Re: Over heating 302W
Hi Rhett ,
If you have Hydrocarbons mixing with the coolant, it is most likely to be from small leaks in the Head Gasket area, I have had this problem with my 460. Not uncommon with Fords, try a large bottle of Irontite Coolant Sealer and follow the instructions , to the letter, its a quality product. 14 degrees of advance seems a bit much , try backing it off a bit in stages, you should have no more than 32 degrees Total, this is critical in an LPG engine. ( I run 10 degrees Initial and 11 degrees in the Distributor, which is 22 on the Crank ALL in by 3000 RPM.
Have your mixtures checked with an analyser, Gas works opposite to Petrol, the richer the mixture on Gas the hotter the engine will run.
Another prob. you may have is if the engine has sat for a period of time with no water in the cooling system and you fit the engine back in the car, after the first few start up's, small lumps of rust and dirt come loose from the water jackets, partially blocking the fins in the radiator, unless you have a Radiator Filter titted. This causes overheating at higher speeds, but run's normal temp. at idle.
Frank Tonitto at Silverdale in Sydney, supplies a quality Rad. Filter. ( his number is 02 4774 2022 )and is in Just Parts Magazine.
