What could cause bubbling in reservoir besides HG?


Recommended Posts

I got a block test kit and tested it from cold start all the way to 205 deg, and even a few hard revs. Some bubbling occurred in the reservoir, and my coolant levels have been funky for a while which is why I got the block test kit.

 

I also further inspected the head gaskets and they appear to be fine, what I had originally thought were the heads was actually the valve cover, which is leaking oil. So now I'm pretty happy as the valve cover gasket is a much easier and cheaper fix, but that still doesn't solve my reservoir bubbling issues.

 

I'm going to drain and refill the coolant according to the vacation pics, to make sure its purged properly. I replaced a cracked radiator a few months ago with a Koyo, and got a matching radiator cap from them as the OEM one wasn't really fitting. But if it's properly purged, the radiator cap is good, and the timing belt and water pump were changed 4 yrs/ 20k miles ago, along with a T-stat and whatever else is in a typical timing belt job.

 

So what would be next?
