Question about 1997 Volkswagen Jetta

1 Answer

One day I topped up the water on my 97 VW Jetta Trek and forgot to put the cap back on the expansion bottle. Well the antifreeze ended up all over the car and the fan control module beneath the bottle. The engine guage did not go high temp wise as I realized what I had done pretty quickly. I topped it up and now the car began over heating. I was about to change the water pump anyway and did this as well as the thermostat. The car still over heats. I did not notice any coolant on the dipstick and dom't think the heads are damaged. I was going to direct wire the fan to see if this helps, but does the fan make such a radical difference in stopping this car from overheating? Help!!!!

Yes vw is very dependant on the cooling fan coolant pressure and expecially coolant mixture, check the gasket on the expansionbottle, as that can cause problems too, anyone of these will result in overheating

My 1.4 corsa utility is overheating we have put in new water pump new thermostat but it still overheating

you may have a blown head gasket or you still have air in the system. take the expansion cap off fill water to the top. run engine and when thermostat opens squeeze the pipes all round the engine to help remove the trapped air make sure the heater is on full heat and number on fan speed. when the air looks to be out and the fan comes on to cool the engine down shut off the engine. if air is still there rev engine a few times this will force more water out so top up to the top and squeeze pipes, keep doing this till there is no bubbles coming out of the expansion tank. when done leave to cool down and then top up and put cap back on. if this doesn't work and you keep getting air in then you need to have the head compression tested, or do the same with a bottle of radweld in the system. use the bottle that works with antifreeze, do as before but with the radweld in. it will leave a copper coating around the system and header tank. this is normal.

Where can you find the radiator cap in a volkswagon bora v5

Janet, top up your coolant in the coolant reservoir/expansion tank it is the rounded bottle closer to the shock tower.. Remove Blue or Black cap when engine cold and top up, run engine till warm and recheck after cool and top up again if necessary. Make sure to have leak repaired sooner then later to prevent future costly repair.
Check the attached links,instruction and guides, Good luck
