Sorry I am not well versed with car issue. This morning when I went to work, I had to stop by roadside to pickup a work call. My car suddenly blew warm air and the temperature spiked to one bar below the highest. Thinking its just fan issue, I continue driving as usual straight to workshop since its not far away but the aircond did not improve. Went to workshop to change the radiator hose since its leaking as per my foreman suggestion and when he tried to put water into the radiator opening, he said it was coughing up water, meaning some part of the engine was already bend (casket bengkok/putus). He said my fan is working fine. Does this mean I need an engine overhaul? Car is already 10+ years. Saga flx.

If Foreman confirm can try top overhaul first , and other costs like timing belt, timings belt bearing/hydraulic tensioner, water pump, etc , if after removing the cylinder head worst than that then probably need full rebuild , but first thing is needed is to remove the cylinder head and see the condition only decide the later on solution.

possibly the water pump jammed
usually after overheat event, try to change the gasket. otherwise could leak coolant into combustion.

Since when yr car has casket (keranda). Is it kereta keranda hantar org mati or "gasket".

Not well versed in car lo. Kereta keranda still kereta what.

Yeah my foreman dint wanna do it, surprisingly majority car workshops in Keningau, Sabah dont wanna handle proton car, if perodua they are willing. Talked to some of my friends, they say check dulu. If the oil doesnt leak into the radiator just topped up coolant and overall head condition is ok see how it goes before deciding overhaul. Because there isnt any overheating signal from my car.

U got two problems..
One is with aicond system and another is your engine overheated and probably warped or gasket broke.

hmm means have to consider this too. The advices most of them given are if the oil leak into radiator usually have to change the whole thing. If no leaking can try top up coolant and see how it goes. Would change the gasket too tbh since the oil leaking have been quite severe but still in proper level even after months/years.

Its not so simple as to change the gasket only. Your cyclinder head might be wrapped and changing the gasket wont help. It might seal awhile if lucky not warp so much, but it will come again. When open up, the mechanic will check the head levelness to see if its wrapped. Hopefully its still ok.

Just serviced my aircond last month. Hopefully its not another aircond system issue.

Assuming the worst case scenario, how much the repair would cost me?

Overheating can be causing by gasket failure , is not entirely cooling system failure causing overheating, during combustion either gas leak to radiator more heat, more bubbling, more air no longer effective lubrication and cooling or worst case scenario the leak become overwhelming can causing water hammer inside combustion chamber either the piston rod make it all the way out to engine block, piston crack, vavle bend etc etc the cost is much more than top overhaul.

Very long time i no longer in Foreman Field but top overhaul last time labor+gasket only cost you rm 150 for wira era, so i don't know what the market price now, remove cylinder head, replace new gasket, slap in and good to go because your case probably not due to overheating and causing head gasket failure

This rm 150 not including timing belt, water pump, valve polishing, valve seal replacement, head surface triming, cam head oil seal etc replacement assuming all this part is still new and good condition

Check fan, water storage, water pump, coolant...

Let mechanic do a thorough check

In my situation, the engine overheated due to a jammed water pump and thermostat. At the workshop, the head was confirmed warped and requires a replacement.

After this fiasco, the always change the water pump and thermostat every 2-3 years regardless overheating or not.

Worse case scenario ah.. change engine and overhaul whole aircond system. 5k?
But this is most unlikely la.

Man wish my car issue was in your era. They quoted for top overhaul is at most 2k. But if what you said happened to my car eg: bending or cracking, a full overhaul of engine is needed and its 4k.

How much was the total cost?

probably you can ask what is included within this rm 2k ? item like head gasket, head, cover gasket, copper spark plug, camshaft oil seal, timing belt set, water pump, long life coolant, crankshaft oil seal, valve seal , valve polishing , valve lash adjustment , engine oil/filter change , resurface cylinder head?

cough up water = piston push combustion exzos until coolant radiator there. confirm leak

tapi bend ? pijak high rpm got unusual loud noise or not
