons of fluid and all fixed

 

Ok, this PISSES me off. It was almost half a gallon low on coolant. I take my car in to have the oil changed and EVERY place says that they top off the coolant.... I even looked at my last receipt, and yes the mechanic check the box for topped off coolant. LIES, ALL LIES.

By the way, that fixed the problem... drove 600 miles this weekend, no problem.

 

Good to hear!
