    2003 VY 3.8 constant spike in temperature

    Yes. Did exactly that. After scraping and cleaning and rubbing back the heads & the inlet manifold with wet and dry, I wiped it down with wax and grease remover then when it was clean , fitted the MACE LIM gasket & the manifold. It took forever.

    2003 VY 3.8 constant spike in temperature

    Update : took the VY for a test drive today. Went great for 145km. Then suddenly temp gauge shoots up , alarm goes off , "Engine Temp HOT" on dash. But comes back to normal running temperature within 20 seconds. Turn around heading for home. Temp needle creeps back up again 2 minutes later...

    2003 VY 3.8 constant spike in temperature

    Okay. Thanks for this info. Good to know it's completely normal when bleeding. Any idea why the gauge on the radiator pressure tester slowly goes down ? Sorry, I should have explained the original problem why I've done all the work on it so far. It was getting hot & spiking in temperature...

    Yes. Bought one of those u beaut Coolant Refill Funnel Kits - does a good job. Bleed screws were opened. Had a good look at the radiator , didn't seem to be weeping. Will try a different radiator cap. Thanks for your help

    2003 VY 3.8 constant spike in temperature

    Thanks for your reply. Heater is on full. Still working on bleeding the system. There seems to be an occasional air bubble coming up thru the funnel. Will take it for a test run & see how it goes. Then maybe bleed again

    So could I ask for some help here please? We have acquired a 2002 VY wagon & a 2003 VY Ute , both with various issues so we need a scan tool, hopefully not too expensive. Would the Vident i400au be a good choice for my home mechanic partner? And would it work with an iPhone? Do I need extra...
