We had my son's water pump replaced in his 97 F150. It is now occasionally jumping to completely hot. If you turn it off and back on it returns to normal. The power to the engine is cut when it shows to be overheating. The check engine light has now come on.
View 9 RepliesI have a 76 f250/460 engine. I have replaced the hoses, belts, water pump, fan clutch, flowed the radiator and it still overheats.
View 4 RepliesMy son has a 2002 Jetta, we just changed the water pump and the thermostat. The car will sit at idle and the temperature will stay around 190. When you drive down the road the temerature will rise and when you let off teh gas the temperature goes back down. What this could be, I have tried everything I can think of to fix this car.
View 13 RepliesI bought a 2003 Pontiac Grand Am a month ago, I have already replaced the power steering pump, the water pump, plugs and wires, new battery. It was running fine I drove it last night, but the radio has said loc since I bought it. Then today I got in it and tried to start it and it won't start. It turns over like it is going to start but doesn't. I tried the 10 minute reset thing. That didn't work.
View 1 RepliesIs it common to have to shim the water pump pulley? I don't know why but mine seems to have moved back a fraction of an inch. I loosen the belt tension and slide the belt back and as soon as I start the motor, the belt slides forward again. And as I rev the motor, the belt moves even further out onto the edge of the water pump pulley and starts to squeal. All other pulleys are aligned and the belt spins fine on them. I thought about buying a shim kit, but I ordered a new Motorcraft water pump since I have 154k miles on my truck.
View 7 RepliesIs there any benefit to adding water pump lube to a 4.6L engine? There's smelly, old looking coolant in my friend's "new" 1997 F-150 so a flush is in the immediate future. I'm going to suggest using G-05 coolant over conventional green due to its longer life. Should water pump lube be added?
View 10 RepliesI bought this truck an it ran good then one day it started knocking really bad so i replaced the crank shaft an bearings. Put everything back together started the truck an it ran like crap an i just happened to check the oil an it is milky. All the water in y radiator is now in the motor oil an truck has no power...
View 2 RepliesOk so I have a 2002 f-150 4.2. I was replacing the PCV elbow that always crack and I figured while I'm down here, I might as well replace the PCV valve as well. I have the PCV valve that has 3 connections, 1 to the crankcase and then 2 "vacuum" type connections connected to the water pump and is full of coolant of course. What am I missing here, I though sometimes these things were connected to a vacuum line, is this some kind of heater for the PCV?
View 12 Repliesthe only thing that is left to replace would be the radiator?my truck is a 1994 f150 and it is not overheating!i get lukewarm heat only on the highway,everywhere else it is cold air!!this new england weather is killing me
View 10 Replieshave a 2006 f250 with the 6.0 Powerstroke diesel started overheating yesterday the ECT and EOTcheck fine with the scangauge always ran with in 8 degree's of each other. Thought maybe water pump impeller may have been slipping so it is new with no change. Fan kicks on like it should. Heater works good so don't think it is a thermostat.
View 13 Repliesi just did a new timing belt water pump kit on a 2001 1.8t (aug engine code) the new pump has a metal impeller. i ran it in the drive way for mots of an hour off and on. figured it was good. took it for a drive and at 5 miles it overheated. Temp Went straight to 260 and stop light came on. coolant could be heard boiling in the system. when i let it idle and ran the heater i got the temp to go back down to 190. but after idling for couple minutes it started going back up. I don't think the stat is bad considering that the heater works which shows that the system is flowing.
View 5 RepliesI replaced a water pump on a customers 2013 5.0L truck this week. The bearing was totally shot and lost all the coolant. Truck only had 46000 miles on it, is this common?
View 7 RepliesBought this truck at auction a few days ago. Started drive home and noticed temp gauge almost pegged full hot. Stopped and left it and pickup up later that day with trailer. Got home and started and ran it. Will not overheat at idle. Gauge fluctuates between full cold and 1/2 at idle. Rev up and temp drops to full cold. Drive around town under 35 and it stays between 1/2 and 3/4. Get on the highway and Pegs full hot. Replace thermostat and flushed system. Lots of rusty water and chunks of rust/mud poured out.
Upper rad hose is firm and hot. Lower rad hose is warm soft. Bypassed heater core and still over heats. I can run water hose from top hole on radiator and water crosses threw radiator and pours out the bottom so I don't think it's clogged. It's not the head gasket, I have no smoke, no milky oil and no oil in coolant. Fan clutch seems fine, I can spin it with the engine off and feel resistance. Truck hasnt boiled over while running hot so the gauge may be wrong. If it means anything the truck runs very rough and pulled up a misfire on cylinder #1 and had a iac code.
