I was cruising with my T2 last night, when i driving on the freeway the temperature go up to little bit after half, and then i get off the freeway, the temperature ran up to 3/4 (hot), i had change the radiator. Do i need to change the Thermostats or water pump? What cause me over heat? Could anyone help me? Thanks

 

WTF? You changed the radiator... got fluid in it ? Got enough fluid in it? Is the fan working?

yea...i did.

 

Take your thermostat out and drive it around a little, see if it changes. Perhaps your thermostat is stuck closed. Or you can take it out and boil it and see if it opens up. Either way, check the thermostat, check that you have sufficient fluid, and check that it's not blowing bubbles into your overflow canister.

 

What is blowing bubbles in overflow tank? Should i just change the thermostat?

 

Ok, take the cap off the overflow tank, leave the end of the rubber in the coolant that's in there, and plug the overflow line and while the car is idling, check to see if it bubbles at all, or if any white colored smoke/air appears. You can try changing the thermostat.

 

do i need to fill up the overflow tank?

 

Does it have any coolant in it already? It should have about 1/4th to 1/2 in there already

 

Thanks
