Coolant System Overhaul


Recommended Posts

So here it is I have a 97 850r needs heater core. Which is better to go with the Nissens at europarts or bahr at FCP. which is a better thermostat also the wahler at europarts or the vernat at FCP? How many gallons of antifreeze do i need to get was thinking just one but maybe two of oem stuff. Is there any better coolant to use than oem? i am going to this coming up making sure i get good parts. i also am doing hoses probly samco coolant and the ECT sensor.

thanks

joe

sorry to threadjack

but how hard is it to replace the lower coolant hose?

as easy as it is to drain the coolant.

as always, any job that requires you to do so, it's usually the biggest pain in the ass about whatever job it is because it usually makes a mess and you have to look for a place to dispose of it afterwards.

be careful you don't break the petcock - as you'll have an all new job to do.

other than that (providing your worm clamps arent toast) its nothing. Worst case scenario you cut the old hose off with a razor knife if its stuck...but it shouldnt be a problem.

Volvo does a great job with water hoses. I have never had one replaced in over a million miles on various Volvo's, mostly driven over 200K. I have never had service like that with hoses on other makes, so I would only buy OEM for this part.

are you guys replacing this just because or is it leaking?

Vernat t-stat is regarded as better. I would go with Behr on the heater core as well.

My experience with aftermarket coolant hoses: I believe I had an upper hose made by MacKay. Within 2 months, the inner ply had seperated from the outer and it seriously looked like it could pop at any second and send coolant spewing everywhere. They are bad news. Saving $30 is not worth blowing a HG or having to get the car towed. Both of these will cost significantly more than $30.

EDIT: Spelling
