    Overheating After Rad. & Timing Belt Replacement

    I replaced my timing belt (hope to never do that again) and I didn't have any problems there. I also replaced my radiator because the plastic part on the top of the factory one cracked. I now have an entirely aluminum radiator in there.

    Took the car for a drive and after about 2 miles it overheated. So, I blasted the heat inside the cabin, coasted and then came to a stop. It took a while to get back to the house doing the same procedures of stop and go all the way back. Note that NO HEAT was coming out of the inside vents.

    I checked all my connections from the radiator to the fill valve to the thermostat and even the over flow. There weren't any leaks and the strange thing was that the radiator and the hoses weren't that hot.

    Could this be a bad thermostat or does it have something to do with the timing belt? BTW, I lined up the belt with the cogs perfectly and checked the alignment of the cams to the correct alignment. I also manually rotated the engine via the main pulley and I had no stops and everything was smooth.

    Any help or suggestions would be greatly appreciated!

    Burp the system and then burp it again. Then repeat.

    when replacing rad did you do a complete "burp" that could be why hoses arent hot, and not prppper flow, should make sure you had burped it fully and that thermostat is working as well and installed correctly, timing shouldnt have that much to do w/ the overheating

    Thumbs up

    thanks for all the replies. To answer the question about burping the system, I didn't. However, between the time I posted this thread and replied, I added a little more fluid and squeezed the main hose repeatedly to get as much air out as possible. I took it around the block and it seems much better but still getting a little over the temp. range. I guess I will let it cool down and then repeat the process again.

    Thanks for the help!

    Let it cool down completely, stone cold. Remove the rad cap over the turbo reservoir between the suspension tower and the intercooler. Squeeze the top hose gently and repeatedly, and keep topping up.

    When I burp the car, it takes a long time, but I have yet to need to burp it with the motor running at all. This method is lengthy but with patience it'll work great.

    Since it responded to your first go then air in the system was the issue. Keep at it.

    I think its just me but I changed out my rad a few months ago because of a crack, to an all aluminum one and I filled my coolant and never burped it and never had any issues with overheating at all.

    Just thought this was odd because I never had this issue.

    It sometimes gets an air lock in the heater hose coming out from the bulkhead. Have the car runnning and remove the slightly remove the heater hoses until good flow out coolant tries to escape. Should be fine after that
