You can safely blank the EGR pipe at the EGR cooler if you believe that the EGR cooler is leaking/bypassing. You do not need to remap the ECM but, an EGR delete is best so the code is not stored. The 4M50 engine is very prone to cooling issues. It is a solid engine and will last for a long time however, the cooling fan hub often sticks. You should be able to stop (wearing gloves) the fan from spinning when engine is cold and when engine is hot, watch the fan when shutting down. It should stop immediately and not run on. The EGR cooler is prone to internally leak. It is built very lightly and of thin metal. When the cooler corrodes inside, it will crack and cause exhaust to enter coolant side. The radiator/pressure cap is poorly seated on housing neck. You need to carefully measure/check distance of radiator cap sealing compression and housing depth. It helps to fold down the tabs of a pressure cap to get a better seal. If the pressure cap opens prematurely, the cooling system pressure will not hold and the coolant can boil. The head gasket is also something that gives up at around 150,000 kms. If you have CO2 in the coolant (at the pressure cap housing neck) it will be either the EGR cooler or head gasket.
I have the same make 4m50 engine Mitsubishi, but the problem is the revs are not going beyond 3 and taking long to respond to gears with an engine check light on. What could be the problem
@@MECHANICMANTutorials kahit ako ayaw ko sa mga mitsubishi, marupok ang cylinder head napaka dali mabingkong kapag nag overheat, isa pa kapag namatay sa overheat sigurado overhaul kana at nanikit na piston at ring
@@michaelmulto8013 bkt mo naman papaabutin mag overheat ang truck mo 😂😂😂 kht Isuzu pa yn at pabaya ka masisira yn . Wla aq kilala papabutin ap mag overheat ang truck
Hindi boss normal lang Ang temperature bago pa Ito boss mag dalawang taon palang Ito Basta lahat gumagana ng maayos pero Yong travel Niya pagdating ng isang oras humina na sa simula ok pa siya mag travel pagdating ng isang oras soon na siya humina.
try muna boss paandarin ng walang fan belt tapus buksan mo radyetor kailangan malamig pa ang ang makina.. kapag tahik ang tubig at walang bumubula ibig sabihin cooling system problema. kapag bumubula ang tubig.. check muna head gasket.. at cylinder head.
@@MECHANICMANTutorials wla nman sir putol na wire...san po ba sir location nyo po wala kasi makapag patino netong 4m50 ko po low power na hard starting pa..namamatay pa pag nalulubak
@@michaelmulto8013 siguro depende nlng s pag aalaga tlga kht sa isuzu nag ooverheat din tlga ksi s ngyon sa unit ng boss ko ung isang truck nag ooverheat lalo na pag hinahataw tumaas temperature.isuzu sya 4hl1-2 turbo
Boss bka sakaling mtulungan m ko ung truck ko kc na 4m51 canter mlata cya sa arangkada mula nung npalitan cya ng modulator ano po kya mgnda gwin dto kc nd cya kaagad umaarangkada delay kc ung galit nia..sna boss mtulungan m ko godbless...
