Don’t worry, I know this radiator is shot without a re-core, I believe you guys that the flow is heavily restricted. The filter would be for the new radiator coming in the next month, since it seems like there is always new sediment showing up no matter how much we flush the system. My main goal...

Well we got some new results, seems like the last limiting factor is probably the debris lodged in the radiator cores. It’s about 70F out and we drive the car for around 40 min tonight. We got the core support seal in place. Car slowly heated up to 210, then we purposely let it warm up to around...

Sorry for the long pause, have been very busy this last week. Last night I drained the radiator and filled the system from the heater core hose until it reached the heater hose outlet on the pump housing then plugged it and continued filling until the coolant came up through the radiator cores...

Well I hope that it isn’t too bad. Was hoping to not do a block tear down since it has already been 3 years getting this car road worthy. I still don’t understand why the temperature drops 20 degrees in around 10 seconds when turning the engine off and on again. Its a mechanical gauge, so no...

There is no hood to radiator seal on my car… that is a good point. I always assumed it made some difference but not enough to cause my issues. I’ll get one of those on order to try it. I would still expect the engine to cool while at cruising speed though. Would the hood seal impact that a lot...

We flushed it very thoroughly. Flushed with the drain plugs out for around 20 mins with the engine off, back flushing the heater core occasionally, and flushed the engine while running for around 5-10 minutes still with the plugs out. Whole driveway was littered with debris that we got out. We...

For sure, I am sure the cores are well clogged. We have a Glenn Ray radiator on the way by the beginning of September, so that should fix that at least. Filter would be a good idea to protect that investment. I think I am having problems burping the system, since we drained about 3.75 gallons of...

The engine did have stop leak put in it to fix an exhaust bolt leak on the passenger side. I am now pretty confident that the problem is a blockage issue now though. I have never seen this much junk in the radiator before, I would guess the new pump stirred a lot of crap up. There’s a whole...

Sorry, I didn't provide much detail! So here is what the current situation is/what has been done. Situation With the new pump installed we took it for a drive. Outside temp was high 60's, so fairly cool. While driving continuously the engine was staying cool at around 180-190. We stopped for...

For those of you reading in the future, the flowkooler pump helped out a lot. The cavitation issue seems to be fixed and it takes a lot longer to overheat, but there is still something wrong with my cooling system! So far I’d recommend the pump if you are chasing down cooling issues.

It was collapsing when I got the car, put an appropriately sized spring in there and no issues with that now.

Well since the old pump seems in ok condition I could do that to have a good backup. It amazes me that it can move water with how much space there is behind the blades on the stock pump. As for the cavitation, we did a lot of troubleshooting to eliminate other causes. We know the car cools well...

Phew! I was worried something else was messed up! Thank you for confirming that

Just remeasured it, the exact ratio is 0.9536. Had it backwards though, water pump pulley is just a little larger than the crank, so under driven 5%

Well, definitely not 0.90”. Would be easier to measure with a feeler gauge.
