Warm up the motor with the cap off, then rev the motor to 3000 rpm and squeeze/pump the upper rad hose several times every once in a while like a nurse on a blood pressure checker pump thingy. This will get the air out. Then check the reservoir and refill after every cool down for a few days.

That sounds simple enough even for me!

Thanks Jason. I'll do that.

In the end, I know I'll face issues until I change the tstat housing to one from a 1.6L. I'm using my car's and the pipe goes up above the radiator cap and then almost to the bottom and back up to the upper side of the radiator. No wonder I have cooling problems.

The latest update:

After checking the water pump and bleeding the air from the system (as per Jason's instructions); I took my car out for a spin last night (I've been meeting with a group of friends every Thursday night at a restaurant for the last 32 years) and was surprised to find that my coolant temps would stay around 180* all the time on the way over there. I got cocky and decided to floor the accelerator to see what would happen. I'm happy to report that temps did not go over 195* at any time.

Here's the surprising part: 2 nights ago, I took the car out for a spin around the block and somehow my MAP line got disconnected. The car started to misfire and I went back home and parked it. Yesterday morning I took it to the shop and we had to take out the sparkplugs (Iridiums 7 series) and these were beyond fixing so they loaned me some 8 series plugs and suddenly everything changed. My EGTs went down 200 degrees and no more high coolant temp issues.

I think part of the problem was the plugs I was using and most probably the gap they had.

I love how my car is behaving with these new plugs. FWIW, I would recommend that anyone needing to control temps should buy the 8 series ones.

Many, many thanks to all!
