Replace fuel filter if it has not been done in a while. Also check fuel pump pressure with a gauge and compare with spec. When key is turned "on" the computer turns on fuel pump via relay. If the computer does not see rpm signal (engine start) within approx. 2 seconds it turns the fuel pump back off. Cycling the key often helps to build up fuel pressure sufficient to start when filter is plugged or pump pressure is weak.

I have a 1997 Toyota Avalon. I've been having overheating issues. I replaced the radiator,but am unsure about if my water pump. I cannot find a diagram of the engine showing me where it is located.


water pumps give very little trouble other than bearings and seal
look for other more likely problem areas such as
head gasket ---have a compression test done
thermostat---have it checked
if electric fan/s --check relay, fuses,coolant temperature sensor unit
if viscous fan --replace viscous fan hub

Fix an overheating buick rendezvous 2002. Truly overheated once, then had the radiator flushed and replaced, along with thermostat (twice) and water pump. Now, the computer indicates it is overheating


You have a needle in a haystack because so many things can cause your problem. I am leaning toward the main computer - which you can replace yourself for around $300. There are companies on the internet that will send you your pre-programmed computer, you have to supply your VIN number. Like many internet companies I always recommend that you are careful in your selection. Be careful to find a reliable company and call them on the phone to make sure they are a real company. If they do not have a phone number - find a different company.

Here are a couple things to try first:
1) Coolant sensor - but this usually makes your car run really poor because it can change the gas/air ratio. If your car is running great other than the overheating sensor - then this probably is not the problem. But worth checking.

2) Serpentine Belt - sometimes when you change the serpentine belt you can put it back on the pulleys out of order. Your car can run great but can cause overheating especially if you have the water pump turning backwards. Since you had the water pump changed you might just take a look at the belt to make sure it is wound correctly. There should be a sticker under the hood.

All said -- I am still leaning toward the main computer.

My 04 seabring is still overheating after replaceing the thermostat, and then wont start


If you have the 2.7L engine, you may have a bad water pump. The water pump is turned by the timing chain. When the water pump on those particular engines go out, tension on the chain goes away and retards the camshafts bad enough for it not wanting to start. Pull your oil dipstick out and see if you see signs of water in the oil. If there is, this is your problem. When the water pump goes out on those engines, it'll drain water straight into the front of the oil pan.

My 92 Ford Ranger 2WD 4 cylinder recently overheated. I pulled over and added water. Continued on, then it overheated again. After having it towed home, it will not start. It is turning over, just not...


When you added the water was the engine still hot? When you filled it, was the engine off, or running? Pouring cold water into an overheated engine, especially when the engine is not running, will crack the engine block-fatal. check for oil in coolant or coolant in the oil, check compression-if all are good, start checking for spark (ignition module) or fuel (sound of fuel pump when key is turned on)-good luck.

Engine overheating


The coolant flush on radiator doesn't do any good. Since you have changed all the key components and still gotten overheated, then the root cause of the problem is the radiator. It got clogged up in small tubes blocking coolant flow. No matter how good the water pump is working but the radiator got clogged up, coolant is not circulating therefore the heat from the engine can't be dissipated to the radiator. Replace your radiator, don't even think about rebuild it. It has been used for 11 years. Make sure to have the correct coolant/water ratio to keep radiator life for years. Good luck.

Overheating engine


Check your oil dipstick for coolant, or a mucky substance. Your symptoms sound like a blown head gasket.

I recently replaced my water pump. this afternoon my car overheated and radiator fluid was leaking above the water pump


Check your thermostat. It may be sticking and keeping the coolant from flowing, hence the overheating. Where above the water pump is it leaking? Hopefully you didn't blow a head gasket.
