Problem Description and Possible Solution
Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.

Engine overheats, noticed coolant leaking around the water pump area, I am fairly sure I need to replace the water pump and gasket, I feel there also may be a problem in the flow of coolant though the engine and associated hoses, as I put in new coolant in the resevoir and it is still a very bright green color and the coolant that is leaking is a dirty brown color, was wondering why this is.
SMALL COOLANT LEAK BUT TRUCK HAS NEVER OVERHEATED. I HAVE NOT TRACED THE LEAK TO THE POINT OF ORIGIN YET BUT IT SEEMS TO BE AT OR AROUND THE WATER PUMP. HAVE REPLACED THE WP GASKET ONCE, ABOUT 30,000 MILES AGO.
overheating only in cool weather. and a coolant leak from radiator front right side which is the same spot four of my friends are leaking from. put three jars of stop leak to no avail.
Not fixed yet. Overheating badly. Steam vigorously rising from grill after less than 5 miles of town driving.
Just starting to have coolent problems. Over flow leeks antifreeze, notice antifreeze wet when I left the hood. Don't know where it's coming from. Do know it's costing me money trying to find the problems
My truck overheated after driving about 6 miles on the highway at between 50 and 65 miles an hour. I pulled off and stopped, added some coolant but it was not very low, less than half a gallon. Had it towed to repair shop. They replaced the thermostat and water pump ( $630.00) and a week later it overheated again. Towed back to the same shop, they said a loose bolt on water pump and some loose hoses, fixed no charge. Took it home (less than 1 mile) and the next morning engine check light came on. I took it right back and they said it was ok to drive, it was an emissions problem. I left and within 1/2 mile all the engine lights came on and the temp gauge went red. They said bring it back. I did and now they said it has exhaust in the coolant and needs a head gasket or a new head or block ( not sure which word they used) but it will be between $1500 and $2500 and I can't afford to fix it right now so it is sitting in the driveway and they don't think the repairs they did had anything to do with the current problem even though the overheating is usually the cause of the head damage. They are trying to say it was an preexsisting problem.
Replaced radiator, thermostat, no water leaking but still overheating. Replacing fill neck cap and coolant temprature relay and the thermostat sending unit or ect relay.
INTAKE LEAKS IN OF ENGINE.
The dealership replaced the water pump and it has not stop leaking from the top
Engine running hot (220) if outside temp is above 85 degrees. Can not run a/c without overheating the engine. Have replaced heads, water pump, and thermostat (3) and problem still there every summer.
Coolant leak for years had it fixed 3 times still leaks
Heater return hose keeps blowing off
Vehicle did not run hot or show a check engine light. intermittant scent of antifreeze. No coolant in overflow. Took to a radiator specialist who noted a crack between the overflow tank and the radiator. Had to replace the entire radiator and overflow to correct the problem. Also, was told the entire "guts" of the radiator was "bad." It has been two years and still get occassional scent of antifreeze, no coolant in overflow. Suspect heater coil.
Knocking sound when it's starting to overheat. Engine will die once you come to a stop.
water pump went on a drive to pa... wierd symptom that I didn't really understand..it was overheating it was just stalling when when I'd brake aggressively or drive too slow.... anyways the water pump made it stop. not related but I also just found a transmission leak. damn...
Water pump was bad leaking fluid.
coolant leak intake maniford
I have the 5.9L V8 piece of c*%p, and yes it leaks coolant to the point of blowing the head-gasket. I have 144K miles and have owned for last 13 yrs. Faced with trade in value of 3500 to 4000 which with 6K for an engine install means I can buy someone's used problem for a total of 9500 or just go the 6k and enjoy a new remanufatured engine. Hum.........
The O-ring on the water-pump return from the heater core. Easily identified where the leak was coming from and replaced it.
Just replaced the water pump for the 3rd time and installed a new radiator hose. No other leaks spotted. First time it's been driven over 20 miles in one stretch since it was fixed 2 weeks ago, and it runs hot again.
