Hello,
It was a month my vehicle running with out coolant. There were no long trips and no high speed rash driving.
We packed up for a trip and total distance was around 300 KM. First 45 KM was city limit remaining are ECR highway. Coolant tank filled with water which was the first and known mistake.
Actual coolant oil only need to fill up properly and what was the general assumption on water as a coolant? water does 50% of actual work done by the coolant. Many will agree on this but that's not a fact. The fact is water alone will increase the engine heat rather than reduce it , the main reason is coolant oil's boiling temperature is very high compared to normal water and it does not vaporize or produce steam.
Due to the heated water steam pressure, it spoil the seal in water pump while flowing through it.
So avoid water alone as a coolant. Keep in mind do not run the engine even for small trips with out coolant oil which will blow the engine gasket due to more heat. Engine like TDI gets more heat compared to normal diesel or petrol engine.
Replacing water pump may be an easy task but what are the risk involved ?
1. Timing belt need to be removed.
2. Removing water pump may spoil the belt tension.
3. Water pump should have cast iron pump attached which is way costly than the spare.
4. Timing belt configuration requires more time.
Time for a mechanic shed , this time Mahindra First choice in Mayiladuthurai.
Same story. "Sir ...Need to purchase the water pump from Chennai/ Coimbatore as VW brand spares wont be available here as it does not have more movement"
"one more day require to assemble the engine back as it has timing belt configuration"
Also i wanted to change the back wheel tyres. MRF 175/ 70 R 14 84T. 2 pieces. it cost around 3750 x 2 .
No need to mention it, no service charge for tyre replacement and wheel alignment.
Seal broken Water Pump.
Engine head and timing belt assembly.
Engine - removed top cover
Journey continues as life
