Toyota Revo SR 2000 (1.8 - Gas M/T) - Overheating Problem

[Dusty]

Vehicle: Toyota Revo SR 2000 (1.8 - Gas M/T)

Good pm mga sirs.. Yung Revo namin kapag medyo matindi ang traffic mabilis umangat ang temperature.. So far aside sa malakas magbawas ng tubig kapag ginagamit, wala naman leaks na nakita.. Many times na pinatingin sa mga radiator shops para macheck kung may bara or anuman.. In view ng mga namention ko, I just would like to ask the ff:

a. Ano yung mga possible cause na naoverlook ng mga tumingin na Radiator Shops?
b. May marerecommend po ba kayo sa QC area?
c. How much ang estimated cost?
d. Do we have to replace yung Radiator?
e. Yung SERVO (tama nga ba spelling), pwede bang maging culprit?

BTW, pinalitan na noon yung Radiator (Yellowish ang color, not sure kung Brass ito or anuman) and now lang lumabas yung ganitong problem ng Revo..

So sorry for asking too much..

TIA..

Try to use coolant,if nag babawas maybe merong leak at since tubig gamit mo pwedeng na tutuyo na kagad kaya di mo na papansin,also try to check your clutch fan.

Depends. Radiator itself is not always the culprit. Kapag walang visible leak, rule out na ang water pump. Pwede ang radiator hoses, radiator cap, radiator fan or thermostat valve. Kung halata mo na umiinit lang siya kapag nakabukas ang aircon mo, baka naghigh pressure na ang compressor mo kaya malaking drag sa makina causing the overheat. Kapag sure na walang problema ang radiator, ang kanyang peripherals at ang A/C, tsaka mo na ichecheck ang head gasket for possible overhaul.

QC area ako, at sumakit din ang ulo ko dahil sa overheating ng Revo namin (replace head gasket). Suki ko ang A1 sa may Del Monte corner D. Tuazon, Class A sa may Retiro corner Biak na Bato, and Wilson & Jackson sa may D. Tuazon corner Dapitan, preference in that order.

normally, modern cooling systems remain full for months on end..
if yours does not, then either you have a leak somewhere, or you are overheating.

coolant prevents rusting or oxidation of the metals in contact with the coolant, thus helping maintain the cooling ability of the cooling system..
but it does not directly prevent overheating. in fact, it lowers a teeny bit, the heat-carrying ability per unit volume, compared to plain water.
