got the head milled and new headgasket due to engine overheat
tourqed it all down to oem specs
put everything back together

started first time
waited like 20mine
thermostat still aint opened up
checked the engine temp gauge
it was 3/4 hot
so above normal
the head and top radiator hose was getting really hot
so we shut it off

tried to start it again
wouldnt start
just kept cranking

what could it be?
thermostat?
waterpump?

 

so ur thermostat is stuck? if where u live has decent weather, just take it out completely.

and it won't start now? sh** hope u didnt blow the headgasket again.

 

i hope not
it was a pain to change the headgasket
gunna swap out the thermostat later

 

Florida is considered good weather, and hot most of the time, and they had a 30's spell last week and the week before IIRC... swap your thermostat bro, don't take it out.

 

Don't remove the thermostat. It's needed to control engine temperature in any climate.

Check for spark and fuel. If you have both, compression test the cylinders.

 

i have no compression tester
gunna remove the thermostat and let coolant go inside the block
since the block and water pump is dry?

 

You need a new thermostat and to bleed the cooling system, but that's not preventing the engine from starting and running.

Is there bright white spark at all four spark plugs? Does the fuel pump prime? Any CEL codes?

 

fuel primes
no cel codes
i dont think the spark plugs are the problem?

 

Click the Check Spark link in my signature.

 

ok
so it starts straight up
engine temp gauge gets to 1/2 temp which is normal
top rad hose is warm
bottom rad hose it cold
i rev it to 2k rpm
temp gauges shots up to 3/4
what could it be?

ordered new thermostat
so waiting on that
hope the water pump dont need replacing

 

I'd replace it anyway if it's been 75k+ miles. Just to be on the safe side and have the reassurance in knowing that it's brand new. It's not expensive.
