Cooling System: Water Pump Failure Symptoms

[StockEngine]

Notes:

1. Temp doesnt go up when its partially working. Temp goes north when pump dies.
2. Fuel consumption goes up considerably.
3. Throttle response isnt good- delayed power.
4. Transmission seems jerky.
5. If you start the engine again, tacho goes low-ecu senses hot engine?
6. A/C isnt as strong
7. Failure was imminent at 250,000km
8. Top radiator hose is warmer significantly than the bottom hose
9. Main failure: bearing siezed
10. Computer readout: overheat even before waterpump failed.

When you loose majority of your coolant.

if the pump fails completely, then yes

in some cars, the water pump leaks because of its age..
although strictly not water pump failure, it does lead to engine overheat due to coolant loss.
and if this leak is hidden from view, it makes trouble-shooting so much more difficult.

In our Mazda3, the A/C just stopped cooling. Like it was a switch turning off, it just stopped in the middle of driving. That's was like 10-15 mins before the temp gauge started to climb up... then there will be a point when it will just drop (no, it ain't suddenly cool...but you're probably not far from really big trouble.) Good thing I was already in front of Camp Aguinaldo, so all I had to do was turn around and park quickly * Mazda Greenhills. A new waterpump later, all is well again.

It's an 05...so, around 12 1/2 years old when it happened last year.

Experienced a water pump failure on a non ecu equipped car. So gauge lang ng temp ang basehan.

Kapag naka stop, dun tumataas ang temp. Had to stop every 5 mins to refill the radiator with water. Definitely stressful. Buti nangyari sya nang gabi at less ang traffic.

replace talaga dapat before complete failure. if that coolant level changes and the accumulated mileage is high then its time to replace that not so expensive waterpump. 2500 lng for my daily.

May isang member dito na naka sorento.. over heating din ang problem. Changed water pump din kasi ubos na yung impeller ng pump.

Kaya naman DIY yan water pump. Mga 4 to 5 bolts lang naman tatangalin plus belt.

temp warning light bro. sobrang weird kasi 98c (sometimes less)

eto pala ang kwento bro lol

Radiator / Overheating Problem

update again ..
AC off ..
confirmed automatic fan turns ON * 95c
but seems too late as by 96c, temp warning light turns ON already.

How are you reading the 96°C? That's still normal operating temp.

106-110°C is borderline and above 110°C can be considered overheating.

So it's either the measured temp is wrong or it's an instrumentation problem.
