Im in deep guys. got a 2001 gti (145k miles)on my hands and it was overheating when idling for over 10 mins or so but when im normally driving it wudnt and my fans didnt seem to turn on when they were supposed to.

so i went to a VW dealership to get a diagnostic and this is what they told me.

New waterpump (480$)
New Thermostat(337$)
New Coolant temp. sensor(156$)
New Aux Fuse panel(200$)

now this is completly out of my price range and i just want my car to not overheat and my fans to work properly so i can have a.c. is this really what its going to take? or is there a way around this or a cheaper solutuion. also if anyone can help with sum tips if im replacing the water pump/thermostat at home. ty! please i need help haha

ok first off thermostat you can get one for 17 dollars, i did it myself, was an hour job, and thats just coz we were *****footing, when doing you will also need a new dipstick holder coz the ish will break when you try and take it out, plus some coolant, so your looking at around 45 for the thermostat doing it yourself, coolant temp sensor, thats a joke you can seriously do that in 10 minutes, just by the new green coolant temp sensor and replace it yourself its easy, i think its around 30 bucks at ecstuning.com, all these write ups or on vortex, id link you but im lazy, now that leaves you with the waterpump and aux fuse panel, those i have no idea about, but find a good euro shop and i bet theyd do both of those for way cheaper... wayyyyy cheaper, look to buy the waterpump and fuze panel yourself, and bring em to a shop you think is good and get a price prolly be way cheaper than the dealer

Actually a water pump job isn't that easy on these cars, and if you've never done one then you just speculate. If you do the water pump, change the timing belt. It's an absolute must. The thermostat I changed without breaking the dipstick, so that's just silly. And if you want a link for parts...

Temp sensor:

Thermostat:

Water pump:

Timing belt kit:

And if you want to do-it-yourself, here's a Bentley manual:

Tho a few of us can walk you through the process or provide links for all of the above.

Check the link I posted above. The coolant sensor along with the water pump and coilpacks are all known parts to fail. Consequently, VW released a newer coolant temp sensor not as prone to failure, which has a green colored top.

Coolant you can use anything as long as it's G11 or G12 from a dealer, the new G12++ is amazing, purple in color but a bit pricey. Also, for the fuse panel which one? The one on the battery? http://www.ecstuning.com/Volkswagen-Golf_IV--1.8T/Search/Fuse_Panel/ES248855/

Temp sensor relates to the fans, so you will want to replace that as well. Thermostat too. If you do everything at once it just helps prevent problems a few weeks or months from now...

Book is good for so much more than just those repairs, but if you opt out of the book we can post you a few links to a few sites that can walk you through everything

The site I gave you lists everything for MUCH cheaper than what you were quoted by the dealer. It's something I'd say do during the weekend, or whenever you have consecutive days off, it is a timely job. It can be done in a day, easily, but for your first time you want to make sure you give yourself plenty of time. And we're always here if you need some help
