I have a 2006 gmc with a 5.3 ltr engine, how much coolant does it take to fill it

LTR fuse #30 15amp , AUX PWR fuse #29 20amp . located in the under hood fuse box .

This is the reduced engine power light you need to have the vehicle put on a scanner to see what the malfunction is. Thanks Klay

cedricponce7, Your fan is connected to your water pump. If you can wiggle it then the bearings in the pump are bad. When the engine is cold open the radiator cap and see if there is any coolant in there. Chances are the radiator is very low. Fill the radiator with water and see if the bottom of the pump leaks. If it does then you have to replace the water pump. Drain the cooling system and refill with the proper coolant. Good luck with this.

i have mine at the dealer for the same problem, it turns out that the 5th cyclinder is misfiring. the dealer is paying for the repair as there is a service bulletin out on it. all i have to pay for is the oil change and new sparkplugs

not too bad of a job, pull the fan and dampner. ive heard of guys saying they can do it without pulling the dampner (i dont know how?) it doesnt take long to get it off. dont put a cheap w/p back in, if the shaft seal goes out you will have alot of coolant in the oil.

drain the radiator refill with water & use some radiator cleaner, you may need to repeat this several times to get all the oil out......hope this helps.....cheers

Replace the hose from the radiator to the reservoir.and make sure the reservoir is not leaking.

5 & 1/2 quart's to 6 quart's

Number one should be at the 5 o'clock position. Then the plugs should go 1-8-4-3-6-5-7-2 around the cap in a clockwise direction.

Limited slip.
