Vw polo overheating

Answer 1

What type of Polo are you using?

Check the following:

- Leaks - Radiator/ hose / Junction valves / water pump

- Check water pump if you see water leaking coming from the engine block then your water pump is busted.

- Try to squeeze the main hose after running for 15mins if hose becomes hard because of the pressure build up then the return portion of the radiator is clogged. Ask a mechanical to clean radiator.

- Check if your water on the reservoir is over flowing or has too much water. pump out water by squeezing the hose like an ambu bag. you need to do that because water cannot flow, Polo has a close circuit cooling system. Pressure prevents it from cooling down.

- If all of this above are ok then 2nd to the last is check water pump, it has a temp regulator that possibly needs to be changed or if you live in a tropical or fair weathered country then you can ask mechanic to take it out.

- Still if everything fails, check color of oil if it still oil then good but when it turns out white then your engine needs a top overhaul. what happened? gasket has worn out and water mixes with oil making it white or curd like.

- You might also want to check cylinder head alignment.
