My lower hose busted and I am traveling, anyone know what size the hose is (diameter) and what coolant is compatible that I can get at a auto parts store?

I can't find my reference data on size etc. I'll check another computer and see what's on it. Doesn't sound like an easy road side fix. Good luck.

Regards,

 

Yeah, I saw that. It does not show the short hose that actually goes to the radiator.

Thanks

 

I got a hose repair kit and fixed my leak and for those wondering the inside diameter is 2". The repair kit I used came with a 1 3/4" connector, which I used and just clamped it down. Got the kit from Advance, also ordered new hoses which was just over $400 for all hoses (Ouch).

 

And I used Prestone Extended life, it is very close to the oem formula.

 

good to know randyb - glad you got it resolved, albeit a tad pricey!

 

So I got the new hoses and quickly found out they were for the 08+, so I got a 20" flexible hose from Napa and got the car back on the road. They had 17" and 24" also, but the 17 was to short and the 24 was to long. You could make the 24 fit, it would just be resting on the skid plate. I used Prestone Asian/ European formula 50/50 coolant. You will need 4 gallons, because the car takes just over 3 gallons and flush out the old coolant.
