olajay5: @Siena and other pros in d group,
Thank you guys for doing a very wonderful job on this group.

Please I use a Toyota Corolla 2008 model, 1.8ltr engine, auto drive. Presently I used the green coloured coolant only (ready mixed by manufactural) but my car does overheating whenever I am in slow moving traffic and the AC is on. (Nothing happen when d AC is off as well as when in a free flowing traffic). I have read through recommendations on this group and I have done everything but d issue still persist. My question is could the coolant type be reponsible for a car to overheat?

Please advise. Thanks!

Siena:

Please, when you say your engine's overheating, it would help if you give an indication as to there your temperature gauge sits.

Siena: When the aircon is switched on, engines are under more load. I'd be looking at your condenser fan. Does it come on, when you turn on your air conditioner?

olajay5:

I have checked d fan this morning. The car has only one fan that covers the engine, the radiator and the condenser. When I started the car, the fan did not start but as soon as I put on the AC, the fan started blowing. But I don't know what u mean by "condenser fan". Is it different from the general fan?.

Once again, thank you for your responses.

Siena:

If you're having to top up your cooling system even once a month...you've got a leak. If you're having to top it up daily, then you've got an even bigger leak. To sum it up, your engine's using coolant faster than it uses gasoline.

I used to maintain my mom's old Peugeot 504 GL, Ford Cortina XL and my dad's Plymouth Avenger DL. Never had to top up coolant even weekly, and these are old cars!

I would get that leak fixed.

Funjay: I use Corolla 2005, 1.8L and i have never had to use coolant b4. It has been water all along for me and almost all the cars around me and in my compound use water, i had to top up once in a month or so. Sienna, i will like to know, is this a knowledge gap problem or hw can we explain the preference for just water by most car owners? are some cars designed for water only? is their any long term implication of using just water?

I await your response.

mich2012: Hi Siena, I have this Honda Accord 05 I just got and the color of the coolant in the reservoir is Blue I think and below the minimum mark. I called my mechanic and he said I should put water in it, what's your advice?
Also, do I put coolant in the radiator or the reservoir which has this blue coolant I mentioned above?

Siena:

Your Honda's reservoir is an expansion tank only. So there's a thin hose leading from the radiator top area (by the filler cap) to the reservoir. So you want to check the level in the radiator itself.

If it's low, topping it up with plain water will dilute it, and make the mixture weak. So I would mix a 50/50 coolant solution (about a litre should do) to bring the radiator level up, so it's visible below the cap. It doesn't have to be right to the top.

akaymotus: Hello Siena, u re doing a gud job here sir....pls i got a lexus gs300 from UK about a year ago, i had to convert it from RHS to LHS, since the conversion i have always felt heat coming in & i was told its normal that its the engine's heat while some said i should remove the thermostat, i don't feel the heat when the a.c is on though.
Secondly, i have been using plain water instead of mixing with coolant, how long can i go on with plain water?
Thirdly 2 days ago, it started overheating & i took it to a mechanic (rewire), the guy worked on it & the overheating stopped but now the sound emitted by d fan has increased & he said thats not a problem, i hope its not?
He (the rewire) also said i should remove the thermostat, pls what do u think?
