hi im from the philippines and the weather goes up to 95-100F everyday . i have a mercedes benz fintail 200 gas and my engine temp. goes up to 190-200F in traffic without airconditioning. Is this normal? i changed engine fan to a 6 blade flexifan, removed my thermostat and permanently covered my bypass using aluminum that i custom made so that water will circulate throught the radiator all the time. Is this right ? will it lower my engine temp. ? i installed a custom made fan shrud to maximize air flow to the radiator. i placed a elec.cooling fan if i use my airconditioning. i changed my radiator to 3 holes for more water capacity. but still my temperature goes up to almost 200F in traffic and without airconditioning. what more if i use it surely my temp will go higher . but if car moving steadily to 40-60 mph my temp is 160 F. or lower and my car runs better. i dont know but are older mercedes benz car designed and more suitable in colder countries ? Do u recommend using Mercedes benz coolant. will it not eat up my aluminum head? will it lower my engine temp. ? need help .
