SOURCE: I have a 2008 KX450F.

There is no reason for the idle to take 10-15 seconds to slow to normal. perhaps you have a vacume leak. check all your seal and gaskets between the engine and the carb.also when it is running spray gummout spray or equivilent around the gasket edges between the engine and the carb, if the idle increases when you spray then you have a vacume leak. (intake leak). It may be that this is causing it to be hard to start when it is hot.(not getting enough fuel)

Truck is overheating and have already replaced the thermastat


Here are 10 tips to address with any overheating problem:

1. Many cars overheat from more than one problem. Often we assume a bigger radiator or a similar big gun solution will fix our problem. Maybe it will, but often by so doing you are addressing the symptom and not the cause. Many cars over the years pick up little annoyances that contribute to overheating. Individually none of them would overheat your car. Collectively you have an overheating problem. Look at the whole car when addressing overheating problems.

2. Before you do anything else, tune up the car. Many overheating cars are out of tune, Be dead nuts certain you are not running lean or with retarded timing.
A lean fuel mixture will overheat your car right now. If your engine runs lean you can chase your tail looking for problems in the cooling system and never figure it out. Be sure you are not running lean. The easy way to do this is richen your jetting a couple of steps. If the overheating is better, you're on the right track.

3. There is a lot of misinformation about ignition timing and cooling. Retarded timing contributes to overheating. Advanced timing helps cooling. Bump up your initial timing a few degrees and see if it helps the car run cooler. It's an easy and practical fix. Of course, if you advance enough to enter pre-ignition or detonation you will start to overheat. Detonation contributes to overheating. If you start to detonate back off the timing. Overheating cars should always run vacuum advance. Vacuum advance helps cooling.

4. Cars can overheat from coolant circulation that is either too slow or too fast. When your car left the factory it probably had the correct speed for the water pump. Over the years things change, pulleys are swapped, rear end ratios are changed, tire sizes vary. Your car may not have the right circulation speed for the water pump. Remember cars can overheat from circulation that is either too fast or too slow.

5. Look at your airflow. Be sure your shroud fits properly and is sealed to the radiator. What'd ya mean you don't have a fan shroud??!!?? If not, obtain a shroud before you do anything else. You can adapt a shroud from the junkyard or many after market suppliers can provide you one. Seal the shroud to the radiator with weather stripping.

6. The best all around fan is the factory design with a thermal fan clutch. Flex fans aren't as versatile, Solid fans pull lots of air but are noisy and suck horsepower when you don't need the extra cooling.
If you need extra air flow there are many electric fans on the market that can help. Be sure your charging system is up to the task of handling the extras amps from an electric fan.

7. Reduce the antifreeze in your coolant. A 50/50 mixture does not help cooling. Either run 100% distilled water with water pump lubricant or distilled water with about 15-20 % antifreeze. Either mixture will cool better than 50/50 and still lubricate the water pump and provide corrosion protection for your system. Remember when the weather turns cool to switch back to 50/50.

8. Use a better grade of gas. If you are not running premium and you are overheating, step up to the top grade. If there is no improvement, try advancing your timing a few degrees. The extra octane will allow you a little extra timing without getting into detonation. Many older cars and particular muscle cars were designed for better gas (4 or 5 star, > 98 octane) than is now available. If you are detonating on today's gas you can be overheating. Remember not all detonation is audible.

9. If you are running an automatic, install a quality after market transmission cooler. Cooling the transmission is added work for an already overtaxed radiator. Do not mount the cooler in front of the radiator where it will overheat the cooling air. Rather mount it to one side.

10. Notice your driving habits. The more gas you burn the more heat the engine produces. Jackrabbit starts followed by hard braking, constant acceleration, flogging the engine uphill, all burn lots of gas. Yes, these are performance cars and that's why we love them. We're not saying don't enjoy your car, but if you are constantly into the accelerator, you are producing extra heat that the cooling system has to get rid of.

Compared to the expense of buying parts in a hit and miss fashion to solve your problem, investing in researching the origin of the issue is a downright good investment.

Transmission is due for a rebuild

Stop using it --- as it will only overheat more
& ruin hard parts inside it

There is no fix for slipping

When car picks up speed the heat blows. when u stop or slow down. cold air blows


Tell me when you speed up is the heater set on hot and high speed?????
WHEN you slow down is the fan still going at the same speed or dose it go very slow when on idle.
If the Fan stays on high but runs cold when going about 80 in top but when you speed up it gets hot and then back off slightly then its sounds like Water pump isent pumping the water around the engine correctly ,but then it should make the engine run overheated.or it could be a slipping fanbelt, but then that should make the Alternator to make a noise,so {throttle to 2000 rpm from idle standind still} and see if there's a noise coming from the water pump area.
The belt should have just a little free movement more on the longest part of the belt(a very little about 1/8' movement
So check it out and let ne know how you get on .

90 legacy, started overheating but was blowing cool air out of the heater even as the needle was pegged. Some fluid in reservoir, top radiator hose felt like it was under a lot of pressure.


Two things would cause this

There is a slow leak and the radiator is low on fluid

Let the vehicle cool down completely and then check the level in the radiator. I bet its pretty low. Top off the radiator with a 50/50 mix of coolant and water. start the vehicle and let it warm up with out the radiator cap on. Keep adding fluid as necessary. While waiting for it to warm up check around for any abvious coolant leaks. Things like hoses, radiator seams, water pump, water inlet/outlet gaskets. If no leaks are found it may be necessary to pressure test the cooling system and even then it might be a slow leak that only occurs when the vehicle is cold.

If the radiator is full than I would suspect that water pump is no longer working or creating enough flow. If the thermostat where stuck you would still get heat. If the water pump is not circulating coolant than you would get no heat and the car would overheat.

Classic signs of a bad water pump. When on the freeway, the circulation of coolant through the system is increased due to the speed but once you slow down, it will tend to overheat. Please post back with any other questions or just to rate the solution. Thanks very much!

Does your Pegaso Overheat?


meaning that they all overheat. just want to check with you guys if it happens to you too. thx Only in slow heavy traffic (or at very slow speed AND in very hot weather) but if the fan works alright do not worry. It should get cooler as soon as you start riding normally again, i.e. around 20/30 mph. ,,,
