Why did some Nigerians mechanics keep advising motorists to convert their fan to manual and get their thermostat removed?

Cos the heat is too much and the car will overheat.

Wow, Thanks

Yeah. What u need be aure of are if your fans are working .both the blades and the fuse are all working without it being burnt...if thermostat is there or not is irrelevant. Most times its closed sef. If everything is in order.and your hoses are not cracked or leaking. Hoses going to radiator and back to engine ac hose and heater hose..if they are not leaking and lastly ,your radiator cover still has tight grip,then fear not. Over heating can never happen. That's why your eyes should glance through temp guage at least 30 to 40mins while driving. If e dey rise,one of its team members is weak.....

Wow, Thanks

This is very wrong advice. Pls don't remove your thermostat and run fans direct. You will cause the engine to always run below the operating temperature, and your ECU will increase fuel entering the cylinder in a bid to get the temperature up. The fans constantly running will also weaken them and overcool your engine. Your fuel consumption will increase, your engine will likely have sludge and you'll be needing a replacement engine in no time.

Leave your car as it is. If you have an overheating problem, find the cause and fix it, not masking the problem with thermostat removal and fan conversion.

Also, while you're at it, find the recommended oil weight for the car and stick to it. Don't use 20W 50 as most "mechanics" advice. They are not smarter than the car manufacturer.

Why I brought it here is that, my mechanic converted my fan to Manual without my consent. I have reached out to some couple of rewire to change it back to automatic, they said "oga leave it like that" our weather is different from oyibob own" I always want my car to be the way it was created

This is not automanual. This bobo's car once overheated and had a blown head gasket. That time automanual never buy that homda accord.

Find a competent mechanic and confirm that your car doesn't have overheating issues. Once that is done, find a competent rewire and INSTRUCT him to change the fan back to factory setting.

Don't discuss with him, INSTRUCT him. If he wants to start saying rubbish, look for someone else. Don't let anyone spoil your car for you o. The people that made it have already tested it in hotter temperatures than the one we have in Nigeria, and the cars work fine.

Bro, 20w50 is written at the top of my engine as the kind of oil to use

You're wrong. Just buy a good car and use the right oil. Been using my car for 2 years now. No conversion of fan, no removal of thermostat. It has not overheated once ever.

Exactly. The worse your car performs, the better for their pocket, and they know it.

The recommended oil for your car is 0W 20 or 5W 20. Please Google it to confirm. No modern car has 20W 50 as recommended oil. None!

You are right! I just checked, the mistake is from me. Thanks bro.

Many thanks for your input, Can thermostat be replaced or being sold in the spare parts market?

I have used 20w 50 on my Toyota Matrix 2003 since I got it as Tokunbo 3 years ago. I wanted to change it to the recommended oil last year but my mechanic said the engine might react to it in a funny way. What do you think?

There's no easy way to say this, so I'll just say it.

Your mechanic is right. You've been using the wrong oil weight for too long, and switching now will likely cause your engine to burn oil and smoke eventually. I also have a 2003 matrix and I had to change the engine eventually when the thing was smoking like crazy. I changed the rings before doing this, but the same thing was the result after about 4 months. There's a nairaland thread about my experiences somewhere, if it would help you.

Your engine most likely has a good degree of sludge, especially if you drive for short distances/city driving only, plus use the 20W 50 for 4000, 5000 miles. Now, the correct oil for that car is a 5W 30 oil, full synthetic. If you do that, the synthetic oil contains cleaning agents that will affect the sludge and open up passages in your engine that have been blocked by sludge, thereby causing possible shortage of oil, smoking or in extreme cases, engine knocking.

I can't say for sure that this will happen to your engine, but I'm 80% sure it would adversely affect it based on the time you've been using the wrong oil.

Sorry bro.

Keep using like that and change at 3,000 miles max with a good filter. And maybe start saving for a replacement engine if you want, or you can sell as-is with full disclosure to the buyer.

My car is four years. I have been using it with thermostat as against all mechanic advice.

One removed it when I had overheating issue caused by faulty radiator. I got it returned back after changing the radiator. I never had a any issue with it. Special thanks to a nairaland mech who returned it back to factory default.

You later bought another thermostat? If yes how much please?

Thanks to this thread, I have bought a thermostat for my car. I am fixing it tomorrow and returning the fans back to automatic.
While doing this, is there any other thing I need to do? Do I need to take the radiator to car wash? Please tell me guys.
