Hi all, have replace the coolant reservoir with the cap. Heater bypass not done as Carclick didn’t order the parts . Problems of coolant leaking still persist. Appreciate if anyone could recommend me honest and experience workshop in such issue.
I also encounter on slow cranking. It happens approx 1 out of 8 time.
Usually , the car will crank well but occasionally, will encounter slow and weak crank. It happens on both occasions when the engine is cold or warm. I have replace the sparks plug , recon starter motor and also the battery but problem still persists.
Appreciate if anyone who has encounter such problems before could provide any insight or solution.
were u the one who replaced a lot parts for your cooling system already? radiator, pump, hoses, clamps, pump, cap, head gasket... what car is this again?
check your eo again to see if it turned murky in color. use a torchlight to check near the engine bay area. and area below engine. i really suspect its a warped cylinder head. replacing a new head gasket will not solve coolant leakage when the cylinder head is warped. i really cannot think of other areas causing the leak since pretty much the rest of the parts have already been replaced.
since starter and batt is new, i can only narrowed it down to either charging system not working properly, poor electrical connection (check your batt contacts for corrosion first) and/or electrical leakage.
do you have a dashcam that continues filming when u car is parked? this could be causing the leakage. sometimes, a leakage at bulbs at the vanity mirror, foot n door area or glove compartment can cause the drainage.
are you able to see the voltage when you r driving? i used to have something that plugs into the lighter and shows the voltage. i am now using a bluetooth odb2 port connector, and i can view it on my phone.
on a straight road, drive at a constant speed and glace at your operating voltage. if it's > 12-13V, your charging system should be fine. anyting below that is a clear indication that somewhere in the charging system is faulty. ie connecting loose, alternator about to fail...
good luck.
