Hi Guys, it all started when a friend saw ma old radiator cap and suggested to replace it as it was way to weak and there was obviously on pressure on the cooling sytem anymore. I purchased a new standard cap and replaced the old one.
After a longer ride the engine bay was completely wet but I could not locate where all that water came from. I thought of a defective cap and ordered another one.
A week later I saw water pouring out of the warter pump and thought of a blown gasket due to (now) high pressure on the system - I replaced the gasket and found out that the waterpumps shaft seal was gone.
I ordered a new aluminium (highflow) waterpump, replaced all gaskets and as I always wanted a more powerfull musclecar sound I added a "mild" CompCam Thumpr camshaft with new lifters as I was halfway anyway when replacing the waterpump.
End of the story is that the engine was now ok but running hot after 15 minutes. I removed the overflow canister so water can escape and putted a 160° thermostat in ... still running hot after about 30min ride - especially on a highway even when only riding 50mph. Looks like the engine keeps cooler when riding smaller roads ... even at higher average speed.
After all it looks like the old radiator cap was pretty good as it allowed the hot steam to exit thru the overflow canister and therefore the heat to escape and water to cool down.
Any idea what I could do next ?! Should I put a shroud on the fan - change the fanblades to flex or even change the whole radiator (does not look to bad) ?!
Btw is the Thumpr (CCA-CL31-601-5 ordered at summit) producing way more heat ?!
