freaky radiator thing

Where are you measuring the temp? the head or somewhere else? eletrical gauge or mechanical?

The manifold, before the thermostat.

I dunno man, some times it took a forever and a day run to get my car up to blowing hot air into the cabin.....

I have bypass holes in my remote thermostat, and so in this colder ~35f weather, the gauge says barely 150 or so on the freeway.....

computer sensor and mechanical cap tube are both into the heads.....


I have computer electric fans....so can idle forever to reach temp, but they WILL turn on eventually.....

:crutches:

Ok, so apparently this is not so abnormal.

Gene, I think your ecu will put you in cold start enrichtment continously when this happens.

It's the bypass holes that cause this for the larger part. However due to the absence of a bypass hole in the block and pump, the only other option besides the thermostat with holes, is a bypass line à la BB to the top of the waterpump.
