Question 2007 Matrix Overheating and No Heater

I am helping a friend with his 1st gen 2007 Matrix.
It has 400,000+ kms. He would like to get it through one more winter before purchasing another, if possible.

The tempurature guage was indicating intermittant overheating. The heater was delivering warm to cool. He changed the themostat. Now it overheats more regularly.o
He just added 1/2 a gallon of antifreeze but has not spotted any visual leakage; no signs of AF on the oil dipstick; no white smoke out of the exhaust, no leakage underneath the car etc.. The heater put out great for about 10 minutes and then the engine started overheating again.
He does smell AF in the car.
Can the leaky heater core contribute to engine overheating somehow other that simply dropping the AF level to an inopperative level??
It sounds odd to me.
I got him to check the fan, and the serpentine belt tensioner.
I think he needs a heater core but what else is going on? ... front of the rad obstructed with leaves and debree (am I clutching at straws)?

Which thermostat did he use? Was it OEM? If not, consider going OEM as a first step.

If there is coolant smell inside, it likely has a leaking core. If the core leaks, it will not only lose coolant, it will develop air pockets causing warm heat and overheating.

Additionally, I would ensure to properly bleed the system after replacing the coolant. Usually that is best accomplished by jacking up the front end and running the heat while filling. Prolonged overheating can lead to head gasket failure and may have already happened. A head gasket failure will obviously also cause overheating.

That is excellent hardtopte72.
Thanks a bunch.
I still suspect the replacement thermostat too. Yes it was an aftermarket unit. He will replace it with an OEM unit, if an attempt at 'burping' the air pockets doesn't yield results. While the front wheels are up on wheel ramps, he going to try to squeeze any potential air along the hoses and out, hopefully being able to add AF as a result of the displaced air pockets. If that doesn't do it, drain the AF, then refill while the front end is up.

If he can get the heater output, and the engine temp to stabilize, he will consider heater core replacement. I know stop-leak isn't a pretty fix but the car is high mileage and he doesn't want to throw a bunch of money at it. Just to make it through one more winter would be a success.

Absolutely essential the proper bleeding procedures are used when filling with coolant. 2nd option is to start it and shut if off when the temp gets to normal range, then top off when cold, both recovery bottle and radiator. It can take some time. If the air bubble is in the engine it will not pull coolant from the recovery bottle, so if the recovery bottle level is not dropping as it cools down, it's almost certain you have a bubble in the system.

I am sorry I didn't post the results right after I said I would. My excuse being I was recuperating from open heart surgery

My friend followed all the suggestions and procedures as they were presented to him except for one; the guy at the parts store told him he didn't think he had to try an OEM thermostat. So he stuck with his word instead of ours. I can't imagine why he would stop short there after all the time and expense he had already put into it. He gave up on it, and bought another car. He didn't say another word to me about it.

So we have zero positive results to report.
I say thanks to you all who pitched in to help!

I wish he would have done the thermo again. After all that.
Simple things sometimes take us down. Thanks

Of course the guy at the parts store will say that. Likewise, dealer parts counter guys sometimes say that all aftermarket parts are inferior, which is not always the case. A Thermostat is one item I prefer to be OE.


I had a bad experience with an aftermarket thermostat (on a Mazda/Ford). It was the "Murray" brand, sold at O'Reilly Auto Parts store. The Murray thermostat I purchased was made by MotoRad (which claims to be an OEM supplier). Also, there is another person on Toyota Nation who also had a bad experience with an aftermarket thermostat. I asked the brand and he responded that it was a Murray brand. Two strikes against Murray/MotoRad. Does your friend remember the brand? Lastly, as hardtopte72 mentioned, it could also have been the heater core or hoses to that leaking fluid or air. We'll never know.

check thermostat
check water pump
check temps at radiator hoses and heater core hoses - they all should be about the same

I've used Motorad branded (not re-branded) Thermostats before and never had issues, that's pretty much all Canadian Tire sells, so when I've needed one in a rush I've had no remorse using them again. All manufacturers have fails though, regardless of how well they're made.

Put old and new thermostat in boiling water and see which one opens more. Some manuals have specs for thermostat opening.
Infrared thermometer $25 from Harbor freight. Check temp of head hoses, radiator top and bottom.
