    With laminar coolant flow the relatively cooler and hotter coolant will not mix well inside the radiator decreasing the heat exchange.

    I think if one will not use rust/corrosion/deposits/ preventative products pwede nga bumara yung coolant flow.

    You give up about 1 HP for every 25 amps of alternator output. Yung pang off-road namin meron ding manually controlled auxillry fan at double switch din ang mga headlights.

    Test mo muna, i-rev mo mga 1500 RPM car mo without any fan rotating, dapat aandar fan mo before the redline, but be sure within specs pa thermoswitch mo.

    Or di kaya restricted yung exhaust mo or masyado lean ang fuel mix mo kaya ganyan behavior car mo when going uphill.
    suspect ko na stuck open yung tstat kasi ang tagal bago umabot sa normal operating temp. at saka minsan pag mabilis na downhill nagover cooling, below 1/4.

    will check the fans. original thermoswitch ang pinalit ko. engine and exhaust is stock. EFI so ECU controlled ang AF mixture.

    i checked one sparkplug. medyo worn na, may connection kaya ito?
