All that's printed on my spark plug wires is ACDelco 0745

Now I'm guessing again that this has been superseded, so does anyone know the new P/No?

 

I got my plugs, wires, air filter, oil and oil filter at advance auto parts.
Plugs- acdelco prfessional platinum pt#41-962
Wires- acdelco wire set pt#9748HH

Not sure what automotive shops the have in your location but they should be able to do a vehicle check and confirm what fits and what doesnt. When i got my plug wires they had short and long length. I got the long and they fit perfect without rubbing or getting in the way. Be sure you save the little metal covers that come off- you will reuse.

 

Thanks for that

Manged to get some from RockAuto (new part -number is ACDelco 748HH 10.5inch for a 2005 H2)

Here in UK we don't have vehicle check facilities for GMs, H2's and parts are quite rare here so we have to import which adds about 1/3 to the cost For example wiper blades can be found but not DEX-Cool.

Thanks again!

 

For example wiper blades can be found but not DEX-Cool.
Probably better off switching out the DEX-cool anyway I have had to replace more Dex-cool system radiators than not.

 

Indeed I've read posts that say the same.

Question is, what coolant is better?
