It sounds like a misfire when you explain the lack of power and the overheating could be from a leak in the system from a radiator cap that is bad. A 50/50 coolant water mixture boils at about 236 degrees Farenheit at ambient pressure. For every pound of pressure added to the system raises the boiling point 3 degrees. So a radiator cap with 10 lbs of pressure will raise the boiling point to 266 degrees. My point is that a bad cap releasing pressure instead of holding can over heat an engine very quickly. Just a reminder, never remove the thermostat on any computer controlled vehicles. The systems of today are made to run efficiently at 195 to 210 degrees Farenheit. Removing the thermostat will "trick" the ECM in to thinking the car is still warming up and it will never get out of that mode causing a richer fuel mixture and advanced timing that can result in overheating, a clogged catalytic converter, etc. I would replace the plug wires because they can go bad without any visual damage and replace the radiator cap to start. Turn on the A/C with the temperature setting on high/hot so the engine warms up gradually. Let me know any other information you may have so that I can assist you further. Is there any other information you can give me?

    the lack of power happened with and without the thermostat. now, it overheats with the thermostat in.

    drove it for an hour locally today with no thermostat. never overheated but no power. Still sputters upon acceleration.

    Radiator cap was changed, 16 psi. radiator was changed last year.

    replaced the spark plugs today. all gaped at .044

    Looking at a bad head gasket???? before i flushed the radiator and before i changed the oil, no milky mixture. and the oil and radiator fluid still look very clean. no smoke coming out of the muffler

    compression test on all cylinders tonight still read 215, 215 210 and 210

    since i thought it was a bad head gasket, i put k&w head gasket sealer in while bypassing the heater core and had the thermostat removed. same results

    spark plug wires were changed last year about 6,000 miles ago

    the specs for the compression on my car are 171 why am i blowing a 215? just asking. at least i have the same compression on all cylinders.

    car is a 1992 toyota celica gt 2.2 with 180,000 miles on it. changed the water pump and timing belt last year about 6.000 miles ago. could my timing belt have shifted causing the motor to run rough?

    I would say no to the timing belt shifting. If it stretched or was not tightened initially it could slip off which would cause it to be shredded apart and/or kill the motor if it broke. Is the engine idling rough sometimes, all the time or does it seem to run fine until you began to accelerate? I don't think I read in your response that you replaced the plug wires. A miss that is caused by a bad plug wire can cause the engine to bog at low rpm and when accelerating. It will then begin to run slightly better at higher rpm. I have seen many times where new parts are defective causing me to scratch my head. So, if you have no coolant leaks, no smell of coolant burning, no white smoke or excessive moisture at the exhaust pipe and you have gone through the cooling system, have you felt for air in the system that could be causing the thermostat to open late or not at all? I truly think that you either have a bad plug wire or wires, a cap/rotor or moisture in the distributor cap. Let me know about the air in the system. If we can start by solving the overheating issue it will make diagnosis of the other issues easier. Please get back to me. Thank you.

Saturn overheating

the stuff describe most likely from the anti boil -anti freeze mixture that has become ineffective for not being changed regularly and not up to percentage to do the job. It allows the aluminium parts of the car to corrode and what you see is the end result . It will deposit in the cores of the radiator and block them up resulting in a replacement radiator . You can expect corroded aluminium parts from all areas of the motor.

Heater problems 2009 dodge nitro v6.

Possible, with rad cap off, let vehicle idle until coolant fan comes on then shut vehicle off for 30 minute cool down. Top up rad, install cap and drive and recheck heater operation and any overheating.

Flush with fluid surpenion system why remove heating hose

surpenion system.? wow no year stated !!

what are you doing ,just a flush? of engine coolant

my guess you are reading the steps. and wonder why we do it fully

there are 2 flush ways. 1 is poor way and way 2 is ASE.

i will not mention shop way with the $10,000 machine.

1: poor way, open drain bottom rad, run water from rad cap

until drain runs clear. (ok on a 2 year old car. sure)

2 pro way.

he back flushs all cooling system parts and makes sure all flow good.

1: RAD (end to end)



4: THE BYpass hoses are flowing good.

other? sure. depends on engine option (size)

on my cars , IR pyro gun the rad tubes as a last check. (hot)

to be sure all tubes are working... ask.... a $15 tool , like no other.

it a choice,

I have no Heat in my 2000 Ford Taurus!

If the heater core bypass refers to the water flow to the heater core, I would wonder why you did not flush the heater core as part of the system. You can drain water from engine, disconnect heater hoses and add a short hose to the heater and force a garden hose to flush the core.

I have not looked up the particulars for which heater system is on your car. Some just use duct-work to close off air flow through the heater core and the heater core always has hot water in it. Others will use a valve to shut off the water flow through the heater core and they can be either electric or vacuum operated. Combination systems are the third system which controls water flow and duct air flow at the same time.

Some of the Premium Climate control systems with Electronic displays have a computer diagnostic system which self-diagnoses problems but you need the sequence codes and explanation of where the bad part is located.

Trying to bypass the heater core

The following suggestion is as old as the water cooled engine but it still works better than any solution you can buy at an auto parts store.

Total cost: $2.00

  1. Drain1.5 gallons of water from the radiator.
  2. Close the drain **** and add one gallon of boiling water.
  3. Pour in one pound of baking soda.
  4. Pour in one pint of distilled white vinegar.
  5. Replace the radiator cap immediately.
  6. Run your vehicle for fifteen minutes.
  7. Flush the radiator and fill with clean water.

If that didn't do the job, you are going to have it boiled out at your local radiator shop. The cost will be approx. $30.

I have a 1992 toyota camry le with a 3.0 v6. I'm having an issue with the heating system. It blows somewhat of warm air and not hot air? The engine warms up to normal operating temp. Do i need to change...

I would start by checking the hoses at the heater core. One should be hot the other cooler but still pretty warm. If one is hot and 1 is a lot cooler you probably have a plugged heater core. You can also check to see if you hear the blend door slamming and check air temp change when you switch from full cold to full hot. If there isn't a clunk at full hot or cold the door might be stuck.

03 Buick Rendezvous Overheating

If the top hose is hot and the bottom is cold, your definitely not getting circulation. You,ve already done alot of work to this vehicle so you have pretty much answered your own question. About the only thing left is the heater core. Of course, I dont want to be the one to tell you it is definitely the heater core because obviously I am not looking at the vehicle. But If i was a betting man, thats where my money would be.

My heater not working, i replaced thermostat and radiator hoses, had radiator flushed and rodded, and still no heat. What is wrong?

Too much blockage in heater hoses or heater core.
Bypass valve may be stuck on "bypass" .

1. Remove bypass "Tees", but don't discard.
Replace with straight-through hose fittings.
The core may start leaking under the water pressure since there is no bypass hose.

Once the heater starts working, put Tees back in place. You need bypass protection or the engine will overheat.
