Cooling method for GTP-750

Hi, I just came across this post and I just got a GTP-750 and I too notice that it runs extremely warm when left on for a while. And I am suprised that there are no cooling vents OR a fan used...right now I have the top cover open about a 1/4th of the way just to let some circulation happen.

What do you have for a cooling method and the rectifier info would be appreciated in case I need repair on this unit - mine works great still and I am hoping to not have to go through any repair anytime soon due to overheating!

Please email me at beenaice@yahoo.com. Thanks!

Well ehy do you not put in 2 fans. 1 on the left and 1 on the right. Make the vents and build it in. You can use the standard size PC cooling fan. Just look for a 12 or 15 V supply and make sure to regulate it with an LA7812 Transistor, Very easy circuit. Will give you one if needed.

    Hi, there is no big need for all that trouble. Why put in 2 PC fans if you could change you Heat sink. You need to look at the design of the amp and how it was made to run. Then look at your setup and see if this matches. If you are running more speakers or your load is more or less on that particular output then you should remember that you are not running the amp as it intended design.

    You can how ever change the amp to suit your needs.

    To cool it down first change your heat sink. Then ad a single fan on the top or back of the heat sink. make sure that you turn the fan around to create a vacuum. This will draw the hot air out and cool air in. Putting the fan at the back will be better as you will create air flow over and through the heat sink.

    Now: To run the fan yes you need a supply. between 13-18VDC
    Please do not use a LA7812 as this is a negative regulator. Use the LA7912. Make sure you use your power supply earth and NOT the amp's earth as they are 95% of the times Isolated.

    Hope you come right

Hi is it normal that the middle Paleo that the doors close onto seems really hot? We have an American style fridge freezer, everything else seems ok, but I have never noticed it before!! Thank you


Again a similar post as my last. This is normal unless the refrigerator is not cooling properly. There is a pipe that goes around the door that carries hot Freon to keep the doors from sweating where the cold inside meets the warm air outside. This area will become extremely hot should the airflow below the refrigerator become obstructed or the condenser fan below the refrigerator not be working properly

I have a 2005 Buick rendezvous that has had a radiator cap and radiator water pump intake gasket flushed radiator why is it still running hot


Being it appears from your post the intake gasket was changed (I'm hoping it was the lower intake gasket) then I would suspect the thermostat.

IF the thermostat was changed then another, and pretty common cause can be an 'air lock' in the cooling system.

There should be 2 bleeder valves or screws located on the engine.
One should be on the thermostat housing and the other should be located above the water pump.

There are a couple of different methods of bleeding the air from the system. One is to do it while the engine isn't running, the other is while the engine is running and starting to get warm.

Both methods can work and I've used both.

The method with the engine not running I usually use while I'm refilling the cooling system after I've made repairs.

The method with the engine running is the one I've used if there have been previous repairs done but the engine still overheats or the heater/defroster doesn't put out any heat, even though the temperature gauge says the engine is warm or getting hot.

IF THE ENGINE RUNNING METHOD IS USED CAUTION IS THE WORD OF THE DAY AS THE STEAM AND COOLANT COMING FROM THE BLEEDER(S) CAN BURN YOU!!

Hopefully this video will show you where the bleeders are located.
Hope this helps.

Why is my sub zero fridge model 590 warming up?


Hi fridges will warm up on the outside as they remove heat from the inside. excessive heat with not extreme cooling inside the fridge indicates a possible degridation of coolant fluid or a leak. as the motor tries to cool the fridge the thermostat inside stays on as the tempreture inside has not been reached. if you hear the motor/ pump continually running this will indicate a cooling problem.

Lifter noise


Wrong oil. Check the engine temp and thermo. Make sure oil is compatible with service. eg. your driving style and the weather. Castrol is pretty good oil. I used it in air cooled motocycle engine to solve shifting problem in hot weather. All lifters do not get the same cooling. That one is prob running a bit warm. good luck with that.

Got a suzuki gsxr srad 2000 model went out for a ride today since i brought the bike 2 weeks ago and i let her warm up with the choke up must of forgot to put it back down for the ride and now it wont...


Around 2000 was the first year for fuel injection for the GSXR 750. It really isn't a 'choke' in the true sense of the word. It's a device that causes a high idle similar to an 'enrichener circuit' to warm up the bike engine. There should be no damage to the engine by leaving it on for a short ride so I'm thinking there was an unlerlying issue with the bike that the previous owner left undisclosed.

Around 2003 that device was abandoned due to the advancement of technology in fuel injection and was no longer needed.

After typing this response I just noticed the original post date was in 2012 and I'm sure the bike has been either repaired, sold or crashed by now but maybe this answer will be helpful to someone else.....

My GTP runs 15 mins and looses fuel pressure.. Fuel pump is new


Heres what you need to do to start with. If you are mechanically inclined, when it stalls, check for spark on the #1 cylinder. If you have no spark there, it is likely the CPS or Crankshaft Position Sensor has gone bad, a common issue, and will need to be replaced.

If you need any further help, there is an online Grand Prix community you can check out at http://www.grandprixforums.net. Sign up there and post up your issue and you will get some more input.

Whirlpool ultraease warm on left side, dispenses warm water


not dangerous, i would recommend vacuuming coils under and behind refrig, make sure the fan behind the unit( cooling for compressor) is running full speed. the water is probably "warmer" then usual because the waterline runs across the bottom of the refrig, which appears to be overheating as it is. this should rectify your issue

I hope your Fridge is still running okay. I saw your post and your description sounded the same as mine 2 weeks ago. Now my fridge is not cooling much at all. Turns out the defrost heater isn't working. Hopefully I can find out why before a repair man takes me for $100's.
