Hai guise..

to the campro users here, just wanna ask a quick question? has anyone's car overheated before?

yesterday, i checked my coolant, which was full. reservoir was half full. drove to rawang and back. this morning i checked, my coolant disappeared. weird? there is no leaks (as far as what i can tell), gasket leaking? theres no trace of oil in the radiator.. what other possible causes?

u might want to give a check on your water pump..

ps: i hope u never skimmed your car head before.

Water pump? Will have it checked.

Skimmed? I dont think it was skimmed before

i'm facing the same problem as you before , send my car to workshop .. they said it caused by water pump.. my water pump fins got stuck.

change the water pump + timing belt .. then everything goes normal back.

ps: the problem might be vary ,

but the ground is dry

yeah . the ground dry. same as mine. check for a leak , got no findings. then i remembered , i never changed the water pump since i bought the car late dec 2005. till 2012..

Mine 2009 cars worr

Collision before ma. U sure all parts are in good conditon after repair.

Happened damn recently only leh.

Ya i know, summore still stubborn drive to rawang.

I mean the collision may have shorten the lifespan of the part, even if your car still young. For example a component crack sikit sebab coliision, then over next to years the crack become bigger then kong lor.

just go to workshop do pressure test can know really leak anot. sometimes small leak you wont able to see it. small leak will be vaporized leh

Where are you now?

OK, based on what I've experienced before:

1. Check if you reservoir is full when your radiator is empty. If there's a clog somewhere or your radiator is overheating, water will tend to pool in the reservoir tank. Could mean the water pump, the thermostat or clogged tubes.

2. Check if the radiator tubes are rubbing against any metal parts. The create minor tears in the tubes which will not be visible when the coolant is cool. Water will only start leaking when everything gets hot. Drive around until the radiator fan kicks in (which means the system is already hot) then look for water leaking anywhere. That's how I spotted mine

Hope the tips help

Pour in coolant if you don't use any, coolant dries with white residue making it super easy to see any leaks

I assume coolant disappeared meaning coolant loss. First thing you should do is flush it and then refill properly with coolant. By properly I mean there should be no air bubbles in the system. Clean up the spark plugs, rad cap, inlet & reservoir. Then use the car for a day. After that you can do your diagnosis.

Things to look for are:
- Color spread around the engine & rad coolant inlet. (hose/radiator leak, thermostat)
- Coolant level in the reservoir. It should be over max when hot, down to max when cold. (hose/radiator leak)
- Coolant shouldn't have faint petrol/exhaust smell in it. (gasket leak)
- Exhaust smoke shouldn't be white when hot. (gasket leak)
- Fan should be running properly. (fan motor, electrical)
- Coolant shouldn't jump out like spring when start the car at cold and rev it. (gasket leak)
- Coolant should be flowing out the inlet/through steadily when car is running. (water pump, electrical)

The cheapest stuff you can replace are:
- radiator cap
- thermostat
- fan motor

Problem was due to a problematic thermostat.

Thread will be left open for future discussions and easier reference. TQ

I think probably mine will be the thermostat as well ~_~

yeah, rest working fine, but the termostat wont open for cool water, then engine become hot...like crazy think what happen...but inside is the culprit.

most 2 thing culprit u cannot see any sign from outside...
1. water pump kong
2. thermostat kong

One of the best answers
