I usually pump 80m head. Now the pump only pushes to 40m head and pump case is to hot to touch

First let your vehicle warm up to operating temp. At idle usually takes about 30 mins or take a drive for about 5 to 10 mins. With caution check your heater hoses. Should be 2 hoses going into your fire wall. Be careful cause they might be hot. Make sure both hoses are hot by gently touching the hoses. If not thermostat by be stuck open or closed. If they are hot to touch then could be your blend door not opening from your heater core. Now if one hoses is hot and one is cold your heater core could be plugged up. Hope this helps

Most likely pump. Head gasket will usually put hot gases into the cooling system and will appear as bubbles in the cooling fluid container. It may also feed lubrication oil into the coolant. The coolant pump is driven by fan belts. Make sure you are not missing any belts.

A/T or MT? its toyota engine, read the wiki.

if A/t THAT CAN BE THE A/T OIL COOLER.

FLUSH THE COOLANT AND DRIVE 5MILES WITH ONLY WATER
Sorry caps on, ok , the oil can not come from the engine.
easy. as there is no easy path (besides cracked head or block)
the oil gallery is to head is only 0.050" yes i mike everything i touch.
you could bypass the oil cooler on the tranny.
you could send the oil in rad, put in med bottle and get it checked
for ATF or Engine oil.
if the A/T ATF is still pink ?then is the water test above pink>??? easy huh>
im sure jiffyboobs didnt to your car too , right?

keep in mind at start up the RAD pressure is 0
and hot 14psi
so the A./T pump can sure has H3LL push fluid to the rad.
and when hot , it can go the other way.
differential pressures.

AF in engine oil is easy with bad head gasket or warped head.
usually the Eng oil dont go to RAD unless real bad. super warped.
if spark tips are not soaked in oil, then good. or green.

the pure water trick will help.
help see color better. and not react with chems in AF.
do not leave water in overnight or day frigid temps or the block will crack.
like this. (not me, Florida bimbos)

Hi... you are going to have to do some more checking. After the engine is cooled down open the radiator cap, look for goo on the bottom of the cap. Look for oil or goo in the coolant.

What you PROBABLY have is a bad head gasket and the pressure is pushing the coolant out of the engine...

I wish I had better news...

Replace the thermostat sounds like it might be closed or sticking

Most likely a cracked head or block '
When engines overheat the heads warp and something has to give. Even with just one overheating incident the heads can warp. You say you changed the timing belt, I think you mean the belt that runs the alternator and water pump. Big difference there. You might be able to save the engine with a big overhaul by pulling the heads and having them boiled out and pressure tested for cracks. It is also possible that the engine blocked cracked in which case you are looking at about $2000.00 to replace the engine. Oil on the plugs usually means water in the oil and oil in the water. If all those things are going on it looks like a disaster.

• SOUNDS LIKE YOU NEED A HEAD JOB. CRACKED HEAD OR NEED A HEAD GASKET. CHECK YOUR ENGINE OIL IF IT HAS WATER IN IT OR IF WATER IS LEAKING OUT OF TAIL MUFFLER ITS A CRACKED HEAD. IF NOT ITS HEAD GASKET. ANOTHER THING WHICH COULD BE IS FIRST MAKE SURE THAT THE WATER PUMP IS NOT LEAKING WATER CUZ IF IT IS THEN IT WILL BE THAT. SOMETIMES RUNNING YOUR VEHICLE WITH A BROKE WATER PUMP HEATS UP ENGINE CAUSING HEADS TO CRACK WHEN FILLING WITH WATER BUT USUALLY THE HEAD GASKET GOES FIRST. HOPE THIS HELPS.

Does the vehicle overheat on the road? If it does and pushes big burps of coolant into the reserve tank then you could have a head gasket leak. Usually what happens with a head gasket leak is that the engine will often start and run normally but will soon start to push coolant out in a kind of foamy burp as the combustion gasses that accumulate in the engine block force their way out. You can have a small head gasket leak that allows combustion gasses to escape into the cooling system without getting coolant back into the engine and often the first symptoms of this kind of a leak is a motor that suddenly overheats, the heater quits blowing hot air and after a short while everything returns to normal for a day or so. As the leak worsens however it may keep pushing coolant out of the reserve tank with a cool or cold engine as the pressure builds to quickly for the reserve tank to handle it fully. Having said that if you have a perfectly good cooling system that is hot and take off the radiator cap it will spray blistering coolant coolant all over so never remove the cap from a warm or hot cooling system! Most additives won't stop a head gasket leak as there is just too much pressure for them to "stick" in the leak and they just get forced out of source of the leak. It's rare but you could have a water pump that's not circulating enough coolant around but usually you have different symptoms than this.

did you check if yourl ow beams. might be burn out that is usually the case if the high beams work that is usually the case if the high beams work take them off buy new ones and try them just make sure you dont touch the new ones with sweaty hands that migh mess them up

maybe radiator might be clogged , but what do u mean by hot? overheating? if that's the case posibly cracked head gasket , also check coolant level .
