Hi i have a 94 celica ST with the 1.8L motor. I bought a used motor from online that had 132k miles on it. i dropped it in and i replaced the following on the car:
1. rear main seal 2. oil pan gasket 3. torque converter 4. radiator swapped out with 3 row performance radiator meant for gt4. 5. added a 15 row transmission cooler 6. new air filter 7. new spark plugs 8. new spark plug wires 9. new front o2 sensor 10. new fuel filter 11. straight pipe headers 12. high flow cat 13. aftermarket muffler 14. new belts all the way around and so when at idle everything seems fine and when i drive around town everything is fine but only when i get on the highway going 65MPH it starts to overheat very quickly and then i pull over and let it idle and it seems to go back down then i drive again and then at this point going any speed is making it overheat. i have no check engine light. and i checked the thermostat and it works and i checked the water pump and it works. i just flushed my cooling system and no luck there. I dont get why its overheating on me. I checked the compression and all cyclinders show 150. no noises are being made and when it gets hot the car runs fine no missing or other issues just gets hot. Anyone have any ideas? |

lol i dont know why people are saying do a compression test and get back to you with the numbers. sorry but did you not read the first post? i did a compression test and i got 150psi on all cylinders. however im not saying its not the problem just letting you guys know that i already did the test and it was posted previously.
ANYWAYS lol, i got the "Block Tester" which will tell me if there is any exhuast fumes in the cooling system. I got this yesterday so ill do my best to make time today to perform the test and get back to everyone  . And sorry if i didnt mention this before but when i bought the radiator it came with a new cap and i inspected it and everything seems in good working order.So heres what im hoping to accomplish today: 1. bleed the cooling system. if i still have the overheating condition then i will be doing the exhaust fumes in cooling system test. I will post back tonight with updates! P.S. You guys have been such a huge help in giving me advice on fixing this issue thank you a ton for everything guys! |
