Frequently Asked Questions
How do I check my radiator hoses?
Squeeze each hose cold - a good hose is firm and springy, while a mushy, swollen, or rock-hard hose is failing. Look for cracks and weeping at the ends and clamps.
Should I renew the clamps with the hose?
Yes - rusty clamps do not re-tension well and are the usual weep point, so fit fresh clamps with the hose.
