Hi Everyone,
IÂ’ve read through a bunch of threads about this topic already and I still am stumped.
I have a 2000 3.4L 6 cyl with almost 300k. I have owned the vehicle for 4 years and it has been a beast I love it.
Two weeks ago it overheated. My first thought was thermostat failed. Ordered new from Toyota dealership. Then the following day I when it was fully cool I started for a minute and heard what I thought was the water pump making an odd noise just kinda whining new noise never heard it make before. Figured that water pump had gone out itÂ’s an old truck and probably never been replaced and same with timing belt. So, we replaced the thermostat, water pump and timing belt. All new Toyota equivalent pink coolant. Ran it and bled the system. Ran fine for one day then overheated again. Pulled the radiator it was disgusting. Put a good denso radiator in filled it bled it, ran fine for another day, drove it to work and back no problems stopped after work at the store left it running came out and it was overheated. Head gasket?? I donÂ’t want you believe it but thatÂ’s where IÂ’m at. Any input or advice? Thanks in advance.
