- Block check
- New radiator cap
- New lines to the overflow tank, including the pickup to the bottom of the tank
- New thermostat
- Check the waterpump
- burp the cooling system properly after everything is done

thx man will give those a try this weekend

Sounds like coolant wasn't burped properly.. The gauge spike sounds like an air pocket..

Hope that helps

And cut the jiggle valve off your new thermostat.

And cut the jiggle valve off your new thermostat.

This worked wonders for me! And when you burp your cooling system, make sure you've jacked the front end of you car up high enough so the Radiator cap is at least level to the top of your dash/heater core. If you dont, then you'll get an air pocket trapped in your heater core (Que waterfall sound). And good luck!

I hate having to link to ebay but you can pic this tool up from most parts stores for $20 makes life a lot easier when bleeding a system.
