I had the frost plugs in my N/A 3B replaced in October and since then I have had a persisting issue of temperature spikes when climbing up long highway hills. (Squamish to Brohm lake for example)
Since then I have replaced my:
Rad cap
Fan clutch
T-stat OEM 82 degrees
Water pump
Various hoses including the lower rad hose
Flushed heater core
Installed an mech. Water gauge
And still no results.
It runs beautifully on highway flats and through town, even slight inclines but when I drive long inclines such as Squamish to Whistler it seems to not enjoy it so much. When it reaches the 110 degree mark i usually pull over and let it idle to cool. I’ve owned this truck for 7 years and it belonged to my mom before that and never had this issue with it other than a clogged radiator years ago which was recored.
The coolant is quite sludgey and dark. I’ve flushed it multiple times and had it professionally done but it stays that way unfortunentely.
It seems like the system is not holding pressure very well. It never came out of the overflow tank until recently when I tightened some hose clamps and now it seems to overflow so it holds a tiny bit of pressure when spiking but not much. The upper rad hose is easy to squeeze. Heat blows hot when at normal op. temp but then blows less warm when engine temps spike.
Timing marks are at factory settings.
Planning on doing a rad pressure test and take it in to a shop for a HG test. One fellow recommended Kieran in Langley. Does anyone know if he’s still working on cruisers? Seems as though I need a genius to help me and I’m more than happy to pay!!
Any other suggestions?