Ok, I just bought myself some problems in the form of a '93 Celica GTS. (5S-FE)
Well, alright, that's a little dramatic. it just overheats. but here's my issue. it's got a new water pump, new radiator, and is still overheating. The guy I bought from says it's in the block, cuased by an attempt to plug a radiator leak with stop leak. He said it just had a minor leak in the radiator, so he put stop leak in it, and after that it started overheating. he's replaced the thermostat, water pump, and radiator since then.
My first question is, could he (and I) be overlooking something? could there be a clog somewhere easier to access? and then if there isn't, how should I go about cleaning out the block? are there areas I should check? anything I should do to try to unclog it? my current plan is to put cooling system flush in (he has some) and drive it home (about 55min. drive) with the flush in it, then empty it and hope for the best.
1995 Isuzu Rodeo. Replaced water pump, thermostat, timing belt & components. Now it over heats & no heat in cab. I was told to "burp" the cooling system but can't find the bleed valve. Is there even one on the V6 engine???
View 3 RepliesI just replaced the timing chain and water pump on my 1999 K1500 5.7L. After spending several evenings and a few early mornings working on it, I get everything back together and go to start it up. It starts then immediately dies. After double checking that the CKP sensor, two plugs on breather, and a/c and alternator wires (these are all that I unplugged) are connected I try in one more time before coming in to work today.
Timing chain was installed with No. 1 at TDC and mark on cam at 12 o'clock position as stated in the Haynes manual for the truck. I did not remove or even touch the distributor since replacing the intake gaskets ~3 years ago. Will check to see if any codes are showing in the morning when I have my laptop at home.
My brother has a '92 K1500 5.7L in which he had a leaking water pump. He replaced it with an Autozone unit. After replacing the pump, he now states he is experiencing fluctuating temperatures on the gauge. He has little heat at the heater, even after letting the truck idle and after driving it. This was not a problem prior to replacing the water pump. He has put approximately 200 miles on since the replacement and it has been about 2 weeks since he replaced it. He believes he has all the air out of the system, as he has checked the overflow container and radiator several times and the coolant level has not gone down.
This now "suddenly" appears after the pump replacement, we are thinking it is not the temperature gauge sensor or bad thermostat. We are thinking possibly still air in the system or water pump cavitation.
Four cylinder, 2004 Camry (2AZ-Fe), Auto with 98,000 miles.
I had to replace my water pump after driving with newly replaced Toyota Red antifreeze from the 8 year old Pink. I drove only two weeks and 1000 miles on it.
I believe that was just a coincidence. Some Camry's water pumps do not last even that long. Even if the coolant was not compatible with Toyota specification, it still could not destroy the pump seals in two weeks.
My aux water pump was acting up and started leaking a year or two ago. I replaced it and it seemed to be doing fine. Recently it has started buzzing very loudly right when I turn the car off and keeps buzzing loudly for a few minutes (5-10) after the car is shut down. I know that is when it is supposed to be running, but why would it be so loud? Is it being over-heated or something?
View 1 RepliesMy girlfriend has a jetta and I work at a DODGE dealership in service. I recently replaced the water pump and flushed the coolant twice and replaced the coolant with G13 coolant from the local VW dealership. After I finished burping the coolant system of air bubble. After I finished I took it for a spin and being the speed demon I am, I don't hold back on the throttle. I noticed immediately the engine lagging and being extremely sluggish. I ran my shops snap on code scanner on it and I came up with cylinder 1 fuel injector open circuit. Cylinder 6 fuel injector limited power. And last but not least o2 sensor 1 open circuit. If your facing the motor I undid the left motor mount from the frame, lifted the car on a hoist and took the bottom side motor mount off of the motor. I took the cv shaft off of the transmission and lowered the car and jacked the motor up by the oil pan to expose the water pump for removal and replacement. I'm wondering if possibly the o2 sensor could cause the ECU to seize power to two of the cylinders to ensure no engine damage or if its 3 separate problems.
View 3 RepliesToyota dealer said computer indicated the water pump and belt needed replacing. We decided to do the replacement ourself. Now the light comes on which indicates car is running hot. We did replace the coolant. The 2005 Toyota Prius never ran hot before the replacement, What did we do wrong?
